Known Bugs

This page is for a list of bugs that were discovered. They are separated into Confirmed and Patched.

Bloons Games

Determined Pac-Man Glitch

Hey pacman, are you supposed to be there?

• This happens on all Bloons Games excluding Bloons Junior.
  When a Pac-Man Bloon is popped and the player clicks main menu before it disappears, Pac-Man will still be there, and it can still go anywhere around the main menu before the time runs out. (link to video)

Exploding Ice Bug

• 

  You spin me right round baby right round like a record player baby right round round (Click the image for full results.)

  This happens occasionally in some Bloons World levels. When more than half screen is filled with Bomb Bloons, only some of them will pop, then they suddenly freeze and explode. There is no exit from this glitch other than closing the player's browser. This can be tested on the Bloonsworld level 759 or 3796143. (link to video)

Frozen Pacman Bloon Glitch

• If a pacman bloon gets frozen, it doesn't appear to be frozen, but it can't be popped unless the Lightsaber Bloon, the Bomb Bloon or Pacman from another Pacman Bloon touches it.

Spike Rubber Bypass Glitch

• Very often, when Spikey Bloons fall down and there's a Rubber Block under them in a position that is not the lowest row of the screen, the spikes will bypass the Rubber Blocks and will fall off the screen. This can be tested on the Bloonsworld level 1265859(more effective) or 3795343(less effective).

Dart Rubber Bypass Glitch

• When the dart gets in a position which is surrounded by 5 or more metal blocks, the dart will touch the Rubber Blocks like if it does only one bounce then it'll go in the opposite direction: if in the same direction there immediately is another Rubber Block, the dart will bypass it. This can be tested on the 46th level in Bloons Player Pack 3 (whose Bloonsworld code is 1100657): however, it requires a very careful aim, as to complete the level the dart must go rightwards popping the other bloon.

Dart Rubber Bypass Glitch 2

• Throwing a dart at a Rubber Block being close to the monkey will make the dart bypass it. This can be tested on the 50th level of Bloons Player Pack 1 throwing the dart rightwards at high power.

Quicker Bonus Dart Bloon Popping Glitch

• Sometimes the Bonus Dart Bloon can get popped when the dart is close to it, but not over it. This can be tested on the 37th level in Bloons Player Pack 3.

Quicker Bomb Bloon Popping Glitch

• Throwing a dart at a Rubber Block/Metal Block being close to the monkey, at high power will let the dart bypass the block and pop the Bomb Bloon, if there's one. This can be tested on the 12th level of Bloons Player Pack 2 (whose Bloonsworld code is 594832 and 3795344) by throwing the dart leftwards.

Not Popped glitch

• When the screen is completely filled with Tack Bloons or Pacman Bloons, some of those may not get popped. This can be tested on Bloonsworld code 3795326 (tacks) or 3795338 (pacman).

Revolving Boomerang glitch

Come back, boomerang!

• Occasionally, when a boomerang comes close to the monkey after flying a circuit, it stops androtates on the spot. Sometimes, the player will have to restart the level to make it vanish. Other times, it will eventually disappear. To make the glitch happen, the player has to throw it directly to the right. It can be tested on Bloonsworld code 3796656.

Hot Air Bloon

Vanishing Monkey Glitch

• When the hot air bloon pops at the very top and the monkey falls, the monkey vanishes before reaching the trees (probably intentional).

Invisible Pursuer Glitch

• When the monkey falls, a board comes up saying the player's score and the player's highscore. However, the player can still hear bloons popping until the player makes the game reset (by trying again or going back to the main menu

Bloons Pop 3

Hint Glitch

• After earning 200 points, the player has unlimited hints, even if the player has no points. Even though Bloons Pop 3 is a few years old, Ninja Kiwi hasn't yet patched the glitch, and most likely never will..

BTD1 (and BTD2)

Iced Bug 1

• Sometimes when the Ice Tower attacks, some bloons will stop but not appear to be frozen.

Hypersonic Speed Tack Shooter Bug

• 

  There is no need to be upset ♥

  If the player presses tab until the Faster Shooting box is surrounded in a yellow box while it can be afforded, press the space bar until the attack speed is hypersonic and the upgrade is bought. Then, most bloons can't get by that tower. The player will lose money since the player couldn't originally afford it. This glitch can be done by other towers (such as Dart Monkey with infinite piercing darts, Ice Tower with unlimited freeze time, Most Towers With Infinite range(Still Shoots Just As Far!)), however those do not actually work.

Buy for Afford glitch

• Sometimes, after the player accomplishes the Hypersonic Speed Tack Shooter bug, part of the "Buy for" button appears in the "Can't afford" screen for the upgrades. This usually happens with the Tack Shooter the player does the glitch on, but it can happen with any tower, as shown by the slideshow below:

• The "Buy for Afford" glitch.
• Another occurence of the Buy for Afford glitch
• Yet another occurrence of the Buy for Afford glitch
• Even more occurence of the Buy for Afford glitch.

1/4

BTD2

(Every BTD1 Glitch works in BTD2)

Laser Vision Bug

• In BTD2, the Laser Vision upgrade pops frozen bloons, but it makes the sound a sharp projectile when it hits a frozen bloon.

Double BOOM! Bug

• When placing a Bomb Tower, it will shoot a bomb, then after the bomb explodes, another explosion sound is heard. Though, the second bomb is not fired or detonated.

BTD3

Huge missile bug

• 

  DEAR LORD...

  Sometimes, when the Missile Launcher shoots it will shoot an abnormally large missile. As seen on Superjombombo2's throwback series E5 (Seen on picture on the right)

Lack of Money Bug (Very minor)

• 

  Isn't the beacon supposed to be more expensive?

  In BTD3, the player can place a Monkey Beacon when the player can't afford it. The player can choose where to place it. However, it says not enough money. and it won't be placed. It doesn't happen with all the other towers.

Monkey Beacon bug

• This works only in BTD3. The player must have a Monkey Beacon with the Monkey Storm Beacon upgrade, it will allow the player to activate Super Monkey Storm. Then, sell the Monkey Storm Beacon, the Super Monkey Storm will still be there and the player can use it unlimited times without having the Monkey Storm Beacon, despite the description of the upgrade says that it allows it to call Super Monkey Storms.

Super Pineapple Explosion bug

• In BTD3, sometimes the Pineapple will pop 2, or even 3 layers of bloons.

