Bloons Tower Defense 6 is the latest game in the main Bloons Tower Defense series. The game introduced 3D graphics and Line of Sight, new bloon types (specifically the Purple Bloon, the Fortified property, and the Big Airship of Doom), Heroes, 5th tier upgrades, a third upgrade path for each monkey, and a Trophy Store. It was first released on June 13th 2018 for Android and iOS.


Main gameplay

An example defense on the map Dark Castle.

Gameplay in Bloons TD 6 is similar to previous games, with monkeys popping Bloons. Bloons TD 6 introduces many new game mechanics such as Purple Bloons, an all-new MOAB-Class Bloon (the B.A.D.), new hero towers, 5th tier upgrades, and a third upgrade path for each monkey. D.D.T.s, which first appeared in Bloons Monkey City, also return. The new Bloons have different properties, such as Purple Bloons being immune to fire, plasma, and energy weapons, and Fortified Bloons, which are stronger variations of their regular counterpart (the Fortified property will double the health of all bloons it is applied to except for leads, which quadruples its health).

Each game progresses using rounds. These rounds gradually introduce more Bloon types and get harder the later the player progresses. Before starting a game, players are prompted to choose a mode - Easy, Medium, or Hard - and select a sub-mode. The variety of modes in Bloons TD 6 allows players to play the same map in many different ways, making the game more diverse than previous installments in the Bloons TD series. Upon completing a game, players will get a certain amount of Monkey Money based on the difficulty of the map chosen, and the mode chosen. After a map's first completion on a difficulty, the amount of Monkey Money rewarded upon completion is significantly reduced.

MOAB-Class bloons such as the M.O.A.B., B.F.B., Z.O.M.G. and D.D.T. return in BTD6, along with the new B.A.D. bloon. These bloons only appear in rounds 40+, however, they all have a lot of health. M.O.A.B.s require 200 hits to pop, B.F.B.s require 700 hits to pop, Z.O.M.G.s require 4,000 hits to pop, D.D.T.s require 400 hits to pop and B.A.D.s require 20,000 hits to pop, all gaining more health every round after round 80. After defeating round 100, players will receive an 'Insta-Monkey' which has the chance of already having upgrades that can be placed for free in any mode except for C.H.I.M.P.S. and challenges with no powers.


The only storyline of BTD6, upon playing a game account for the first time.

Upon playing the game for the first time, the Army Monkey gives a tutorial on how to play the game. At the track Town Center, he declares the aim of the game: "Stop the Bloons from getting through!" The player is then instructed to place a 0-0-0 Dart Monkey inside the designated circle. After placing a second 0-0-0 Dart Monkey in another part of the track, the first round can be played. The Army Monkey then points out the Play button, which is used to begin the next round.

After beating the second round, he points out that popping Bloons earns the monkeys experience: "Popping Bloons earns your Monkeys experience!" He then instructs the player to tap on the Dart Monkey icon to unlock an upgrade. He tells the player that "each Monkey type has 5 upgrades in 3 paths," after which the player is free to choose one of the Dart Monkey's Tier 1 upgrades to unlock.

After unlocking an upgrade, the Army Monkey tells the player that he needs to apply the upgrade to the Dart Monkeys in play in order for them to be able to use it.

After completing Round 3, Quincy, one of the ten current heroes, arrives. The Army Monkey tells the player that Quincy is a Monkey Hero that upgrades himself throughout the course of the game.

After Round 4 is completed, the player levels up to Level 2, allowing the player to unlock a Primary Monkey. The choices for them are Boomerang Monkey, Tack Shooter, Bomb Shooter, Ice Monkey, and Glue Gunner. The same process occurs after Round 9 is completed, which is when the player levels up to Level 3, allowing the player to unlock another Primary Monkey.

After Round 10, the player wins the tutorial game and earns BloonjaminsIcon.png 100.


