About this app
Hanafuda Koi-Koi Go-Stop brings the classic East Asian flower card game to your phone — known as Koi-Koi in Japan and Go-Stop in Korea, played with the same 48-card Hwatu deck. MATCH THE MONTHS Twelve months, four cards each. Match a card from your hand to a card on the field by its month to capture both — then draw from the deck and match again. Simple to learn, deep to master. SCORE REAL YAKU Chase authentic scoring combinations: Five Brights, Three Brights, Boar-Deer-Butterfly, Poetry Ribbons, Blue Ribbons, Moon Viewing, Flower Viewing, and more. Every yaku from the traditional rules is scored correctly. KOI-KOI OR SHOUBU Complete a yaku and you get to choose: call Koi-Koi to keep playing for a bigger score, or call Shoubu to bank your points and end the hand. Push too far and your opponent might catch up — that tension is the whole game. PLAY YOUR WAY - Three AI difficulty levels: Easy, Normal, Hard - Best-of-three matches with running scores - Clean, fast, no ads, no gambling, no real-money wagers — just the game - Works completely offline Whether you grew up calling it Koi-Koi, Go-Stop, or Hwatu, this is the same beautiful game your family plays at New Year's — now on your phone, anytime.
