Mahjong Just for Fun

New to American mahjong? Mahjong Just for Fun gets you from a dealt rack to a winning hand, at a real table, with real people, without holding up the game.

Pick the card you are playing, enter your tiles or photograph your rack, and the app shows you the closest hands on the card, how many tiles away each one is, exactly where to find it on the printed card, and what to pass or discard. The Charleston stops being a mystery: every pass comes with a recommendation and the reason behind it.

WHAT IS IN THE APP
- Four original Just for Fun cards (2026 through 2029) built in, every hand shown in card colors
- Any other card, added by photographing it. The hands are read in, shown for your review and kept on your phone
- Tile scanning from a photo of your rack, always shown for review and editable before it counts
- Charleston coaching with ranked passes at every step, plus a learning mode where you choose first and then compare
- Discard advice, call detection and mahjong detection as the hand plays out

WHO IT IS FOR
Beginners who want to play with experienced friends and family this week, not next year. Experienced players who want a second opinion on a tricky rack. Anyone who has ever stared at a card and wondered where to start.

Mahjong Just for Fun is free, with an occasional ad after the Charleston. It is a learning companion for games played at a real table, not a game against the computer, and it is not affiliated with or endorsed by any mahjong league. Scanning sends only the photo you take to our server for reading; see the privacy policy for details.
