In 1987, Non Ishida, a Japanese graphics editor, won a competition in Tokyo by designing grid pictures using skyscraper lights which are turned on or off. At the same time and with no connection, a professional Japanese puzzler named Tetsuya Nishio invented the same puzzles.
This is the basis that CrossPix is based upon, these puzzles are also known as Paint by Numbers, Griddlers, Pic-a-Pix, Picross, Prisma Pixels, Hanjie and many others.
