[News text by Triforce/ds-scene.net] MeRAMAN released a Hanafuda game where you play Koi-Koi style against the CPU. In Koi-Koi style the player throws a card on the same suit card to capture them. The winner is the one who makes the special combination of several cards which is called a “Yaku”. NDS Koi Koi has a wifi ranking table built into it.
