Current Bugs[]
Money draining glitch[]
In the challenge browser, if you create a challenge on round 59 and lose on round 60, then try to restart on round 60, it will take away monkey money. (can someone please look into this, I lost a lot of money).
Can't Afford an Affordable Upgrade[]
Sometimes in Contested Territory a tower's most expensive visible upgrade is greyed out and cannot be bought if you cannot afford the combined total of all the visible upgrades. When the upgrade is bought under this state only that upgrade is bought and the normal amount of money is used.
Sometimes in Contested Territory a tower's second most expensive visible upgrade is greyed out and cannot be bought if you cannot afford both it and the cheapest upgrade. When the upgrade is bought under this state only that upgrade is bought and the normal amount of money is used.
Invisible Geraldo[]
Sometimes if you try to place Geraldo at the top platform of the map Quarry, his model will disappear except the items on his back.
Lost Map But Didn't Play[]
- Once the player loses all their lives and quickly presses the options and then the home button, the next game the player plays will have the game over screen.
7/8 Crash[]
- On some devices, the game will crash right after "7/8 Progress" is shown.
Removable Obstacles are Bugged[]
- If the player plays a map with removable obstacles, remove it, and then save afterwards, the obstacles might not be removed.
- Likewise, sometimes unremoved obstacles save as removed.
- Rarely, removable obstacles are disregarded and monkeys can shoot through them.
Invincible Ceramic Bloon Oversight[]
- Sometimes, Ceramic Bloons spawning from MOABs are immune to thorns from the x/5/x Druid. This only seems to happen with ceramics spawned by MOABs. Possibly intentional, but unlikely.
Pirate Lord/Monkey Pirate Glitch featuring Cripple Moab[]
It looks like the ZOMG has headed into the infinite abyss.
When using the Pirate Lord's ability, or the Monkey Pirates upgrade with a Cripple MOAB with Even Faster Firing, the M.O.A.B. Class Bloon is being stunned while the grappling hook is trying to pull it. The results are a hook that is phasing through reality or it will disappear. If all towers are sold, the M.O.A.B. Class Bloon will be pulled like in the glitch for Bloons TD 5.
Infinite Spike Storm[]
- This glitch will cause the fifth tier middle path spike factory to endlessly spew out spikes.
- Buy the 0/5/0 Spike factory
- Put the speed to slow (optional, but makes the timing easier) and when the next round starts and it starts spreading spikes, buy it into a 2/5/0 or a 0/5/2
- It should now be spamming spikes everywhere! (Recommended to sell the factory after a while, otherwise the game may crash.
Eternal Wrath[]
Wait, so this is the True Sun God?
- This glitch is done using the Avatar of Wrath.
- If you upgrade it to 1/0/5 or 0/1/5, the wrath particles will stop changing and a second set of wrath particles will appear. Upgrading it again will create a third set of wrath particles. If you sell the tower after this, you can see that one set of wrath particles is permanent.
- This can be done an infinite amount of times, just make sure the Avatar of Wrath is a 0/0/5 Druid so the glitch can be performed.
"Time Rewind"[]
- In Co-op mode there is a chance for the game to "Rewind" time by a second or two after a round, in regular speed.
- The bug cancels all upgrades done a bit before the rewind and refunds the money used for the upgrades.
Flagship Vision Glitch[]
- If towers on top are moved via a Support Chinook, they will retain their ability to shoot over walls, despite being on ground level.
Start Twice[]
Btd6 Title and load screen bug
This video shows the "Start Twice" and "Downloading..." bug
When the player clicks/taps the screen when the title is appearing as part of the beginning animation, the title will pop up twice.
Downloading...[]
Whenever the player starts the game after downloading an update, every time the game is opened afterward the load screen will display the downloading bar (this happens on mobile and possibly the PC version)
Necromancer: Unpopped Armies[]
Whether or not it was intentional, X-X-4/5 Wizard Monkeys are able to summon extra Undead Bloons if only a few Bloons are popped (ex. 3 Necromancers will summon 3 Undead Bloons for 1 Red Bloon).
