Vertigo

Vertigo is an abstract game with unusual equipment. Players place pieces into an upright Plexiglas disk which turns inside a frame. The pieces can fall out the bottom of the disk, but on which side they fall is controlled by switches and blocking pins. On a turn a player can add a piece to the disk, turn the disk, flip a switch, or move a blocking pin. The object is to get six pieces to fall on your side.
