This was my entry for Scojo's impostor sudoku challenge, and I was assigned to imitate Chris Napolitano. Those who know his work will see exactly which puzzle I ended up using for inspiration.

Rules:

- Standard sudoku rules apply.

- Lockout - digits along a lockout line must not be between the two end digits in the diamonds, which must differ from each other by at least 4.

- Kropki - Black Kropki dots separate digits in a 2:1 ratio. No negative constraint.

- XV pairs- Xs separate digits that sum to 10, Vs separate digits that sum to 5. No negative constraint.

- Palindromes - the string of digits on a light gray palindrome line must read the same backwards and forwards.

Region Sum Lines - Light blue lines are Region Sum lines where the border of a 3 by 3 box splits the line into parts with equal digit sums.