Sub Glitch[]
The 3-0-0 sub and 4-0-0 sub
On the map "Spice Islands," placing a sub in a certain spot and upgrading it to 3-0-0 will cause it to have the "submerged" option and the radar, but it will be above water. Upgrading it further will show the sub in water, but no radar and lower in the water than usual (it will be less visible). Upgrading it one more time will cause the energizer's tall fin to be the only one sticking out of the water.
Un-Enhanced Embrittlement[]
If you upgrade an Ice Monkey to Embrittlement, purchasing the Enhanced Freeze upgrade causes a bug where the tower will not pop Black bloons or higher on their first hit - this also applies to Deep Freeze. This can be avoided by simply not buying the upgrade or by purchasing Super Brittle.
Invisible Spikes[]
If a player chooses the expert map "Dark Castle", any spikes on the bridge at the exit will be invisible. The spikes will still pop bloons that pass over.
Proof of the glitch
Sandbox rounds glitch[]
For this glitch, you need to go into sandbox mode and press the round button to set the round instead of using the set round option. You will be able to set the round to up to 7 digits instead of 4. This means that you can set the round up to 9,999,999. It is unknown if this is intentional or not.
Thanos-Snapped Phoenix[]
In version 17.0, after using the Wizard Lord Phoenix ability, the base Phoenix that usually accompanies the tower will not respawn once the ability ends. This update also corrected a bug where Wizard Lord Phoenix was mistakenly counted as two towers, so it is possible that this is related in some sense.
Darkshift Tower stacking[]
When using the Darkshift ability, and a tower is placed at the destination during the animation or before the server realizes the ability was used in co-op mode, the super monkey appears in the same place as the other tower.
No game over in co-op[]
If a player disconnects (not simply leaving, causing the game to wait for reconnection) at the precise moment you run out of lives, the game over screen won't show up. You can interact with towers, sell, upgrade, etc but the current round won't end.
Middle-Centered Towers[]
Middle-centered Inferno Ring in Infernal, with Special Poperations and Carrier Flagship sold for display purposes
Multiple Spiked Mines placed in illegal positions
It is possible to place certain tower types on the center of the map regardless of map placement. Using Special Poperations with Door Gunner plus a Carrier Flagship, activating the Door Gunner Redeploy ability onto a Carrier Flagship platforms and immediately selling the Carrier Flagship just before placement will default the Special Poperations to place the tower at the center of the map. It is possible to place towers such as Spike Factories in the center, too, even though they cannot fit on the Carrier Flagship, which can be done by placing an Arctic Wind (or higher) on top of one of the Carrier Flagship's platforms and placing the Spike Factory within one of the Arctic Wind's ice platforms. Interestingly, the Special Poperations occasionally places it next to the center, and sometimes near the end of the track (tested on Park Path with multiple spike factories), or by linking a tech bot to an engineer paragon, which would make the paragon sentries automatically default to placed in the center of the map.
No attack animation bug[]
When a tower attacks every frame or faster continuously for long enough, the tower will go to its idle animation. Most noticeable with x-x-5 Elite Defender snipers.
I don't want to be upgraded[]
There is a chance that upgrading any towers may make them revert the upgrade. This is most common with Banana Farms and Ninja Monkeys.
Inconsistent Co-Op Count[]
At the end of a co-op match when the stats for the game are presented, players are not given the same information. The data values that do not match are:
Two different devices at the end of the same game
- Pop Count
- Cash Generated
- MOABs Popped
- Pop count for Monkey Star
- Values in the accolades
Green Paragon Button[]
An image of the Glitch (With Glaive Dominus
- Getting the money required to upgrade a Paragon while the menu for said monkey is open will show a Green Button, instead of a Dark Blue one that's supposed to show. This is just a visual bug and is immediately fixed when exiting the menu for said monkey.
Cloudy Background[]
- If you enter the Content Browser, then select Oddyseys and hit Create, the transition cloudy background will stay until you exit Content Browser.
Multiple stacking pools with no footprint[]
Multiple stacking pool no footprint glitch
In Version 31.2, it was discovered that Portable Lakes can be stacked with no footprint if given enough of them. Having them stacked on top of each other about 20+ times causes all towers placed at the apex to have no footprint. Shown here is the bug.
