The typical picross layout is a grid with numbers surrounding it. The numbers are clues to the picure you're gonna make. The numbers o nthe left give clues about the horizontal rows, the numbers on the top give clues about the vertical rows. The numbers tell you how many tiles are colored on that row, and how long the strings of colored tiles are. Enjoy and have fun beating all the puzzles, if you've beaten them all a special pack will be unlocked!
