Rules

Standard Sudoku: Place the digits 1–9 into the grid so that every row, column, and 3x3 box contains each digit exactly once.

Mummified Cells: A cell is mummified if and only if all of its orthogonally adjacent neighbors contain odd digits. There is exactly one mummified cell in every row, column, and 3x3 box. Each of the 9 mummified cells contains a different digit. A mummified cell has a value of 0. All other cells have a value equal to the digit they contain.

Nabner Lines: The yellow lines are Nabner lines. No two values on a single Nabner line may be consecutive. Furthermore, every Nabner line is unique; no two lines may contain the same set of values.

Black Kropki Dots: If a Kropki dot lies between two cells, their values have ratio 1:2. (One is double the other)
