In 1986, Non Ishida, a Japanese graphics editor, won a competition in Tokyo by designing grid pictures using skyscraper lights which are turned on or off. Meanwhile those picture logic puzzles are among the most popular puzzles in the world. They were named NONOGRAMS after Non.
At Nonograms, cells in a grid have to be colored or left blank according to pure logic to reveal a hidden picture. The numbers, given at the top and left border of the grid, measure how many unbroken lines of filled-in squares there are in any given row or column. To solve a Nonogram, you need to determine which cells are going to be boxes and which are going to be empty. It is also important never to guess. Only cells that can be determined by logic should be filled!
A comprehensive guide with lots of hints is included in game and in the attached manual.
