this glitch seemingly permanently plays a weird, smashing like sound over the music that should be playing. It is uncertain how this glitch occurs, but it seems to be linked with the monkey knowledge menu.
Triple darts don't like enhanced eyesight glitch[]
Sometimes a 2/3 dart monkey shoots one dart at each time.
Permanent SMFC glitch[]
If you place down a few Dart Monkeys, upgrade the LAST Dart Monkey you placed to x/4, use the ability, then sell the SECOND TO LAST dart monkey you placed, the remaining Dart Monkeys will continue to remain as Super Monkeys even if the x/4 Dart Monkey is sold. The other Dart Monkeys can be upgraded to any upgrade and they will continue to throw darts at hypersonic speed.
Strange Monkey Knowledge showing glitch[]
Ok. Please tell me why that dartling gun and mortar tower(monkey)'s book's appearance look so strange? They are rank 10, not 11. Ok, they are evil sometimes.
When you open a pack and discovered a card that can directly causes your Monkey Knowledge books to level up (only works for lvl 5 to 6 or lvl 10 to 11, for example a lvl 10 mortar book and after you collect the card it goes to lvl11), but you haven't collect the card and clicked the MK book, you will see that that tower's book has a one lvl higher book appearance just like the pic. 3 above.
Of course, after you collect that card, the book will turn to the new level and so the correct appearance.
Smart Glaives bug[]
When a 2/x Bommerang Thrower throws glaives, it sometimes riccochets, even if the Glaive Riccochet upgrade isn't bought.
Beacon on building Glitch[]
Sometimes the Bloon Beacon will appear on a building. To fix, move the building. It is still possible to capture a captured area for more easy loot, however this won't increase the tiles captured amount. This can happen more commonly when nearly the entire game world is cleared of Bloons.
No lives left but win glitch[]
The Bloonarius is so evil! He commit suicide before killing me!
When fighting any of the four Boss Bloons (Bloonarius, Vortex, Dreadbloon, or Blastapopoulos), when you defeat the boss and run out of lives just in time, you see the defeat message, saying "DEFEAT! ...But the boss is damaged. Chase it down and try again!" In the same time, the boss is currently in its death animation. And then, the victory message is shown after few seconds. You will still win the fight and claim the reward.
Wrong City Level Glitch[]
If you go into the My Cities selection screen, it may say that your city in Grassy Pass is in a city level higher than the actual city level in the first city. (e.g. your first city is level 24 but the My Cities selection shows that the first city is level 25.)
Cash Starve Glitch[]
Sometimes when you go into your city, all your Banana Farms will not produce any city cash. To fix this, reload Bloons Monkey City again.
Pacifist Mode Glitch[]
Sometimes when Pacifist Mode is on, your city can still get attacked even though Pacifist Mode is activated.
Game Pausing[]
Also works in BTD5.
Let's say, we have a 4/0 Ninja Monkey, and it will pop Bloons in SLOW MOTION while the shurikens are 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 Seeking Shuriken upgrade can/will only target the closest Bloon, regardless of targeting preference. If another Bloon passes them, they will face the first one, 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. This happens in BTD Battles as well.
Damaged In-Construction Buildings[]
Sometimes, when your buildings are damaged after losing a Monkey vs. Monkey defense without sufficient City Cash, in-construction buildings can get damaged, adding up the damage time to the construction time. This can only apply to Unit Buildings, provided that one is currently in construction.
Warning: It is possible but very rare for the damaged building's construction time to stop completely. Should this ever happen, the only two solutions to fix this are to either finish the building with Bloonstones, or contact Ninja Kiwi.
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 can't put the villa in its original spot. Also, when moving the villa, the tile where the building disappeared will have a green-striped pattern. The building will reappear when the player moves the villa off of the spot and reloads the game.
Why can't I build a Banana Farm here? (from BMC Mobile)
Banana Farms can't be built on Volcano tiles[]
For some reason, Banana Farms cannot be built on captured Volcano Terrain tiles, even though said tiles appear to look like land tiles. This also applies to the mobile version as well, although it could be intentional as it would be kind of hard to grow a banana farm on a volcano in real life.
Bloon Sending[]
In the closed beta version of Bloons Monkey City, it was possible to send Bloons to yourself by pressing certain keys on the keyboard. Players can even send Bloons they have not fought yet, like pressing the '4' keys summon D.D.T.s. Ninja Kiwi actually left this in the game for testing, and they removed this when the game was officially released.
Defended Attack Bug[]
Rarely, 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.
