The set of 57 solid wood bricks is sanded and smoothed and allows the pieces to slide against each other easily. The set-up starts out at 38 in. tall and can stack to over 6 ft. during play. This classic game is perfect for game nights, teen/adult parties, company picnics/ team building exercises or even your local neighborhood block party. But, be careful you are not the one to make the tower come crashing down!
