Buying without a role
A tower should solve a problem: early popping, grouped enemies, tougher targets, camo, lead, range, or cleanup. Random upgrades can leave a defense strong in one area and weak everywhere else.
Ignoring the map
Corners, loops, and long straight paths change which towers are valuable. Good placement often matters as much as the tower choice itself.
Overcorrecting
Beginners often lose to one wave, then spend too much fixing only that problem. A better habit is to keep the whole defense balanced while covering the weakness that caused the leak.

No. Phase 1 avoids patch-sensitive map and boss guides. This page focuses on general beginner habits.
What is the biggest BTD6 beginner mistake?
The biggest mistake is building towers without knowing which enemy or wave problem they are meant to solve.