Pillage it all![]
When winning an attack, you can get double, triple, or even quadruple the original pillage amount of city cash. The additional money will not be shown at first, but after refreshing the page or switching cities the value will update. This also goes alongside the Careless City Cash Counter Calculation glitch.
MOAB Class Bloon Glitch[]
Sometimes, when you are playing a track with multiple paths, MOAB Class bloons (especially BFBs and ZOMGs) can start on one path, disappear, and reappear at the beginning of the other path.
ZOMG Sabotage Glitch[]
Some Packed B.F.B. or Packed M.O.A.B. tiles may not show any Z.O.M.G.s, even if they are the highest Bloon type shown for the attack.
Contested Territory Reward Bug[]
If the CT panel is open when the milestone/occupation event ends, the next event will start shortly before the map changes, giving any possible rewards for the new event as well as the previous one.
For example, if you held CT for 1 day while the milestone event was on, you will also get the 1 day occupation reward when it starts, along with all the previous occupation rewards. If you go for the 2 day occupation now, you have to hold the CT for 2 more days since the capture times are reset when the map changes. You also can't recollect any rewards you've already gotten by hitting the desired hold times.
Contested Territory Fail glitch[]
Sometimes if you win a CT, you will not be holding the territory, even if you are first mainly after one day. It could also happen to other winning opponents.
Sometimes, your total time you held the territory will reset. This is fixed by refreshing the page.
If you begin a CT round directly before the bloons retake the territory, and win the CT after they would have taken it back, the territory will remain unclaimed.
Ninja Kiwi said it is by server failure saying that the game may not remember the process of CT and may say someone else took it.
Sometimes, the page will not load properly, showing all 6 cities names as Player Name.
Infinite Cash For CT[]
If you win a CT, wait a while. When holding, the farm cash exceeds into hundred millions of cash after a while. Abusing the glitch can get your account banned.
I hope those cash trucks can carry that much- i'll be upset if it doesn't. Well, REALLY upset...
Sentry range bug[]
For some reason, if you click on a sentry that doesn't attack any bloons in its duration and the time expires while the stats for the sentry are still shown, its range will still be on the screen. clicking on one of the targeting options will cause all four buttons to disappear.
Godly Or Wacko Sentry Bug[]
HEY! NO SENTRIES CAN GO ON WATER OR THE TRACK!
Strangely, when the player buys at least a 1/0 Engineer, and if there are towers that fill the 1/0 Engineer's range and when there little to no space for sentries to randomly spawn within the Engineer's range, sentries will start spawning on the pathway where bloons travel or if the Engineer's range covers water then sentries can start spawning there too.
Incorrect Music Glitch[]
Sometimes when you play a contested territory (possibly any tile) in your second city, you'll go back to your city noticing it is playing the tune from the 1st city.
Red Hot Spikes Glitch[]
When you buy red hot spikes with fewer than 5, they are free. Possibly intentional.
Lose when you haven't glitch[]
If you click on monkey boost when you have fewer then 5 and press cancel, it will say that you ran out of lives, even though you still have lives. While it's saying that you've ran out of lives, and you really do run out of lives, the screen will get darker. Exit and re-enter the same level and the screen will still be dark. It won't let you place anything, so you'll have to reload the game.
No Victory Bug[]
Sometimes after capturing a tile, it has the appearance of a non-captured tile in your city until you move your mouse off of it.
I Lost All My NK Coins Bug[]
Occasionally, the game may not allow you to spend any Ninja Kiwi Coins when purchasing Premium Buildings, Monkey Knowledge Packs, or Bloonstones. If the page is refreshed, however, any purchased Monkey Knowledge Packs will disappear, and your NK Coins will not be given back to you. Should this ever happen, you can contact Ninja Kiwi (via support@ninjakiwi.com) to recover any lost NK Coins from this bug. They have found this and is confirmed known; they are working on it currently.
Game Disconnect Bug[]
When you collect money/bloontonium from a specific building the game may give a server error causing you to reload the game. After that you may duplicate or lose all the resources. The errors should stop after around an hour.
Moving that building will error the game, forcing you to reload and the building will be duplicated.
The game may also error when spending Bloonstones, which in that case you lose the bloonstones.
The game may error when you claim a tile. You might lose the tile and all rewards. If that does not happen then you will lose the money gained from the tile.
The game may error just randomly after a while.
Descriptively, certain occasions can pop up an error that says Server Error with a monkey holding a cord. Retry will not do anything and after a few attempts the monkey is electrocuted and the Data Connection Error is given, stating that you must re-connect to the game server. After that, you are sent to the title screen. Clicking play will make loading stuck on "Connecting to Server..." This forces you to reload the game.
