Nonogram are the 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. In this puzzle type, the numbers measure how many unbroken lines are to be filled-in squares there are in any given row or column. For example, a clue of “4 8 3” would mean there are set of four, eight, and three filled squares, in that order, with at least one blank square between successive groups.
Each puzzle has blank grid with clue on left of every two and on top of every column. You need to place block by click on the grid cell to unhide hidden picture in such a way that each row and column color block length and sequence is corresponding to the clues and there is at least one empty square between adjacent blocks.
Nonograms – The game is known by the names of Hanjie, Griddler, Picross, Oekaki, Logigraphe or Crucipixel depending on the county.
