Normal sudoku rules apply. Place the digits 1-6 once each in every row, column, and 2x3 box.
Killer: digits inside a caged region must not repeat and sum to the total shown in the corner.
Cells connected by an X sum to 10. Cells connected by a V sum to 5. Not all Xs and Vs are given.
Anti-king rules apply: cells touching diagonally cannot contain the same digit.
Solve in VariantDoku (iOS, macOS, Android) or on SudokuPad.
Solution code: Enter the digits of row 1.

I love negative constraints, and anti-king is particularly powerful in a 6x6. Very nice, thanks.

Love that the puzzles feel like they're evolving everyday, from normal variant to irregular to global constraints. Thanks :)
