The Tower starts out at 2.5 ft tall and can grow to over 5 ft during games. This set includes printed numbers on the bottoms of some of the blocks with a corresponding custom rules sheet. The rules sheet is a dry-erase board so you can create your own rules such as- skip your next turn / reverse order / draw another block / etc. You can make the rules adult-themed or even goofier. Included with this game are 54 wooden blocks (each block measures 7.2 x 2.4 x 1.5 inches) and a dry erase board. Rent for $15 for the entire weekend.
