Simple app that is as advertised This is a fun little game that will keep you guessing. Every puzzle is different (or at least it seems that way :). There's no sound, which is fine by me, & they don't ask for ridiculous permissions. I give it it 2 thumbs up.
Glad Guy I love it! The variety, the high scores, and the fun! Get this app!:-)
