It fully supports both four-player (4-player mahjong) and three-player (3-player mahjong/Sanma) games.

It's useful in a variety of situations, from managing personal scores to sharing results with setmates or club members.

[MA-Stats Main Features]

■ Fully Supported for Four- and Three-Player Games
In addition to standard four-player mahjong, it also supports score calculation and recording for three-player mahjong (Sanma). Detailed rule settings for each game mode (Uma/Oka, Nishiiri, Yakitori, etc.) are also flexibly customizable.

■ Overwhelming Analysis Functions
More than just recording rankings and raw scores, MA-Stats visualizes your mahjong skills from multiple angles.

・Rank distribution, consecutive win rate, and last-place avoidance rate
・Win rate, conceded rate, riichi rate, and furo rate
・Average ranking and overall balance
You can view these data not only numerically but also in easy-to-read graphs. Identify your playing patterns and weaknesses and use them to improve your mahjong skills.

■ Instant sharing and cloud synchronization with QR codes
Game data is securely stored in the cloud. Data transfer is easy even when changing devices.

Additionally, simply scan a QR code to join a game. You can instantly start sharing scores with other players without the need for a complicated ID entry.

■ Group (Club Room) Feature
You can create "groups" for your set or mahjong club.
Manage and tally the performance of all group members, and display group rankings and compatibility data. Enjoy even more exciting mahjong fun with friends.

■ Tournament (Event) Feature
Create and manage "events" such as one-day tournaments and league matches.
Automatically generate rankings based on specific periods or games, dramatically reducing the effort required for tournament management.

■ Intuitive Score Entry
The intuitive UI allows you to quickly enter complex score transfers unique to mahjong, such as winning (ron/tsumo), draws, and transfers of points. Prevent calculation errors and focus comfortably on your game.

■ Extensive Theme Customization
In addition to dark mode support, you can change the app's color theme to suit your preferences. Enjoy a personalized, easy-to-read screen.