Melee Bug 1

• The boomerangs/glaives that the boomerang/glaive thrower is holding count as projectiles, meaning any bloon that runs into them will be popped. Strangely, the held boomerangs/glaives do not appear to have a pop limit. Also, the player can't see it, so it could be the one on it's head.

Start Round Glitch

• On the first track in BTD3, sometimes there will not be a start round button after a round. The player has to use super monkey storm to get the button back. This is more common on easy difficulty.

BTD

Orientation bug

• In HD versions of Bloons TD, when the player adjusts the volume, the orientation appears to be sideways even though the orientation is completely normal.

BTD4 only

BTD4 Challenge Restrictions bug

Hey, that dart monkey shouldn't be there!

• In the Sweet Tooth challenge (pass in Easy mode using only Dartling Gunners and Spike Factories), the player can use a Dart Monkey by pressing it's hotkey (D). It will still attack.

Beacon Bug

• In BTD4, some towers covered by the Monkey Beacon's range will not get affected by it's additional effects.

Corrosive glue is not corrosive bug

• Sometimes in BTD4, the glue gunner's corrosive glue will not pop bloons on fast forward.

Spike Storm glitch

• The Spike Factory's final upgrade, Spike Storm will sometimes only cover up half or only a fourth of the screen in BTD4.

Road Spikes Not On Track

Huh?

• On BTD4, if the player hovers Road Spikes half on the blue space with the player's rank, XP, round, and the Pre-Round Comment, the player's NK account, or the final side of the track, the player can place the Road Spikes there, even though they can only be placed on the track.

Rank 99 bug

• In BTD4, when the player goes up to rank 2, it says that the player has rank 99, but on the other rank thing at the bottom, it says rank 2. Players can get very excited over this, but it's actually a bug.

Black Patch Glitch

Magi Monkeys can hover over the void by gravity defying powers!

• Around Round 80, A black patch will apear where alot of action is going on. There is no known fix to this. Also sometimes, the spikes fired by a spike factory have a black square around them. (This may be just an imagination, but this seemed to happen more often when a bloon buster mortar fired at a spot within the spike factory's range.) This happens due to the fact that the computer can't handle all the graphics. Happens earlier on tracks with complicated backgrounds.

Medal Glitch

• If you complete, lets say Ocean Road easy, and you complete a challenge, that Ocean Road easy medal will disappear, but a new medal will show up under what you just did (MOAB madness: Kiwi medium, Lollipop challenge: Lollipops easy, etc.)

Upgrade Glitch

• Upgrade anything to level 3 or higher, then as it's upgrading, buy another tower. That tower will show the same upgrade for the other tower. You just skipped a couple of upgrades! However, lets say you skipped all the upgrades but the sun god, your super monkey will have a small range (sadly).

Place Towers Anywhere

• This glitch allows you to place towers anywhere on the map. First, click on the tower you want to place. Then, right click anywhere on the track where you ARE allowed to place that tower. While the

dropdown is still there, click where on the screen you want to place the tower.

BTD4 and BTD4E

Round 0 Bug

• Sometimes before you start a game a comment will appear saying "Round 0 passed. 99 money awarded", but you won't get 99 extra cash.

Leveling Delay Bug

• Whenever a tower is upgraded, it's "level"  (shown above the selected tower's name) stays the same until the player either clicks it again or deselects it and selects again.

Dartling Gun Bug

What is a dartling monkey doing in the middle of the road?!

• Bug 1: Sometimes in fast forward, the Dartling Gun shoots 2 streams of darts. It is more common when it is upgraded to Increased Barrel Spin.
• Bug 2: (Does not work with Laser Cannon) When Fast Forward is active, sometimes the Dartling Gun's shots reach bloons; the darts will not pop the bloons.

Double Missile Bug

Double missile glitch (This should be an upgrade!)

• In BTD4 or BTD4E, if the game is in fast forward, briefly a second missile can be seen launched from the Missile Launcher.

Iced Bug 2

• This bug is very rare. When a bloon is frozen by an Ice Tower, the bloon will stop forever, and it cannot be thawed or affected by the towers or road items, and the player needs to exit the game. This is more common in BTD4 and BTD4E.

Skip Round Lag Bug

• Sometimes, when the player starts a round in BTD4, BTD4 expansion, or BTD5, the game will freeze, and then the round will be completed. The player will get their reward money, but no bloons will appear on the screen. This is a lot more rare in BTD5, but it is most seen on slower computers in BTD4. It happens most often in the first few rounds.

Melee Bug 2

Ice Tower! Give me back my boomerang!

• The boomerangs that the Boomerang Thrower shoot, will not return to the tower; instead, they will vanish at about 2/3 of the way (with Fast Forward on). And even if Fast Forward is off, the boomerangs will not pop any bloons after that, but they will still be present. This does not happen in BTD4 iOS.

Explosion bug

• In BTD4 and BTD4 Expansion, if there is a large amount of bloons that the Bomb Tower attacks, the game will not show the explosion, but only the frags (from the Frag Bombs premium upgrade). This can also happen with the Mortar Tower; it only shows the bloon's layer popping. This is caused by lag.

Road Spikes Jump bug

• In BTD4 and BTD4 Expansion, there is a glitch where fast bloons can travel a short distance over road spikes before popping, causing the bloons that spawn from them to miss the road spikes completely. This also happens with the road spikes produced from Spike Factories.

Wacko Spike Factory Glitch

A wacko spike factory doesn't know where is the road.

• If placed far enough from the path on any given track, the Spike Factory will randomly place spikes on the border of it's "search" radius.

Loud SFX Glitch

• When you unlock the Super Monkey at Rank 15, you will hear the unlock sound effect, but way louder than usual.

BTD4E only

Pineapple Bug

• In this game, if you use a pineapple, you can see a second explosion behind the pineapple explosion.

Banana Farm On Deflation Bug 1

• 

  HEY! THAT'S CHEATING!

  It is possible to get a Banana Farm on Deflation by pressing it's hotkey (F), however, it gives no money.

Black Area Bug

• In Bloons TD 4 Expansion, and on the Subterranean Sewers track, around round 45, there is a bug similar to that on BTD4; a black patch may appear in the middle of the track. It gets bigger and smaller at the edges, but it gradually gets bigger, covering a 3-4 inch square of the track by Round 50.

