Janshin Densetsu - Quest of Jongmaster — About this game

Janshin Densetsu sets its mahjong encounters inside a fantasy journey following Chi Fou’s training quest. The arcade version moves the character automatically between events, keeping the player’s direct decisions at the tile table rather than in free exploration. Its joystick selects tiles and available actions before confirmation. Mahjong contests provide the obstacles along the search for the legendary sacred player, accompanied by the original adult presentation.