All Monkeys in the game as of Version 22.0

Bloons Tower Defense 6 currently features a roster of 21 monkeys (2 new monkeys and 19 returning from previous BTD games) and 11 heroes to help pop bloons. These monkeys are split into four classes: Primary, Military, Magic, and Support. The monkeys range from simple Dart Monkeys to the all-powerful Super Monkey, each one with its own unique attacks, abilities, and strengths. Monkey XP still exists, but this time around it functions a bit differently. Players can save up Monkey XP to unlock upgrades in any order they wish, but the amount of monkey XP required increases the farther down the upgrade path they travel. XP can also be saved, allowing players to go down the path the player wishes rather than unlocking them in order. Each monkey has its own set of XP so they cannot use Dart Monkey XP to buy upgrades for the Bomb Shooter, for example. Several towers have been renamed from BTD5, namely Boomerang Monkey (from Boomerang Thrower), Wizard Monkey (from Monkey Apprentice), Bomb Shooter (from Bomb Tower), Ice Monkey (from Ice Tower), Mortar Monkey (from Mortar Tower), Dartling Gunner (from Dartling Gun), and Engineer Monkey (from Monkey Engineer).

Each monkey offers 15 total upgrades which are split into 3 paths of 5 upgrades where a player can get two paths: 1 path to tier 5 and another path to tier 2. If someone upgrades one path then another, the third path will be closed. Also, there can only be one of every fifth-tier upgrade on screen at all times (except for the Crossbow Master upgrade, with the monkey knowledge activated known as "Master Double Cross", one can have 2 Crossbow Masters in a game instead of 1).

There are currently 51 maps in Bloons Tower Defense 6. There are 17 beginner maps, 14 intermediate maps, 12 advanced maps, and 8 expert maps. The payout for completing a map depends on both the map's predetermined difficulty and the chosen game difficulty. After the first completion, the payout has a much smaller amount. (E.g. An Expert Map played on Hard difficulty will give more money than an Intermediate Map played on Easy)


  • Monkey Meadow: A grassy map. Similar to Monkey Lane from BTD5. This map contains no items blocking sight and no water, making it the simplest map in the game. In the 5.0 update, monkeys can be placed on the pumpkins at the top left and top right of the map despite the pumpkins being solid objects.
  • Tree Stump: A map around a tree stump. Bloons circle around the stump, then make a bigger circle before exiting. The tree stump will block the sight of towers, but towers on the stump have no restrictions. Similar to Park Path from BTD5. The axe in the log can be tapped to make it wiggle and the mushrooms can be tapped to make it glow and wiggle.
  • Town Center: A grassy map with a Bloons Monkey City vibe. Water lines the top left of the map, but is often too small and too far from the track to be useful unless using the Advanced Intel upgrade for the Monkey Sub. An additional option is to use Merchantmen as they generate money regardless of sight. There are crates near the building on the right that can be used for water towers before update 2.0.0. The buildings and the windmill are sight obstacles. This is the map featured in the tutorial of the game.
  • Skates: A map set on top of a frozen lake. Bloons travel across the lake in a series of three loops. The map features a large hole in the ice where water-based towers can be placed, as well as a group of cottages that can be removed to reveal a second hole in the ice for more water towers.
  • Lotus Island: An island in the middle of the sea, which has a few lotus plants and the remains of some sort of stone building. The Bloons travel around the perimeter of the island.
  • Candy Falls: A candy-filled map with a chocolate river flowing down the middle where water monkeys can be placed. The map is based on Willy Wonka's Chocolate Factory.
  • Winter Park: A snow-filled park area with a small fountain in the middle where water monkeys can be placed.
  • Carved: A track that resembles a Jack-O-Lantern.
  • Park Path: A clean, nice environmental, long and curvy track with water in a stream, returning from BTD 5. Sort of resembles a spiral.
  • Alpine Run: A snowy map based off of a ski lift.
  • Frozen Over: An icy themed map kind of resembling Ice Flow from BTD5 . The map features many triangles with lots of room for water towers.
  • In the Loop: An autumn-themed map. Bloons follow a square that has loops on 3 of its corners. There is water in the upper right loop. The trees and tools on this map can block a monkey's line of sight.
  • Cubism: An abstract art map. Bloons go around the triangles and quadrilaterals. There is water in the lower right corner and in one of the triangles, allowing for water towers to be placed on this map. This map features two storm drains that do not affect gameplay.
  • Four Circles: A sprint track map. Bloons go around four circles. The top left and bottom right circles are each half water. This map uniquely features a timer near the bottom right that counts minutes and seconds. It blocks monkeys' lines of sight as well.
  • Hedge: A grassy garden map. Bloons go around the hedges. There is a statue in the middle of a Dart Monkey. Hedges along the track block monkeys' lines of sight, and cannot be removed. If the Dart Monkey statue is tapped, it rotates 90 degrees.
  • End of the Road: A desert road map. Bloons follow a horizontal road with two curves and then go back where they came from. There is water near the end of the road, allowing for water towers to be placed. The cacti on this map can also block monkeys' lines of sight although this doesn't practically affect gameplay.
  • Logs: A swamp-like map. The bloons follow a vertical checkerboard path and then follow a horizontal one, going under numerous logs. The middle square of the checkerboard-like pattern is water instead of land, allowing water towers to be used on this map. Monkeys cannot see through the logs on this map.


