Nonograms Katana: Sharpen your mind!

Nonograms, also known as Hanjie, Griddlers, Picross, Japanese Crosswords, Japanese Puzzles, Pic-a-Pix, "Paint by numbers," and other names, are captivating picture logic puzzles. In these puzzles, players must color or leave blank cells in a grid based on numbers provided at the grid's edges, which ultimately reveal a hidden image. These numbers serve as a form of discrete tomography, indicating the count of unbroken lines of filled-in squares in each row or column. For instance, a clue like "4 8 3" signifies groups of four, eight, and three filled squares, respectively, separated by at least one blank square.

Solving a Nonogram requires determining which cells to fill (referred to as boxes) and which to leave empty (referred to as spaces). Marking spaces with dots or crosses is crucial, as it helps in understanding where a clue's block of boxes may extend. It's essential to rely solely on logic and avoid guessing; a single incorrect guess can spread across the entire puzzle, ruining the solution.
