### 1/5 — Worst app ever

*2026-08-23, version 1.2.9*

This is the first game I have ever played. You can’t get through a level without watching 30-50 ads. After every 7-8 moves an ad pops up. Even if you select no thanks to a bonus the ad plays anyways and it doesn’t give you the bogus. I was only playing it to get a reward in another game but it’s not worth it. Not fun at all.

### 4/5 — Double Number Merging

### 3/5 — Love it, but too many ads

*2026-08-01, version 1.2.9*

This is such a relaxing game where time flies, but there are ads every few moves. It’s off putting. Ads between levels and to earn perks/upgrades would be much better

### 1/5 — Too many adds

*2026-07-07, version 1.2.9*

A pop up add every 30 seconds or so makes it totally unplayable

### 1/5 — Too many ads

*2026-05-19, version 1.2.9*

The ads make this otherwise fun and addictive game just annoying and bothersome to play

### 1/5 — Review

*2026-04-27, version 1.2.9*

The number of ads genuinely makes the game unenjoyable.

### 1/5 — Scam

*2026-04-08, version 1.1.0*

Scam scam scam don’t even download it. Sucks the life out of your data. It comes off as sponsers for other game to get in game currency and it’s absolutely a scam. Wasted days of my life with endless ads and they accuse me of malicious practice because they don’t want to hold their end of the bargain. Dont do this for free in game rewards as a sponsor SUPER SCAM!!

### 1/5 — Ads

*2026-03-17, version 1.1.0*

Horrible game combined with nothing but Denver couple of seconds

### 1/5 — BEAUCOUP TROP DE PUB

*2026-02-07*

le jeu en soi est bien, mais le fait qu’il y ait énormément de pub est horrible. Toutes les 10 secondes il y a une pub. C’est même pas possible de jouer au jeu tranquillement. Autant mettre des pubs après chaque fin de niveau mais même pendant un niveau t’as au moins 30 pubs
