Icehouse (game)
Icehouse is a turnless abstract strategy game invented by Andrew Looney and John Cooper. It was the first of many games played with Icehouse pieces.
Andrew Looney came up with the idea for a game played with pyramids in a series of science fiction short stories he was writing; several of the characters were obsessed with playing the game of Icehouse which had been recovered from the long-dead Martian civilization. John Cooper created the rules to make the game playable in real life.
