Secondary update: I would have been ok with a small non-intrusive banner ad, at the top or bottom of the screen. But a full screen ad, after every puzzle, from a developer that once said, free and ad-free? I may have been ok with $5 - $7/year to remove ads, $15/year, no freaking way. Congratulations you just ruined your platform. Truly no ads! Please keep it this way. The daily challenge puzzles are great as well.

Dear User, we added only one short ad between game sessions after you finish the puzzle. At this point it was a matter of project survival and continue development. We did our best to cut the ads to the absolute minimum among the other similar apps. Our apologies.

Loved this for a while, when there were no ads. Now there are, after every game. Just got one I couldn't even skip, had to just use the back button after I realized it wasn't going to give me a button to skip/close the ad. That just earned a bad review. Second star is only because the app itself is pretty good. The ads totally ruined it though, sadly.

Best Sudoku app! Great controls and different color schemes. There are no ads, but you can choose to give money to the devs. EDIT: The latest version of the app introduced ads and there is no good payment option for removing them (subscription only). Dropped my 5 star review to a 3. Still a good app, but now there are ads even if you have given money to the developers in the past.
