-Extraordinary Sudoku: With help of Friendly Scrödingers's cells, place digits 0-9 in every row, column, box and marked diagonal.

-Friendly Schrödinger's cells hold two digits; the first being it's box index, the second it's row or column index (or both). Digit 0 corresponds to exacly one index 1-9, which can be determined.

-Negative white kropki: A dot between cells indicates cells with consecutive digits, where 0 is consecutive with 1 and 9. All dots are shown. Consecutive digits may also not coexsist (i.e. Schrödinger's cells may not be composed of consecutive digits).

-Odd/even: digits on squares must be even. Digits on circles must be odd.
