The brief
Normal sudoku rules apply.
Digits in row 5 index the position of 5's in their column. Likewise, digits in column 5 index the position of 5's in their row. For example, if r4c5 is a 2, then r4c2 is a 5.
Digits do not repeat along the two marked diagonals.
Digits in cages do not repeat, and sum to the value given.
