What is a Nonogram?
A nonogram (also known as Picross, Griddler, or Paint by Numbers) is a logic puzzle where you fill in cells on a grid to reveal a hidden picture. The numbers along each row and column tell you how many consecutive cells to fill in. By using logic and deduction, you can solve the puzzle without any guessing.
