User reviews

great game but

amazing game with no ads and fun way to kill time however there’s bugs with the master levels that include the question marks. when you fill it out sometimes it won’t say that you solved it one of them is level 144x

Very enjoyable, with some road bumps

The game is smooth and consistent until around puzzle 144. I had to redeem points for hints to do the entire puzzle for me because although I correctly filled out all of the boxes it wouldn’t count the puzzle as solved. I’ve hit the same problem with 152. Overall the game is great, but some of the “master” level puzzles with ?’s are broken.

Love the Game, No Ads, Minor Glitches

Like other reviewers, I absolutely love this game. It’s something to pass the time and no ads makes it much better than most! However, there are minor glitches when solving master level puzzles.

Kudos to the developer on this amazing game!

Buggy! Best part, no ads

The sound won’t mute — annoying. Worse, though, the app won’t acknowledge viable solutions to some of the games — and if you exit the level, it deletes your moves and resets the level. I’m stuck on level 136, which I’ve solved at least twice, but the app says I haven’t (I have a screenshot that proves it). I tried contacting support but the email address doesn’t work.
Also if you try to use a hint, it’s almost impossible to see what the hint was — it just blinks and disappears. I do love the lack of ads though.

Perfect

This app was exactly what I wanted. A good game with great UI, zero micro transactions, and no ads. Truly perfect in every way. Being able to unlock new themes and stuff is amazing as well. Easy 5 stars.
