Normal sudoku rules apply.
Each number next to a row refers to the square with a “9” in that row, and is the sum of all squares that are orthogonally adjacent to that square. Each number above a column refers to the square with a “8” in that column, and is the sum of all squares that are orthogonally adjacent to that square.

Beauty and the Beast!!!
That was the craziest puzzle I have ever solved (especially to show uniqueness). The sums on the sides are not that hard, but the symmetry does make this quite tough. I have no idea how you set this beautiful monster :-)
