    Tried downloading it again. Still a ridiculous amount of ads just to play a puzzle, and they are absolutely intolerable ads. Don't give me that rhetoric about being needed to be a free game. That can be done without THAT many ads. A lot of people choose to watch extra ads for help. You don't need to force several on someone for each puzzle.

    Great sudoku app. The ads are unbearable though. I get them in between every game and they are impossible to exit. I end up having to close the app and reopen just to play the next game because I'm stuck in an ad. On top of that, half of the the ads want me to play them to exit, then won't let me leave the app store. I usually end up just closing out the app and forget about it. If they don't fix this, I'll just uninstall. Please just let me leave the ads once I've watched it!

    It's pretty much like every other Sudoku game out there. Missing a feature I wish any of them had (color-marking squares, not just noting). Ads are not as pervasive as other similar apps, but it does do one thing very concerning — interrupting your game with an actual Chrome browser pop-up ad. These ads are often the kind that are common scams (such as claiming your device is infected).

    the games themselves are fun, challenging on the harder levels and i enjoy the games. But the ads make it hard to enjoy the games. Start a game, ad. Finish a game, ad. some ads make you go to the app store then exit to continue. There is no need for all those ads. I've read the comments and this is a common theme. I've read the responses saying they are trying to balance gameplay and ads. No way. no other game that I play has this many ads. One ad per game would be fine, not this many.

    Same experience as everyone else, there are way too many ads to make this game worth it. If I pause a puzzle, there's an ad to reload back in. There's an ad at the beginning of a puzzle and in between puzzles as well. I spend more time clicking out of ads than actually playing the puzzle. I'm downloading Sudoku.Coach since it's truly ad-free.
