Bloons Games[]

Main article: Bloons Games/Known Bugs

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).
  • This is probably caused by the fact the blimp will get destroyed by trees. However because there is no blimp, it acts like a black hole and if the monkey reaches there, he will get "sucked in" and disappear.

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).

Hot Air Bloon iOS[]

Save Scumming[]

  • Exiting the app after dying but before tapping the screen will let the player keep their lives.

Visual Glitches[]

  • After dying to a level, it will continue to generate more bloons for a few seconds visually. This even affects boss levels, and levels without normal bloons, but has no gameplay effect.
  • On rare occasions, Level 6's Boss Stage may visually appear like the monkey is in the way of damage, but does not die. This glitch is purely visual.

Invisible Wasps[]

  • Squashing a Wasp will occasionally retain their hitbox in motion, causing the player to die from something invisible.

Static final boss progress[]

  • The seventh boss stage may sometimes bug out, and not have the player, the boss, or both make progress on the progress bar until a minute passes. This can result in the player amassing unrealistic amounts of speed.
Hot_Air_Bloon_iOS_Boss_7-Monkey_Baron_Glitch

Hot Air Bloon iOS Boss 7-Monkey Baron Glitch

Bloons 2[]

Secret Zone not unlocking after beating last level[]

  • After passing the last level of a zone with either unlimited darts or a Super Monkey, the levels in the next zone can be played but not after quitting the level and trying to re-entering that zone again. Then the player cannot re-access the level again.

Frozen bloon glitch[]

  • When a Ice bloon is popped near a 'special' bloon type, the bloon will not appear frozen, but will still be unpoppable by darts.

Bloons 2 Mobile[]

Save locked achievements[]

  • Achievement progress is tracked based on save. One side effect of this method is that if you make progress on achievements on one game center account, switch accounts, and then start working on more achievements, any achievements or progress earned on that other account will not transfer to the new account, and no progress can be made towards those achievements.

Six Figures name[]

  • The achievement Six Figures erroneously appears as Million Pops. Likely the original intent was the achievement would require 1 million pops.

Bloons Pop 3[]

Bloons pop 3 invisible bloon

The Pink bloon turned invisible!

Hint Glitch[]

  • After earning 200 points, the player has unlimited hints, even if the player has no points.

Invisible bloon glitch[]

  • Rare bug when a player attempts to buy hints when no points.

BTD1 (and BTD2)[]

Main article: Known Bugs in Bloons TD 1 and Bloons TD 2

BTD3[]

Giant missle

"DEAR LORD..."

Huge missile bug[]

  • 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)
    • This only happens when the Bigger Bombs upgrade is purchased, this may have been done on purpose due to the name of the upgrade.
Beacon glitch

Isn't the beacon supposed to be more expensive?

Lack of Money Bug (Very minor)[]

  • 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 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.

Another Monkey Beacon bug[]

  • This only works too in BTD3, when you have a Monkey Storm Beacon, activate Super Monkey Storm (you must activate it from the tower menu) and KEEP your cursor on that Super Monkey Storm icon. Then it will show the "TOP SECRET" description, but if you drag your cursor and hover it back, then it still show the Super Monkey Storm description.

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 drop-down is still there, click where on the screen you want to place the tower. (Also works on BTD 1-4)

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.

Start Round Glitch[]

  • On the First track or the fifth 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.

Stacked Pineapples[]

  • The pineapple road item explodes three times at the same moment.
    • This triples their pierce and damage, making pineapples very powerful.

BTD (iOS version)[]

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.

Freeplay on a new save[]

  • New saves can inherit the freeplay ramping of a previous save if you fail it on a high enough round. Fixable by force closing the app.

BTD4 and BTD4E[]

Main article: Bloons TD 4/Known Bugs

BTD4 Mobile[]

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.

Farm Glitch[]

  • When selecting a farm, sell it, then quickly select another tower before the upgrade menu disappears. The farm will disappear, but it will still give its income when the round ends (there is no visual display of the +80 though). With Monkey Tycoon, you can get infinite cash this way.
  • For apopalypse mode, you can simply exit in and out of the game to gain infinite cash (and lives, with Healthy Bananas) that way too.

Incorrect RBE[]

  • For some reason, Round 27 seems to incorrectly display an RBE value of 4 to the player rather than the actual 400. This was patched with an unknown update.

Non-Arctic Arctic Wind bug[]

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.

Debug Glitch[]

  • Sometimes when "monkeying around" with the menus, you can enter a game with infinite cash (doesn't work with challenges or deflation).

