Standard arrow, XV and white dots, but some fairly complex interactions. Consensus testing opinion was 4 stars. Good luck!

• Normal sudoku rules apply: Place the digits 1 to 9 once each in every row, column, and 3x3 box
• Arrows: Digits on an arrow sum to the digit in the attached circle
• XV: Digits separated by an X sum to 10. Digits separated by a V sum to 5
• Kropki: Digits separated by a white dot are consecutive
• No negative constraint, i.e. Not all dots or XV are necessarily given
