About this app
American Mahjong can feel like a lot when you’re just getting started.
There are tiles to recognize, patterns to understand, groupings to remember, and table language that experienced players seem to know without even thinking. American Mahjong Trainer was built to make that learning curve feel calmer, clearer, and much more approachable.
This app helps new and returning players build confidence before they sit down at a real mahjong table.
Instead of dropping you straight into full gameplay, American Mahjong Trainer gives you a friendly place to learn the foundation: what the tiles mean, how the game is structured, how hands are built, and how to start recognizing the pieces that make American Mahjong easier to understand.
Learn at your own pace with simple lessons, visual explanations, and interactive study tools designed for real comprehension.

Five-star share of ratings

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

Method and limits
What a missing label means
Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Limits of this report
- A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
- Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
- Not assessed is a state. It is never a zero and never a pass.
- A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
