Whatever you do, don't let the tower fall! Stack the Kinderfeets Giant Stackers on top of one another to create a giant tower (each layer should consist of 3 blocks, with each new layer turned 90 degrees from the one below it). Take turns pulling out one block at a time and stacking them back on the top of the tower to create new layers. (Customize the game by creating your own rules using the blocks' engraved numbers 1-18!) Keep playing until one unlucky player knocks the structure down.
