In StickWars, the player defends a fortress from invading hordes. In order to do this, the player uses the touch screen of the iPhone or iPod Touch to pick up invading stick figures and toss them high enough in the air so that they will die when they fall back to earth. Doing so rewards the player with cash which earns interest when it sits in the bank, or can be spent on fortress wall repairs, maintenance, or upgrades. The money can also purchase other things such as prisons which will hold invaders until such time that they decide to become part of your army.
As the game progresses, the player can train archers and wizards to more effectively repel invaders and build a variety of more effective counter-measures in a continuing arms race.