Track 6 Bug

Not really much of an achievement

• If the player plays track one on BTD4 expansion and save, and then when the player goes to the original BTD4, it will take the player to Firecracker. Also, if the player quits BTD4 and reload the save, the player should click on Resume Game. The player might see a message saying Congratulations! You passed this track on null. The player can also earn an achievement for this.
• If the player clicks "Keep playing in freeplay mode", then the player just starts from whatever round the player was at when the player quits BTD4. The player can even save.
• Beating the track on the difficulty it was on still gives the player the You beat this track on (difficulty) notice, and then it becomes freeplay.
• Sometimes, the player can't click Resume game. When this happens, go to any track, and the player has passed it on null.

Specialties bug

• In BTD4 Expansion, if the player uses the Vehicles specialty, it reduces the cost of Monkey Buccaneers and Monkey Aces, but it increases the cost of their upgrades.

Error by creating new towers bug

That's one weird-looking spike factory!

• In BTD4 Expansion, and in the towers menu, when the player hovers the cursor on the Dartling Gun or Spike Factory, it shows the image of the Dart Monkey instead of the image of the Dartling Gun/Spike Factory.

Locked Bloons Bug

• In BTD4 Expansion, the player sometimes cannot play in the Subterranean Sewers track. If the player clicks Start Round, the round will only send up to 5 bloons (the other bloons will be locked at the beginning of the track), and if they reach the exit, the player loses lives, but the player can't start the next round. Then, if the player quits the game and play on another track, the locked bloons will remain on the track, and the player's towers cannot pop them.

Covered Menu bug

Covered Menu bug

• The tower description is covered by the bottom of the screen. See the photo for more.

BTD4 iOS

Monkey Ace Bug 1

• In the Monkey Temple track, if the player puts an un-upgraded Monkey Ace before starting round 66, in the current round and round 69, Monkey Ace will shoot 6 darts instead of 8. This is more likely to occur if the player is playing on Hard difficulty.

Non-Arctic Arctic Wind bug

• In BTD4 iOS, Ceramic Bloons popped from a M.O.A.B. do not get slowed down by arctic wind if they are popped in it's Range. The Bloons can still get frozen, however.

Playing after the player loses bug

• In BTD4 iOS, there is a glitch where if the player loses, and the player exits, and re-enter the saved game, the pause screen will appear; and if the player taps the resume button, the game will play for one frame. Towers will shoot, Bloons will pop, and the player can even get rounds to end, and even start the next round if the player taps the button during the one frame that the game is playing. Unfortunately, entering and exiting the game multiple times to keep playing is a very long and boring process.

Unplayable bug

• In the mobile versions of Bloons TD 4, "monkeying around" with the menu buttons might cause the player to be stuck on one screen, forcing the player to restart the application.

Unachieveable

• A severe bug causes achievements to disappear, even if the player has gotten them.

BTD5: Towers  

Blinking Hotkey Bug (very minor)

• When you select a tower and then press the hotkey for the same tower without placing it, the range circle will blink red for 1/10 of a second. Probably intentional since the circle blinks red when you select a tower, so you basically re-place it.

Lag Bug

• Bug 1: In BTD5, if the player clicks the Sell button very fast, the player can click the button 2 times and the player gets twice the money. Happens frequently in laggy computers.
• Bug 2: On laggy computers, if the player has only one tower with an ability, and if the player clicks the button many times during a lag spike, the ability can be used more than 1 time (for example, the player has only one Spike Storm ability, but the player can use it 5 times). This makes some abilities more efficient. 

Ability Locking Bug

• In BTD5, if the player loads a game that has towers with abilities, the abilities become unusable until they recharge again (this is probably intentional to prevent the player from getting a "cheating" kind of advantage). Precaution: Only save at round 1~46, 49, 59, 69 & 79 to avoid unusable ability.

Double Fire Glitch

• If upgrading a tower when it is doing the pre-firing animation, it will have its attack interrupted, and will instead fire two upgraded shots afterwards

Hypersonic Spike-O-Pult Glitch

I almost feel sorry for that MOAB.

• To accomplish this glitch, the player needs a 2,0 Dart Monkey and a 0,4 Dart Monkey. Then, the player should activate the Super Monkey Fan Club Ability and upgrade the 2,0 Dart Monkey into a Spike-o-Pult, but it is only hypersonic for 10 seconds. This also works on Juggernaut as well, allowing the player to easily obliterate ceramics and MOAB-class Bloons.

Infinite Range Fan Club Bug

• Use super monkey fan club many times (If you're lagging while doing so you have a higher chance) and it should eventually show the range equivalent to a Sniper Monkey (the small range circle) http://puu.sh/56V5u.jpg

Hotkey bug

• When using the Dart Training Facility (Level 3) building, and if the player uses the hotkey Q for placing a free Dart Monkey when available, but the player doesn't have enough money for placing a normal Dart Monkey, the hotkey Q does not work, and the player has to use the button in the tower menu to place the free Dart Monkey. The same goes with Spikes R Us level 3 building with the Road Spikes.

Harmless Towers

• If the player gets 6 MIB Call to Arms and a 2/4 Boomerang Thrower, and the boomerang thrower is within the range of the MIB Call to Arms, activate all 6 MIB Call to Arms, and then a second later, activate Turbo Charge. For a few seconds, the Boomrang Thrower will shake around. Then when the MIB Call to Arms ability ends, the Turbo Charge will act like a normal Turbo Charge (On fast forward, this doesn't happen).

I Don't like Red Hot 'Rangs bug

• 

  Where's my red stuff? :C

  If the player has a Glaive Thrower and upgrade it to Red Hot Rangs, the glaive in the monkey's hand looks like a normal glaive until the monkey throws it, then it comes back to the tower, and it becomes a Red Hot 'Rang.

Ninja Always Seeking Bug

• Sometimes, an x-0 ninja monkeys shirukens will seek anyways, even though you haven't upgraded him to do that. Cannot send his shirukens far distances if this is active, but can make course corrections to the weapon.

Ninja 1/1 glitch

• Conversely, sometimes a 1/1 Ninja doesn't seek.

Melee MOAB Assasain bug

• Bug 1: Sometimes a MOAB assasain will instantly kill a MOAB-class bloon with its normal shooting attack when you haven't used the ability. For example, a MOAB assasain is attacking bloons when a MOAB comes. You don't click the ability, but when the tower launches the missle like normal, the missle will kill the MOAB in 1 hit. Like the ability, it does 1000 damage to ZOMGs with this bug.
• Bug 2: This is rarer than bug 1. If you have a MOAB assassain and click the ability, the tower will only do its normal damage to the MOAB. Like if there's a MOAB, and you click the MOAB assassain again, the tower won't kill the MOAB but just do 10 damage to lt like a MOAB mauler.

