Free to try: learn hanafuda Koi-Koi with the tutorial and play 3 matches free. One purchase unlocks the full game. No ads, ever.
Koi-Koi is the best-loved game played with hanafuda, Japan's traditional flower cards. Match cards by month, capture brights, animals, ribbons and plain cards, and build scoring combinations called yaku. When you make one, decide: take the points (Shobu) or push your luck and call Koi-Koi for more.
WHY YOU'LL LIKE IT
- Free to try: the tutorial, rules and your first 3 matches are free. One purchase unlocks everything for good. No ads, no timers, no coins, no subscription.
- A fair opponent. The shuffle uses your device's secure random generator and the computer never sees your hand or the deck.
- Three CPU strengths, from relaxed to sharp.
- Learn in minutes with an interactive tutorial, plus a full scoring reference for every yaku.
- Two players on one device with a hand cover so nobody peeks.
- Five venues, each with its own calm original music: Koto Garden, Festival, Night Table, Temple and Moon Viewing. Pick one or let it change every round.
- 48 hand-composed illustrated cards in a woodblock-inspired style.
- Plays fully offline. No account, no tracking, no data collected.
- Made for everyone: VoiceOver announcements for every move, large text support, Reduce Motion, and English and Japanese.
HOW A ROUND WORKS
Play a card from your hand to capture a matching month from the table, then flip the top card of the deck and match again. Collect combinations such as Five Brights, Boar-Deer-Butterfly, the red and blue poetry ribbons, and moon or cherry viewing. Scores of 7 or more are doubled.
Perfect for newcomers curious about hanafuda and for lifelong players who want a polished, ad-free game.
