The best in the west

I found Richii Mahjong from Akagi. This app is how I learned the game while also getting to understand the hype of Akagi! I have had this app for over two years now and the fact the dev is still updating ever now then is great aslo. Online play is great if you get some friends to play; otherwise not really anyone there.
TLDR: Great for learning the game and offline play. Online; you better have friends or people to play other wise no one as of yet.

Great for beginners

I spent a good few years trying to learn mahjong online, and this is the best so far.
I used to have another mahjong game i used to play and pay for (single time) on iOS until they removed it from store. I got a new phone so needed a new app on mahjong.

This game actually teaches you how to play, i already had a good grasp of the rules after trial and error (such as when other game wont let you use a move that is not allow) but still was not clear on fruiten, or chombo moves. The game will penalize you if you try doing it. Other games won’t! Learn from mistakes! Best way!!

I guess if i had to nitpick, it will be game sound, but I enjoy it!

I’m so glad I found this game online as I really miss my monthly mahjong with friends! When playing with a friend in private however the game keeps kicking me out or quitting on me which is beyond frustrating! I hope that gets fixed and also I hope it will be possible to play with four of us privately instead of the AI . Also we use to play all four winds through ! I’d gladly pay for this ap if those problems are resolved. Fun game regardless, thank you!
