You take turns with other players removing rectangular wooden blocks from a block tower. Each time you take one out, you put it on top. The object is to not knock the tower over while removing pieces. In difference of some other Mechanism: Tower Stacking, you must space out the blocks on Tumbling Tower in order for it to make a nicely shaped tower.
