Mirror Paradox

- Normal sudoku rules apply.

- Negative diagonal: Digits must NOT repeat on the marked diagonal.

- Reflected cages: The marked diagonal also indicates a line of reflection for the grid. All cages are reflected across this line. Reflected cages have the same sum as the original cage. For example, if there was a 5-sum cage containing R4C1 and R4C2, then there would also be a 5-sum cage containing R1C4 and R2C4.

- Anti-reflected digits: Digits must NOT repeat in their reflected cells. For example, if R2C8 were to contain a 3, R8C2 could not contain a 3 as well.

- Killer cages: Digits in cages must sum to the number in the top-left corner (if given) and cannot repeat. Where a number is not given, the cage and its reflected cage both sum to x, where x is to be determined by the solver. To clarify, x is the same for pairs of reflected cages, but not necessarily the same for all unmarked cages.
