## What is Koi?

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.
