Android Nim is a game written by Leo Christopherson for the TRS-80 computer in 1978. A version for the Commodore PET by Don Dennis was released July 1979. A new version rewritten for Microsoft Windows was released in 2005. The object of the game is to remove the last android from three rows of androids. The game's premise is simple, but its animation is impressive given the limitations of the TRS-80's display. Throughout the game androids are animated to face different directions, as if bored or engaging in conversation with one another. If the human wins, the computer is an amusingly poor sport and displays astonishment; if it wins, the computer displays a huge "I WIN!" message. If the computer is about to lose, it pretends to seek futile ways to avoid losing (i.e., by selecting more androids than are available in a given row) before giving up.
