### 4/5 — Great game but…

*2025-07-09*

I really like this game. I just wish they would create games more challenging than Hardcore.

### 5/5 — 다 좋은데 발열이 심하네요

*2025-03-27, version 2.7.0*

아이패드로 플레이하는데 게임은 재밌는데 발열이 심해요

### 4/5 — 難易度が物足りない

*2025-01-16, version 2.7.0*

歯応えのあるパズルゲームを求めてインストールしましたが、ハードコアモードでもいささか難易度が物足りないです。線が交差する回数に制限を設けるなど、さらに難しい問題の開発を期待しています。

### 5/5 — ご褒美にヴァリエーションが欲しい

*2024-06-17, version 2.7.0*

楽しいゲーム！脳の体操に最適。じっくり取り組めます。
でも完成時の盛り上がり効果が平坦なので、そこだけちょっと不満でしょうか。
まあゴール出来たらとっても満足しちゃいますけど…

### 5/5 — Better than good

*2023-12-23*

Very good

### 5/5 — Challenging game

*2023-09-29*

I really enjoy playing this game. There are a lot of boards at multiple levels and a daily challenge. I would like the developers to add an undo button as well as an option to get back to the menu instead of having to press the Give Up link. While it doesn’t count against the number of boards completed, it displays a new game. An option to save game would also be nice.
