### 1/5 — Stuck at 205, can’t advance beyond 205

*2026-06-24*

This game is defective. Will not allow progress beyond 205. I merge 205 expecting to work 206 through 210, but it’s 201 to 205 again. It’s happened 3 times now. The game is broken. Please respond!

### 1/5 — Stuck at 205, can’t advance beyond 205

*2026-02-03, version 2.3.7*

### 1/5 — Ads galore!

*2026-01-05*

The game itself is fun, but the ads are ridiculous. First you watch an ad, then a little pop-up static ad, then you watch another ad, and then two more pop-ups. And the ads come up fairly often. I played once before I deleted the app.

### 1/5 — Un-AD-pla-AD-able

*2025-08-09, version 1.1.4*

Unplayable. An ad every 30 seconds (if you’re lucky. I got one 2 seconds after one) I understand you need to make money off a free app but this is ridiculous.

### 3/5 — Game doesn’t want to load

*2025-08-03*

I have the same problem. It turns black and it doesn’t want to load. I don’t wanna delete it because I’m way advanced. I need a solution.  Maybe an update????

### 3/5 — Good game but too many ads

*2025-07-14*

It’s a great game! But every time you merge 5 to get 6 it plays two ads. And there’s no way to pay for ad free gaming. Gets annoying after a bit.

### 2/5 — Ads

*2025-07-07*

Very fun game it’s just to many ads, I didn’t have a problem when I first downloaded it but now I keep getting them every second, I deleted the game because of to many ads

### 1/5 — Moves you down level/rank

*2025-07-04*

Was exited to be on level/rank 100 (I was on 90-95) I finished it and was expecting to be on 95-100 but ended up back to 80-85? How does that happen? Why did I go down instead of up? So dumb, I maybe it’s cuz in the ranking it only shows up to rank 100 and I was close to that and it would be the end of the game?
