5月からプレミアムの有料課金サービスの解約についてアプリで不具合のようで、手続きが進まず相談フォームで何度も相談してますが、連絡もなく4ヶ月が経ちます。消費者相談してます。カスタマー対応が悪いですし、注意した方が良いと思います。

度重なる悪改とイカサマアルゴリズムで課金しないと楽しめないゲーム。 純粋に麻雀を楽しみたい方にはとてもおすすめできません。 低評価を付けたり運営に物申すと、分かりやすく三人麻雀では考えられない様な最悪な配牌と最悪なツモ(一九字牌や切った牌の近辺ばかりのツモなど)で笑えるぐらいに負けさせられます。 試してみるとイカサマアルゴリズムを経験できるので興味ある方は試してみて下さい。 また低評価と悪いレビューは意図的に削除されます。 こちらも何回目かの投稿です。

無課金なのでこんなものなんでしょう 2000位は直ぐに負けます あり得ない程に配牌操作されていますので、課金前提だと悪くはないかも 無課金には厳しいアプリ

違うアプリで麻雀やってたときは、課金した人(アイテム持ち)ばかり上がる感じがして面白くなかったけど、コレはリアルで打ってるみたいで面白いです。

やはりイカサマですね。只今動画配信で検証中テンパイの速さ手の大きさ全てにおインチキの可能性大です。プレイしない事をお勧めします。

配牌裏返しで バグ? 考えてる間に勝手にほられたのが赤ウーピン なんなんですか?捨て牌時間余裕あるはずなのに強制されたり 完全に課金者の当てごまにされてますね。 ただだからそれでもいいけど もう少し配慮欲しい  当てごまの無課金者が 離れますよ。

今一つUIがたどたどしくてスムーズでは無く、何よりマッチングに時間が掛かる。 上段以降は特に少なく、仕方なく初心者卓で上段者もプレイしているため、そもそも麻雀初心者にはハードルが高いと思われ、それが更に過疎化に繋がっている気がする。 上段以降の長く遊んでいるプレイヤーへの特典をもっと増やして、より自分の段位や実力に見合った卓でプレイするインセンティブが必要。 今後仮想通貨(JNトークン)を発行するらしいが、現状では価値や先行きに期待は持てない。 古参のアプリなのでUIが古くさく、他のアプリと同程度のスムーズな麻雀体験が出来るように改良しないと発展は望めず、更に過疎化が進みそうだ。 あとキャラとかアイテムとか画風がめちゃくちゃダサい。。。

ポンとチーは、同時に発声した時のみポンの権利が有ります、先にチーしても後からポンに負けます、 チーが100%負けます。ゲームでは仕方ないですね〜

よく分からないままやってますが、今のところ課金もなく、楽しく遊ぶことができています✋ 名前の変え方が分からないくらいで、あとはなんの問題もないです🙂
