Quicksand is a deep brain-burning abstract for two players, played on a set of Martian Coasters. On your turn, you can either place a pyramid onto the board, or use a placed pyramid to capture other pyramids by jumping over them. After that, you MUST rotate one of the coasters, creating a volatile board that can radically swing the balance of power. The first player to capture 15 points of opposing pyramids is the winner.
