This Hammer Crown brand Giant Tumble Tower is truly a work of art and, even better, a wonderfully fun game to play. Stack a 19-level tower that measures 34in/86cm tall and 8.25in/21cm square from the 57 pine blocks included in this game. To play, stack 3 blocks in each direction, leaving the lower center free. Stack the tumble tower straight and even. Each time you pull out a block it must be stacked on top of the tower in an orderly fashion. Everyone is a winner unless you are the player that makes the tower tumble.
