修正おねがいします!

いつも使わせてもらってます!!

①点数計算練習で一発の表示がないのに解答で一発が適用されてしまっているときがあります。

②点数計算機として使った時、

1s1s1m1m2m2m2m3m3m
鳴き:9p9p9p
1mロン和了

とすると、高点法により
正)対々和 2飜40符 2600点
となるところが、
誤)純全帯么九 2飜30符 2000点
となってしまいます。


よろしくお願いします!!

Response from developer

ご指摘ありがとうございます。こちら4.16.0として修正して提出いたしました。 点数計算については、 食い下がり判定前の役リストで、高い方を採用するバグになってしまっておりました🙇

やりずらくなった

前は隙間時間に軽くできたのに今は課金制
しかも問題の出し方も変わっていてやりずらくなった。回答も下二桁は00着いてたのに無くなったしもう使わない。

追記
バグなのか知らんが回答を入力すると全く違う問題に切り替わって不正解にされる。もう消すわ。久々に開いたけどこれはやばい

うわなんか課金制になった

せめて最初の買い切りにしてくれよ、流石に月440円出すなら要らん

なんとかしてくれ

有効牌の練習でツモってることが割とある。それ以外はとても有用です

牌を押すと反応が悪い!

すぐに解りたいのに完成図を作るのに5分かかる
