How to play
- A two-player Japanese hanafuda game. The 48 cards form 12 months (suits) of 4 cards each, graded as brights, animals, ribbons and chaff. The number in the corner is the month.
- Each player gets 8 cards and 8 go face up on the field. On your turn play a card: if the field has a card of the same month you capture both (choose one if there are two; take all if there are three), otherwise it stays on the field.
- Then flip the top card of the draw pile and match it the same way, or leave it on the field.
- Captured cards score when they form a yaku. After making one you can call Koi-Koi to keep going for more, or Shōbu to end the month — but if your opponent stops first after your Koi-Koi, their score is doubled.
- A match lasts 6 months by default (12 optional); the higher total wins. Online, each move has a 20-second limit; on timeout a card is played for you and auto-play takes over.