  • Encrypted: A Halloween-themed map with multiple Bloon entrances. It takes place within a temple. The walls of the temple serve as line-of-sight obstructions. Outside the temple, there is a graveyard where towers of all kinds may be placed. Water-based towers may be placed on the waterlogged graves. Within the temple, there is a spot where towers of all kinds (except water-based ones) may be placed. Adjacent to the spot in the center, there are 4 pedestals covered by debris. The debris may be removed for $250 per pedestal. Each pedestal can only hold 2 towers that are within the specific tower type assigned to the individual pedestal. From left to right, top to bottom, the pedestals may house Magic, Support, Primary, and Military towers. Ninja Kiwi has stated that there is a secret hidden within the map; however, at the time of writing this the secret has yet to be found.
  • Bazaar: The second community-designed map added to the game, and takes place at a desert marketplace. Many line of sight obstacles such as the trees and central marketplaces appear on the map. Bloons come from alternating lanes from opposite sides.
  • Adora's Temple: A map that takes place on a temple with several fountains, multiple entrances and exits for Bloons, and layered steps to place towers on.
  • Spring Spring: A spring-themed map that features a center island with water surrounding. Bloons travel on two paths, with both paths having the same entrance and exit. There are no sight blockers in a practical sense (Rocks around the edge block sight, but not enough to matter).
  • Kartsndarts: A map that resembles a race track. The main track starts from the left, underneath the tunnel, around the second loop anticlockwise, around the first loop clockwise, above the tunnel and out through the right exit. There are two sets of hay bales and tires that lie in each circle, these can be removed for $500 each.
  • Moon Landing: A map that takes place on the moon. Bloons travel through a path that features three craters, which Bloons spin around in a spiral pattern before leaving. The rims of each crater rise high enough to block line-of-sight from most angles, making Mortar Monkeys ideal.
  • Haunted: A map that resembles the outside of a haunted house. Bloons come towards the house and come back to the entrance (resembling trick-or-treating). There are two trees next to the house that can be removed for $500 each.
  • Downstream: A map that takes place in a meadow, similar to Monkey Meadow. The bloons take two loops around the track. There is a large stream in the middle of the screen, hence the name. You cannot place towers in the middle of the loops until you clear the rock debris (each for $350). Added in 4.0 update.
  • Firing Range: A map that takes place in a firing range. The bloons move back and forth in the firing range itself and come down both sides to the exit. Towers cannot be placed in the sand of the firing range. There is a watchtower in the middle that blocks the vision of monkeys, but it can be removed for $1,000, along with a Ground Zero Bomber cinematic animation. Added in 2.0 update.
  • Cracked: A ruined land map. This map features a rock that can be removed for $1,000 but otherwise blocks a monkey's vision. Underneath the rock is a small body of water. Oddly, this map features a sign that can block towers from being placed on it but does not block the monkey's vision.
  • Streambed: A map that takes place in a dried-up streambed. There is a moderate-sized body of water near the bottom of the map. A fossilized skull in the middle of the map blocks line-of-sight, but can be removed.
  • Chutes: A temple map. Bloons come out starting on the left path, then alternating. There are two monkey statues in the middle, which you can remove for $350 each. Otherwise, they can block the sight of monkeys.
  • Rake: A cherry blossom/Japanese sand garden map. Bloons come out of two sides at once and leave in two places. This map contains a small body of water. There is also a statue that can be removed for $1,000, which will block the monkey's sight if not removed. Before the 4.0 update, it used to cost $350 to remove the statue. Oddly, the rake on the top left of the map does not block line of sight but does not count as viable land for placing towers.
  • Spice Islands: An island/archipelago map, consisting mostly of water. The palm trees can block a monkey's line of sight but can be removed for $1,000. This map was featured in a teaser to Bloons TD 6.


