Incredibly addictive!! And good exercise for the brain The free version does have ads, but they're for other games, are very short, and aren't so frequent as to be annoying. (Very rare!) However, I'm going to upgrade anyway because these guys (Kritanix) do such a great job with their other app (Jigsaw Puzzle Epic), have been very responsive on the few occasions I emailed with questions, and, hey, GOOD software development isn't easy. Given how well they do, they deserve to be paid IMHO.
