When you select a tower, then exit the track, and then open it up again, you'll see the tower info at the bottom.
When this happens, it is possible to do the 4/4 Tower Upgrade Glitch.
Wait, there's no Ice Monkeys here! Why the tower info?
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 (now patched).
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 ability can also be used when there are more than 1 of the ability. This is best result with Supply Drop Sniper Monkeys, where player may receive much more money. Best used with auto-clicker on co-op match, where both computers and internet connection between slows down game significantly.
Its best to do while activating the Super Monkey Fanclub Ability and having MOABs getting destroyed so the Lag is increased.
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.
Abilities already on cooldown seem to be unaffected.
Double Fire Glitch[]
If a tower is upgraded when it is doing the pre-firing animation, it will have its attack interrupted, and will instead fire two upgraded shots afterwards.
Can Not Place Towers Bug[]
Sometimes, when you place road spikes or pineapples in large amounts with a clicking macro, you cannot place any more towers.
This can also occur with prolonged periods of lag, such as in late freeplay (tested in high quality).
Dart Monkey[]
The Hypersonic Fail Glitch. Wait, Super Monkeys don't fire Juggernaut balls!
Hypersonic Fail Glitch[]
On mobile, Hypersonic Spike-O-Pult Glitch doesn't work, and instead you get a Super Monkey that shoots a Spiked Ball at the normal rate. Also, 3/x or 4/x Dart Monkeys can be transformed to a Super Monkey that shoots a Spiked Ball.
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
Blindfolded Dart Monkey[]
Sometimes,the 1/2 Dart monkey would throw darts away from the target.
I almost feel sorry for that MOAB.
Hyper-sonic Catapult 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 hyper-sonic for 10 seconds. This also works on Juggernaut as well, allowing the player to easily obliterate ceramics and MOAB-class Bloons. This is known as "Super Juggernaut Fan Club" by fans, and fans call it an easter egg, though some calls it a hack.
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.
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.
Wait, the people at Ninja Kiwi promised me red stuff! SO WHERE'S MY RED STUFF?! :(
Ninja Monkey[]
Ninja Always Seeking Bug[]
Sometimes, an x-0 Ninja's shurikens will seek anyways, even though you haven't upgraded him to do that. Cannot send his shurikens 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.
Shadow Double glitch 1[]
A ninja's shadow double's range will stay if it disappears while clicked on.
Bomb Tower[]
Bomb on frozen black bloons bug[]
When a bomb tower's bomb hits a frozen black it makes the sound of a sharp object hitting a frozen bloon along with the explosion. Also the explosion has no effect on nearby bloons.
Melee MOAB Assassin bug[]
Bug 1: Sometimes a MOAB assassin will instantly kill a MOAB-class bloon with its normal shooting attack when you haven't used the ability. For example, a MOAB assassin is attacking bloons when a MOAB comes. You don't click the ability, but when the tower launches the missile like normal, the missile will kill the MOAB in 1 hit. Like the ability, it does 753 damage to ZOMGs with this bug.
Bug 2: This is a rarer bug 1. If you have a MOAB assassin 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 assassin again, the tower won't kill the MOAB but just do x10 damage to it like an MOAB mauler.
MOAB Mauler misfiring bug[]
The bloons are hypnotising my towers!
These Super Monkeys are useless...
When a bloon is popped just before a MOAB Mauler was about to shoot at it, the Mauler will instead shoot directly to the left.
This may work on other Bomb Tower upgrades as well.
Glue Gunner[]
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 Buccaneer[]
Outstripped Glitch[]
An ill-placed x/3 Buccaneer will miss most bloons (including reds) completely and therefore cause leakage. Although this happens with other towers (even Super Monkeys), x/3 Buccaneers placed a little bit away from a large bend in the track suffers the most.
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 an 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.
If the MOAB Takedown Ability is used and there is a Ceramic bloon, MOAB, or a BFB on the screen but it is already partially damaged so there are cracks and rips in it, once the hook begins to drag the Ceramic, MOAB, or BFB in, the cracks and rips will disappear, as if the bloon/blimp has regenerated itself back to full health. This glitch happens every time, and if it is intended is unknown.
