About
Read the sky each month and match flower cards with the flower spirits.
Weatherkeeper's Hanafuda is a game of Koi-Koi, the classic Japanese flower card game, where the weather changes what your hands are worth. At the start of each month, one of nine kinds of weather is chosen, and whoever wins that month gets a weather bonus. In sunny months, avoid the Rain Man; in rainy months, go after it. Snow rewards calling Koi-Koi again and again, while hail rewards stopping early. On top of classic Koi-Koi, you read the sky to decide which cards to chase and when to stop.
■ Nine kinds of weather
Sunny, Rain, Sunshower, Cloudy, Blossom Haze, Snow, Hail, Fog and Calm. The scenery on the table changes with the weather, with rain and snow falling.
- Tap the weather seal to check that month's bonus at any time
- If the same weather continues, the round winner gets an extra bonus
- When you make a hand, see how many points you would get by stopping now, weather bonus included, before choosing Stop or Koi-Koi
- Classic Koi-Koi without weather is available too
■ Three flower spirits
Your opponents are the flower spirits who live around a mountain shrine: Hydrangea, Spider Lily and Wisteria.
- Careful Hydrangea who loves the rainy months, bold Spider Lily who goes for it when it counts, and Wisteria who is good at collecting ribbons. Each has her own playing style and voice
- On Normal and Strong, the flower spirits also read the weather
- Three opponent strengths. Matches can be 1, 3, 6 or 12 rounds
