Chifoumi: Rock Paper Scissors

Five hands in a ring: each beats two, loses to two. Spend 200 attack before the match, then play each hand once across five turns. Every hand is revealed. Plays offline.

Stone, Blade, Cloth, Thunder, Water. Five hands in a ring, each beating exactly two and losing to exactly two. None of them is the strong one.

Chifoumi takes that five-way standoff and adds one thing: you spend your attack before you fight. The shape of the match is set before the first hand is played.

■ Spend first, then fight

Before the match begins you spend 200 attack points across the five hands — at least 10 on each, in steps of 10. A hand you loaded up hits hard when it lands; a thin one barely stings. Your opponent cannot see where you put it.

■ Every hand played is revealed

Each turn you choose one hand you have not used yet. Win the turn and you deal exactly what the hand you played was worth. If you both play the same hand, each of you takes half of the other's attack.

Win or lose, both hands and both values are then revealed. Where did they load up? What is still left? Turn by turn, their allocation narrows down.

■ Each hand is played once

You start on 120 HP and the match runs five turns. There are only five hands and each is spent once, so five turns uses up all of them. The big hand you saved still has to come out sometime. What you lead with and what you hold back is the whole reading contest.

The 200 attack you spend is more than the 120 HP you start with, so a match that lands can end before turn five.

■ Play the CPU, no connection needed

The CPU spends its points differently every match — sometimes spreading evenly, sometimes stacking one hand, sometimes holding the heavy one until last. It never tells you which, so you read it fresh each time.

Every result is worked out on your device. It plays through in airplane mode, underground, anywhere. No account, no sign-up.

■ Change the rules

Starting HP, number of turns, total attack points, the minimum per hand, time per turn, and what a draw does are all adjustable. You can let hands be replayed, or reveal both allocations upfront. With five hands and no replaying, turns cap at five.

■ Look up the five-way

The in-app reference shows what beats what, any time. Arrange the five in a pentagon and each one beats the next along and the one three along, clockwise — all ten outcomes fall out of that single shape. The rim and the star both visit all five hands.
