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.

Only issue with this game is that it routinely loses my progress when switching devices. A plus though, is that it uses a shortened version of ads that you can skip pretty quickly. I'd pay to have the ads removed, but considering that it loses my progress all the time, I'm worried it won't be a one-time purchase.
