Players are knights on their way to a castle where a princess and a treasure awaits them. To get there they have to cross a "wobbly bridge" (Wackelbrücke). The bridge consists of several tiles which rest on two pillars each. Two dragons dwell in the river beneath the bridge. Every now and then (determined by a dice roll) the dragons bump into the pillars causing them to collapse. Thus, more and more bridge tiles will become unstable and players have to carefully choose their path across the bridge.