  • X Factor: A nature-themed map in the middle of a forest clearing, which has four paths which intersect in an X shape. Between rounds, the Bloons alternate which of the four paths they enter and exit from.
  • Mesa: A canyon map with two different pathways. Rocks can be removed for $500 each to place towers on the rock arches.
  • Geared: The first community-made map added to the game, it is a gear style map that monkeys spin around on a rotating gear that rotates every round. There are no obstacles on the map. Bloons go around the outer half of the gear.
  • Spillway: A toxic waste dump, filled with waste. Four walls can be removed for $2,000 each, which block water towers from shooting in the middle.
  • Cargo: A car filled lot of pavement with a ton of boats and water nearby to transfer cargo. After round 39, a new path opens up, which only M.O.A.B Class Bloons take, and two trucks that block vision can be removed for $500 each.
  • Pat's Pond: A swamp map with a large body of water in the center. Bloons travel on two paths, with the entrance of one being the exit of the other and vice versa. Two sets of trees and rocks can be removed for $500 each.
  • Peninsula: A rocky map that has water on three sides with few places to place towers. There are 3 rocks with debris on them, which can be cleaned of debris for $500 each. A large hill is also present that blocks sight. Towers can be placed on patches of grass.
  • High Finance: A city/construction map. Bloons will move first in an S-shape and then a U-shape around blocks of the construction area. A small bridge is present in the middle that allows water placement and early placement of towers similar to Cornfield. Each on the individual construction areas counts as sight blockers however they can be built up and towers may be placed on top to see over the other unbuilt areas. The cost to build each block ranges between $350 to $1,500. To build everything on this map it costs $12,550. Added in the 3.0 update.
  • Another Brick: A brick wall map. Bloons go around a wall, which counts as a sight blocker. The entire left side is off-limits for placing, but it is possible to remove each palette of bricks for $1,000 each to free up space for Banana Farms, Aces, Heli Pilots, Temples, Alchemists or anything that can bypass the line of sight. Small water puddles are present.
  • Off the Coast: A beach map. Bloons come from the water at the bottom to the beach and then go back to the water. This map features a wrecked ship in the water that blocks water towers from being placed on it, and cannot be removed. Land towers, however, can be placed on certain parts of the wreck, such as on the crow's nest and the bow.
  • Cornfield: A cornfield map. At the start, the only area where the player can place towers is a small square in the middle. The player may uncover more land by paying to remove the cornfields. The cost to remove a cornfield ranges from $350 to $1,500. It is possible to place towers within the dirt separating the cornfields if positioned correctly.
  • Underground: A cave-styled map. The bloons go around two rounded interlocking railroads. There are no objects that block the monkey's vision in a practical sense. (Rocks along the edges block vision, although this doesn't affect gameplay significantly.)


