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.

Fix the bug

This a new review as the older version of this app was much better and less buggy, but once those bugs were fixed and this came out.... now I just played a game with over six West Wind tiles in the game! What!? Please fix and print back the old look. 🤷‍♂️

Update: the newest version is great! Thank you for such a good app!

Redesigned for the worse :(

It’s the same (excellent) game underneath it, but the new user interface is, minus some improvements such as highlighting opponents’ discards more, bad. Tile faces are smaller, muddier, and largely obscured by the overlaid number. Blue dots and bams are nearly the same color. 3D is busier than the previous clear, simple 2D graphics and adds little. Unity takes noticeably longer to start than the old engine. I get it makes multi-platform support a lot better, but what price build convenience?

Frankly, I’d pay to have the old version back.

My go to for Riichi

If I don’t have time to play real people this is a pretty good way to practice. Scoring could be explained a little better.
