### 2/5 — There is a timer

*2026-08-08, version 38*

Good game but time is stressful

### 3/5 — Great game, but I spent more time watching ads than playing.

*2026-06-29, version 2.4*

I get that you want us to purchase the full game without ads, but geez. Every wrong move is a 30 second ad. When you throw a hard level out there, I’m watching long ads on repeat. I just don’t have the patience. Total frustration. Please fix it because I love the actual game.

### 1/5 — Enjoy it

*2026-04-23, version 2.4*

You love commercials knack your self up!

### 4/5 — Decent got a game to play when your bored

*2026-02-20, version 2.4*

Prolly the most decent game I’ve played tho it can be a bit hard that’s the only down side

### 5/5 — Petie

*2025-11-21, version 2.4*

I like 👍 it

### 1/5 — Insufferable!!!

*2025-09-23, version 2.4*

Ads are INSUFFERABLE!! Ads to gain an extra hole, ads to move on between levels, ads for restarting, ads ads ads for everything! Deleting!! Horrible set up. Very disappointed

### 2/5 — Needs work

*2025-09-17, version 2.4*

I’m on level 636 and every 10 levels, they let you spin a wheel for a prize that includes tickets, bolts, plates - - tell me why I’ve never won a ticket? Other than that, you can win a prize and it won’t let you claim it so that’s def a bug that the app needs to fix. You have to watch ads galore. It’s a pretty fun idea, but the app itself can be frustrating


UPDATE: Took a break from this game for a while, found that they fixed the bug with the wheel but now there’s a new bug that says you win prizes if you go on a streak and after a certain level, those prizes never show up on the account despite being given. Also, the ads are like worse than ever. It makes me want to throw my phone away now insufferably long they are. Do better.

### 1/5 — Eff this game

*2025-09-17, version 2.4*

This game is stupid hard from the jump. Hope you like ads, cause they shove them down your throat even when you win!!!!!

### 5/5 — Logistics game

*2025-09-07, version 2.4*

Which hole are you gonna pull? Where are you gonna put it? Where is the screw gonna go? Which way is the board gonna fall find out?

### 1/5 — Where are my 19 coins

*2025-07-31, version 2.4*

No coins
