The app offers various Hanafuda card games, including Koikoi, Hana Awase, and the highly strategic Hachi Hachi. Players can compete with AI at three difficulty levels or use a "cheat mode" for easier wins.
The app allows players to repeatedly press a button to achieve the rare "Tenhou" hand in Mahjong. It features a "Kakuren" mode where specific tiles are fixed to increase the chance of achieving Tenhou.
The app is an immersive, scroll-command RPG where actions synchronize with music. Players guide the protagonist, Oks, forward, with one turn passing per musical measure.
