Rules:
- Sudoku: Fill all rows, columns and marked 3x3 regions with the digits 1-9 without any repeats.
- Doublers: There are 9 Doubler cells in the grid, one in every row, column and region. Every Doubler contains a unique digit and for the purpose of arrow clues, that digit’s value is doubled (all other cells’ values are just their digits).
- Rotational Symmetry: The position of all Doublers have a 180° rotational symmetry. (Eg. if there was a Doubler in R3C2, then R7C8 would also contain a Doubler.)
- Arrows: Values along an arrow sum to the value in its attached bulb.

Pretty tricky! It was very satisfying to finally place the last pair of doublers.
