It's the classic block-stacking, stack-crashing game of Jenga. How will you stack up against the law of gravity? Stack the wooden blocks in a sturdy tower, then take turns pulling out blocks one by one until the whole stack crashes down. Is your hand steady enough to pull out the last block before the tower collapses? Pull out a bock without crashing the stack to win at Jenga. 54 hardwood Jenga blocks. Win by being the last player to remove a block without causing the stack to crash.
