What's New in Mahj Trainer

1.4.2

October 29, 2026

A drill you leave now waits for you, on the same question. On the unfolded iPhone Duo, Home and your drill sit side by side. Every answer fits on smaller iPhones, and the largest text sizes read cleanly. The Mahj Minute rolls over at midnight and on the first of the month without losing a point. Two answers were corrected: the junk pass in the Charleston and the dead quint with jokers. Reduce Motion is respected everywhere.

Great app

I’ve been reading about mah Jong but this allows you to actually test what you know or learn new stuff. Very helpful!

Incorrect information

Incorrect information several times. You can not call a joker ever.

Response from developer

Thank you for the feedback. A discarded joker can never be called, for mah jongg or anything else. One question in Joker School was worded ambiguously, so I've rewritten it to make the rule clear. The update is in version 1.3.1, available now. If anything else looks off, Settings > Send Feedback comes straight to me. Jack

Great!

Nice to practice without the card anywhere anytime