Monkey Pirates of the Caribbean V: Monkey Pirates Glitch. Coming soon to a theater near you! Rated G for glitch.
Monkey Ace[]
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'sSupply Drop Ability.
Play one of the tracks until you get a temple. Save, then quit the game. The next time you play, the temple will sometimes be on a weird angle.
Seems legit.
Temple Outline bug[]
Similar to Temple on weird angle, but this time if you place the temple and look at its white outline, it will be on a different angle to the temple. (the default one)
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, its eyes will be blinking as if it is still firing. This bug was removed but it came back when three new tracks (Fireworks, Tunnels, and Country Road) were added. This bug can be fixed by placing a Monkey Village next to the Temple of the Monkey God.
Very rarely, when you sell the Temple of the Monkey god right after you purchase it, the animation will show and you cannot tap on it. Then, the tower will simply dissapear. It is unknown what causes this
Monkey Village[]
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 Boomerang 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).
Placing a Monkey Village near a Bloonberry Bush will unintentionally reset the amount of spikes it has.
Ghost Village Bug[]
Placing 2 Monkey Villages next to each other, then getting Monkey Beacon on both villages allows a village to remain discounted and have a large range after the other village is sold. WARNING: it fixes itself whenever you reload a save.
Rarely, (usually when a ZOMG is spawned) a Ray Of Doom will appear where the beam was firing when you move it.The beam is a ghost and will not damage bloons.This glitch can be fixed when you exit the map.
Invisible Death Beam Glitch[]
In some games (usually on Sandbox Mode), if an MOAB appears right after all bloons on screen have been popped, the Ray of Doom will become invisible.
Excuse me, not to be rude, but your gun is somehow 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 BTD5, the gun will fire this way when you haven't sent bloons and none are onscreen.
Monkey Apprentice[]
Lag Bolt Bug[]
Sometimes the lightning will travel to the edges of the map and temporarily drops the frame rate drastically. This is most common when playing the Random Mission "Ride the Lightning: Part Deux".
Other[]
Svg Bugs[]
Some towers image are bugged like the monkey apprentice 1-0
Monkey Apprentice, are you okay?
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.
Hypersonic Tower Exploit[]
If you use Call to Arms or Overclock to a 0/x Tack Shooter, then upgrade it to 2/x, the tacks/blades will shoot at a hyper-sonic speed, much like the one in BTD1/2. This also works with the Bomb Tower, Mortar Tower, Monkey Buccaneer, Dartling Gun, Sniper Monkey, and Ninja Monkey.
Anger Issues Glitch[]
Rarely happens, even when bloons haven't leaked, angry squirrel will be end up berserking permanently. This happens during rounds on random occasions.
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.
Disappearing Towers Bug[]
Sometimes when you zoom out the screen, some towers or part of them will disappear. They will appear when you move your mouse over them or when you drag a tower near them( without placing them). Sometimes they will also appear or disappear suddenly in the middle of a round when they are shooting at bloons. They will still shoot when they are invisible but sometimes the projectiles will be of bad quality or resolution. There is sometimes an invisible square around the bloons and only the projectiles in the square will be of high resolution. The invisible towers will also appear in this square until the square moves away. This usually happens on older browsers such as old versions of Internet Explorer. This usually does not work on some towers such as tack shooters but is more common on some towers like super monkeys or apprentices.This can be fixed by setting the zoom to 100%.
Hypersonic Ballistic Missile bug[]
It is EXTREMELY rare, but sometimes the Monkey Sub will fire and reload missiles at hypersonic speeds, which can easily destroy ceramics and MOAB class bloons.
Gameplay[]
Co-Op Mode[]
No Continues in Freeplay Mode
Sometimes after beating any track and selecting "Continue in Freeplay Mode", the game will start the next round but after popping all bloons for the round the round does not end, only continues without any new bloons or round progression.
Fast-Forward Bug[]
On old or slow computers, the screen freezes when you turn off fast-forward gameplay goes back to normal when you activate fast-forward again.
