the player must try to defend his castle from enemy troops while simultaneously trying to destroy the opponents castle with their own troops. The player has two general means of defending and attacking. Units can be purchased that will walk towards the enemy's castle attacking anything that comes into their path, or fire projectiles from on top of the castle's walls. Various projectiles and units can be unlocked in the course of the game with gold earned with defeating the enemy. Firing projectiles can be done either by manually flexing the string of the bow using a swipe movement, by tapping the targets or set to automatic.
The game comes with four different difficulties, six different troop types and eight weapons.
