Tower Guard

Enemies march down the road towards your castle. Build towers on the grass beside the road, upgrade them, and stop every wave before it gets through. Each level has its own road and its own waves, and every 5th level ends with a boss.

There are 5 towers to unlock: Blaster for steady shots, Cannon for groups, Frost to slow enemies down, Laser that burns through armour, and Tesla that chains lightning between enemies. Win up to 3 stars per level, spend your coins in the shop on more starting gold, stronger towers and thicker castle walls, and finish the daily missions. Easy, Normal and Hard change how tough the enemies are and how many hearts your castle has.
