With all humility, I think this is the best puzzle I have created. Please enjoy and give any feedback you have! Thanks for playing!

• 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.
