Tatami Duel

Hajime! Take a grip, pull and push to break your opponent's balance (kuzushi), then throw. If the throw doesn't finish it, the fight goes to the ground, where you can pin for osaekomi. A referee calls every throw, score and penalty in Japanese with the IJF hand signals.

Never done judo? Starter mode keeps it to step, grip and throw. The game picks the throw that fits your opponent's balance, and a gold hint tells you when to grip and when to throw.

Expert mode lets you choose the throw yourself: seoi-nage when you pull, uchi-mata standing still, o-soto-gari when you push. It adds the foot sweep, counters, belts from white to red-and-white, golden score, shido penalties and a tongue-in-cheek national superpower for each judoka.

Score waza-ari with a good throw or a 10-second hold, and ippon with a clean throw, a 20-second hold or two waza-ari. Three shido and you're out.

Play against the bot on Easy, Medium or Hard, or fight a friend on the same device. Contests last 2, 3 or 4 minutes.
