About HamSumo
HamSumo is a physics-based multiplayer game where up to four players battle as hamsters in an arena. Choose from eight playable fighters, each with a distinct look and personality, and use their moves and physics-based movement to outplay opponents.
Versus matches
You can face friends or CPU opponents in Versus mode, either in 1v1 duels or a four-player Free For All. Each hamster has three unique Star Moves, which you can learn to use to turn the tables. Movement is easy to learn but takes practice to master.
Adventure mode
In Adventure mode, you follow Captain Ham's perilous journey to Planet Sumo. A new chapter is available every week.