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. This only happens when the player is on the right side.
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 or blacking out the game (but not the border including Towers, Agents, etc.), but it doesn't work. Sometimes they don't count as leaks, but most of the time they do, resulting to a loss of lives or game, depending on what bloons leak. This bug makes it very difficult to win a co-op track on hard.
Special Missions/Tracks[]
Shadow Double Glitch 2[]
In Daily Challenges, if there is a maximum total tower limit, and you try to place another tower while having a shadow double active and there are still less than the total, the game won't let you place any more towers. This is fixed by selling another tower.
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.
Is the track... a piece of wood?
North Pole track bug[]
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.
Blank Screen Bug[]
On rare occasions when clicking on a track, a white screen will show and you will have to refresh the page.
Endless Fast Upgrades Bug
In the "Fast upgrades" Special mission, Once round 5 has ended, your turrets can stop firing but the round itself will not end, meaning you cannot win.
This is particularly likely if you get a temple (upgraded from a free Super Monkey placed on round 1) and it sacrifices a tower.
White flashing screen bug.
Flashing screen on co-op mode for seemingly no reason. Happened after round 65 I believe, on medium difficulty on Z track. Goes completely white when pressing fast forward, but can still access towers and upgrade them. Only happened to one player, after game ended every thing was normal and not glitching. Had to simply put up with it until we finished the private match.
Other[]
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, in an update, the RBE of the round does not change; it stays at 24 (or some other random number if on fast track) independently from the round the player is playing.
Invisible 4/4 Tower bug[]
Invisible Force Fields
There's more than just dart monkeys waiting for some bloons to pop. Watch out for supernatural forces during your game.
If the player places a tower, hits backspace or delete, and clicks on the spot where the tower was without moving their cursor at all, an upgrades bar for the sold tower will appear at the bottom. It will have no Official Artwork. The player upgrade it to 4/4 (if it remains 3/1 or 1/3 and the player buys the less upgraded path first).
This bug used to give you invisible abilities, however that is no longer possible, ever since the Monkey Sub update. It still deducts money though, making it practically useless.
Menus and Buttons[]
Go Button Glitch[]
Can't I take a break from popping bloons for once!
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.
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.
Glitchy Chest Bug[]
Sometimes, the player can't click on the Monkey Money chest. Refreshing the game helps. Sometimes though it will tell you to wait until the next day to try again, thus also losing your day in a row streak.
An example of the Achievement glitch. Is this some fancy new Pig Latin?
Main Menu Bug[]
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.
No, this is not what Absolute Zero looks like.
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[]
Sometimes, when the player taps on a achievement and wait, it will become invisible, but some letters of it will remain.
White Screen Of Death[]
Dart Monkey, that's not a bloon... OR banana.
Sometimes, with a bad connection, and when the player loads BTD5, it loads like normal, but the player logs in as a guest (or on rarer occasions, as a user). 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.
The round 12345678 is very-very-very-very-very impossible to reach. since there's no way to reach it other than this bug.
Also, you have 1234567 money and 12345 lives from this bug.
These are most likely placeholders.
This can be fixed by using the "Ground Zero" ability of the monkey aces.
Grey Unlock Glitch[]
If you unlock a tower in a mission where you can't use it, the picture will still be grayed-out as if it were locked. This can only happen in BTD5 Mobile, as on Flash, Daily Challenges are unlocked at Rank 19, the same rank where the Spike Factory and Monkey Sub are unlocked.
Crash your Chest[]
If you open the game and click the chest, sometimes your Flash player will crash at the precise moment that the monkey money is about to be added to your stash. If you reload, it will say you already opened the chest but you won't get the monkey money. This is not a very common glitch.
Infinitely Falling Monkey[]
When you first pull the game up and the play button pops out of the ground, if you click it at a specific moment as the monkey is falling onto the 'Bloons TD 5' text, the sound effect of the monkey falling will play over and over again. This sound continues even if you start playing a track. It can be only fixed by reloading the page.
