How do you play Koi-Koi online multiplayer?

Press "Play now" for online matchmaking with players worldwide, or "Private room" to create a game and share the link or room code with a friend. Both work in your browser with no download.

Can I play Hanafuda online for free?

Yes. Hanafuda Legends is free to play in your browser or on Android — ranked seasons, Daily Challenge, vs computer, and private rooms. No signup or subscription required. An iOS app is coming soon.

Koi-Koi is a traditional Japanese card game played with Hanafuda (flower cards). Two players match cards by month, capture sets called yaku, and choose to bank points or risk calling "Koi-Koi" for higher scores.

Play a card from your hand to match one on the table (same month), or add it to the table. Then draw a card and match or add it. When you form a yaku, you can stop to keep your points or call "Koi-Koi" to continue for more.

How do I play with a friend?

Click "Private Room", create a room, and choose how many rounds. Share the room code or link with your friend. They join with the code — no account required.

Yaku are scoring combinations of captured cards, such as "Five Brights", "Moon Viewing", or "Poetry Ribbons". Each yaku has a point value; the game explains them as you play.

Story

What it is

Hanafuda Legends is a free online Koi-Koi game. Play in the browser or on the Android app; iOS is in review. Eleven languages, ranked seasons, and every deck earnable by playing — nothing behind a paywall.

Why I built it

我第一次见到花札是在两年前，当时我读到《80年代的游戏环游世界》。它在日本很受欢迎，我对任天堂的历史很着迷，任天堂是从花札制造商起家的。

在玩过许多在线版本后，我想创造理想的数字 Koi Koi 体验，所以我创建了 Hanafuda Legends。这个项目是一项爱的劳动。希望它能给你带来游戏的乐趣。

What's different

No signup required to play — ranked, private rooms, vs computer and the tutorial all work without an account.
24 artist decks in the gallery, each credited to the people who made them.
Nintendo-standard Koi-Koi rules with house-rule options (Teshi / Kuttsuki and koi-koi variants).
