### 2/5 — Ok Fun, but limited due to cost

*2025-02-25, version 1.10.2*

The cost model is outrageous.  You only get to play 1 level per section, without paying for the section.  It’s incredibly expensive per game.  Shame.  I’ve beat all the games and will delete the app

### 5/5 — ふつうにめっちゃおもしろい

### 5/5 — いい暇つぶし

*2024-02-25*

シンプルで良い

### 5/5 — 進化してる

*2023-10-19*

昔やってたんですよ。その時は簡単だし問題も少ないしですぐ終わってしまってアンインストしたんですね。何年ぶり？かでやってみたくなり再インストールしたのが昨日です。 問題増えてるし難しくなってるしでハマりますね！昔の購入履歴が残ってたようでグリーン1をやっている所です。
追記:
グリーンは難しくてブルー買いました(笑)そのうち全部買うと思います。
一手前に戻る機能が実装されると嬉しいです。

### 5/5 — Pretty close to perfect, buut…

*2022-02-16, version 1.9.1*

Arguably too expensive… I’ve bought more than enough packs at 99¢ each that if I get bored replaying them, I’ll just delete the game for awhile; I can’t justify spending any more cash on this very simple game.

The only complaint regarding gameplay is that if I restart a level, the marks I’ve made in cells to designate “No Bulb” are cleared, and I have to go thru that whole process again — which can be a lot on certain levels. This should be a second, optional clearing determined by the player.

Otherwise, very fun, easy-to-mildly challenging puzzle game I can easily revisit over time.

### 5/5 — ？

*2020-06-21*

とても、面白いので楽しんでいます。
前に、美術館(?)という名前の同じゲームをしていました。
紙だと、書いたり消したりするのは不便ですが、携帯なら指でタッチするだけなので簡単です。
数独も大好きですが、数独より携帯にピッタリのゲームと思います

### 5/5 — 久々にいいゲーム

*2020-05-20*

シンプルでハマるゲームです
考える心地良さもある
広告も邪魔にならない

### 4/5 — いい感じ

*2020-03-16*

ゲームも良く、広告も少ないです。が、一手戻る機能があればいいかと
