About the app
Mahjong Helper is a calm table-side companion for Hong Kong-style / Cantonese Mahjong. Learn the tiles, Chow, Pung, Kong, calling and winning; enter a physical hand by tapping tile pictures; validate its structure; and see why it scores under Hong Kong Old Style — Standard Beginner Preset. English explanations include Traditional Chinese Mahjong terms. The app supports concealed and declared melds, Flowers and Seasons, configurable minimum faan and caps, special hands, Quick Help, searchable lessons, and friendly practice questions. It works offline after installation with no account, ads, analytics, camera, AI or cloud service. Rules and faan values vary by family and club, so agree on your table's house rules before play.
