### 1/5 — 麻雀じゃ無い!

*2025-08-24, version 32.4*

麻雀ゲームするなら!他のサイトの方が面白いですネ\(//∇//)\

### 4/5 — 良いんじゃないですか(^^)

*2025-07-22, version 32.1*

オンラインゲームとしては色々と楽しみ方があって中々、良いんじゃないですか(^^)

### 1/5 — イカサマ

*2025-03-15, version 31.5*

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。

### 5/5 — ネット麻雀だけど！

*2024-10-15, version 29.4*

本当に卓を囲んで麻雀をやっている緊張感に加えて凄く楽しく麻雀が出来てます。本格的な感じです。麻雀牌もやや丸みを帯びた感じで可愛らしく、見やすく表現されていて大変良いです。ツモ、ロンアガリのエフェクト、プロ対局、チャット対局、そして極め付けはボイス配信と、雀ナビ作りに携わったゲームクリエイターの方の感性がとても素晴らしいと実感しました！あと麻雀をよく理解しているんだなと同時に思いました。数ある麻雀ゲームの中でも群を抜いて素晴らしい作品だと思いました。これからも雀ナビを応援します！

### 5/5 — いつもありがとうございます。

*2024-10-03, version 29.4*

忙しい時でも対局まで案外スムーズに行えますし、それだけ会員様も多いのだと思います。これからもよろしくお願いいたします。

### 1/5 — 落ちる

*2024-09-23, version 29.2*

iPhone xrを使ってます。本体を18に更新したら、すぐに落ちて遊べません。iPadで遊ぼうのも引き継ぎコードも出せません。プレミアム会員でお金だけ引き落とさせるので、早急に改善してください。

### 1/5 — ん？

*2024-09-12, version 29.2*

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。

### 1/5 — イケてない

*2024-08-27, version 29.1*

キャラとかアイテムとか画風がめちゃくちゃダサい。。。
トップを取り続けないとチップが減って、続けるには課金が必要になる。
課金を前提とした設計。

### 5/5 — とにかく面白い！

*2024-08-16, version 29.0*

さすがマージャンゲームの真骨頂！
ver upも頑張ってくれていますが、ちょっと追いついていないところもありますが我慢できます。
予約の待機は以前の参加者が見える形の方が良かったなぁ〜

### 5/5 — ポンとチー

*2024-07-08, version 28.6*

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〜
