Normal sudoku rules apply. Digits touching the outside of a Blue cage on all orthogonal edges (but not touching diagonally) must sum to the indicated total. Digits touching the outside corners of a Green cage (diagonally, but not touching the cage orthogonally) must sum to the indicated total. Digits touching the outside of a Red cage both orthogonally and diagonally must sum to the indicated total. No repeats are allowed in the digits making up the totals.
