It's a nice puzzle game, just not for me. I like doing physical puzzles a lot better. You can see all the pieces at once and sort them into piles and colors. This app shows all the pieces in a line that you have to scroll through, all mixed up and it's not very practical. At least it allows you to sort corners and edges together, but meh; still unappealing to me. Also, ads show up in the middle of doing a puzzle randomly and that kills the peace. An okay app, but not my favorite.
