Picross 15X15 - Nonogram

Picross, also known as Hanjie, Griddlers, Nonograms, Japanese Crosswords, Japanese Puzzles, Pic-a-Pix, "Paint by numbers" and other names,
are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture.

**Game Rule**
The numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column.
For example, a clue of "3 8 4" would mean there are sets of three, eight, and four filled squares, in that order, with at least one blank square between successive groups.