Unachieveable[]

  • A severe bug causes achievements to disappear, even if the player has gotten them. This is temporarily fixed by completing a round on any gamemode, but must be constantly done each time the game is opened.

Instant Mortar Reload[]

  • Pressing the Target option on the Mortar Tower causes it to instantly stop firing and immediately reload a shot. This allows the Mortar to begin shooting a second shot as soon as the first shot lands, if the player is able to rapidly press the target button and select a spot. This bug does not exist in the Flash version.

BTD5 Flash[]

BTD Battles Flash[]

BTD Battles (iOS,Android and Steam)[]

Main article: Bloons TD Battles Mobile/Known Bugs

Bloons Super Monkey[]

Stage Repeat Glitch

  • Observed after waiting on the upgrade screen at the end of Stage 1 without buying anything for about 2-5 minutes. After hitting the "Next Stage" button, you will replay Stage 1 instead of moving on to Stage 2. All the bloons will have respawned, and you will keep all your blops and upgrades. The bloon at the top of the screen that tracks your progress towards the bronze/silver/gold trophy will be as full as it was when you last finished the level. At the end of the level, the game will add the number of bloons you popped the last time(s) you played the stage to the number you popped this time to calculate your score. This glitch can be repeated multiple times in succession.
  • Currently, it is unknown exactly what causes this glitch and it has only been observed on IOS (mobile).

Invisible Sun God Bug[]

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

Bloon Cycle Bug[]

  • When viewing the .SWF file or using another method of seeing outside the screen, if the game is paused while Bloons are spawning they will loop through bloon types from red to ceramic repeatedly. When the game is resumed the bloons spawn as the normal type.

BSM2 Flash[]

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.
  • Sometimes it occurs in level 1-5 just for collecting all Red Blops from all non-lead bloons

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/research 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. Also works to researches, though you may get it after refreshing the game.
6

An example of the Mirrored Boss glitch in BSM2. Don't they know I'm allergic to seafood?

Mirrored Boss glitch[]

  • Sometimes, in Stage 5 of Deep Bloon Sea, the Calamari Blimp glitches out and it will display a mirrored version of itself in the upper corner while the real boss might come down all the way to the end almost immediately, making the player lose the level.

Ninja Kiwi flashing lock bug[]

  • Occasionally, BSM2 will fail to identify the site of origin, giving the player the message "play now on Ninja Kiwi" when the player plays the game on Ninja Kiwi.

Wrong Background Glitch[]

  • When you play a level in hardware, it shows the true background of the level you are playing. However if you change to software, the level shows the incorrect background.

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[]

  • 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 player beats a level without touching or doing anything, earned blops will be different than before.

BSM2 Mobile[]

BSM2M Explosive Tornados

Explosive tornadoes of doom annihilating Blastapopoulos!

Blow Back Crash[]

  • If the player uses the "Blow Back" ability when there a lot of bloons on screen, the game will crash.

Permanent Glue Striker[]

  • If the player collects a Glue Striker or Corrosive Glue powerup while the Sticky Shots powerup is active, then the collected powerup will last the entire level.

Homing projectiles rehitting the same bloon[]

  • Using any weapon with Neva Miss Targeting results in upgrades being able to re-hit the same bloon multiple times. This has devastating results when combined with Explosive Shots, a powerup that increases pierce of a projectile by 10, and can notably produce results such as Bloon Busters exploding multiple times for massive damage, or tornado cores creating constant explosions.

This also works with Ricochet Rangs, Shuriken, and Radar Glaives without any powerups, since they also have built-in homing.

Force Close to Keep Powerups[]

  • Force closing the app before a level is complete will not use up any powerups selected for a level. If you try restarting the level normally or complete the level then the powerup is used up.

Blops Carrying Over From Replays[]

  • After pressing the replay button and beating the level again, the blops earned counter displayed after beating a level will accumulate on top of the previous level's blops. This can theoretically be used to earn extraordinarily large blop counts to double with an Ad 'Training Video'.

BMC Flash[]

Main article: Bloons Monkey City Flash/Known Bugs

BMC Mobile[]

Main article: Bloons Monkey City Mobile/Known Bugs

BTD6[]

Main article: Bloons TD 6/Known Bugs

BATTD[]

Infinite Ghost Money[]

  • Ghost Bloons are immune to damage from non-energy characters like Finn without the right trinkets but many trinkets still have an effect.
  • By equipping a melee character with the Thief King's Dagger and the Power Ring of Strength the character will get $2 in game cash per attack and indefinitely stall the ghost bloon, so if no other character pops it they will slowly accumulate infinite money for you.
  • Finn is the best character with his good attack speed and the Right in the Glubs upgrade that occasionally lets him to full speed burst of attacks (Stunned bloons also don't go backwards).

