Z-Rox is a new puzzle game being promoted by SmartKit. The game asks you to identify a given letter, number, shape, or symbol but all it shows you is a single line cross-section as it moves from top to bottom–like a copying machine. In order to not make it too easy, the line always stays in the same place. There seems to be 100 different puzzles currently for the game. I haven’t gotten through them all, but when I got to 50, the game told me I was half way there. Enjoy!
