Japanese Mahjong
Description (

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.}

引きが偏り過ぎで面白く無い。 良い時は良過ぎ、悪い時は当たり牌を最初に引いてくる傾向にあるようだ。 アルゴリズムに問題があるようで面白く無い。

I really like the app. It would be nice to have the option to see the Japanese yaku names when someone wins.

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.

Приложение понравилось, но для игры нужны хотя бы минимальные знания об игре. Пока так и не понял, что значат стрелочки на сыгранных камнях...

捨てる牌を選ぶ時、勝手にスワイプ(ホームボタンのような形)になり、戻ると捨てたくない牌を捨ててしまう。 それさえなければ良いのに。 ホームボタンのないiPhoneには不向きなアプリです。

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!

・王牌が5列なのはどうなの? ・何となく動作が重い→(追記)アップデートで解消 ・河が6×3はGood ・聴牌時、牌の選択を変更すると、リーチボタンが消えて、一旦中断しないとリーチできなくなる (追記) ・リー即でもリーチ成立扱いされ、リーチ棒が回収される(v4.3で解消)

I use this game to get better at Riichi Mahjong. It has helped a lot since you can get so many games in so quickly and the CPU makes you aware of every move possibility. The downside is that the game is way too hard and has no difficulty setting (confirmed with dev.) If you can still have fun losing nearly every game then dig in.

まるでcpu同士で通しでもしているかの様にcpuの立直一発が多い。cpuの立直に対して3〜4回に1回は一発で上がっていく。 それ以外は概ね満足。
