Normal sudoku rules apply: Place the digits 1 to 6 in every row, column, and 2x3 box.
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.

There was only one possible path, so guessing will get you there, and getting to the correct path felt easy and intuitive

I am not sure but i think i only guessed, rather than solved, the path and got it right.