Temple Misdirection[]
When attacking relatively weak bloons such as blacks, whites, or zebras, a Temple of the Monkey God may very briefly fire directly to the left, even if there are no bloons in that direction. Influence of a Monkey Village does not affect this glitch. This can happen with any tower.
Flash Crash of Death[]
Usually caused by a old or laggy computer or by an outdated processor, if you win a tile and then flash crashes, you will not win the tile because the game did not have time to save your data. The only workaround is to use a high end computer or upgrade your processor as flash will less likely to crash on a better computer or processor.
Re-winnable Missions[]
Sometimes, when transferring from your first city to your second, two messages will appear, one after another. The first says that you have completed the Longer Darts mission (which requires research of Long range Darts for the Dart Monkey), and the second says you have completed the Better Boomerangs mission (which requires research of Multi Target for the Boomerang Thrower). You receive the indicated rewards for the two missions if you click the continue button. This glitch only occurs if you have already completed the missions by doing the required research.
Ultra-Temple Glitch[]
Occasionally, when sacrificing a 4/x Mortar Monkey, a Temple of the Monkey God will become incredibly powerful, being able to completely destroy even Z.O.M.G.s before they fully appear. This makes it impossible for anything to get past the tower (unless in a high round on Contested Territory). While it might be said that sacrificing a 4/x Mortar Monkey would make each shot from the Temple pop five layers, the fact that it only happens every so often identifies it as a glitch, no matter if the Mortar super-powers the Temple or the Temple fails to absorb the ability of the Mortar.
Since when are there two Bloon Research Labs here?
Duplicating Bloon Research Lab Bug[]
When a Bloon Research Lab finishes an upgrade, it may create a duplicate of itself 2 tiles below it, replacing anything that was previously there, even if the tile is not captured. If it replaces a building larger than 1x1, then the previous building will still exist around the lab, and the bug is corrected the next time the city is loaded. If the bug occurs in one city, it will probably occur in the other. The screenshot shows a second Bloon Research Lab that took the place of a Dart Monkey Hall.
Repeating Quests[]
Very rarely, the game can bug out when loading a city, and all of the quests will reset and can be re-earned. Some of them will be completed immediately, like having a certain researched complete, but others will require you to complete a tile to earn them again. All of the money and XP are earned again like normal and can drastically boost your cash and experience. The screenshot to the right shows some of the quests that returned.
Tunnels Bug[]
On the desert map 'Arrow', road spikes can be placed on the tunnels. The road spikes will disappear, but they are actually hidden in the tunnels. Also, any tower can attack bloons in the tunnels. Bloons can even be frozen in the tunnels!
Careless City Cash Counter Calculation[]
The amount of City Cash is indeed full, but the counter did not display its counter right.
In BMC, after Monkey Vs Monkey messes around with the money and makes the amount of money owed is greater than the money owned, the counter gets confused and underestimates the amount of City Cash the player has. This also caused the player to be able to buy upgrades that are higher than what the counter claims it to be. Unfortunately, the actual amount of City Cash held cannot go further than the correctly stated max amount. Possibly fixed on the August 2015 update.
Ray of Doom blackens the screen bug[]
Sometimes, when the player tries to upgrades a Dartling Gun to Ray of Doom, the map turned black thus forces the player to quit the map.
Overclocking Bug[]
When you click on the overclock icon just before the game is over, the next tower you place in the next tile you capture gets overclocked for free.
Lonely Captured Tiles Bug[]
Tile unconnected to the rest of the city.
This bug can occur if a player captures a tile while he/she is not connected to the NK server. If the player captures an adjoining tile afterwards when he/she IS connected the NK server, then reloads the game, the game will occasionally fail to load the tile captured while offline. This results in a captured city tile/tiles which are unconnected to the rest of the city. The tile captured while offline must be recaptured.
The Caves Terrain with wrong icon[]
This is not a Grass Terrain; this is a Caves Terrain!
The icon for the Caves Terrain is incorrectly displayed as the Grass Terrain icon when replaying tracks, or through Contested Territory. Nevertheless, the Caves Terrain still plays that correct track if track is replayed, despite different Favors and Restrictions.
Backwards progress[]
Sometimes when moving from Grassy Path to Bloon Dunes or vice versa, the progress is reset to what has been done at the start of the latest gaming session of the player. This may be fixed by simply waiting for a "saving" bunch of words to disappear before traveling between cities.
Similarly, an upgrade in progress of buying upgrades may sometimes be marked "cannot afford" even though there is enough City Cash to buy such an upgrade. This can affect the Double Shot upgrade.