Regrow Farming Bug via Bloonarius spawns[]
The SECRET First Place Strategy!
Demonstration of the bug in full detail
It is possible to create a Regrow Farm by an exploit related to Bloonarius Minions. To perform this, Tier 3 Elite Bloonarius must be beaten as quickly as possible, all bloons except the Bloonarius Minions must be killed before Round 80, leaving just the Camo Regrow Ceramics from the spawned DDTs. Upon going home after Round 80, the save state of the bloons would be glitched to only have the Bloonarius Minions on screen, which causes the game to think it is in the "normal" game state. The Regrow Bloons resulting do not give additional cash but can be used to create a theoretically infinite amount of cash via income ability farming without the 3-minute income ability cap per round. Naturally, attempting the bug would give a stall timer penalty, but it can be completely bypassed by going back home.
Ninja Kiwi has planned to ban players who abuse this bug on Ranked Boss Events.
Contested Territory no buying upgrade[]
The bug where upgrade cannot be bought
Under some circumstances, restarting a currently played game in Contested Territory may cause the game to not let players upgrade a tower.
Special Monkey Names[]
Requires Monkey Names to use. This glitch occurs when typing in a Monkey Name for any tower and you restricted characters, then for the few frames the character appears press enter. You can repeat it but if you fail once it will delete the previous character so long as you don’t have it saved. Can be repeated twenty times max. You might have to spam different characters to make the numbers show up.
- Adding any other character will cause the numbers to be deleted. Though using the few frames it is still their you can add on to it.
- This glitch only occurs when playing on mobile.
Chinook cannot pick up bug[]
Support Chinook interactions with its pickup ability can sometimes fail to allow another pickup due to frame-perfectly picking up a tower and selecting the to-be-grabbed tower on the same frame while simultaneously resetting abilities by any means.
An example of this bug showcased with Rejuv Potion.
Total Transformation Infinite Wrath Bug[]
Druid of Wrath when paired with a Total Tranformation with less than 200 Wrath points will keep gaining Wrath almost near-infinitely and never reset its old Wrath bonus until the game save is reloaded. The bug is inconsistent in how it performs in-game.
Players who abused this bug for Boss Events, specifically the Week 122 Lych Event, will have their leaderboard scores revoked. The event following it has since re-banned Total Transformation and Transforming Tonic.
Stacked Pools with no footprint[]
With enough stacking of Portable Lakes via Arctic Wind platforms, the towers on the very top of the portable lake will have zero footprint.
Beat the Map Twice if you Want your Medal[]
Map and profile doesn’t show or consider the game mode beaten and doesn’t reward the medal. In my friend’s case, it was Half Cash. Currently only found on mobile version, possibly due to lag
Upgrading my Teammate’s towers…or Maybe Not[]
Occasionally shows on Co-op games that you can upgrade your teammate’s towers if you have the right amount of money by lighting up the upgrade green.
But I don’t want to use my ability[]
Abilities will occasionally not activate if you click them on mobile, this may be due to a bug in the coding or simply a one-off glitch.
Loading… Forever[]
After beating a map, the game will occasionally glitch out and load forever until the player closes and reopens the game completely.
Patched[]
Regular Tower to Hero[]
- An unknown cause, but a regular tower can become a hero. Unknown which version it was patched.
The Regular Tower to Hero glitch (Sandbox).
Support Chinook Quantum Physics[]
- Normally during a game, the player cannot have two 5th tier towers or two heroes (without Master Double Cross). However there is a glitch which allows you to do all of that, as well as place towers anywhere.
- Buy a tower's 5th tier or a hero (let's say a Plasma Monkey Fan Club) and then buy a Support Chinook or two. Change your control settings to Drop and Lock.
- Activate the "move tower" ability and select the tower you want to replace. Hold your finger over the tower and do not let go. Then try to drop the tower down at the same time as you are constantly pressing the checkmark button in the top right corner. It has to be precise, and it is hard.
- Eventually, your tower will be duplicated to your tower's new position. All the clone towers still function, even abilities. You can clone a tower as many times as you want. If you cloned a hero, abilities will stack.
