Friday Puzzle #57 - Two by Four Winds
Rules: Draw one or more horizontal or vertical lines from each numbered clue so that all blank cells are connected to exactly one of the numbers. Lines cannot enter other numbered squares or intersect with other lines. Each number represents the total number of blank cells occupied by the lines from that number. Some clues are shaded in gray and are shared between the two grids; these values (10 or 20) represent the total number of cells connected to the number in that exact position in both grids (ie a 10 clue might have 4 cells in one grid and 6 in the other).
