User reviews

Excellent Learning App for Mahjongg

This app is perfect! The information is presented in clear language, manageable amounts of new info, and scaffolded levels of difficulty. The interactive question/answer format lets the user know how they are progressing, and the ‘quiz’ at the end of each lesson reinforces the information.
I used this for two weeks before taking lessons and I was prepared and confident when we began playing.
It is also an excellent value!

Great for beginners

This app takes you from the very beginning, identifying tiles, through actual games that are paced from slow to fast. The lessons are well-organized, and you can go back and forth when you need some extra practice in some areas. Couldn’t be better, and such a good price!

Great Teacher!

So far so good! I’m very excited to start learning American Mahjong 🀄️ and it’s great to have a teacher right in the palm of your hand! Customer service and attention is excellent as well! Good luck to all my fellow Mahj-ers that are starting to learn like me too!

Bait and switch

I understand in-app purchases, but this was a total bait and switch. There are 18 lessons, and after three they force you to pay to continue. No other options. Would never recommend.

Soooo helpful!!

I’ve played only a couple of times and this app is incredibly helpful in reviewing basics so I don’t embarrass myself. It’s easy and very well made.
