The object is to drag the ribbons from the top and from the left to satisfy the conditions.
See the very small colored squares in the intersections? Those are the conditions. They indicate which ribbon should be on top. But they're too small for me!
I did the 2x2 levels and most of the 3x3 levels. Never got to the 4x4 or 5x5 or 6x6
