### 5/5 — Knifflig und minimalistisch …

*2022-09-23, version 1.2.3*

…genau wie ich es mag, und ohne überflüssigen Schnickschnack und gänzlich ohne Werbung für nur 0,99€.
Es gibt 50 vorgefertigte Ausgaben mit wachsender Schwierigkeit und alternativ unendlich viele Aufgaben per Zufallsgenerator.

Das perfekte Spiel, bei dem man allmählich rauskriegen muss, wie es funktioniert.
Ideal für Leute, die nicht animiert werden wollen / müssen, sondern selbst eine Lösung finden wollen.

Einen Wunsch habe ich noch an den Entwickler: Es wäre sehr schön, wenn die Zahl der gebrauchten „Züge“ angezeigt und gespeichert würde. Dann könnte man sich auch noch verbessern.

### 5/5 — good

*2022-05-28*

good 👌

### 4/5 — A really good game

*2019-07-29*

Not enough lvl ! I m waiting for more ... 50 lvl are not Enough for a no free game !

### 3/5 — Example of why mobile puzzlers are often disappointing

*2019-02-27*

The solutions aren’t really clever or interesting, most of the game is tapping random stuff and hoping you stumble into the solution. A good puzzle should have a have a simple solution that when you see makes you go “oh that’s smart,” and the process of solving it should be centralized around a catch. But you don’t get many “wow that was clever” moments like that here, and the level design feels like not much effort went into it. Each level should have its own interesting idea to contribute, and solving each puzzle should be the player’s way of exploring those ideas. Of the few “Ah-ha!” moments this game has to offer, most of them feel as if they weren’t planned by the level designer, and the way you solve a level depends completely on how you decide to try it. When there are a countless number of ways to complete each puzzle, how can any levels be thought out fully? So although there are some moments of actual problem solving here, overall it’s not great. If you’re looking to tap random buttons, this is for you. If you’re looking for some real puzzles check out the witness...

Three stars because I understand making puzzle games can be very difficult. And as a puzzle game maker I’ve made games that had similar issues. Keep trying!

### 1/5 — Rip off!

*2019-02-21*

I know it’s only .99 but my kid wants instructions.. seems silly to be the game of the day when it’s pretty basic and not much to the game. What makes an app game of the day! Will definitely make me think twice before I buy anymore apps.

### 1/5 — Crap game

*2019-02-01, version 1.1*

Crap game and very boring.... no skill or logic in movement and design... don't bother!

### 4/5 — Smooth gameplay

*2019-01-27*

No tutorial, but easy enough to figure out. The game is very short, but addictive!  I hope to see more levels soon!  Worth the dollar for this game! 😁

### 5/5 — ちょうど良い難易度

*2019-01-22*

恐らく大抵の面は複数パターンでのクリアができ、少なくとも一手でも間違えるとアウトというのは無いはず。
その為、とりあえず押しながら考えられるのが良い。

### 5/5 — Awesome game,

*2019-01-21, version 1.1*

This is a great puzzle game that is so simply it’s ingenious.  However, the game won’t let me pass level 21 despite completion of the level.  Am I missing something?

### 5/5 — Great time waster

*2019-01-20*

Great way to waste some time but after two times through the game I feel like bored of it because there are only 50 levels.
