How Koi-koi is played here

The rules this table deals by. Everybody at the table sees the same lines before the first hand.

  • Forty-eight hanafuda cards, twelve months of four. Eight each, eight face up, the rest face down.
  • Play a card matching the month of one on the table and take both, or lay it down. Then turn the top of the pile and do the same.
  • Captured cards make scoring combinations: the brights, the boar, deer and butterfly, the ribbons of a colour, and the counts.
  • Complete one and choose: stop and score it, or call koi-koi and play on. Call it and your opponent's next yaku scores double.

How it works

  1. Open a table. It gets a short code of its own.
  2. Read the code out, or send the link. Anyone you send it to sits down as a guest, without an account.
  3. Deal once everyone is seated — or give each empty chair a bot and start now.
