Introduction and Instructions
"Nonograms, also known as Hanjie, Paint by Numbers, or Griddlers, are 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 of filled-in squares there are in any given row or column. 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." (source: Wikipedia).
The first Nonogram I saw (in Switzerland) was published in the Tages Anzeiger end of last year.
The numbers in front of the rows and columns define the size of the blocks to find. Every number matches the size of a block to find. When more than one number is indicated, they are listed in the order of appearance of the blocks. At least a space of one cell must exist between two blocks.
Start with the biggest blocks. Search for other overlaps. Compare the number of completely filled out blocks and place crosses on cells found to be empty. Strike the numbers corresponding to found blocks. And if you're out of luck, try out the alpha version of the "Hint" section.
