Doubler cells are fun, half-baked cells are fun, so why not both. With a little star battle thrown in for good measure.

Extra special thanks to mathpesto for his diligent testing and feedback on multiple drafts.


Rules:

Normal Sudoku Rules apply.

In the grid are 9 "doubler" cells and 9 "half-baked" cells, and every row, column and box has exactly one of each type of cell. A cell cannot be both a "doubler" and "half-baked", and none of the 18 "doubler" and "half-baked" cells can touch any other orthogonally or diagonally (like star-battle). Doubled/halved digits do not need to be unique, the same digit can appear in multiple "doubler" and/or multiple "half-baked" cells.

For the purposes of other clues, the value of a "doubler" cell is double the digit in the cell and the value of a "half-baked" cell is half of the digit in the cell.

The values of two cells separated by a V sum to 5. The values of two two cells separated by an X sum to 10. The values of two cells separated by an XV sum to 15. Not all V's, X's and XV's are given.

Cells with a grey square have an even value. The cell with a grey diamond (r5c1) does NOT have an even value.

Small correction with the solution code, I think it should say "left to right, top to bottom"

Thank you for the puzzle, it was a joy to solve!
