Rules
Normal sudoku rules apply.
Orthogonally adjacent digits cannot sum to 5 or 10.
XY-Sums: clues outside the grid indicate the sum of the first X digits and last Y digits combined, where X is the first digit and Y is the last digit from that direction.
Solution code: Column 5

Very nice! A bit tricky to get started, but when the negative constraint shows its full power, it becomes very smooth. Thanks
