Normal sudoku rules apply.

Draw an orthogonally connected loop that does not branch or cross itself. A loop segment is a string of cells between 2 loop corners and it includes the corners. The sum of the digits on a loop segment must be divisible by every digit on that segment.

An arrow counts the number of loop cells in the indicated direction and its off the loop. Box borders divide the blue line into segments of equal sum. An inequality sign points to the smaller digit.