The solutions to these include:
Refreshing the game every few hours, if playing for very long periods.
Give the computer a rest from BMC.
A Special Terrain tile!
Fog Bug[]
Sometimes after completing a tile, the fog around the city will disappear, allowing you to hover over all of the tiles on the map and see the tiles that would normally be on the edge of the fog without difficulty. This happens most if the computer is lagging.
Building on Territory[]
HEY! THIS IS OUR LAND!
Rarely, when you reload the game after a large building is finished (Monkey Ace or Super Monkey), one of the tiles captured will be displayed as not captured, and the building will be on land that is not captured by the city.
No Monkey Teams for you[]
Sometimes Monkey Teams fails to realize that the player has used all of the eligible towers and does not reward the player its reward, even if not using any non-eligible towers. This can be fixed by refreshing the game every time new events come.
On the Flash version, finishing a game with the monkey team towers when the event ends in the middle of it will cause the game to hang and force a refresh.
Sticky Dragging and Stubborn Clicking[]
Sometimes when running BMC for too long, clicking and dragging to select a tower does not work as well and forces the player to manually drag the tower into the gameboard instead. It also causes clicking of a tower to be clicking on the wrong tower or on the wrong part of the screen. This can be fixed by refreshing the game regularly if deciding to leave BMC to run for long periods of time.
Floating MvM upgrade description[]
This upgrade description of Camo Bloon research floats
Occasionally, placing the cursor over the research icon leads to a constantly floating description bubble that does not stop even when the cursor is out of research icon.
Permanent Super Monkey Fan Club[]
If you place Dart Monkeys, upgrade one to x/4, and sell the last one you placed, you will have an infinite Super Monkey Fan Club. This is similar in function to the Overtime SMFC glitch, only you can do it intentionally.
If the last dart monkey is the one upgraded to SMFC or increases the dart monkey count beyond 10, then the glitch will not work!
Combining Permanent SMFC with Spike-O-Pults can trigger the Hypersonic Spike-O-Pult glitch as well.
Repeating Info glitch[]
Man, I feel sorry for that player, they only wanted to try out MvM
Sometimes the same information may repeat multiple times.
"Where'd my towers go?" glitch[]
Sometimes switching between the game and other tabs during heavy lag will cause all active towers to apparently vanish for a brief period of time. They do reappear quickly and function normally even while "gone".
BMC saving glitch[]
Sometimes the game will be constantly saving. This causes you to lose progress and messes up your battles record. MvM will be saved in your Battle History page, but will not show up in "Attack wins ?/?" or "Defensive wins ?/?". Your city cash/bloontonium will be reset to the start of your session, but attacks defended stay defended. Any cash won from successful attacks will disappear. Any money in farms will be reset to the start of the gaming session (probably full capacity) but CT cash collected will be lost. There are other things that may not be determined.
To prevent this glitch, ensure the computer is a strong computer, and that you ensure that the game is continually refreshed if the computer sleeps.
Single Darts[]
Triple Darts is now Single Darts
After the duration of a Super Monkey Fan Club is over, sometimes the Triple Darts and Super Monkey Fan Club Dart Monkeys will subsequently only shoot single darts. Fortunately, this bug is rarely seen outside a very few occurrences.
Repeating Tiles[]
Hey! I already beat this.
Whenever you capture a tile, it ask you to beat it again also whenever you try place down a building it's same thing.
Patched[]
Shouldn't this be red and not black?
Black Bloon Sharp Shuriken Bug[]
Sometimes a discoloration of the the Sharp Shuriken upgrade for the bloon to be black and not red. It was later patched.
Spike Factory shooting Spiked Balls even without upgrades[]
In Bloons Monkey City, when the Non-Stop mode update was first added, the Spike Factory was able to shoot Spiked Balls, even if the tower isn't upgraded or the upgrade hasn't been bought. This was quite game breaking, allowing for some tough non-Desert tiles like Ceramic and even M.O.A.B. tiles to be beaten at early city levels with almost no trouble. This is demonstrated in the following video: https://www.youtube.com/watch?v=hyCR_cGFDQg
This also allowed for Spiked Balls to combine with MOAB-SHREDR Spikes, allowing then to deal extra damage to Ceramics and MOAB-Class simultaneosly, or when upgraded to Spike Storm, you get a Spiked Ball Storm!
Shortly after Junior Monkey made the video, it has been patched, as of December 1, 2014.
Repeated Winning Bug[]
When you win a raid, it keeps popping 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.
