### 1/5 — Ads ads ads

*2025-09-06, version 2.3.622*

I cannot play this game long enough to even get a feel for it, I make a couple moves then get an ad repeatedly.  It seems like the daily levels are impossible but honestly the ads make it unbearable to find out if I even like the game enough to purchase it.

### 1/5 — Ad trap

*2025-05-18, version 2.3.622*

Not fun, should have 1/10th the ads.

### 3/5 — Remove Ads Feature not working

*2024-03-29, version 2.2*

Hi, I enjoy the game but paid for the “remove ads”.

Unfortunately I am still having to view ads and so, I would like a refund. The app has double charged me.

### 1/5 — Scam

*2023-11-07, version 2.2*

I paid to get rid of the ads, and on apple it says I paid but on the app it said “no internet connection” and the ads never went away.

### 1/5 — Purchased no ads and went through but game keeps saying it can’t connect it

*2023-11-06, version 2.2*

Ads are very annoying so why not spend $3 to get rid of them. Too bad the game scams you and says it can’t connect the purchase. Keeps saying there is no connection but my WiFi works and the ads are still playing through WiFi so how is it not connecting my purchase.

### 5/5 — Good game but don’t buy ad block on it

*2023-10-30, version 2.2*

So the game in itself is a good time waster but the ad block does’nt work so dont waste money on it like i did

### 1/5 — Ads every 30 seconds

*2023-10-03, version 2.2*

Seriously, ads every 30 seconds. And if you pay for no ads don’t change phones because any time you try to redeem your purchase the app conveniently doesn’t have internet connection… But the internment works fine to run ads every 30 seconds.

### 1/5 — BIG SCAM

*2023-09-30, version 2.2*

I enjoyed the game but hated the ads so I purchased no ads for $5.99 or something like that, not only did I get $20 taken out but the game still has ads, DO NOT INSTALL

### 2/5 — Can’t play - ad per move

*2023-09-04, version 2.2*

At nearly an ad per move, game is near impossible to play. In the last 20 minutes, I have literally made a maximum of 3 moves before an ad. Note: Maximum. And notice, all the ads that play are advertising games that are ad free, literally drawing you away from merge defense and trying to force you to quit!!!
Developer: i can’t even transfer my progress between devices. Why would I trust that the ad free would transfer?

### 5/5 — Didn’t download

*2023-06-19, version 1.36.516*

I haven’t downloaded it yet
