### 1/5 — I’m deleting this one

*2026-08-31, version 2.3.1*

1) It has ads. Many ads. 
2)Some of the colors are indistinguishable. Actual user testing would have made this obvious.

### 2/5 — Fun Game, Many Ads

*2026-08-29, version 2.3.1*

There are way too many ads.  For every level you play, you have to watch multiple ads.  Waste of time.

### 1/5 — Way too many ads!

*2026-08-28, version 2.3.1*

This is a fun game, but you literally cannot get through even one level without watching at least two ads. It’s ridiculous! I’m looking for a different app.

### 2/5 — Stupid

*2026-08-26, version 2.3.1*

Why are there five empty slots when you can only use 4?  Why does the game end when you put a screw in the fifth spot even though you can keep playing?

### 1/5 — Not like advertised

*2026-08-22, version 2.3.1*

Says no ads but there are and game doesn’t look like it’s advertised either

### 1/5 — Ads ads ads

*2026-08-21, version 2.3.1*

Ads ads ads and game is set up to make you lose the level each time so you can watch more ads. Want to revive? WATCH AN AD! No? WELL WATCH AN AD ANYWAY!

### 2/5 — Amateur

*2026-08-14, version 2.3.1*

Why are there 5 empty slots when you can only use four?  Why does the game end when you put a screw in the fifth spot even though you can keep playing?

### 5/5 — Well Made Game

*2026-08-12, version 2.3.1*

The game is well made. It does not freeze and flows nicely. The game does include ads but not too many. The ads are not long and work properly. The game is not greedy and you really don't have spend money to get ahead. It is fun, challenging, colorful, and relaxing. Enjoy!

### 1/5 — Versprechen gebrochen

*2026-08-09*

Ab ca. Level 8 kann man das jeweilige Level nicht mehr beenden, ohne Werbung. Das ist Verar§che hoch 3. Wird sofort wieder gelöscht. Die in einem anderen Spiel zum Anlocken gezeigten Szenen entsprechen auch nicht dem Spiel. Lasst bloß die Finger davon

### 1/5 — einfach zuviel werbung

*2026-08-08*

ein schönes spiel das leider durch ständige Werbung kaputt gemacht wird. ich kann verstehen das die Entwickler Geld verdienen wollen. Aber mehr Werbung als Spiel ist die falsche Einstellung. ich hab es wieder gelöscht.
