This was quite the puzzler. However, as another review says, extreme levels 9 and 10 are literally impossible.Perhaps there's a bug in the system where a tile is mislabeled, or maybe you have to do something crazy like using less than 27 mines and completing every tile requirement, but at least for level 9, all possible ways of arranging 27 mines fail to solve the puzzle. (The closest I got was one wrong tile or all tiles correct but both a row and a column with 4, and another row and column with 2.)

Great game. However, I feel like the last 2 levels on extreme are not possible to complete

I have almost completed every free play puzzle. I’m still working on extreme 9 because it’s challenging. All of the puzzles I have done are possible to finish. I can’t say anything about 9 yet but I’m betting it can be done as well.

I can’t play any music or podcasts while playing this game. You start a game, the ad pops up and turns off whatever you have playing. Close the ad, go to your music playing app and press play, go back to this game and the ad pops up again and turns off your music. Every time you switch from this app to another, when you go back to this one, the ads pop up.
