Another Detour
(Published yesterday, 16:00 by Blobz)
Normal sudoku rules apply.
Draw a loop (using orthogonal line segments through the centers of cells) such that it visits every cell marked with a diamond. The loop may cross itself, but can only change direction (turn through 90 degrees) at a diamond. Thus, all "corners" of the loop are on diamonds. However, not all diamonds mark loop corners -- "non-corner" diamonds lay on a line segment _between_ two corners.
The loop has a specific direction, such that each digit in a "corner" diamond equals the number of cells needed to move along the line segment to reach the next corner. Each digit in a "non-corner" diamond must equal the sum of the two corner cells of its line segment.
