Paint by Numbers: use logic to solve our nonogram puzzles. Discover the hidden image in this Griddlers game. Color the grid and reveal an image on every level. At the top of each column and at the left of each row there are one or more numbers. These numbers tell you the runs of colored squares in that row/column. So if you see '4 1', it means there will be a run of exactly 4 squares in the indicated color followed by a single colored square. If the 4 and 1 have the same color then at leat 1 white square is between them.
