This is a Mahjong game of the Japanese style rule.
The Slider that exists under the screen is moved, and the tile is selected.
And, the Slider is done in the tap and the tile is discard.
Mahjong is the game to finish four Melds and one Pairs.

Example: [1, 2, 3][6, 6, 6][6, 7, 8][N, N, N][4, 4]

However, there is a hand not approved when Chi, Pon, and Open Kan.
Please note whether there is a hand when you do 1 and 9 in Chi and Pon.
In the rule of the japanese mahjong, one or more hands are necessary.
The hand can be made by paying 1,000 points and doing Reach.
However, when Chi, Pon, and Open Kan are done, Reach cannot be done.
If it is a closed hand, high point will be obtained.
About Lost Hand. A hand that is Waiting, but cannot be won off someone else's discard due to the fact that the owner of the hand already threw a winning tile in their own discard.
Lost Hand if one in all winning tiles are here even if discard doesn't do the tile which it wants to do. But, self-draw is possible even with Lost Hand.
The knack is that Ron is never done by the other party.
Ron is never done with the tile that does Discard.
Please reason the Hand from other party's Discard and win.

Great Japanese Mahjong game

Clear instructions, good scoring system. Easy to understand for beginners but challenging enough for experts

Good fun app for beginners

Its pretty hard to find a good mah jong app but if you're looking for fast paced ai mah jong, you've found just what you were looking for. The only problem is that you can't play horizontally(only vertical) making it hard to press tiles if you have sausage fingers. It also has the ability to change from English tiles to japanese as well as the hands in japanese. Definitely a good purchase for any mahjong player to have a little fun.

Fix the bug

So I love this app on iPad, and I have an iPhone 6s Plus, so I got the iPhone version too. I can't play a game on the iPhone version. It should allow screen rotation and not have the lame tap confirm play. The iPad app is near perfect, though I was I could play online or even via local or Bluetooth would be great. Please fix the app and allow me to enjoy Richii anytime anywhere I want 😊. Oh and if you have an open Kan and try to "self-draw" dumb name since it's just drawing a new tile. Anyways it won't let me draw a tile after an open Kan. Couldn't play a game.
