### 5/5 — Super simple and effective

*2025-07-19*

I’ve been using this app for years and it’s very straightforward and easy to use. The higher levels are definitely extremely challenging. If any improvements were to be made, I would say that more intermediate levels would be helpful, as well as options to change the background, pillar shape/color, etc. Great app, as is!

### 4/5 — 間が欲しいです

*2022-05-08*

とてもいいアプリです。毎日トレーニングに利用してます。レベル2と3の差が大きいので間にもう少し易しいレベルがあるといいなと。全部で7段階くらいあると嬉しい。

### 2/5 — Slow it down a tad

*2021-05-18*

This app moves to fast. The levels change too dramatically. It goes from level 0 (which I can do easily) to level 1 that I can barely make out 2 numbers out of the 4. You should gradually increase the speed so people can better train their eyes. All this app does is frustrate me. Hopefully there’s an update to fix this issue. Thanks for listening

### 4/5 — バグ報告

*2020-12-10*

空白で回答すると、数字並びが逆で表示されているようです。

### 2/5 — お試し版と比較して

*2018-03-19*

お試しの難易度2.5が本ゲームの最高難易度4に匹敵していると感じます。自信がある方は購入せずに体験版をプレイして、2.5がある程度読めるのであればそちらを完璧に読めるように極めた方が良いと思われます。

### 5/5 — とてもいい👍

*2015-05-31*

1回ごとに答えを入れずに次々と飛んでくるようなモードも追加して欲しいです！

### 1/5 — アップデートでなおしてー

*2012-05-10*

細くなっていって数字読めない
買わない方がいいですよ
金の無駄ですよ

### 5/5 — あっがれーヾ(＠⌒ー⌒＠)ノ

*2011-01-23*

やればやるほど上がるのがいいね(o^^o)

### 2/5 — 面白いが…

*2010-07-14*

面白いアプリで楽しんでいたのですが、六角柱が細長くなってしまい、数字が読めないような状態になってしまい元に戻りません。

### 4/5 — 面白いです。

スコアが56だったんですが、これは、どうゆう評価をすればいいですか？

評価基準値があると嬉しいです。
