Hall of Mirrors

- Normal sudoku rules apply.

- Diagonal: Digits must NOT repeat on the marked diagonals.

- Anti-reflected digits: The marked diagonals also indicate lines of reflection for the grid. Each cell has 3 reflected cells: a reflection across the positive diagonal, a reflection across the negative diagonal, and a reflection across both diagonals. Digits may not repeat in any of their reflected cells. For example, if there was a 5 in R2C4 then R4C2, R6C8, and R8C6 could not contain a 5. (The image below shows this more clearly).

- Killer cages: Digits in cages must sum to the number in the top-left corner and cannot repeat.

- For cells separated by a less-than or more-than sign, the arrow points towards the smaller of the two digits.

N.B. The green and red cells in the image demonstrate the reflected cell constraint. The cells in the actual puzzle are not coloured in.