Cash Drop Is Broken[]
- If the player starts a round with a monkey placed, and then activates a cash drop, do not collect it when it comes down. Instead, wait a bit and the cash drop will give the player practically infinite cash. Patched in the June 20 bug patch update.
Too Many Free Dart Monkeys[]
- If the player has bought the Monkey City upgrade for the Monkey Village after round 80, the game will give the player infinite free dart monkeys. Patched in update 2.0 (?)
Gimme My Stand[]
- If a 4-0-0 Druid is moved with the support chinook, it's stand won't be moved. Similarly, if a 5-0-0 is moved, it's cloud will not move.
The glitch in action. Wait, GIMME MY STAND BACK!
Crash Chinook[]
- If you place a Wizard Lord Phoenix and move it with the Support Chinook while its ability is activated, the game will crash. Fixed as of the 3.0 Update.
- The same thing happened with the Arctic Wind in the 11.0 update, where moving the arctic wind that the Support Chinook was on would crash the game. This was fixed in the 12.0 update.
I Have Infinite Power[]
- If a 0-3/4-0 Alchemist gives anything that has an ability to target and/or attack bloons from any place on the map (i.e. Pirate Lord, Pheonix, etc.) a Berserker Brew, it shows that the tower has infinite range. It's mostly a graphical bug, but the Jungle's Bounty (x/4/x druid) ability and Primary Expertise (5/x/x village) are affected by this and can be exploited.
The round hasn't started, but there is a ZOMG at the start.
Fake MOAB-Class[]
- Sometimes a MOAB-Class Bloon pulled in by Monkey Pirates/Pirate Lord will stay on screen, even after the round has ended
- It will stay there until you re-enter the game
- It is simply a visual glitch that stays there, the worst it can do it obscure your vision.
Hesitant Spike Factory[]
Pls work!
- For some reason the Spike Factory will not shoot outside of its original range unless you have one of the special targeting options for Directed Spikes.
- Fixed in update 3.0.0.
Floating Dumbbell[]
- When Benjamin uses Bloon Trojan while in the middle of his dumbbell idle animation, the dumbbell will appear to float in midair. This is a minor graphics bug and will return to normal when the same idle animation is activated. This was patched in the 4.0 update.
What Tower is This? Bug[]
Uhh... Is it the 80 Banana Tower???
In 9.0, The Banana Farm did not have a name, occurring in most parts of the game. This was a visual glitch and did not affected gameplay. It was fixed in 9.1, now the Banana Farm has a name again.
Not Really a True Sun God Bug[]
In 9.0, If you sacrifice towers to a Sun Temple with sacrifices, once you upgrade it to a True Sun God, it would mess up the True Sun God's sacrifices, losing the already existing ones as well as adding the new sacrifices to the Sun God. For example, let's say if you have a Sun Temple with $50,000 Military Sacrifices with 2 Golden Spectres flying around it, and then do another $50,000 Military Sacrifice, when you upgrade it to a True Sun God, it would lose the existing sacrifices but gain the new ones, making it STILL have 2 Golden Spectres flying around it. This was fixed in 9.1.
Killer Dart Monkeys[]
Dart Monkeys rule!
- This glitch requires you to have unlocked Super Monkey Fan Club or Plasma Monkey Fan Club and Total Transformation.
- You can essentially use them in a combo, but it only works if you do Super/Plasma Monkey Fan Club first.
- The result is a killer squad of plasma shooting attack monsters of absolute chaos, able to easily destroy a B.A.D.
- You can throw in other stuff like Beserker Brew Alchemists and Monkey Villages for even more destructive power!
- Only works on 5 dart monkeys at a time.
- Ninja Kiwi said this "glitch" was intentional, however, this glitch was patched as of the co-op update.
Supersonic Elite Defender[]
If a player buys an Elite Defender on the expert map "Dark Castle", the Elite Defender will fire 4x as fast as usual, making it it gain thousands of pops in seconds.
I can now have more than one Hero!![]
- In update 4.0, Ninja Kiwi added a feature where you can select the Hero you want in a Daily Challenge. However, when you complete a round with that Hero, go to the main menu and select another Hero and resume the daily challenge you played and you can place a different Hero. You can have up to 6 Heroes in a map currently with this bug/exploit.
