Story: The three ??? kids find 16 burglar-proof doors in a castle. What might be hidden behind them? With luck and combination, the players are able to open the doors, and find a treasure map. Who will get moist coins from the treasure chest?
The playing area consists of 16 cardboard doors. Each one gets a cardboard "lock" attached randomly, which shows tree colored dots. The player in turn tries to open one of the locks by rolling 3 color dice. If necessary, he may re-roll some or all dice up to two times. In addition, one die shows some sides that act as wild card, or hurt the leader.
If the player matches the colors of a lock, he turns over that door. The back shows a part of the treasure map, along with 1-3 coins, which he collects. Goal is to have most coins at game end, when all doors are opened and the map is complete.
