User Reviews

Reviewers generally praise the puzzle concept and relaxing, brain-boosting gameplay across many levels. The major drawbacks are pervasive ads (including for users who paid to remove them), crashes/freezes that reset progress, loading issues after updates, and a desire for more difficulty control or level selection. The core idea is solid, but performance and ad experience require significant fixes.

Pros

Fun, engaging number puzzle that keeps the mind sharp
Relaxing gameplay with no time limit
Many levels to play and progress through
Brain-boosting math practice and mental calculation

Cons

Ads are intrusive and excessive (often between or even during games; long ads; appears even after paying for no ads)
Crashes/freezes that reset progress and lead to reinstall/loose data; support often unresponsive
Loading issues after updates (won’t load past the main screen)
Levels become too easy or lack difficulty controls (desire for adjustable level selection or harder puzzles)

Good game, when you get to play. I am fine with ads, but between every game? You play, you watch. Fun while it lasted, but I am deleting.

Ads are fine before or after a game. NEVER in the middle. I like the idea of the game but the implementation is horrible.

While the game had been enjoyable - fun enough to play many levels (& endure far too many ads) - the game has a crashing/freezing issue that began over the last few weeks. Attempted many issues to resolve, with the last resort being deleting & reinstalling (having to start over). It worked for one game session (6 levels), but the problems continue. Tried to contact support - but no reply. Too bad…have to permanently delete.
