Isaac Newton and Elphaba — arguably the two biggest names on the gravity scene in the last 338 years. That is until now. In this nerve-jangling, card dangling game you’ll need a steady hand and a whole lot of luck. Because if the cards tumble down on your turn, you lose! PRO EDITION = MAXIMUM MAYHEM: This upgraded version features sturdier cards, refined balance, and optimized chaos for players who take their drinking games very seriously.
