Hosted by Janelle James, four teams of contestants compete in an epic battle against gravity and physics as they attempt to remove items from towering themed stacks. In round one, a dynamic father-and-daughter duo fights to beat a pair of childhood friends after they confront the birthday stack. In round two, it’s double the trouble when twin brothers take on a couple of best friends and the sports stack. The winners from each round face off against the pirate stack to earn a shot at The Mega Stack and a chance to win the grand prize of $250,000.
