- Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each. - Black Kropkis: Digits in cells separated by a black dot have a 1:2 ratio. - Odd/Even: Digits in gray circles are odd. Digits in gray squares are even. - X: Cells separated by X must sum to 10. - V: NEGATIVE CONSTRAINT: No two orthogonal cells can sum to 5. - Antiking: Cells which are a (chess) king's move apart cannot share the same digit. - Disjoint Sets: Any identical local position across the nine distinct boxes forms an extra virtual group of 9 cells that also must contain the digits 1 through 9 uniquely. - Maximum Cells: Gray boxes marked with outward-pointing indicators show that the center value is strictly greater than the four adjacent horizontal and vertical neighbors.
