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

Fun, but can’t turn sound off

I really like this game, lots of fun and relaxing, but can’t play it while listening to audio books/postcasts etc as the “sound off” toggle doesn’t work and the app always has sound which stops playback from other sources on my phone :(

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!

Great game but…

Why does it not show as the game is completed when the grid is actually complete?
In the UNLIMITED MODE, I think there’s a bug as it does this all the time.
Also, there are grids that as soon as they are displayed to start playing, I’ve noticed that some squares are IMPOSSIBLE TO FILL. I have a picture of this!
Also, another irritating bug is that when you play with sound checked off, it still plays a sound when you complete a block which means that if you want to listen to music while playing in silent mode, you can’t listen to music!!!
3 stars because of that!
