Hanafuda Koi-Koi: A Classic Japanese Card Game

Hanafuda Koi-Koi is a traditional Japanese card game. This guide explains the English rules.

Koi-Koi (こいこい), meaning "again and again" or "come on," is a popular two-player game using Hanafuda cards (Japanese playing cards).

The objective is to create specific card combinations, known as "yaku," faster than your opponent. Players accumulate cards in a point pile by matching cards in their hand or drawn from a central pile with cards already on the table. Upon completing a yaku, a player can choose to stop and score points, or continue ("koi-koi") to build additional yaku for a higher score. While individual card point values don't directly affect the final score, they aid in identifying valuable yaku combinations.
