I love this game so much! I've played over 320 levels. It is challenging in the beginning but once you notice some patterns, it's super easy (I still mess up sometimes). The ads aren't that bad but getting pop-ups in the middle of levels is a bit annoying. Especially if you keep losing on one level and have to watch ad after ad when restarting.

Should have taken more time to read reviews. It's a fun game, but after a short honeymoon period they interrupt game flow to play ads mid-level. I tried a few levels to see if it was only happening during daily puzzles or what, but it happens during all puzzles. Super annoying and I have un-installed it. I can deal with ads between levels, or if you exit off the screen/pause, but ads while you're actively playing a level? Awful.

First off, I enjoy the math puzzle aspect of this game. That said, I absolutely hate that it often interrupts me in the middle of a level for an ad. When I'm in the middle of marking or clearing multiple cells, it's infuriating and very disruptive to my thinking to have an ad pop up right then. Now I see that others have complained about this for months and it hasn't been changed, so I'm changing my rating from 3 to 1.
