Hidden Disjoint Magic

Rules:

1. Standard: Normal sudoku rules apply.

2. Disjoint groups with magic group: Cells in the same relative position of each box (e.g. R1C1, R4C4) must have different values. This forms nine disjoint groups (e.g. the first group will consist of cells R1C1, R1C4, R1C7, R4C1 etc.). One of these groups is a magic group, where the "rows" (e.g. R1C1, R1C4, R1C7), "columns" (e.g. R1C1, R4C1, R7C1) and "diagonals" (e.g. R1C1, R4C4, R7C7) all sum to the same total. The solver must determine which group is the magic group.

3. Standard killer: Cells in cages must sum to the cage total.

4. Standard XV: Cells separated by a X must sum to 10, and by a V must sum to 5. Not all possible Xs and Vs are given.

5. Standard kropki: Cells connected by a white dot must be consecutive. Not all possible dots are given.
