Stick Fight: The Game is a vicious fighting game depicted with stick men. You play by controlling small coloured stick men, who mimic real-world physics and bodily movement. To win you need to use the physics-based movement to land punches, kicks and use weapons to kill the other players.

Play involves taking on up to four other people in rapid fights to the death. Although the controls are simple, it takes considerable time (and patience) to master how to get around. Even when you do, the frantic pace of the fights can still mean that you miss jumps and punches or simply fall to your death.

The game is played in a randomly chosen level. These often include hazards and weapons that add new ways to dispatch other players. Some levels are fragile or constructed from collapsible boxes. There are also some special levels where one player can become a boss character for the others to team up against.
