Nonogram

Japanese crosswords, also known as nonograms, are a highly engaging form of graphical puzzle that enhances logic, abstract thinking, and knowledge. In this type of puzzle, numbers are used to encode a specific image. The goal is to fully reveal this hidden picture. The figures placed along the left side and top edge indicate sequences of filled cells (contiguous blocks with no spaces) for horizontal and vertical directions, respectively. The sequence of these digits dictates the order of the blocks, though their exact starting and ending positions remain unknown (figuring out where they go is the core challenge). Every number stands for an individual block of that specific length (for instance, a 5 indicates five adjacent shaded squares, while a 1 indicates a single shaded square). At least one empty cell must separate any two blocks within the same line.