Popping-less Bug

• Glue Gunner's pops are inaccurately measured when multiple bloons pop at the same time (from splitter bloons or splash upgrade). For example, a White Bloon is glued. White layer counts as one pop, and the resulting bloons pop simultaneously, so the two bloon pops count as one.

Meerkats don't like Corrosive Glue Bug

• Normally, a 2/2 Glue Gunner looks like a 2/0 Gunner. However, when placed within the range of a Meerkat Spy, they'll look like a 0/2 Glue Gunner.

Monkey Pirates Glitch

• If you buy a monkey buccaneer and upgrade it to monkey pirate,the Moab takedown ability will still be in effect if you sell the tower while taking down a MOAB or a BFB. This will cause the MOAB class bloon to look as if it's being dragged to the bottom of a lake.

  

  Pirates of the Caribbean V: Monkey Pirates Glitch

Co-Op Ace Private Hangar Bug

• On Android, If the Ace Private Hanger is activated while playing in Co-Op mode, Aces do not have the auto-aim dart attack.

Monkey Ace Bug 2

• 3/0 Aces can target Camo Bloons but it cannot pop them. 4/1 aces can drop pineapples at the Camo Bloons, but the pineapples can't pop them.

Blind Dart Storm

• Sometimes, when upgrading Spy Plane to Operation: Dart Storm, the tower will start to look directly at the right instead of rotating. It's only an appearance glitch and does not affect the gameplay. The glitch fixes itself when upgrading to Ground Zero. This is because of the Sniper Monkey ability Supply Drop Ability.

Spectre stole Ground Zero's ability

• If you buy a tower, make their white outlines appear then click, upgrade to 1/3 or 3/1, sell, and click

  

  Spectre with Ground Zero's nuke. The Bloons are planning a hasty retreat.

   very rapidly. It will show the upgrade section where you can upgrade to 4/4.  Only Monkey Ace is allowed to still attack, every tower else is gone forever, so you can have a Spectre with Ground Zero combined. Through still every other tower being disappeared, they can still be upgraded to their ability, but the tower is still not there, being extremely useful for Daily Challenges where they restrict the number of towers with abilities.
  • Sometimes, when the bannana farm tier four upgrades are unlocked, on some games, the game says how you have not unlocked this upgrade yet. This glitch is actually intentional. It happens if either you're not the rank but you have unlocked it with XP or you're the rank but you haven't unlocked it with xp. It can happen with any tower.

Temple on weird angle bug

• Play one of the tracks until you get a temple. Save, then quit the game. The next time you play, the temple will be on a weird angle (only works sometimes).

Seems legit.

Temple outline bug

• Similar to Temple on weird angle, but this time if you place the temple and look at its white ouline, it will be on a different angle as the temple. 

Temple of the Monkey God Bug

• 

  Oh great and banana-craving one, not to bug you, but... I think your front lights are on. (May need to view full image for best result)

  When the Temple of the Monkey God stops firing, it's eyes will be blinking as if it is still firing. This bug was removed but it unfortunately came back when three new tracks (Fireworks, Tunnels, and Country Road) were added.

Outside the Range bug

• Sometimes, the Super Monkey will attack out of its range, even when there are no M.O.A.B. Class Bloons.

Double Village Glitch

• If you place a tower in the range of 2 Monkey villages, only one will affect the tower. The other will have no effect. This may or may not be intentional. 

Harmless Towers

• If the player gets 6 MIB Call to Arms and a 2/4 Boomerang Thrower, and the boomerang thrower is within the range of the MIB Call to Arms, activate all 6 MIB Call to Arms, and then a second later, activate Turbo Charge. For a few seconds, the Boomrang Thrower will shake around. Then when the MIB Call to Arms ability ends, the Turbo Charge will act like a normal Turbo Charge (On fast forward, this doesn't happen).

Monkey Village Harming Bug

• Placing a Monkey Village near a Bloonberry Bush will unintentionally reset the amount of spikes it has.

Radar Scanner Trick Bug

• When a Monkey Village is upgraded to Radar Scanner, it won't grant Camo detection to other High Energy Beacon Monkey Villages.

Mortar Tower SFX Bug

• After buying Bigger Blast, the mortar explosions will not be heard. This does not apply to the iOS version.

Dartling Gun:

Excuse me, not to be rude, but your gun is firing the wrong way.

Bloon Area Is Blind Glitch

• Sometimes, if you have a dartling gun upgraded to Bloon Area Denial System and no bloons incoming, the gun will fire straight up, no matter where you aim it. Weirdly, this does not work with Hydra Rocket Pods. Rockets can still pop bloons when this way. Aims normally when bloons come. On Sandbox mode in BTD5D, the gun will fire this way when you haven't sent bloons and none are onscreen.

Wacko Spike Factory Bug

File:165px-Wacko Spike Factories.png

Wacko Spike Factories II

• This glitch also happens in BTD5 (See here for more details).

Monkey Village Harming Bug

• Placing a Monkey Village near a Bloonberry Bush will unintentionally reset the amount of spikes it has.

Allergic Meerkats Bug

• Normally, a 2/2 Glue Gunner looks like a 2/0 Gunner. However, when placed within the range of a Meerkat Spy, they'll look like a 0/2 Glue Gunner.

Unlimited NK Coins/MM Glitch

• When the player purchases MM with NK coins, the player won't lose MM when the player buys Special Agents, nor NK coins. See: Here,or here.

BTD5: Gameplay

Slow Motion on Co-Op Bug

• When the player deactivates fast forward, the game will pause, then it will resume in a slower speed (again, this is based on connection).

Co-Op Money Glitch

• If the player gives money to their ally, it won't show (e.g. if their ally has 350 cash, and the player gives them 350, they'll have 350 unless the player closes the "transfer cash" tab and open it again.

Co-Op Ace Private Hangar Bug

• On Android, If the Ace Private Hanger is activated while playing in Co-Op mode, Aces do not have the auto-aim dart attack.

Undo Tower Placement bug

• Sometimes in Co-op Mode, the game does not allow the player to place towers, sending the message Tower placement declined. Your ally placed a tower there before you, and the player needs several tries before placing them. This usually occurs when the player is on low quality and the player's ally is not, making the game detecting the tower on an illegal position (for example, in the opposite side), or when the player places more towers very close to each other.

