Normal Sudoku rules apply.
Numbers outside the grid are the sum of the digits along the diagonal indicated by the arrow. Digits may repeat along a diagonal.
Small numbers within the grid are the sum of the digits within the marked cage. Digits may not repeat within a cage.
Additionally, there are three diamond shapes highlighted in the grid. For these shapes, the sum of the 5-cell cage within the diamond is the same as the sum of the 8 cells that form the perimeter of the diamond. Digits may not repeat within the cage but can repeat along the perimeter.
