Link-a-Pix
Link-a-Pix (also Paint-by-Pairs, Chain Puzzle, Pict-Link, Pathpix, Number Net) is a Japanese number puzzle in which you have to color a chain of boxes between the same numbers. The length of the chain between two numbers must correspond to the numerical value of these two numbers and the chains must not overlap. These colored boxes then create an image of black and white pixels , just like with nonograms .
Sometimes you will find a variant of the puzzle in which the numbers have different colors, with which the associated chains must also be painted. This is how colored images are created after the solution.
