Map difficulty (BTD6)

Map difficulty is a categorization of the maps in Bloons TD 6 roughly corresponding to the maps' difficulty. The map difficulties are, from lowest to highest difficulty: Beginner, Intermediate, Advanced, and Expert.

The higher the difficulty of a map, the more likely it is to contain features such as short paths, multiple paths, line of sight and placement blockers, removable objects, and unique gimmicks to make the map more challenging.

Effects on gameplay

The difficulty of a map impacts gameplay in several ways.

Monkey Money
