Nonogram (also called Japanese puzzles, Hanjie, Picross, Pic-a-Pix or Griddlers) is a logic puzzle: the sequences of fields, whose length and order are given, must be blacked out to reveal the secret image (the pictogram).
Each number on the lines outside the grid represents a block of boxes in that row or column that is being shaded (or colored).
- Each numerical value corresponds exactly to the length of a block.
- If there are several numbers, their sequence corresponds to the order of the blocks.
- There must be at least one empty box between two blocks of the same color.
- There may or may not be an empty box between two blocks of different colors.
If, for example, the numbers 3 2 3 are in front of a line, then within this line there is first a block with three blackened boxes, then a block with two blackened boxes and then a block with three blackened boxes. There must be at least one empty box between two blocks, which is not blacked out but ticked.
Here is an example with solution techniques.
The nonogram game improves perception, concentration, logical and visuo-spatial thinking. Print, color, play and have fun!