Flying Kick Misplacement[]

  • Sometimes, when the player moves Finn close to a MOAB-class Bloon with the BMO's Skateboard ability and he uses his Flying Kick attack on it, he can fly back to the place he was before the player moved him. He can still attack and kick the MOAB-class Bloon because the game still registers him at his new position. When Finn uses his Flying Kick attack while the bug is active, he will fly quickly to the MOAB-class Bloon to kick it.

Hypersonic Missiles[]

  • Commander Cassie with the help of Speed Boosting trinkets (Warning Horn,Plasma Goggles,Etc.) can allow Commander to have massive attack speed buffs on her Sidewinder Strike ability. Activating the speed buffs and Commander's Ability on a specific order allows the planes to shoot unusually fast. The DPS of it is comparable to multiple Vengeful Sun Gods as the glitch allows the planes to melt Fortified BADs.
  • As of Right now, there are multiple instances of people being able to pull off the glitch with different setups, Speed buffs and order of ability activation. More Clarication Needed.

Hiding in Castle Walls[]

  • If Lady Rainicorn is placed behind a wall in Fire Kingdom Castle, the player can place any land tower behind all walls, excluding the east wall and the center passageways on the north wall.

Misplacement/Misselection over Fountain[]

  • If the player selects or hovers a tower over the fountain in the map Candy Kingdom Streets, the player's tower input will be adjusted to the south from the actual input, causing the tower to be placed or selected much lower than the player's input location.
    • Disabling Drag & Drop (Click & Drop on desktop) may help with the placement of towers behind the fountain.

Cannot confirm placement[]

  • Sometimes, the confirm placement button does not work while using Drag and Drop (Drop and Lock in mobile) after selecting a special surrounding item that uses in-game cash when the player has not been able to afford it.[1] This can be fixed by selecting the object in question again when the player can afford it.

Non-attacking Jake[]

  • Occassionally, Jake will no longer attack bloons nor lick nearby towers after a while into a game. It is unknown what exactly causes this, (though this has occurred when he is upgraded, he is not next to Finn, and/or the device is lagging) but selling and rebuying him should fix this issue.

Infinite Energy Loop[]

  • If the player pauses the game as Sam initiates her beam attack, the sound may persist indefinitely until the same or next beam attack finishes or exiting the current game. Can also occur for Flame Princess with Flamethrower or Heat Ray.
    • If the game is restarted while the sound is still present, it will not turn off if the sound effects are off.

DDT Permastun and Loot Stacking[]

  • Shoko's attack causes various effects to stack on DDTs. This can cause the DDT to be permanently polymorphed (or some other stalling effects like Crystal Gem Apple's stunning), and can cause a ridiculous amount of loot to drop if it got hit by a Thought Cannon Wand user multiple times.

Star Level Mismatch[]

  • Jake and Marceline when selected in the characters menu will always show their actual star levels even when Tuxedo Jake's Full Orchestra is in effect, despite both having modified star levels as seen when selecting them on the map. For example, a Level 7 Jake will display Level 7 in the characters menu, but selecting him on the map will show Level 10 instead.

Levitating Tuxedo Jake[]

  • When activating Rock Out!, Tuxedo Jake may freeze in place during his jumping animation while transforming.

Crystal Gem Freeze[]

Discarded Chest[]

  • If a Daily Quest chest is discarded, and another one of the different tier is chosen before closing the Daily Quests, the icon of the discarded chest will show in lieu of the new one.

Faster game while lagging[]

  • When a player's device is lagging[how?], the game may send bloons sooner(?), causing rounds to complete faster than usual.
    • This has allowed a speedrunner to complete Treefort Exterior, which normally takes 54-55 seconds to complete at the quickest, in 34 seconds.[2]

Land allies placed on water[]

  • If a character/ally that is placeable in water is put there. And if with Martian Games mode: Shuffle, a character placeable only in land may be switched into the body of water. This will continue until they are switched back to kand.

Bloons Pop![]

Exploding Bloons[]

On Version TBA, some bloons will make an explode effect when popped. The "explosions" do not pop nearby bloons.

Floating Monkeys[]

BloonsPopBFB

Partial screenshot of the Behemoth boss level where a Super Monkey was stuck on the middle of the screen

On Version 3.0, there was a bug where all monkeys were stuck in the middle if another monkey is swapped with another monkey too soon.

