Block-building with an attitude, this great game challenges any number of players to keep a stack of yellow, red, and blue narrow blocks from tumbling down--while removing pieces from its middle or bottom and then re-stacking on top. Sounds simple enough--just roll a die and follow directions: the objective is to keep the tower of blocks standing, even as parts are shifting. The tense construction-deconstruction cycle makes for a lot of laughs and anticipation. --Tom Keogh