Ending Round with Bloons bug

• When playing in Co-op Mode, sometimes the round will end when there are bloons remaining on the track. They can still be popped. If the player leaks bloons, the player will not lose lives (Sometimes, the opposite happens: a round takes a while to end, even after all bloons have been popped). This is caused due to severe lag and can de-sync the game (making the floppy disk orange).

The Teleport Bloons Have Been Added in co-op bug

• On a laggy computer, if you play on co-op and you get a big lag spike, all bloons on screen (including MOAB class bloons) will skip very far in the map, and mostly to the exit. This bug tries to fix itself by freezing the game completely, but it doesn't work. Sometimes they don't count as leaks, but most of the time they do, resulting to a loss. This bug makes it very difficult to win a co-op track on hard.

Short-Lived Bug

• Sometimes, the game messes up on how many rounds are left for the player's tower in the mission. Most commonly, it skips a round, so the player's tower(s) only has 9 rounds instead of 10.

North Pole track bug

Is the track... a piece of wood?

• Sometimes, the North Pole track doesn't appear correctly in the "Tracks" menu. You can fix this glitch by closing and opening again the menu.

Reverser Difficulty Bug

• Advanced Reverser, Expert Reverser or Extreme Reverser can be achieved on any difficulty.

Game Over after new game bug if it's laggy

• Sometimes, when the player loses a game, and after the player starts a new game, the game will show the pop-up that says the player lost the previous game (and the round where the player lost).

RBE bug

• In Apopalypse Mode, the RBE of the round does not change; it stays at 24independently from the round the player is playing.

BTD5: Menus and Buttons

Go Button Glitch

• On laggy computers, sometimes the Go button will appear when a round is not done. Also, the Go button can appear in Sandbox mode.
• If you click the button when that happens, you'll see the next wave of bloons come as well as this round's bloons.
• If it appears in Sandbox mode, and you try to send bloons, the bloons won't come until you hit the Go button.

Glitchy Chest Bug

• Sometimes, the player can't click on the Monkey Money chest. Refreshing the game helps.

Main Menu Bug

Can't I take a break from the popping!

• When the player wants to leave a game, and sometimes when the player leaves the border of their previous game, Towers, Special Agents, Lives, Money, etc. Will be around the Main Menu (see picture).

Main Menu Glitch 2

• This is sort of the opposite of the main menu glitch; if the player clicks the menu button, the game will still show, but not the border.

Delicious Banana Glitch

• In BTD5, if the player clicks play while the title screen monkey is eating his banana, the eating sound will continuously play with no end, even when the player goes onto a track. The player can fix this by refreshing the page or closing the browser then going back on the game (this also happens with the other title screen sound effect after the logo comes up; that sound is the monkey falling). This can also happen with the fireworks sound.

Playing In Main Menu bug

• When the player is severely lagging and clicks the home button many times in quick succession, and clicks yes, then play another track, there will be another box saying Are you sure you want to quit?.

Achievement Glitch

An example of the Achievement glitch. Is this some fancy new pig latin?

• Sometimes, when the player taps on a achievement and wait, it will become invisible, but some letters of it will remain.

White Screen Glitch

No, this is not what Absolute Zero looks like.

Dart monkey, that's not a bloon.

• Sometimes, with a bad connection, and when the player loads BTD5, it loads like normal, but the player logs in as a guest. After a few seconds this happens: (see photo)
• It sounds like the "monkey eating banana on top of the BTD5 letters" screen. If the player clicks GO!, nothing happens. Clicking on the dart monkey will cause the monkey to appear on the top left corner.
• It says round 12345678 and RBE 1234567 at the bottom of the screen. 

BTD5 Deluxe

Non-overclocked tower Glitch

• To achive this glitch, get any tower and a Monkey Engineer upgraded to Overclock. Then use overclock on the tower. You'll notice it shoots hypersonic. Then, while overclock is still effective on the tower, upgrade it. You'll notice it will not shoot hypersonic, but just shoot at normal speed without Overclock. This also works with M.I.B call to arms. However the hypersonic speed is another glitch and will only be achived sometimes.

Maximum Enhancements Bug

• Sometimes, on the special mission The Crucible, if you try to use Overclock on a tower in a socket of power, Overclock will have no effect on the tower's speed at all. Also works with M.I.B call to arms.

Bloonchipper Bug

• Sometimes, the Bloonchipper pops all layers of bloons in one shred.

Rank 53 Profile Wipe Bug

• Sometimes, at Rank 53, it will wipe your profile of the game off the computer. 

Locked Upgrades

• Sometimes, when the bannana farm tier four upgrades are unlocked, on some games, the game says how you have not unlocked this upgrade yet. This glitch is actually intentional. It happens if either you're not the rank but you have unlocked it with XP or you're the rank but you haven't unlocked it with xp. It can happen with any tower.

Excuse me, not to be rude, but your gun is firing the wrong way.

Bloon Area Is Blind Glitch

• Sometimes, if you have a dartling gun upgraded to Bloon Area Denial System and no bloons incoming, the gun will fire straight up, no matter where you aim it. Weirdly, this does not work with Hydra Rocket Pods. Rockets can still pop bloons when this way. Aims normally when bloons come. On Sandbox mode in BTD5D, the gun will fire this way when you haven't sent bloons and none are onscreen.

BTD5 iOS

Piercing Bombs Bug

• On version 2.0 and below, when you had a Monkey Fort in the range of anything that wielded explosives, the explosives would pierce the bloons (So it looks like it pops 2 layers). This was fixed on version 2.1 (I think), but only fixed for Bomb Towers.

Monkey Money bug

• In BTD5 iPhone/iPod Touch/HD, the player can get infinite monkey money by changing the day of their mobile device ahead by 1 and opening the treasure chest. This also happens in PC versions. Though, repeating this may not be recommended as it may not be a bit functional after a few "days".
• After this bug has been exploited, the chest stops working until it is actually the day after the "day" the chest was last opened.

Treasure Chest bug

• In the mobile versions of BTD5, the Treasure Chest will give the player Monkey Money, but it is not multiplied. However, this may be intentional (if you do the math).
  • The days in a row counter will never go up also.

Sentry Bug

• Sometimes, in No Escape, the Monkey Engineer's sentries point one way but fire nails somewhere else.

Road Spikes Bug (minor)

• When spamming road spikes in BTD5 iOS, and the player ends up with less than $30, the player can buy their last pile of Road Spikes for less than $30.