- However, having more Heroes in a single game will make them level up slower, since Hero XP is shared with all Heroes and is independent from tower XP.
Dynamic Octet!
- It was patched in the 5.0 update, but brought back in the 12.0 update and patched again in 13.0.
Super powered Temples[]
- Any buffs applied to a Sun Avatar or Sun Temple before they are upgraded are kept with the next upgrade. While this may seem intentional at first, these buffs include the Call to Arms ability, x/x/x/1 Sun Temples x/x/x/2, True Sun Gods, and 2+-X-X Alchemist buffs. Furthermore, these can be reapplied, leading to extremely powerful temples. Additionally, buffs applied to the Sun Avatar can be carried to the True Sun God and Vengeful Sun God.
- However, if the player exits out of the game, these buffs will be reset.
Multiple Paragons of the same type[]
How To Get UNLIMITED Paragons In BTD6
Video demonstration of the bug
Infinite Paragon Bug!
Spoken demonstration of the bug
- In Version 31.2, it was discovered that multiple Paragons of the same type can be placed at once. To perform this, on the same frame that the player presses the upgrade to Paragon for one tower type (i.e. three unique T5 upgrades of the same tower type, such as a Dart Monkey's Plasma Monkey Fan Club to Apex Plasma Master), quickly switch to another Tier 5 upgrade that has a Paragon upgrade (e.g. Bommerang Monkey's Glaive Lord into Glaive Dominus), and then accept the upgrade. If the game doesn't crash, multiple Paragons can be made. The T5 upgrades involved in the glitch must be of different paths, otherwise causing the game to crash. The towers must also not be fully crosspathed or the game will crash. (i.e. a 5-1-0 Dart Monkey will not crash, but a 5-2-0 will.)
- This bug was patched in Version 32.0, shortly after its discovery. Before the update was released, however, ISAB was able to beat Round 1000 on Spice Islands by abusing this glitch with Navarch of the Seas.
Mortar Monkey crash[]
When placing a Mortar Monkey and selecting where to target, the game crashes. This happens when the mortar makes its first shot before its target is selected.
Infinite Money[]
In Version 16.2, if you place a land tower on water via Arctic Wind and sell it on a map where the middle pixel is blocked (like Rake, Dark Castle, Muddy Puddles and so on, but water is not considered as obstacle, and on some of the maps the towers should be large enough to cause the glitch), the tower will be sold twice, and by doing so repeatedly you can gain infinite amounts of money, even on Deflation. This glitch was patched in version 17.0.
Losing to a Golden Bloon in Co-op C.H.I.M.P.S.
Golden Bloons counting as leaks[]
- Even though Golden Bloons don't actually make players lose lives, Version 31.2 made them do so. Leaking a Golden Bloon will make players lose lives equal to their starting HP, and even end the game in Impoppable and/or C.H.I.M.P.S. Losing to a Golden Bloon round, provided that the Golden Bloon escapes, will display a blank white square with a RBE that matches its starting HP.
- Fortunately, Ninja Kiwi had put all Golden Bloon events on hold in early May of 2022 shortly after its discovery, and thus Monkey Teams took their place until the bug was resolved on August 3, when Version 32.0 was released.
Special Poperations Marines[]
In version 17.0, when the player uses Special Poperations to move a land tower and uses the marine ability right before the tower lands, the marine will be placed down and more marines will spawn at the same place every few seconds right on it. This 'marine stack' can easily take down a lot of bloons until the player uses the ability again, and if again in this way, the glitched marines will spawn in the new spot. This glitch was patched in version 17.1.
Broken Selection Glitch[]
I'm loving this fancy new backdrop!
#SWEET!
- If you have a saved game on a track, the glitch can be performed. Select a difficulty, then a game mode, let's say Deflation. It will ask the player if you want to overwrite the player's saved game. Press the back button in the top left corner, which, for some reason, is still usable. Then press yes (to overwrite the player's saved game). It will bring the player to the track, but the menu will still be there. Pressing on one of the options and then clicking a game mode will crash the game. This is the player's only option, since the play button won't work.
