About the app
New to Hong Kong Mahjong? Sitting at a table with experienced players? Mahjong Helper is a calm, offline companion for learning the tiles, scoring a hand, and tracking a live game with physical tiles.
Built for real tables, it combines a Hong Kong Mahjong score tracker, hand checker, rules guide, and beginner lessons in one focused app.
Track a live game
- Add four player names and starting seats.
- Follow round wind, seat winds, dealer, and cumulative scores.
- Record discard wins, self-draws, or draws in a quick popup.
- Use Standard payouts or save named tables for your family or club.
- Review every hand, undo mistakes, and resume the game anytime.
Learn, check, and score
Identify tiles, learn calls, enter a physical hand, validate its structure, and see why each scoring element earns faan under a visible Hong Kong Old Style preset.
Made for the whole table
Large controls, screen-reader tile descriptions, dark mode, Android font scaling, English explanations, and Traditional Chinese terminology are included. The app works offline with no account, ads, analytics, camera, or cloud service.
Mahjong rules, faan values, and payouts vary between families, clubs, and regions. Agree on the table rules before play. Mahjong Helper keeps the selected rules and payout table visible and configurable.
Mahjong Helper is for Hong Kong-style / Cantonese Mahjong. It supports a physical game; it does not simulate opponents or replace agreement among the players at the table.
