MJWin!
HK Mahjong Fan Calculator
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
MJWin! is the App Store name of MahjongWin!, also known as 雀勝！ in Chinese. It is a scorekeeping, fan calculation, match-recording, and settlement utility built for offline Hong Kong mahjong games.
Every mahjong table has its own habits and house rules. MahjongWin! is not here to change how you play. It is here to make scoring, fan calculation, recordkeeping, and final settlement clearer, faster, and less error-prone.
Create a room, let players join, record each round result, and MahjongWin! will help update the scores and keep a clear match history.
The key feature is the Hong Kong mahjong fan calculation system. When a player wins, simply enter the winning hand pattern and relevant conditions, such as discard win, self-draw, concealed hand, honor tiles, full flush, all pongs, and other scoring patterns. MahjongWin! helps calculate the fan count automatically based on the selected room settings.
Main features:
・Hong Kong mahjong fan calculation
Enter the winning hand pattern and related conditions. MahjongWin! helps calculate the fan count automatically, reducing manual mistakes and table disputes.
・Create and join rooms

・Record each round

・Score updates and settlement
Scores are updated after each recorded round. At the end of the match, view a final ledger showing each player’s result clearly.

・Guest mode
Players can join quickly as guests, making it easy to start a table during offline gatherings.

・Hong Kong mahjong players
・Friends and family mahjong sessions

・Players who want clearer settlement and match history