Hole by Selling bug

• In mobile versions of BTD5, and in the Protect Monkey Town special mission, it is possible to sell the Monkey Town for $0, leaving a hole in the middle. The player still loses lives if bloons will go in the hole. The same goes for the Wizard Lord, and if this happens, the player automatically loses when a tower needs to be sacrificed.

Super Monkey Spike-O-Pult

• (Only works in BTD5 iOS) If the player activates the Super Monkey Fan Club ability, it will affect Juggernauts and Spike-O-Pults as well, but they will only shoot darts. Oddly, they also shoot Spiked Balls/Juggernaut Balls at ordinary fire rate.

Performance drop

• When there are fireworks (after the player completes a track), going into Freeplay Mode will cause significant performance drops.

Sextuplet Darts

• When a/there are Dart Monkey(s) (is) under the effect of Super Monkey Fan Club, it simultaneously throws darts at a hypersonic rate and it also throws Triple Darts.

Wacko sentry bug

• Sometimes when a 1-0 monkey engineer is placed near the track/ edge where you cannot place towers, the sentry is spawned on the track/edge

Banana farmer out of control bug

• Sometimes when a bloon trap is in the range of the banana farmer, the bloon trap will fly towards the banana farmer. However, you only get $40/$60/$400/$600, not the bloon trap cash.

Noob Engineer bug

• If you upgrade a monkey engineer to 0-4, then upgrade it to 1-4, the engineer's appearence and thumbnail look like a 0-0 engineer. It still has its normal functions, and this can be fixed once you upgrade it to 2-4.

Spike Factory Glitch

• Sometimes, the Spike Factory won't place spikes on the track. However, if the Bloons touch them, they will still pop.
• Other times,it will produce spikes between rounds(happens when round ends as the spike factory is producing Spikes when theRound ends.)

Banana Farm Glitch

• If a 3/x banana farm is upgraded to 4/x AFTER the round starts, you will get 13 boxes of bananas. In later rounds, you can sell the banana farm, redo this glitch, and gradually gain money.

BTD Battles

I really remember him putting MOAB asasains on his temple... Am I losing my marbles?

Temple Bug

• When an opponent has a temple of the monkey god, the game will only show the temple using its orignial sun rays, without any sacrifices. This causes lots of lag. 

Time Slow Bug

• When playing a game, time will appear to move extremely slowly. This is because of a bad processor or low internet connection stability.

Energy Bug

• Most of the time when the player gets energy in Bloons TD Battles, there is "Negative Time", where time goes negatively and the player never gets energy until the player reloads the page.

Harmless Towers

• Some Towers will not shoot with it's weapons sometimes. This happens commonly with Glue Hose, Turbo Charge and very oftenly with Glaive Thrower/Ricochet/Lord and Mortar Tower with Rapid Reload in BTD Battles. It is unknown why this happens.

Purchasing Bug

• When a player purchases something from the shop the game will crash, the medallions will be taken and the tower or upgrade will not be given.

Monkey Ace flying away bug 

• Sometimes when a Monkey ace is brought it will fly off the screen and in to the opponents  screen, and It will not be able to pop any bloons untill it gets back on your screen.

Disconnection bug

• Rarely, on Defense mode on BTDB HD, if the internet disconnects, it won't throw you out of the game. Instead, no bloons appear, but you can still gain/take benefit of Income. The game will throw you out when you place down spikes.

Hypersonic Spike-O-Pult Glitch

• To accomplish this glitch, the player needs a 2,0 Dart Monkey and a 0,4 Dart Monkey. Then, the player should activate the Super Monkey Fan Club Ability and upgrade the 2,0 Dart Monkey into a Spike-o-Pult, but it is only hypersonic for 10 seconds. This also works on Juggernaut as well, allowing the player to easily obliterate ceramics and MOAB-class Bloons.

Closing error

• When the app opens, it shows the loading screen, quickly followed by the ninja kiwi screen and then closes completely, unable to play and when double pressed the home button on iPad, the apps thumbnail is of the menu screen and when pressed it too force closes. It is unknown why this occurs.

Corrupted Matching System bug

• Since April 17, 2014, the player may only battle opponents that have a similar battle score to the player's (must not have a 10000+ difference). This sometimes occurs and sometimes not. NK confirmed that this wasn't done intentionally, but it's unknown why this happens.

Bloons Super Monkey

Invisible Sun God bug

• A glitch occasionally occurs with the Sun God: its head will become completely invisible/transparent.

Bloons Super Monkey 2

Red Blop Counter Bug

• The player can get 100% Red Blops even though there are still Red Blops in a level. Only known to exist in level 3-5, due to the amount of bloons there.

Join The Club Earlier Bug

• The player can get the achievement "100% Club" if the sum of every level played's Red Blops collected % is equal to 500%.
• If you do the math, however, 500% divided by 5 levels is precisely 100% red blops collected in a level, so of course you would get the achievement.

Upgrades lost glitch

• When the player closes BSM2, then log back in again, the player may lose all the upgrades the player has purchased. Refreshing the game will make the upgrades re-appear.

Mirrored Boss glitch

An example of the third boss glitch in BSM2. To much calamari for me!

• Sometimes in the last level (3-5) in Deep Bloon Sea in Bloons Super Monkey 2, the boss will glitch and it will display a mirrored boss in the upper corner while the real boss might come down all the way to the end, making the player lose the level.
  • Sometimes, Heavy Metal Bloon bugs out and also gets cloned. pic

Ninja Kiwi flashing lock bug

• Occasionally, BSM2 will give the player the message "play now on Ninja Kiwi" when the player plays the game on Ninja Kiwi. This only happens when the player is attempting to log in.

Third Boss Glitch 2 (aka No Boss Glitch)

• When bronze is obtained near the end of 3-5, the boss will not appear and the player completes the stage.

Upgrades Not Bought Before bug

• This seems to be the opposite of the Upgrades Lost glitch. When starting the game at Stage 1-1, a player by the name, Ninjakiwimine2 experienced a glitch that he has Fire Wave upgrade for Left Arm (Magic Upgrade 3), even though he hadn't bought it. This glitch is also possible when Intense Magic and Fireball upgrades aren't bought.

Black blob of Fire Glitch

• Hardware
• Software

1/2

• On Software mode, Elemental Strike will look like a big black blob with a flame in the middle. When this happens, switching to Hardware mode will cause the game to turn into the background color of the zone.

