Players each have one or two pawns. Depending on a dice roll they chose which pawn to advance along the spiral. Pawns landing on or adjacent to their own colour advance forward or backward along the spiral, or move inward or outward. If you and on another pawn the other pawn moves backwards five spaces, but may then in turn trigger off backward, forward, inward or outward movements. A quick, fun family game reminiscent to Clue (Cluedo), which offers some interesting tactical decisions.
