Forbidden Bridge is a board game which simulates being a treasure hunter. Players play as explorers who are after ancient jewels, which are guarded by an angry spirit. Occasionally, the bridge guard will awaken and (via a motorized mechanism powered by the player pushing his head down) shake the bridge, which can cause players' pieces to fall off. Players also can get the chance to "steal" another player's jewel. The first player to retrieve three jewels and return them all in their boat wins.
