For those who are interested in Mahjong and want to improve their game skill: R Mahjong - Japanese mahjong for 4 people with strong mahjong AI, training mode with AI tips, advanced system for collecting and displaying statistics. You can play with friends on a local network via Wi-Fi (no internet required). Missing players are automatically replaced by bots. The application is completely free. http://riichimahjong.net/
This is a mobile app, you can't play on your browser which seems like a huge oversight. Not sure if you are the dev but you should add a theme that mimics the mobile game seen in Pon no Michi (>>/an/37785). And the most important feature should be the riichi button that goes "Pin pon... riichi!"
