About Chifoumi

A five-way game of rock-paper-scissors played with Stone, Blade, Cloth, Thunder, and Water. Before the match you spend 200 attack across the five hands, then five turns settle 120 HP. Play people online, or the CPU with no connection at all.

The rules and the screens are laid out on the home page.

Common questions

How do I start an online match?: Sign in with your Apple ID or your Google account, then join the queue and you are matched with someone who picked the same rules. No email to type, no password to set.
Do I need an account?: Not to play the CPU. You are never asked to sign in, and the app sends nothing to the server. An account is only asked for when you choose online play, and it can be deleted from the settings screen.
Who can see my display name?: Your opponent, anyone watching, and the match records. Finished matches and match histories are open to everyone, so keep your real name and contact details out of it. You can change the name any time.Read the privacy policy
Do spectators see what I am holding?: No. Spectators are only sent turns that have already resolved. Unplayed hands and either player's allocation are never sent to them.
Can I play without a connection?: CPU matches, yes — they run entirely on your device. Online matches and spectating need a connection.
Where is my data stored?: Your language, the rules you picked, the deck you built, and the card art you picked are stored on your device. Once you sign in for online play, a user ID, the identifier of the account you signed in with, your display name, your card art, and your match records are also stored on the server. Play only the CPU and nothing is kept on the server at all.Read the privacy policy
Which devices are supported?: iPhone running iOS 18 or later.
