Griddlers logic puzzles, also known as Picross or Nonograms, are picture logic puzzles in which cells in a grid have to be colored or left blank according to numbers given at the side of the grid to reveal a hidden picture. Some people compare Griddlers to Sudoku. However, the Griddlers puzzles always reveal a nice image as a result.
