Spinimax is a three-player game for the Shibumi set. The board starts empty. Players take turns adding a piece of their colour to an empty board cell. Whenever a 2x2 platform is formed, at any level, then a piece is placed on top, its colour being the minority colour in the 2x2 platform (if any) otherwise the majority colour. The winner is the owner of the piece placed at the apex of the pyramid on the final move.
