Sumo

Push your opponent out of the ring. There are three positions and no mercy.

A tiny two-player duel: the sumo ring has just three spots — left, centre, right — and you're playing cards to shove your opponent out of it. Minimal rules, maximum bluffing.

Small enough for a pocket, sharp enough for a rematch. And another. And another.

Perfect for: Two-player households, travel, and quiet people with a competitive streak
