American Mah Jongg practice

Mahj Trainer

Learn the tiles, read the card, practice the Charleston, and make better table decisions in short, approachable sessions.

Four rooms. One less intimidating table.

Mahj Trainer is a practice companion for new American Mah Jongg players. Each room uses a different kind of drill, so you can learn the vocabulary, recognize patterns, and build judgment without needing a full game around you.

The Tile Room

Meet every tile family and quiz yourself on suits, winds, dragons, flowers, and jokers.

The Card Room

Read 13-tile racks and learn to recognize the sections they might be chasing.

The Charleston Room

Choose three tiles to pass, then compare your decision with a coach's reasoning.

The Table Room

Practice keep-or-throw judgment for flowers, exposures, joker swaps, and safe discards.

Mahj Trainer uses original teaching hands and is not affiliated with or endorsed by the National Mah Jongg League. The yearly NMJL card is copyrighted, so the app teaches category patterns without reproducing it.