Stuck level completion[]

The Pop and Awe powerup can stun bloons even when they are to the left or right of the screen. If the stunned bloons happen to be the last remaining bloons, they could prevent the player from completing the level within the next shot.

Not cycling from leftmost monkey first[]

Secondmonkeyonlybug

If the player selected the second or third monkey in the active shots after completing a level, the game may not automatically switch to the first monkey right before Golden Bloon Time. The game then proceeds to use shots starting from the selected slot, cycling through the last remaining shots from the right. Should the shots apparently end, the game will generate shots until the shots counter reaches 0, leaving the leftmost shots unused.

Bloons TD Battles 2[]

Auto Surrender glitch[]

There’s a glitch where the game becomes unplayable and auto surrenders you and you cannot play for a while or else it will keep happening, there is no known way to fix this problem right now

Desync Glitch[]

There's a glitch where one opponent can abuse that put the game to a complete stand still. More details needed.

Auto Sending[]

When playing, there is a glitch you could perform by minimizing the game then opening it again while sending bloons. This makes it so that the bloon you were sending is automatically sent without having to press anything (pc only).

Private match exp glitch[]

While playing private matches, the exp is doubled compared to what it should've been.

Sentai crooked neck[]

Sentai churchill crooked

When using Sentai Churchill's default lose animation, his head goes crooked. This only occurs since Version 1.2.0; previous versions did not have that bug present.

Mismatched R4 Heroes[]

There was a bug in 1.3.0 that made heroes appear mismatched. However, the heroes in the game are correctly identical to each opponent. Fixed in 1.3.1.

Tiny R4 Heroes[]

Tiny dj ben

There was a bug in 1.3.0 that made heroes appear tiny on the screen. Fixed in 1.3.2.

Ad not Playing[]

Screenshot 20231215-004139

Ad not Playing in BTDB2

When starting a match sometimes players would encounter an ad, and in this case, the screen would be cut and a blue screen with bubble would appear making the ad not play and the 'x' button not appear. It would happen frequently (mobile) (playing on version 3.1.0)

Shadow Hero[]

Occasionally, the game may introduce a shadow hero if it cannot find an appropriate hero. A similar bug occurs in a bug where it was possible to play Dart Monkey for the hero slot.

Patched[]

GLITCH

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

Save Bug[]

  • Saving the game in BTD4 originally required a MochiGames account, prior to Ninja Kiwi's account system being used as a replacement. Ever since MochiGames shut down, the player's game hasn't been able to save, even if the player presses the Save button in a game. The bug has been fixed; a Ninja Kiwi account is now required to save your current game in BTD4.

Bee Bloon eating Darts[]

  • After the bees from a Bee Bloon vanish in Bloons 2 Mobile, the monkey throws a dart prematurely. Patched with the 1.1 update.

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.

Engineer Bug[]

  • If you upgrade a monkey engineer to 0-4, then upgrade it to 1-4, the engineer's appearance 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. This was fixed in 2.1, but when the Odyssey mode was introduced, the bug was put back in, but now only the appearance is changed. This bug was fixed again in December 4, 2015.

Unlimited NK Coins/MM Glitch[]

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

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.

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 reloading the game.

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 no Site do jogo

I AM ON NINJA KIWI YOU DUMB GAME!

Bug when logging into the 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".
200px-Abilities glitch

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

Special Abilities Bug[]

  • 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 (April 2, 2013) 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 the same April 2, 2013 update.

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.

Negative XP Bug[]

  • In BTD5 Deluxe, when it was first released, Ice Tower's XP was bugged and had negative values causing it to never level up. Fixed two days after release.

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.

Fast Upgrade Glitch[]

  • In BTD5 Deluxe, when playing the Fast Upgrades special mission, it was possible for a tower to upgrade to an upgrade you haven't unlocked yet. This was patched on August 26, 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.

Monkey Dollar0 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 was 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 two weeks after Bloons TD 5 was officially released.

Tack Awesomizer Bug[]

  • Road Spikes do 13 pops instead of 22 with Tack Awesomizer.

Pro Tribal Turtle Bug[]

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.

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

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[]

Fast Sandbox Bug[]

  • When Fast Track Mode is turned on, and you go into sandbox mode, you will only have the Fast Track Cash even though it looks like you still have infinite.

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.
03192012$$$(00)glitch

The Treasure Chest Glitch

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.
BTD5 News Table Bug

The News Table Bug

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.

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.
Screen Shot 2013-07-09 at 8.06

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

Road Spikes Bug (minor)[]

  • When spamming road spikes in BTD5 iOS, and the player ends up with less than $30, the player could buy their last pile of Road Spikes for less than $30. Fixed in version 2.1

Stupid Mortar Glitch[]

  • 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.
321

Get ready, Wait and win! Piece a cake.

