User Reviews

Reviewers generally praise the puzzle’s relaxing, strategic gameplay but are overwhelmed by advertising practices. While the core concept is fun and engaging, frequent and lengthy ads—often after every level—along with misleading claims of no ads or offline play and paywalls to remove ads or unlock moves heavily detract from the experience. A few note occasional frustrating level design or being forced to repeat levels. Overall, solid when ads are minimal, but the ad model dominates user satisfaction.

Pros

Fun, relaxing puzzle with engaging and occasionally addictive gameplay.
Challenging, strategy-based mechanics that reward thoughtful moves.
Overall enjoyable game with a solid core concept.

Cons

Ads are excessive and intrusive: frequent interruptions and long durations.
Advertising claims are misleading (no ads and offline play) and not respected.
Progression often requires watching ads or paying, creating a paywall and hindering advancement.
Some levels feel frustrating or repetitive, leading to stalled progress or unsatisfying progression.

Recent reviews

This is one of those games that only allows you to get halfway through a level Before you get stonewalled and the only way out is to either pay for some booster or watch a commercial.

The game was pretty fun but I found that every time I needed a little help or accidentally put a couple colors onto the board that I didn’t mean to then I had to keep starting over or watch very long ads. It would be nice if I had to watch that long ads I would get more then a single tool. So I had to delete bc I am not playing games to watch one minute ads multiple times every time I play.

It was fun until after level 12. I had ads after each level passed. I downloaded this game because it said no ads. I’m deleting. I already have a bunch of games like this with ads I don’t need another one.
