Building towers, or rather build one tower by a joint effort. Who manages to place the roof or place the last block? The game is directed by cards. On a square basis area the triangular basis block is set up. The cards are stacked. In your turn you reveal the top building card - the cards determine which block must be placed with which hand. There are also cards offering free choice or change of turn order or cards demanding placement of a roof. If you can place a roof or the last block without tumbling the tower you receive a chip. If you collect three chips you win the game.
