Alternate Bloons Rounds[fn 1] (often abbreviated as ABR) is a game mode in Bloons TD 6. In standard play, it is played on Hard difficulty. This helps redesigns the first 140 rounds to be much difficult, generally by introducing strong Bloon types earlier and having rounds with Bloon Mods such as Camo Bloons. After round 140, the game changes to freeplay round generation with no alterations. Since the mode is normally played on Hard difficulty, rounds 1 and 2 are skipped by default and the player wins after completing round 80; rounds 81-150 are optional and rounds 1 and 2 can only be seen in other modes such as the Challenge Editor.

Rounds 101-140 do not exist in the console version due to it being based on an older version.

Strategy

For more in-depth strategies, see Strategy:Alternate Bloons Rounds.

Alternate Bloons Rounds has greatly increased difficulty compared to Hard Standard. More challenging Bloon types with extra immunities, such as Camos, Leads, Purples, all appear earlier. In addition, many rounds are greatly increased in difficulty, such as Round 40 having a Fortified MOAB. Therefore, defenses should be well-equipped for all Bloon types and be able to defend more than in Hard Standard. Some progression in obtaining Monkey Knowledge is recommended before attempting Alternate Bloons Rounds.
