Hanafuda. Your build.
Hyakki Hanafuda combines the Japanese card game Koi-Koi with roguelike deckbuilding. Face yokai opponents through three chapters and twelve months, shaping your cards and blessings along the way.
BANK IT. OR RISK IT.
Make a scoring hand, then choose: bank your points or call Koi-Koi to raise your multiplier and keep playing. Read the table before your opponent wins the round.
FIND YOUR COMBINATION
Mix 41 blessings with card upgrades. Build around the hands you want to make, choose what to buy, and decide which blessings to keep or replace.
CHOOSE YOUR PATH
Travel between matches, shops and shrines. Clear all twelve months to unlock Endless Night. New starting decks and blessings offer different ways to approach your next run.
LEARN BY PLAYING
Play a full guided round against Nekomata to learn matching cards, making hands and calling Koi-Koi. Check scoring hands during play and turn matching-card hints on or off.
