BTD6 bloon reference

Bloon types are really checks your defense must pass

Normal layers ask for enough popping. Properties ask for detection or damage type. MOAB-class threats ask for health, speed, control, and cleanup.

Quick answer: how BTD6 bloon types work

BTD6 bloon types fall into three practical groups. Normal bloon layers ask whether your defense has enough popping power and cleanup. Special layers and properties ask for a specific rule, such as camo detection, lead-popping damage, purple-safe damage, regrow control, or fortified health. MOAB-class threats ask for a different kind of plan because they carry far more health and often need focused damage, slowing, or backline cleanup. When a bloon leaks, identify the check first: visibility, damage type, speed, health, or a combination such as camo lead or DDT.
