Co-op (BTD6)
Co-op is a multiplayer mode in Bloons TD 6, introduced in version 11.0 and unlocked at level 20. It allows two to four players to play in a single game simultaneously. All versions support online play using a peer-to-peer connection,[1] and the console version also supports local Co-op. Players can either share the entire map or have their own dedicated sections of the map to place and upgrade their towers in. Each player has their own Hero and tier 5 upgrades, though they have to share Hero XP and cash earned from popping Bloons and at the end of each round. Playing in online Co-op earns separate medals from singleplayer, and there are some events that are playable in Co-op.
Mechanics
In a Co-op game, all players play together on a single map with the same pool of lives. Depending on the configuration, the map can be split into multiple sections for each player, or allow all players to place anywhere. Each player can place their own towers and powers and cannot control towers placed by others. In online Co-op, there is a delay between a player inputting an action (such as placing or upgrading a tower) and the action occurring, to allow all players' clients time to sync with each other. Each player has access to their own Hero, tier 5 upgrades, and pool of cash, though some forms of income are split among players. While this allows for multiple Heroes and multiple copies of tier 5 upgrades, the game does not allow multiple copies of Paragons or the VTSG. If playing in a mode with challenge rules, any restrictions on the number of towers will count all players' towers.
The way unlockable features function in Co-op varies:
- Towers and upgrades are only purchasable by players that have unlocked them.
- Monkey Knowledge upgrades apply to all players, even to those who have not unlocked them yet, if at least one player has them unlocked.
- Fast Track Mode applies if at least one player has it enabled.[2]
On the victory screen, every player can receive a different callout based on their actions in the game. Two players cannot receive the same callout.
Ownership
|
This article is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: If a player quits, how is ownership of their towers distributed? |
If a player places a tower or uses a power, that player becomes its "owner". Players cannot upgrade, sell, activate the abilities of, or change the targeting options of towers they do not own. For the most part, towers and powers can still interact with towers owned by other players, including providing buffs to them (e.g. Monkey Villages, Alchemists, or Overclock), contributing to Jungle's Bounty, acting as platforms (e.g. Portable Lakes, Carrier Flagship, and Lord of the Abyss), and sacrificing them (e.g. Sun Temples, True Sun Gods, and Paragons). There are a few exceptions:
- Support Chinooks and Special Poperations cannot reposition or use
Door Gunner on towers owned by other players. - Monkeyopolis cannot absorb Banana Farms owned by other players.
- Adora cannot Blood Sacrifice towers owned by other players.
- Tech Bots cannot be linked to towers owned by other players.
Emergency Unlock only appears for players that have a Dartling Gunner, and using it does not change the targeting of other player's Dartling Gunners.
Come On Everybody!'s conditions are separate for each player; a player's Primary towers gain a buff depending on the tiers of all Primary towers owned by the same player, ignoring other players' Primary towers.
Paragon of Power's conditions are separate for each player; a player's Paragons gain the buff if the owner does not own any tier 5 towers of the same type, ignoring other players' tier 5 towers.
If a player leaves the game, ownership of their towers is distributed to other players.
Map splits
Co-op matches can split maps into different sections for each player. Players can only place towers in a section they own or in a free-for-all section, but towers can place sub-towers in sections not owned by their owner. Each map has a default split setting, but the host can change it to any split before starting the game. In the free-for-all split, all players can place anywhere on the map, which is the default for all Expert maps. All other splits have two sections if there are two players or four sections if there are three or four players, and the fourth section becomes a free-for-all section if there are only three players. If a player leaves the game, their section becomes a free-for-all section.
Controls
- Any player can start rounds and toggle Fast Forward.
- Auto Start applies if at least one player has enabled it.
- Menus and pop-ups do not pause the game.
- Players cannot save Co-op games, nor can they restart outside of a game over.
- On a game over, any player can restart the game or use a continue. On a victory, any player can start freeplay mode. There is a grace period between the victory and game over screens appearing where the restart, continue, and freeplay options are not selectable, which allows players to quit before another player performs that action.
- The player who created the game is the host, indicated by a blue pip next to the player icon in the sidebar for sending and requesting cash. If the host disconnects, the game selects a new host for the match. If the former host reconnects, they do not become the host again unless the current host disconnects and the game selects the former host.
- A player can press the "mute" button next to a player's icon in the sidebar to hide emotes and cash requests from them.
Cash distribution
Each player starts with the default starting cash of the selected mode minus $50 per player in the match, except in Deflation mode, Boss Bloon Events, Boss Challenge, or the Co-op Daily Challenge, which instead splits the starting cash evenly among all players. The extra cash from 
More Cash is also distributed evenly among all players, provided at least one player has it enabled. All cash earned from popping Bloon layers, and at the end of each round, is split evenly among all players. Double Cash Mode only doubles the starting cash and cash per pop for players that have it enabled.
Cash generated by towers and powers only goes towards the owner, with a few exceptions:
- Effects that increase cash per pop distribute the additional cash among all players. This includes Monkey Town's buff, Pirate Lord's ability, and Rubber to Gold's golden Bloons.
- Bloon Traps and XXXL Traps distribute half of the cash they generate among all players (i.e. the amount that would have been gained by popping the Bloons outside of a trap). The other half all goes to the owner.
- Benjamin's Skimming is distributed among all players.
