Normal Sudoku rules apply.

Double arrows are mirrors.

Cells on either side of a mirror add up to the same total. The number of cells taken into account for the sum depends on the color of the mirror.

The grid is toroïdal, so:
The sums of r2c1-4 and r2c6-9 are equal and
the sums of r1-2c9 and r8-9c9 are equal.

Some possible mirrors are not given.

Finally, the product of the shaded cells in row 1 is equal to the product of the shaded cells in the central region.
