Paper Sumo (2015)

From the publisher: Ready, set, sumo! Japan's centuries-old national sport is the main attraction in this paper-based smackdown where creativity and competition collide. The result? Laughs guaranteed! There is an impressive assortment of 39 characters—from traditional sumo wrestlers to animals to monsters and other eye-catching creatures from Japanese lore. Additional characters can be created by drawing on customizable shapes. Then battle it out against an opponent's character on the sumo doyho ring. With each player tapping on his or her side of the doyho, the stakes are high until one of the characters falls and the other wins!
