Is there an American mahjong practice app for Android?
Yes. Mahj Trainer: Mahjong Practice is an American mahjong practice app for Android, available on Google Play. It teaches the tiles, the card's sections, the Charleston and keep-or-throw calls in five-minute drills, with the reason shown after every answer.
It needs no opponents and no account, and four practice rooms are free.
What can you practice on Android?
Four free rooms, each a short drill on one skill:
- The Tile Room: flashcards on every tile family, then a quiz on the rules new players mix up, such as which dragon goes with which suit and what jokers can do.
- The Card Room: flashcards on the card's sections, then racks of 13 tiles where you name the section they are chasing.
- The Charleston Room: practice deals where you pick three tiles to pass and compare with the coach. More on the Charleston practice page.
- The Table Room: keep-or-throw calls and table rules: when to hold a flower, when to swap for an exposed joker, which discards are safe.
Also free on Android:
- Play a Hand, once a day: thirteen tiles off a real wall. You commit to a section, then draw and discard while the coach grades every throw and shows the arithmetic.
- How to Play: a short primer for new players, one tap from the home screen.
- A searchable reference and glossary.
Streaks and per-room progress show which skill needs work, and a quick mixed session brings back the questions you missed first.