  • Flooded Valley: A map set at a dam. The track appears as though it is single-lane, but instead bloons come from both sides simultaneously and exit from opposite ends. The left-hand side is land that is heavily blocked by the extremely tall dam, while the right-hand side purely consists of water.
  • Infernal: A map set deep within a volcano. The track consists of two paths made of many small floating stones that interweave in the middle of the map; the entrances of these paths are on the left side of the screen, and the exits are on the right side. There are some small stone islands, two of which have water, on which you can place towers.
  • Bloody Puddles: A more difficult version of Muddy Puddles, featuring five paths instead of four to make it more difficult to deter the Bloons. There is also a broken-down jeep stuck in the mud, which can be removed for $1000. However, paying to remove it instead triggers a gag where the Chinook that shows up to remove the jeep breaks down and falls, taking up even more space. After this, the Chinook, jeep, and nearby stones can all be removed for a single purchase of $500.
  • Workshop: A map based in a factory setting. Many tables block vision, and the path is very short. After round 39, a new path opens up, which only M.O.A.B Class Bloons take. Two machines can be activated for free the first time you use them, with one making the main path longer and the other slowing bloons, and will deactivate after a certain time. However, reactivating them costs a steadily increasing price.
  • Quad: A grassy map with four entrances/exits for bloons. Four floral trusses blocking near each entrance/exit can be removed for $1500 each. A pond in the middle allows for the placement of water towers.
  • Dark Castle: A castle themed map kind of resembling the map Siege from BTD5. There are four entrances and one exit. Towers can be placed on top of the castle in a small place, but other places will block their sight. There are trees blocking sight of incoming bloons until 3/4 of the map, but these three trees can be removed for $1000.
  • Muddy Puddles: A muddy field map. Bloons come out of the four squiggling paths, alternating each round. Puddles are present between some of the paths allowing Buccaneers and Subs to be placed.
  • #Ouch: A city or road map. Bloons come out four ways and leave four ways, all at the same time. The water in the middle can be removed for $1,000, but cannot be removed if towers are placed in the water. This map is similar to the Extreme Map Main Street featured in BTD5, albeit with more accessible water and another set of paths. This is also very similar to Phase Crystal in Bloons Monkey City.

Game Modes

There are a total of 17 different game modes in BTD6, all of which are accessible in different categories of difficulty per map: Easy, Medium, and Hard.

Main article: Co-Op Mode (BTD6)

Co-Op Mode has been first introduced to BTD6 in Version 11.0. Co-Op can be played with 2-4 players per game. Unlike BTD5, there are a number of maps where space is shared universally among all players, particularly on maps where placeable land is insufficient when divided. Just like in BTD5, players can exchange income with each other along with requesting for income.

Custom Challenges

Main article: Challenge Editor

Challenge Editor is used to make various challenges in BTD6. In Challenge Editor, players can set the map, difficulty, starting cash, lives, rounds, and other special parameters to increase the overall complexity of the challenge. For instance, the health and speed of regular bloons and MOAB-class can be increased or decreased, certain towers and/or upgrades may be restricted, certain quantities of towers may also be restricted, and certain CHIMPS rules (i.e. in this case, Continues, Hearts Lost, Monkey Knowledge, Powers, Selling, but not Income) may be implemented too. Additionally, the player may set all regular bloons to become Regrowth and/or Camo.

Players may share their challenge code of their challenge once it is completed without the use of Powers. Players may also send their challenge to Ninja Kiwi once they have successfully completed the challenge, along with indicating their identified difficulty rating (Easy, Medium, Hard, Friday Stinger).

In Version 22.0, a challenge browser was added in-game along with the ability to like and favorite challenges. Regrow Rate was also added as a new slider option.

Balance changes

Main article: Bloons Tower Defense 6/Balance changes

There were various balance changes occurring on each update, adjusting a variety of different towers towards a relatively equal power for their own unique special fields of expertise.

For the most part, many of the balance changes in the game each update were designed to reduce the overpoweredness of certain towers and/or their combos, while at the same time allowing certain other towers and their upgrades to become more usable choices in certain scenarios. For certain upgrades, crosspathing interactions have also been adjusted in certain updates to balance out the overall power for the alternate crosspathing ends for different scenarios, such for the Crossbow Master, where Path 1 crosspaths granted even more pierce bonuses in exchange for Path 2's plain bonus attack speed.


