Hamsterball is a video game developed by Raptisoft Games, released on 8 February 2004 for Microsoft Windows. The TikGames PlayStation version was created on 25 March 2010. Similar to the arcade game Marble Madness, the goal is to complete a series of race courses in as short a time as possible while avoiding various obstacles. Instead of a marble, however, the player controls a hamster in a clear plastic exercise ball. A set amount of extra time is added to the player's clock at the beginning of each race; if time runs out, the game ends.
