Nonograms play online

Nonograms, also known as Japanese Crosswords, Paint by Numbers, Picross, Griddlers, Pic-a-Pix, Japanese Puzzles, and various other names, are picture logic puzzles. Numbers on sides are clues to solve the puzzle. They indicate sequences of painted squares separated by at least one blank square.
The nonograms can also be multi-color. In this case sequences of different color may or may not have spaces between them.
