I really like the game play itself with this app, but admittedly the apps are getting obnoxious. the usual was 1 ad in 5 minutes, which is fine. But you get pop-ups that can result in an ad, you'll get moved to a different screen with an ad, then penalized for leaving the app by watching an ad. They've become much more abundant since I first downloaded the app, and I'm tempted to get rid of it.

Ad simulator. Holy Ads Batman! if it were just a short ad between games, sure. but requiring ads in between every game AND having ads in the middle of the game is excessive. 0/10. would not recommend. it's a waste of time and there are tons of better sudoku apps out there. If you downloaded it for another apps rewards, I promise it's not worth the time it takes.

Would be an average rating, but the ads that supposedly support the app being free are run in the MIDDLE of you attempting to complete puzzles as opposed to the beginning (before the timer starts) or the end of the level like EVERY OTHER TIMED PUZZLE GAME. Seriously. it takes your lovely 3 minute puzzle time and pushes it out to 5 minutes because the ad doesn't pause the timer. Oh no. You have to deal with the fact that unless you subscribe and pay real money, your time will always be ruined.
