Nonograms (also known as *Hanjie* or *Japanese Puzzle*) are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture.

Nonograms are picture logic puzzles that use a grid with numbers, generally along the top and left side, indicating how many cells are coloured in in that specific row/column. They can be solved using logic to eventually show an image in the grid.
