### 5/5 — これは凄い

*2024-04-17, version 1.1*

ルールが難解で理解しずらいが、理解してしまえば解ける問題であり、次々にやってしまう中毒性あるパズルです。

### 4/5 — 難しいけど楽しい

*2023-11-22, version 1.1*

コツをつかむまでは小さい盤面でも全然解けないが、わかってくると楽しい。どうしてもできない時は、確定してるとこまでセーブして、１つだけ仮にバツをつけてみる。矛盾が出ればそこは丸で確定‥とやっているうちに、段々コツがわかってきます。もう少しセーブ枠あると嬉しいので-1です。

### 5/5 — ちゃんとしてたよ

*2021-01-17, version 1.1*

このアプリが高評価のわりにレビューがマイナスな意見が多かったので自分もやってみました。
 確定するところから埋めていけばちゃんと正解できるゲームです
 白を黒で分割してはいけない、このルールがいい味出してます
全部解き終わって達成感よりももっとやりたいという感覚に襲われてるのでアプデなので新しい問題が増えること長い目で待ってます

### 2/5 — ちゃんと解けるルートあるんだろうか？

*2016-12-14, version 1.1*

ヒント機能が実装されたけど、マスを埋め終わった後に間違ってる所を1箇所だけ × してくれるだけという
むずすぎる

### 2/5 — パズルとしては・・・

*2016-12-11, version 1.0*

黒の個数を書いてくれると答えが単一になるかも
解答例が複数あるのはちょっとまずいかなぁ

### 3/5 — よくわからない...

*2016-12-08, version 1.0*

何度やっても正解にならないし、何が正解なのかも分からない...
せめてヒントはほしいかも

### 1/5 — ルールが曖昧

*2016-12-04, version 1.0*

うーん

### 1/5 — ルール通りなのに

*2016-12-02, version 1.0*

ルール通りなのに正解にならない
多正解なら正解にすべき
せめてルール通りではない箇所ワーニング出すべきだ。
