Incredibly addictive!! And good exercise for the brain The free version does have ads, but they're for other games, are very short, and aren't so frequent as to be annoying. (Very rare!) However, I'm going to upgrade anyway because these guys (Kritanix) do such a great job with their other app (Jigsaw Puzzle Epic), have been very responsive on the few occasions I emailed with questions, and, hey, GOOD software development isn't easy. Given how well they do, they deserve to be paid IMHO.

Originally I liked this game. It worked well, with no problems. I didn't mind the ads, they were unobtrusive and easy to ignore. But now it has switched to autoplaying unskippable video ads. And after the timer on 1 runs down, a 2nd comes up on the next page. Dear advertisers, unskippable ads will ensure I remember your product, so I can NEVER use it. Go back to the non autoplay ads that eat up my time and data, and I will give a better rating.

A good app, with a problem: if you have some numbers pencilled in, and you decide to try a possibility just to see if it pans out, if you want to go back and erase the number, the pencilled numbers will also be erased. Trying out a possible number is a key tactic, and if you lose the pencilled numbers, then you cannot apply it. With this design error, the app cannot be used.