Bloons Tower Defense 6 was announced on March 28, 2017 on PRLog for the iTunes App Store, Google Play Store, and Amazon App Store and released on June 13, 2018. What's Up At Ninja Kiwi? - 27 October, 2017 The game, like its predecessors, revolves around popping Bloons using monkey towers. Unlike the previous games, however, Bloons Tower Defense 6 utilizes 3D graphics to enhance visual gameplay. The game also utilizes a new feature called Line of Sight, a feature where certain obstacles can block the monkey's line of sight, which makes tower placement significantly more important. Certain vision-blocking objects can be removed for a fee, which will free up space for tower placement and sometimes can add other gameplay effects such as revealing hidden water.

On December 17th, 2018, BTD6 Steam for Windows was released worldwide, initially released with Version 7.0. BTD6 Steam for Macintosh was released worldwide much later on, starting from 12th March 2020 with the release of Version 16.2.

On January 25th, 2019, BTD6 Steam for Windows got 10 Trading Cards in the Steam Community Market.

  • Ninja Kiwi said they would officially release Bloons Tower Defense 6 on 14th June 2018, but it was instead released a day early, on 13th June 2018. This is probably because the mentioned date was the release date in New Zealand time, which is very close to the International Dateline.
  • As of 6/15/18, Bloons TD 6 was the number one paid app on the Appstore and Google Play Store. Similarly, Bloons TD 5 previously made it to the top few games on the Appstore and Google Play Store, and still holds a high rank in both stores.

  • In BTD6, the pop count is now replaced with a damage count which will increase with each hit rather than each pop, including the RBE of MOAB-Class Bloons.
    • Banana Farms also have a pop count that is equal to the amount of money they have produced. This is the same with Merchantmen, and along with all other monkeys that primarily produce money.
      • As of the 5.0 update, Towers that produce money will now have a banana symbol for their cash count instead of the default one.

  • Towers in BTD6 have a total of 15 upgrades to choose from (3 paths of 5). which is almost twice as many upgrades per tower BTD5 had to offer (8 upgrades among 2 paths of 4).
    • However, each monkey can only have a maximum of 7 upgrades purchased, up only 1 from the 6 upgrades in BTD5. This is only for the 1 tier-5 tower on screen; all other towers can purchase only 6 upgrades
    • This is possibly to prevent monkeys from being too powerful and the game being too easy, as crossing all 3 upgrade paths can result in drastically improved damage output.

  • The tower stacking glitch that BTD5 Players used to exploit using Support Chinook no longer works in BTD6 even since the initial release.
  • BTD6 Steam for Mac came out over a year before BTD6 Steam for Windows, even though Bloons Adventure Time TD Steam supported Macintosh ever since the Steam version's original release date.
  • BTD6 was free to purchase for the first time on 22nd/23rd May 2019.
  • On September 11th/12th 2019, one day after the BTD6 community discovered that display text could be attributed with textual code (e.g. <color=blue> or <size=200>), Ninja Kiwi announced that they will ban players who use such exploited coding onto their display username if detected on public Co-Op matches or on public leaderboards (i.e. Race Events, as there aren't any other public leaderboards of that date). This post can be featured here. This ban announcement did not affect Custom Challenges.
  • Up to 14 characters may be used for the display username.
  • On mobile devices, attempting to play music from an external app such as the built-in iOS's Music app while the game music plays will cause both the music from the app and the game to play simultaneously. However, starting the music before the BTD6 app loads will cause the music to override both the music and the sound effects.
  • As of Version 21.0, the name of the game over message was changed from "Defeat" to "Game Over", but only for losing after initially winning.
  • On the date 21st January 2021 on 9:58am NZDT, 6,073,283,850,717 Monkey Money was earned in total, and 80,302,074 Insta Monkeys collected, and 3,138,290 players have been defeated by Round 90 (assuming normal games, that is).