Sending cash
Each player can send cash to another player or request cash from another player, except in Deflation mode. The amount of cash sent by pressing the send button depends on the amount of cash the player currently has:
- With $500 or more, the player will send 20% of their current cash, rounded down.
- With $100 or more, but less than $500, the player will send $100.
- With less than $100, the player will send all the cash they have.
Experience
- All players earn the same amount of experience for their player level that they would earn in singleplayer.
- Tower XP at the end of each round is distributed among players based on the ratio of cash they have invested into their towers and upgrades relative to the total cash invested into towers and upgrades by all players. For example, if player 1 has invested $400 into towers and upgrades and player 2 has invested $600 into towers and upgrades, then player 1's towers will receive 40% of the tower XP at the end of each round and player 2's towers will receive the other 60%. For each player, this XP is further distributed among their towers based on the cash invested into each tower type, in the same way as in singleplayer.
- If multiple Heroes are on the map at the same time, the XP is distributed among them evenly.
Cosmetic items
- Place FX, Upgrade FX, Pets, Projectiles, Flags, and Power Skins only apply to the player that has them equipped.
- Pop FX and Bloon Skins alternate between each player's selected item, including having no item selected.
- Monkey Names are visible to other players.
- Cosmetic extras and Music Tracks are separate for each player's view of the game and cannot be seen or heard by other players.
Emotes
Emotes are a system players can use to communicate with each other. Players can mute other players to avoid seeing their emotes. Emotes are split into four sub-categories:
- Standard Emotes: display an animated icon above the icon of the player that used it.
- Text Emotes: display a string of text that depends on the language of the players viewing it.
- Sound Emotes: trigger an icon and a sound effect.
- Fullscreen Emotes: display a visual effect that covers the entire screen.
Some emotes are unlocked by default, and others are unlockable by purchasing them from the Trophy Store.
Matchmaking
Bloons TD 6, Bloons TD 6+, and Bloons TD 6 NETFLIX players can play together, though names of players on different platforms are hidden from each other (for example, Bloons TD 6+ players can see each others' names, but they cannot see Bloons TD 6 or Bloons TD 6 NETFLIX players' names, and vice versa). The Chinese version and console version have separate matchmaking and cannot match with players from other platforms.
Quick Match
Quick Match allows the player to join any publicly-hosted game that fits within one of three constraints the player can choose from. If no match is found, the game creates a match with a random map (using its default map split), difficulty, and mode within the constraints. When creating a match, the game can select maps the host has not unlocked yet.
| Constraint | Map difficulty | Game difficulty | Game mode |
|---|---|---|---|
 Any Game |
Any map | Any difficulty | Any mode |
 Medium Game |
|||
 Long Game |
Create Match
Create Match allows the player to host a match with a selected map, map split, difficulty, mode, and number of players. The host cannot select maps they have not unlocked yet, nor can they select Blons, Protect The Yacht, or Map Editor maps. Matches are private by default, but the host can make them public to allow Quick Match players to join. The host can also invite players on their friends list to join the lobby.
Join Match
Join Match allows the player to enter a public or private match by using a code or by searching for games hosted on the same Wi-Fi network.
Modes
Co-op supports the same game modes as offline singleplayer, except Sandbox. Unlike in singleplayer, all modes are accessible without requiring players to complete prerequisite modes first.
Local co-op
Exclusive to the console version of Bloons TD 6, local Co-op is playable by connecting additional controllers to the console. In local Co-op, there is no delay between player inputs and in-game actions occurring (such as placing and upgrading towers). Despite being hosted on one system, local co-op games still cannot be paused or saved. Playing in local co-op earns singleplayer medals instead of co-op medals.
Boss Challenge
Boss Challenge supports Co-op play with the same Normal, Elite, and Battle modes as in singleplayer. Each mode tracks separate high scores for 1-player, 2-player, 3-player, and 4-player games. This is the only way to play Blons and Protect The Yacht in Co-op outside of the occasional events that use them.
Events
Several events support co-op or have separate modes for co-op.
- Co-op Daily Challenges are biweekly Daily Challenges that can only be played in Co-op. In addition to the usual Daily Challenge parameters, Co-op Daily Challenges set the number of players required and the map split.
- Collection Event rewards are also given in Co-op games. Bonus rewards apply if the host selects a map that has a bonus on their account.
- Monkey Teams events are playable in Co-op if the host selects a map that it is currently active on for their account. All players must use the allowed towers to earn the extra Monkey Money.
- Golden Bloon events are playable in Co-op if the host selects a map that it is currently active on for their account. All players earn the same rewards for popping the Golden Bloon, regardless of if they contributed to popping it or not.
- Boss Bloon Events have separate leaderboards for 2-player, 3-player, and 4-player games in both Normal and Elite mode.
Rewards
Monkey Money
Co-op rewards the same amount of Monkey Money as playing in singleplayer, though there is no bonus Monkey Money for earning a new medal. Bloons TD 6+ and Bloons TD 6 NETFLIX players earn 50% more Monkey Money, which is not shared with Bloons TD 6 players.
Due to a bug, the Co-op lobby does not display the Monkey Money reward with 
Mo' Monkey Money applied, but all players do earn the extra Monkey Money as long as at least one player has it.

Medals
Co-op medals function mostly the same as the solo medals. The red CHIMPS medal is earned if the player quits and re-joins the game later; this doesn't affect the type of CHIMPS medal the other participants earn, so it's possible for players to get different CHIMPS medals from each other even if they played the same match.
