Koi-Koi: Hanafuda Card Game

Classic Japanese hanafuda, with a real 1902 woodblock deck. Play Koi-Koi, Hana-awase and Hachi-Hachi free, with no ads and no tracking. In Settings → Look, switch to a Meiji-era Kyoto woodblock card deck and genuine public-domain prints by Hokusai and Hiroshige, or keep the animated deck and illustrated ukiyo-e-style stages. Free to start, one-time unlocks only: no subscriptions, no timers, no energy. THREE TRADITIONAL GAMES, NOT JUST KOI-KOI • Koi-Koi (こいこい): the classic two-player duel. Match months, build yaku, then bank your points (Shōbu) or call "Koi-Koi!" and press your luck. • Hana-awase (花合わせ): three-player parlor hanafuda where every card has a point value and yaku settle against both opponents at once. • Hachi-Hachi (八八): the traditional three-player game, with field multipliers (平場 / 大場 ×2 / 絶場 ×4), opening-hand Teyaku and Dekiyaku finishes. AUTHENTIC PRINTS (Settings → Look) • A 1902 Kyoto woodblock hanafuda deck (明治木版), from the collection of the Bibliothèque nationale de France. • Museum Print stages: original public-domain Hokusai and Hiroshige prints as the table behind your cards. • Switch back to the animated deck and illustrated dioramas whenever you like. A STRONGER OPPONENT • Four CPU levels from Easy to Expert. Expert looks ahead over the cards it can't see instead of guessing. • Seven named rivals across the Hokusai Battles journey, each with their own stage. DAILY CHALLENGE • Everyone gets the same three seeded deals each day against a rotating rival. • Post your score in one tap to the daily leaderboard and share your round-by-round result card. LEARN AT YOUR OWN PACE • Bushido Bob's tutorial runs once on your first match, and you can skip it. • Optional month-matching colour borders, yaku progress hints and a full yaku reference. • Plays fully offline, and the download is about 80% smaller than before. ONE-TIME UNLOCKS (NO SUBSCRIPTIONS, NO ADS) • Free: Stage 1 at Red Fuji against Nitō, the Ronin in Koi-Koi, Hana-awase and Hachi-Hachi; the Daily Challenge and leaderboard; the 1902 woodblock deck and Museum Print stages; all four CPU levels. • Hokusai Battles ($2.99): the full seven-rival Journey, from Nitō at Red Fuji through Kōchō, Onizō, Dakki, Michikaze and Yukimori to Chie, the Tideward at Suruga Bay, across 7 living ukiyo-e dioramas. • Kissa Chaos ($1.99): six themed Japanese cafés with six voiced hosts, from Momo at Sleepy Cat Cafe to Ruri at Shibuya Maid Cafe. • Last Train ($1.99): one after-work Tokyo night across 6 stages, from The Corporate Dinner (7:05 PM) to Karaoke Transcendence (1:17 AM), plus the Monday Morning epilogue. • Talk Show + Cross Mode ($0.99): live commentator reactions during play, studio arguments between rounds, and Cross Mode cast mixing across every world you own. • Complete Collection ($3.99): Hokusai Battles, Kissa Chaos, Last Train and Talk Show + Cross Mode in one bundle.