Super Monkey still has the Golden Bloon/Power-Up Bloon's Power-up when the player quits a Level Glitch

• When the player quits a Level while the Super Monkey still has a power from a popped Golden Bloon or a Power-up Bloon, and when the player goes to the Upgrade Menu, Super Monkey still has that power.
  Example: Pop the Golden Bloon or the Power-up Bloon on the Fourth Stage of Monkey Lane and collect the Power-up (i.e.: The Wizard Lord Power-up). Quit the Level and view the Upgrades Menu. Super Monkey still looks like the Wizard Lord, even though the player quits the Level.

Not so real Glitch

• When the player gets armored on any stage, they will beat without mouse earned blops. They will not be the real number of last. It will be random.

Bloons Monkey City

Game pausing

• Also works in BTD5.
• When you buy a 4/0 ninja monkey he will pop bloons IN SLOW FORWARD motion when shuriken is still popping.

Double Fire Glitch

• If upgrading a tower when it is doing the pre-firing animation, it will have its attack interrupted, and will instead fire two upgraded shots afterwards.

Ninja Seeking Bug

• Ninja monkeys with the Seek upgrade can/will only target the closest bloon, regardless of targeting preference.  If another bloon passes them, they will face the first bloon, and then throw towards the nearest. The Shuriken SHOULD target the bloon the monkey is facing, and then bounce TO the nearest, but it does not.

Damaged Unbuilt Tower Bug

• If a building is in construction, and then your buildings are damaged in an MvM attack, sometimes the in-construction tower will get damaged.
• If this happens, the damage time is added to the construction time. But sometimes, the timer will stop permanently, and the building can only be finished with bloonstones.

Upgrade Bug

• If you have an upgrade building in research progress, you can still access it by clicking another research building and selecting the other building from it. Most likely intentional.

Building Disappeared Bug

• Extremely rare, but sometimes you can place a building on one of four super monkey villa spaces. If you move the villa, the building will either disappear or you cant put the villa in its original spot. Also, when moving the villa, the tile where the building dissapeared will have a green-striped pattern. The building will reapear when the player moves the villa off of the spot and reloads the game.

Defended Attack Bug

• Sometimes when a player defends your attack in Monkey vs. Monkey, the message continues to pop up, and you lose honor every time it does. This causes your honor to eventually reach 0. However, this is fixed by reloading the game.

Repeated Winning Bug

• When you win a raid, it keeps poping up that your won the raid and gives you free cash, honor, and possibly achievements. The honor will go back to normal after reloading the page but the cash doesn't disappear. Also, in your battle log, it might show 10/7 raids won or more raids won than raids done.

Black Bloon Sharp Shuriken Bug (Very Minor)

• Sometimes a discoloration of the bloons in the Sharp Shuriken upgrade for the Ninja Monkey will occur. 

  

  Notice the bloons are black (should be red).

  This will cause them to be black instead of red. <lol

Patched

An example of the Tower Bug. Doing the dirty work.

Angry Squirrel Glitch

• Even when bloons haven't leaked, angry squirrel will be berserk permanently.

Challenge Saving Bug (Minor)

• It is possible to save in Challenges, however, it's only before the player starts the first round, which is rather useless.

More than max glitch

• In the July 18th 2012 challenge, if the player has reached the limit of one tower type, and sell a different one, the player can buy another one of that one, but once the player buys it, it will be locked again.

Bad Aim Bug

• Sometimes towers will attack to the left away from the bloons and still pop them in BTD5. This happens frequently with fast firing towers, such as Plasma Blasts.

Missing Menu Bug

• On the intro screen in BTD5, right click, then click on the play button. The play button screen will still be there, yet, if the player clicks where any of the menus would be (e.g.: special agents), that menu will be opened.

Life Bug

Look at the black arrow. You are now immortal and stuck on the track for all eternity! mwahahahaha!

• This bug can happen on almost everything the player does on BTD5. The first cases of it happened on the March 11, 2012 Daily Challenge, and the Wizard Lord Special Mission. The glitch is when the player loses all of their lives, the Game Over screen will not appear and the player can still play. However, the player's towers cannot attack and there will be no "Go button" as if the player had lost.

10 Bug

• This rarely occurs, once the player loads a save game with a Portable Lake with Monkey Buccaneers on top of it, it will show the number ten with a hour glass next to it, as if the player is on the special mission, Short-Lived.

Alarm Bug

• If The player clicks the quit button, run out of lives, then click yes, an alarm will sound until the player plays, where the player gets a Game Over. This also happens in the Wizard Lord special mission when the player runs out of towers, except there is no escape from it other than closing their browser.

Track 2 Bug

• If the player plays a beginner track on BTD4 and save, and when the player goes to the expansion, it will take the player to track 2 although Ninja Kiwi seems to know this as when the player does this there is a message saying that the save is from the original game and results may be unexpected.

Bug when logging into the game

I AM ON NINJA KIWI YOU DUMB GAME!

• The game has a system where the player can only play right into Ninja Kiwi. But in an update, double monkey money, the game itself did not identify the site of origin. Even if the player is on Ninja Kiwi, it gives the message "play now on Ninja Kiwi".

Castle Bug

• In BTD5, there's a rare bug; when the player completes Castle on Hard, the player doesn't get their monkey money.

Special Abilities Bug

Special Abilities Glitch. I have abilities that I can't use. this sucks

• When a tower with an ability is sacrificed to a temple, the ability will stay, though it is supposed to disappear. The ability can't be used.

Description bug

• Bug 1: In the MOAB Madness special mission, after winning the challenge, a comment will appear (it says Easy peasy.), which is the default comment for Round 2, and that's ironic, because there is no Round 2 in the MOAB Madness special mission. However, an update made no pre-round messages appearing (even if tips are turned on) in Daily Challenges, nor Special Missions.
• Bug 2: When opening a Daily Challenge (or Special Mission), when starting the challenge or mission, the default comment for round 1 (the welcome message) appears instead of the description of the challenge or mission. This was fixed on April 2, 2013.

Hotkey Abuse Bug

• This is a glitch which is similar to the tower placement glitch except the player can use the hotkey of a locked tower.

Money Losing bug

• In BTD5, when the player presses the hotkey (, for the left path and . for the right path) for upgrading on a path where there is an upgrade locked, the player will lose money (the cost of the upgrade) for nothing and the tower will not be upgraded. It will also increase the selling price. Fixed in Feb 20, 2013.

