FAQ

What is the best Build a Tower Defense code?

1KCCU for the Mythic Sonic Cannon — mythic towers deal far more damage than regular ones and carry early waves on their own.

What do potions do in Build a Tower Defense?

Damage Potions boost every placed tower's attack; Luck Potions improve boss reward rolls; Gold Potions add cash for the upgrade tree — best saved for endless mode.

Where do new codes come from?
