A Crossdot puzzle starts as a grid of empty cells. Your goal is to find the hidden picture, using logic to determine which cells to color. The numbers outside the grid are clues that help you figure out what to color in each row and column.

This popular logic puzzle is known by many names, including Nonogram, Paint by Number, Griddler, Picross, Pic-a-Pix, Hanjie and many others. To add to the glorious chaos we’ve chosen our own name: Crossdots.

We offer a wide range of puzzle sizes. Some might prefer to use an iPad for the larger puzzles, and we totally get that. But if you don’t have an iPad, worry not. With Crossdot’s unique locking mechanism, we’ve found that we can conquer any size puzzle, even on the iPhone or iPod Touch. Go ahead and give it a try.

Good luck and have fun!
