How many items can you stack and balance on the Zimmer Twins’ magic tray? Find out when you play Stack Master, the tricky little balancing game. Drag items onto the stack and tilt your iPhone to keep things balanced. It’s harder than it looks! Watch out for swirls and tap them before they drain your psychic energy. Gain psychic energy back by tapping stars. And watch for sneaky 13—he might surprise you enough to drop your stack!
