### 5/5 — Great game broken by iOS8

*2023-01-06, version 1.1.3*

Broken under iPadOS and iOS 16.2. The last tile or the Game menu crashes the app. 

 An older version enables play under iOS8. Thank you very much. Great game.

### 5/5 — Love it!

*2021-07-16, version 1.1.3*

Another commenter described Zen Twins as “digital heroin.” I agree.

### 3/5 — Rivers Mahjong

*2020-12-06, version 1.1.3*

I used to have a choice of tiles, cereal boxes, spheres, etc. with a previous iOS update. What happened to my purchases?

### 5/5 — Very good game, I wish they would make one small addition

*2017-09-17, version 1.1.3*

This is a very good version of shisen-sho. A good game to play when waiting or when you have down time. I would enjoy the game more if there was a way to turn off timing.  That change would make this game good for stress relief as one could just play at a leisurely pace (I've enjoyed shisen-sho on Linux for several years.  Except for the inability to turn off scoring this version is much better than the Linux version).

### 5/5 — Good app

*2016-09-29, version 1.1.3*

I enjoy this version of mahjong more than the regular one. Only improvements I would like would be a two layer game and hints for when I get really stuck!

### 5/5 — Beautiful & Fun

### 5/5 — My favorite app works again!!!

*2015-05-03, version 1.1.3*

Beware! This app is Digital Heroin! Once you start...you are hooked. Thanks for getting it working again. I missed it so much!
