NonogramZ Pro is a Nonogram game, also called Griddler, Picross and many other names depending on region and variant rules. NonogramZ offers tons of puzzles following different themes that you can solve on a variety of devices. It also offers a special grid, ruler and other tools to make solving things easier (or harder). Though the puzzles have no unifying theme, there is lots of them, and although the extra tools do add a little clutter, they also change the game.
