Nonograms — also called picross, griddlers or paint by numbers — are picture logic puzzles. Every picture on PuzzleWorld is randomly generated and checked by a solver, so it can always be solved by logic without guessing.
Easy puzzles are black and white. On medium and hard, two to four colours are used: each clue number is shown in its colour, and the colour bar below the grid tells you how many cells of each colour are still missing.
