Put your nerve, wits and agility to the test with the Stacking Tower Stand-Off that ups the ante on your favorite block-toppling party game. You and your opponents take turns removing blocks from the 20-inch tower, but beware of the challenges hidden on 20 of the game pieces! You may have to win a thumb war, hold a 30-second plank or balance a block on your palm while removing another one from the tower. Will you keep your hands steady and your focus sharp, or will you be the one to bring the tower crashing down?
