Details
The full picture
Written from verified facts; labels mark how strong each statement's evidence is.
What the game is
Cheat Koi-Koi is a single-player roguelite released October 20, 2026 at $7.64.
You sit across from the cheats of a nighttime gambling den.
The goal is to work your way to the den's owner, Ririka, and beat her for the prize.
The tagline is symmetrical: they cheat, so do you.
How koi-koi works
Koi-koi is a Japanese card game played with hanafuda.
You match cards from the same month to collect scoring combinations called yaku.
You can take your points now, or call koi-koi and play on for a stronger hand.
If your opponent makes a yaku first, you get nothing from that round - so every extension is a real gamble.
The cheating layer
You can peek at a hidden card or swap a card in your hand.
You watch your opponent's hands and eyes, then choose when to make your move.
Get caught and you pay a fine and lose access to that trick for a while.
Your opponents cheat too, so reading the face across the table matters as much as reading the cards.
Structure and who it is for
You pick who to face next as you work through the den toward Ririka.
Each match is decided by total points over several rounds, with extra rounds to break ties.
You set your stakes, which frames how much risk a single round is worth.
It suits players who want a roguelite built on reading opponents rather than reflexes.
