great game!  this is the second "cooperative" game we've gotten and we are really liking them.  this one is a matching game, with the pieces being different valuable items, jewelry, golden goblet, painting, etc.  you blindly pick out 3 pieces and slide them behind the secret door.  then you take turns flipping pieces over to try finding matches. when you flip a piece over, its either a valuable item or a clock. if its an item, you flip another piece over to try to find its match. if its a clock, it goes up along the top of the board - once you get a certain amount of clocks, 12 I think, you lose the game, time has run out. the point of the game is to figure out which 3 valuable items have been hidden behind the secret door, by flipping pieces over and figuring out which ones you don't have a match for.  we've played the game probably 6 times and have only won it - figuring out what the 3 pieces are before we flipped over all the clocks - once. its fun though. and its cooperative, so you can help each other remember what item is where. my 7yr old son and I love playing it.
