Prefecture Survival

Prefecture Survival is a watch-and-cheer battle royale: the shapes of all 47 Japanese prefectures bounce around inside a ring, and any prefecture that slips through the rotating gap is out. The last one standing wins. HOW IT WORKS 1. Tap Start and all 47 prefectures start bouncing after a 3-2-1 countdown 2. Part of the white ring is open. The gap rotates and slowly widens 3. Any prefecture that flies out is eliminated, and the elimination order is listed live at the top 4. The last prefecture standing wins.
