User Reviews

Overall quite good, but I wish filtering functionality were better. It’s not clear how the filter toggle buttons interact—it would be great to have explicit include/exclude or and/or control. I would also love to be able to filter size by one dimension. On mobile, I much prefer tall/narrow puzzles to short/wide, and I’m not aware of any way to specify that (such as max width). A second-best capability would be a rotate/transpose option.

Ads don’t close. They lock up and the app has to be hard closed, then reopened. Ad rewards not awarded. Even worse, it opens to an ad, so you can’t get past it to the game. Completely broken.
