A spin-off of the popular Jenga dexterity game, Jenga BOOM's gameplay remains largely the same as its forebear, with one big twist: the tower of wooden blocks rests upon a plastic "bomb" platform. Before the game starts, players pull a string on the side to start the ticking timer. Each turn, a player must press the "play" button to restart the timer and then a "stop" button once he's finished his turn. When the timer runs out, the platform drops, leveling the tower, and the player whose turn it is loses.
