All-Star 4-nin Uchi is a version of Super Real Mahjong PV that focuses on four-player mahjong game (as in professional competitions, with North, East, West, and South sides) rather than one-on-one strip mahjong. Instead of only three female opponents the game has nine, including characters from previous entries in the series. Players can choose between a tournament and a team mode, in which three teams made of three girls each compete against each other. Also included is an extensive mini-game mode: each of the nine girls offers her own mini-game. These games are fairly simple, usually containing only one screen, and range from a jigsaw puzzle to cake-baking and balancing a motorcycle on a log.
