Rules:
Normal sudoku rules apply.
The grid contains a single region sum line (RSL) that moves orthogonally throughout the grid. The line may not intersect nor overlap itself. (Digits on a region sum line have the same sum in each box the line is in. If the line passes through a box multiple times, each individual segment sums separately.)
All blue shapes are on the line and all red shapes are not.
The line begins and ends on the diamonds. A square equals the number of cells on the RSL in that box. A circle equals the number of RSL segments in that box.