Saving bug

• This bug seems to be a variant of Deflation Saving bug.
  When the player tries to play a Daily Challenge or a Special Mission, the game will take the player to the previously saved game instead of the challenge or mission. This was fixed on April 2, 2013.

Giant Lock Bug

• After the Double Monkey Money update in December 19, 2012, before starting BTD5, a giant lock flashing purple and green will appear, and in a second, the player starts the game quicker than usual. This bug was fixed in January 8, 2013, right when the Double Monkey Money event ended. This may be a holiday surprise for the players.

Upgrade Bug

• The upgrade bug only works on BTD4.
  The bug can only be achieved with very fast reflexes. First, place two towers of the same type near each other. Upgrade one to the maximum (it can be level 3 if the player hasn't unlocked the level 4 variant). Once upgraded to the maximum level, quickly click on the other tower. The tower will then have the third or last upgrade of the tower, allowing the player to save a large amount of money, although it will only gain the trait(s) of the bought upgrade.

0 after buying Special Agents

• When the player buys more than 1 special agent a time, the player loses all of their monkey money, and the player will not get the agent. The player gets back the Monkey Money only when earning them by completing a game.

Hydra Rocket Pods Bug

• The 2/3 Dartling Gun shots don't explode, but just pierce through bloons.

Opening Title SFX Bug

• There was a bug in which the sound effects in the opening title wouldn't play. This was fixed on Thursday, June 14, 2012. In the selfsame update, Specialty Buildings were added.

Premium Bug

• This is a glitch where if the player left clicks at the edge of the premium upgrade, the player will activate the upgrade for free. This glitch was patched 2 weeks after the release of the game.

Pro Tribal Turtle Bug

• Tribal Turtle Pros cannot be placed on water.

M.O.A.B. and B.F.B. Mortar Tower Glitch

• In version 3.2 for Bloons TD 4 iPod/iPhone, the Mortar Tower could kill M.O.A.B.s and B.F.B.s in one shot, making it very easy to beat all 250 Rounds. It does not effect the damage on any other bloon, despite this. Fixed in version 3.2.1.

Monkey Glue Bug

• In BTD4, the player can place Monkey Glue off the track. It is often around the borders.

Save Bug

• (Only works in BTD5) Complete a difficulty and then click on the save button really rapidly before the message says "Congrats! You beat this track on _____!". Then when it has saved, the player must exit out then load it again. Once the player passed this level, the player can save in Freeplay Mode.

Tower Sell Bug

• When the player sells a tower, it doesn't go away, and it just gives the player money. This occurs when a player opens their BTD4 save file when playing BTD4 Expansion (whether or not this is for the first time isn't confirmed).

Track Jump Glitch

• In BTD5, Bloontonium Lab, Snake River, and Mount Magma suffer a glitch which causes bloons to skip parts of the track. Click here to find out more.

Challenge Bug

• After playing a challenge in BTD4 (such as the one to defeat 50 M.O.A.B.s in one round), placed some towers but didn't yet start the game before quitting, and then when the player goes on it again and click "Load Game", the player will get a lot of money, and the towers the player placed.

Treasure Chest Glitch

The Treasure Chest Glitch

• When the player has already opened the Treasure Chest in BTD5, it will be open and have a small 999 in it. When the player clicks, it will still give Monkey Money. However, then the player can't get Monkey Money the next day. This is not completely a glitch, as this does occur at the time it is meant to happen.

Black Screen Bug

• In BTD Battles, if the player loses, their screen will turn black after the player has won a new battle.

News Table Bug

The News Table Bug

• Sometimes, when the player enters BTD5, the News Table is bugged, and the player can't view any news, or the BTD5 mobile table. It is unknown why that happens.

Automatic Chest bug

• Sometimes the Treasure Chest gets opened without clicking, and the Monkey Money will not get deducted, and the days in a row streak will still count.

Banana Farm On Deflation Bug

• It is possible to get a Banana Farm by clicking on the very edge of the button of the tower. It also gives the player money. However, this was patched and it is no longer possible.
  • Something similar could be done with the Monkey Engineer via the Bloon Trap upgrade on Bloons TD 5 iOS. However, this was also patched.

Volume Bug

• In version 1.2 of Bloons Tower Defense 5 iOS, the music gets noticeably quieter after the player resets the track.

Stupid Mortar Glitch

Those pesky mortars... I think they need glasses with lense as thick as a Z.O.M.G.

• Those pesky mortars can't aim right: When the player targets an area in BTD Battles, the mortar aims somewhere else, although the shells still explode at the target.

Disconnection Bug

• After you and your opponent choose towers on Bloons Tower Defense Battles iOS, the player see waiting on opponent screen. While the other one is now playing round 1. After Round 1, the game isn't starting Round 2. The player who first play Round 1 will get infinite money in several seconds until a player get bored.
• For short, This Bug can't continue Round 2 but still give you $250, the income.

  

  Get ready, Wait and win! Piece a cake.

Banana Farm Flash Crash bug

• In Bloons TD Battles, when Banana Farms are used (even if upgraded to Monkey Banks), a flash crash is likely to occur in a part of the game. There's no specific round where this happens - it's completely casual. It's unknown when this glitch started to occur - first reports of this bug were in October 24, 2013 and the bug was patched on January 14, 2014.

Unnecessary Lag bug

• Neva-Miss Targeting causes lag for no reason when it starts to shoot.

Bullet/Slo-Mo Matrix speed bug

• In Bloons TD Battles, as of October 14, 2013, there are codes for an anti-hack system, which never got implemented. These codes cause lag for no reason in at least 20-40% of the games. The lag can cause the game to be slower from 1.5x slower to 8x slower. Sometimes the lag starts only in late rounds, but it's much worse than the normal lag. Computers' speed seem to affect this. Example of unnecessary lag here.

Earlier is Later bug

• • In the February 23, 2013 challenge (I Spy with My Eye), the description says the challenge ends at round 70, but when the player starts the challenge, it says 85. It is changed when the player reaches round 2. It will also happen with other challenges.

Round/Sanbox Mode

• In Bloons TD Battles, there was a bug that activated when tying in the code.
• Towers Placeable Everywhere

Bloons Tower Defence 4 Glitch

How to Place towers any place you want... Even on the track

If the player hovers their cursor over a spot where the player can place a tower when the player has a tower selected, and right click on that spot, and then while the right-click menu is shown, click anywhere and the player can place that tower anywhere. (Patched in v1.18 exp)
