PUZZLE
RULES
Sudoku: Normal Sudoku rules apply; place the digits 1-9 once in every row, column, and 3x3 box.
Loop Construction: Construct a one cell wide, closed loop of orthogonally connected cells around the grid. The loop may not touch itself in any way.
German Whisper Loop: Adjacent digits along the loop differ by at least 5.
Diamonds: The 3x3 box borders divide the loop into segments. Cells with a diamond are on the loop and count the length of the segment it's on in that box.
Exceptional Circles: Cells with a circle are on the loop, but are excepted from the German Whisper constraint. The same digit is in both circles.