- You can also press the back button again (you can do this by clicking on a difficulty it's the only button that won't crash the game), which will take the player to the track selection menu. This will cause some rather weird effects, like letting the player change your hero in the middle of the game (although the player can't place him/her).
This glitch was patched in an unknown update.
What are those guys doing there?
Liquid Crates[]
- In the map Town Center, there are two crates near the exit that water towers can be placed on. This can actually work towards the player's advantage, since the water on the map is far from the track. This was patched in update 2.0; attempting to load a save with such towers on the crates after the update will crash the game.
Always Active[]
A 5-X-X Sub may make some abilities have no cooldown, by the time their abilities finish. Fixed in version 10.0
- The Grand Saboteur's ability may have no cooldown under this effect, allowing all Bloons to permanently have less HP and speed.
- Another ability that is affected is Pat Fusty's Rallying Roar, which can make towers permanently do extra damage to MOAB-Class Bloons.
TT5 inheritance bug[]
This is a bug related to Total Transformation and was discovered in version 38.3. The "TT5 inheritance bug", or more popularly the "Entanglement Bug" or "Quantum Entanglement", is one that involves inconsistent linking between recently transformed Total Transformation mini-monsters and additional entities in the game.
Previously thought to be related to the Super Monkey Fan Club or Plasma Monkey Fan Club, further testing proved that only the Total Transformation is required to trigger the bug. When Total Transformation is used, then sold while active, and then the various transformable towers (e.g. Dart Monkeys and Ninja Monkeys) be linked upon another tower, then the transformable towers can pass on strange interactions to other newly placed towers. If a Wizard Monkey that was transformed by the Total Transformation was upgraded into a Wizard Lord Phoenix and was linked to another tower that had an active ability (such as Homeland Defense), should the latter's ability be activated while the Wizard Lord Phoenix's ability was active, that ability would be activated permanently, even bypassing the 3 minute cutoff time for all cash-generating abilities. In some interactions, a Boss Bloon can also be sold, as referenced on this post on r/btd6.
A commentary by Chom Chom also discussed more about this bug. HBomb made a commentary about the bug in a succinct way. 【BTD6】冰罕GreenKookie showcased that it was possible without the Dart Monkey, making use of a Wizard Lord Phoenix linked to an Elite Sniper to generate infinite money. Ethan Reid also made an update on the bug, showcasing that it is possible to supercharge a Vengeful True Sun God with a support Sun Temple. A video by MackanRules goes into full-depth on how the bug works exactly.
It was patched in 39.0.
Explanation of TT5 inheritance bug[]
Every tower, bloon, and special towers (specifically, the Cave Monkey in Frozen Over and the Dungeon Statue) have a property called an entity. (e.g. The airstrip and the plane of the Monkey Ace are considered one entity, with the airstrip considered the base entity but Nail Sentries produced by the Sentry Gun engineer is not an entity of the engineer due to being classified as a sub-tower). When Total Transformation is used on a valid tower, the base entity remains (e.g. if you check the Dart Monkey after it got transformed, you would still see that it says Dart Monkey), but any entity that was dependent on the base entity (e.g. attack and range) is temporarily replaced by the entities granted by the Total Transformation (in this case, the Dart Monkey no longer attacks by throwing darts, but instead, attacks with its plasma laser). Once the transformation period ends, the original entities of the tower once again replaces the Total Transformation sub-monster's entities. (e.g. so in this case once the transformation wears out, the Dart Monkey's plasma laser attack is destroyed and replaced by its original dart attack.) The end-of-transformation is also accompanied by an effect entity to visually signify the end of the transformation that last for 4 seconds. This effect entity is what the bug is targeting. When you place down a tower just after the visual entity is removed, the new tower's base entity may overwrite the visual entity, causing the game to never expire the visual entity since it is still present via the newly place tower.
As to why the timing to replace this entity is strict, it is due to the way the game handles entities via a cache. It stores these entities in a cache where it would then clear out after a while. It is when the tower is placed just as the cache is being cleared of the visual entity does the bug happen.
