Kai-awase is the Heian court game this whole genre descends from. Clam shells were split and both halves painted with the same scene; only the true pair fits together. The motifs here are the ones those shells actually carried.
At the start of each round, all cards are revealed for a few seconds. After they flip face-down, tap two cards at a time. Matching pairs stay face-up. Non-matching pairs flip back after a short delay.
Clear the board by finding all matching pairs with the fewest flips possible.