Disconnection Bug[]

  • After you and your opponent choose towers on Bloons Tower Defense Battles iOS, one player will see the waiting for opponent screen, while the other one is already playing round 1. After Round 1, the game doesn't start Round 2. The player who first played Round 1 will get infinite money in several seconds.

Banana Farm Flash Crash bug[]

Unnecessary Lag bug[]

Bullet/Slo-Mo Matrix speed bug[]

  • In Bloons TD Battles, as of October 14, 2013, there are added codes for an anti-hack system, which never got implemented until a few months later, adding some memory. 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.

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

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.

Towers Placeable Everywhere[]

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 v1.12 BTD4 original and v1.18 expansion)

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. Fixed in version 2.1

Sextuplet Darts[]

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. Fixed in version 2.1

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. This was fixed in version 2.6.1.

Temple Trap glitch[]

  • Similar to Spectre stole ground zero's ability glitch. activate the glitch with a super monkey. upgrade to temple of the monkey god with no super monkey on the screen. The temple will appear for a split second, sacrificing all towers around it like an average temple, then disappear. Again, this was patched in the same update.

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
    4 4 Monkey Ace

    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.
  • You can get an unlimited amount of monkey aces with this glitch.
  • This was patched in an update. It still works, but you can't upgrade the tower.

Super Overclock Glitch[]

  • Overclock can stack with most towers, allowing them to become extremely powerful. In version v150831 however, this has been patched.

No Money Glitch[]

  • When you use up all your money on the tutorial and it asks you to upgrade your dart monkey beacause of camos then you will not get extra money and you cannot finish the tutorial. Now, the game gives you money if you don't have enough.

Ability Stutter Glitch[]

  • If Active Ability is at rank 5 or higher, using an ability will cause towers to 'stutter' (even Banana Farms), resetting their attack cooldown. This makes supply drop farming a lot less effective, unless you have a couple Absolute Zero abilities to freeze the bloons when the stutter happens. This is demonstrated here: https://www.youtube.com/watch?v=8u2caspj7GY

Cheap Win[]

  • If you skip the map when the tower selection screen reaches the last second, your opponent gets a random tower loadout. Your opponent will be unable to change the towers since the Ready button will be pressed automatically. However, your opponent can still counter the trick by skipping the map after you do before you choose your towers and press Ready. Technically this is not a glitch but a strategy, though.

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.

Full House Infinite Towers Glitch[]

  • By having the shadow ninja double ability unlocked, you can use the ability, click on the shadow ninja, and sell it. This will allow you to buy 1 extra tower. You can perform this multiple times to increase the amount of towers you can place.

No Monkey Sub in Special Missions[]

  • Very minor, but before it was announced on the site with the Monkey Sub update, the player could not use the Monkey Sub in Special Missions. This was fixed when Ninja Kiwi intentionally announced the Monkey Sub.

Reverser Difficulty Bug[]

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

Less Towers Bug[]

  • This bug came with 3.1 update. It appears at missions with limited number of towers at a time. It decreases the number of allowed towers in the field by one. For example, you can put 4 towers only in Full House Special Mission instead of 5. However, this bug don't affect the number of towers from one type. For example, you still can put 3 towers from each type in Third Time's a Charm Random Mission. This was fixed on next update.

Weapon Type[]

Present since 1.0, patched at an unknown date.

After beating level 1, the game prompts you to select a core weapon. By selecting the core option but not a core type, then changing language, and finally purchasing a core of the player's choice, it is possible to permanently disable the ability to purchase arm upgrades. Each time the game is reloaded, opening up the upgrade screen on arms will display a blank upgrade cost, no icons for the three main weapon types, and while tapping the core will let the player upgrade like normal, tapping the arm weapon slot will do nothing.

Precision not working[]

First present in 1.0, patched in 1.1.1.

In BSM2M, precision was formerly unachieveable. While not possible with normal methods, it is still possible to unlock through modding or loading a save from 1.1.1 or later on versions 1.0-1.1.

Super Wired Funds[]

  • You gain blue and red blops a lot faster than normal. However this has been patched on an unknown version..

Reward Wants 101%[]

  • Sometimes rewards won't let you collect it at 100%. This was due to the achievement progress rounding the percentage to the nearest integer, making it seem like you've completed it when you still need a little more. This has been fixed in version 2.0.

Regrow DDTs Bug[]

  • In BATTD, if a DDT is popped, the children were able to regrow back into DDTs. It has been patched in version 1.3.
