This puzzle uses features Solve Paths doesn't support yet: diagonals. The board may not match the original rules.
The normal Sudoku rules apply: in each row, each column, and each bold-outlined 3x3 box, the digits 1–9 must each appear exactly once. Enter the numbers 1 through 9 on each of the two diagonals. Additionally: Green spectral lines: Adjacent digits along any green spectral line differ by at least 5. Yellow atoms: Around an atom, all surrounding digits are either all even or all odd. Electrons: Cells connected by a white electron contain consecutive digits. Cells connected by a black electron have a 1:2 ratio. Not all white and black electrons are given.
