## What is Paper Sumo?

Tap the cardboard ring and the paper wrestler trembles forward.
Paper sumo (kamizumo) is a Japanese children's game: two folded-paper wrestlers on a box, moved only by drumming on the lid. This is that game, with real paper and cardboard textures and a physics simulation.

■ How to play
• Tap the screen rapidly: the box shakes and your wrestler inches forward
• Push the opponent out of the ring, or topple them, to win
• Tap too hard and your own wrestler falls. Rhythm is everything

■ Three ways to play
• vs CPU: a quick bout on your own
• 2 Players: put one device between you and drum on your own end
• Online: in the same room, connect directly over Wi-Fi/Bluetooth (no sign-in); far away, play through Game Center

■ Design your wrestler
Choose a ring name, face, skin, hair, mawashi colour and pattern, and paint anything you like with the brush.
The caller announces your wrestler and the referee's "Hakkeyoi, nokotta!" starts the bout.

■ Details
• Paper folds, corrugated cardboard, a wood-grain table: the textures of the real toy
• The paper wears out with use and can be replaced with a fresh sheet
• The decisive moment replays in slow motion and the winning move is announced
• Tsugaru shamisen music, wooden clappers and a cheering crowd

One purchase, no ads, no in-app purchases.

Music: Tsugaru Janbara Bushi / Momijiba Music
