### 4/5 — Very nice

*2025-08-08, version 1.3.0*

The game is really nice and instructive. The Menu is helping a lot, nice graphic, nice options to be chosen. Only issue, sometimes the Dora calculation seems wrong. Overall very nice and I am very happy to have found this app.

### 4/5 — a

*2025-07-21, version 1.2.0*

Fantastic client for riichi mahjong. I wish the camera zoom had an option to hold the zoom in place with a reset button.

### 4/5 — Presque parfait

*2025-07-18, version 1.2.0*

Les explications des Yaku en français seraient l’apothéose !

### 5/5 — Best Mahjong Game

*2025-07-09, version 1.2.0*

Normally I’m not inclined to write reviews for apps but I had to say how great this game is.  The developer obviously put a lot of work into making this game as user/beginner accessible and it really helps for learning this specific Mahjong ruleset.  Favorite part is the ability to flip the table and everything rag dolls.  Great touch!

### 5/5 — PERFECT!

*2025-05-20, version 1.2.0*

A perfect design… so much fun playing this! The AR is awesome.

### 5/5 — Great Mahjong app

*2024-07-04, version 1.2.0*

This is a fantastic Riichi Mahjong app. Great tutorials and game play. Really well designed u/i and very stable. 5/5

### 4/5 — Good game, but I had some problem on M1 MacBook

*2024-06-15, version 1.1.0*

Positive impression about gameplay, sounds and UI.
On an M1 Macbook Air (Monterey) I had a problem with high temperatures in the CPU area. The consequence of this was the iBoot Panic error. I believe the reason is the lack of optimization of the application for systems based on Apple M1.

### 5/5 — Pure and amazing minimalist Riichi Mahjong.

*2024-05-15, version 1.1.0*

This game has everything you need to practice for fun or even to training your speed hand and yaku memorization. Difficult is well balanced to meet all players level. Also, you can create rooms for online games with your friends. 

The best part for me is that you can find all WMC rules and other Riichi variations, chombo allowed, etc. 

I’d would suggest only one little thing: put an “one page” illustrated yaku patterns for a fast consultation during game, like a button on the screen (instead of navigating through 2 or 3 menus plus yakus pages and tabs).

So, that’s it. Amazing app. Worth the time spent on this.

### 5/5 — Amazing, Honest App

*2024-05-01, version 1.1.0*

The developer is clearly a lover of riichi Mahjong, as this app is clearly a high quality Labour of love.

Excellent Rulesets and sheets, always accessible at any point in the game or in tutorials, makes it very easy to learn and apply rules.

Excellent and thorough tutorials.

Not a single ad.

Simple and clean interface. It might be a little basic but it’s no frills, everything and every available action is made clear.

Some graphical style. Calling certain game actions is still satisfying, with some nice effects when you get a Ron, or call a chi.

Runs smoothly, and no bugs.

Seamless, easy multiplayer. Creating a match is as simple as creating a room with a name and having others join it by putting in the name of that room. The net code runs smoothly and I never have noticed any bugs.

All this makes the app perfect for learning mahjong as well as just playing it casually with others. As it’s free and easy to set up for multiplayer you can easily convince others to download it for.

### 2/5 — Faulty

*2024-03-29, version 1.1.0*

I have downloaded this game multiple times because it has glitches. I had high games between 8 and 9 million points. But since then the game times out right around 4 million points. The keys stop working and a screen pops up that says ‘couldn’t load the saved game’ and ‘Oh no! The save file did not contain a valid mahjong game.’ ‘Try starting a new game instead.’
I don’t want to keep starting over! Kinda lousy.
