All puzzles tested by computer program and have unique logical solution If guessing, a single error can spread over the entire field and completely ruin the solution. Only cells that can be determined by logic should be filled. Solvers usually use a dot or a cross to mark cells they are certain are spaces. Later in the solving process, the spaces help determine where a clue (continuing block of boxes and a number in the legend) may spread. Determining which cells are to be left empty (called spaces) is as important as determining which to fill (called boxes). To solve a puzzle, one needs to determine which cells will be boxes and which will be empty. For example, a clue of '4 8 3' would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive groups. The numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column. Nonograms, also known as Hanjie, Griddlers, Picross, Japanese Crosswords, Japanese Puzzles, Pic-a-Pix, 'Paint by numbers' and other names, 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.
