Get Notified How to Play

Three things stand between you and defeat

01

Build Your Maze

Place towers freely on the battlefield. Every tower also acts as a wall. shape the enemy's path into a lethal gauntlet. No two mazes are ever the same.

02 3

Play Your Cards

A deck of spell cards gives you tactical options every wave. rain fire on the path, buff your towers, slow enemies, or generate gold. Spend mana wisely.

03

Defend to the End

Enemies pour in wave after wave. If they reach the castle, you lose HP. Run out and the keep falls. Solo, co-op, or PvP. the castle is always at stake.
