List of themes

Icon	Name / description	Effect	Research required
	Cluster Chaos Send tightly clustered groups when possible.	Grouped Bloons are significantly more common and packed MOABs and BFBs can appear. This has the side effect of reducing the overall duration of rounds, speeding up the attack considerably.	—
	Round Ramp Bloons come weakest to strongest	All Bloon groups are arranged in order of their rank (i.e. the order in which Bloons are prioritized by Strong targeting). Stronger Bloons are slightly more numerous.	—
	Fast and Furious Speed over toughness	Packs of Yellow Bloons and Pink Bloons replace other Bloons, even on MOAB rounds, where they can replace Rainbow Bloons and Ceramic Bloons. Bloon groups are arranged in order of their rank like in Round Ramp, groups are marginally tighter, Lead Bloons are rare, and packed MOABs can appear.	Fast Bloons
	Hard and Heavy Extra leads and ceramics	Lead Bloons and Ceramic Bloons are significantly more common. Lead Bloons can appear as early as round 1 and Ceramic Bloons can appear as early as round 3.	Heavy Bloon Armor
	Cash Starve Less RBE for a few rounds, then regular afterwards	Reduces the RBE of early rounds slightly.	Heavy Bloon Armor
	Regrow Rush of Death Tightly spaced regrow bloons	Regrow Bloons are significantly more common and can appear as early as round 1 instead of round 3.	Rubber Repair
	Camo Craziness High % of camo bloons	Camo Bloons are significantly more common and can appear as early as round 1 instead of round 6. Camo Bloons cannot appear once MOABs can start spawning, as normal.	Camo Modification Tech
	Sneaky Camo All bloons are non-camo except for a few rounds throughout	All Bloons are converted to Camo Bloons on every 10th round (7th round if extra strong), even on MOAB rounds. Camo Bloons do not appear at all on other rounds.	Camo Modification Tech
	Camo Regrow Pain Send as many camo regrow bloons as possible	Increases the odds of Camo Bloons, then converts all Camo Bloons to Camo Regrow Bloons. Since Camo Bloons stop appearing once MOABs can start spawning, this has no effect on later rounds.	Camo Modification Tech
	MOAB Push Sends a MOAB as early as possible	MOABs can start spawning one round earlier (up to four rounds earlier if extra strong, depending on difficulty). Rounds that can spawn MOABs use different generation mechanics, so on the affected rounds, Rainbow Bloons and Ceramic Bloons are more common and Camo Bloons cannot appear.	MOABs
	ZOMG Zuprise Send a single ZOMG as a suprise on an earlier round	Adds one ZOMG to the start of the last round (second-to-last round if extra strong).	ZOMGs

Defending

When a player receives an attack, it is initiated as soon as the game is able to connect to the internet. Once the attack initiates, the player has 24 hours to defend it, otherwise it automatically ends in a loss for the player and a win for the opponent the next time the game connects to the internet. Attacks cannot be defended against without an internet connection.

Attacks occupy unclaimed tiles within range of the player's city. Attacks cannot occupy Volcano Terrain tiles, Cave Terrain tiles, Special Terrain tiles, or tiles containing a treasure chest. Attacks use the same tracks as their original tiles, but override their difficulty levels, modifiers, and rounds. When defending an attack, each round begins immediately after all Bloons from the previous round have entered instead of waiting for them to be popped first, similar to Apopalypse mode from Bloons TD 5. Unlike Apopalypse, end-of-round cash is still given.

Pacifist Mode

Pacifist Mode prevents the player from receiving attacks from other players. It can only be enabled if the player has not sent an attack in the last 72 hours, and it is automatically disabled if the player sends an attack afterwards. Additionally, in the Flash version only, Pacifist Mode cannot be enabled if the player has 1000 or more City Honor.
