In Circle Defense, waves of enemies never stop coming. Your job? Choose the right units, upgrade them, and watch your army fight to protect the circle at the center of the battlefield.

1. Defend Without Limits
Enemies will attack from all sides, but your army fights back on its own moving and attacking intelligently to hold the line. All you need to do is select the best units and keep upgrading them for maximum strength.

2. Upgrade and Grow Stronger
Earn crowns with every run and invest them in permanent upgrades. Improve your army’s power, speed, and spawn rates in the workshop and research center. The stronger your upgrades, the further you’ll go.
