Rules
Normal sudoku rules apply.
Box borders divide each blue line into segments with the same sum.
Along orange lines, adjacent digits differ by at least 4.
Digits separated by a V sum to 5. ALL V's are given.
Exactly one of the digits from 1-9 is subject to the anti-bishop rule, meaning that it cannot see the same digit diagonally.
Solution code: Column 1

Lovely puzzle! I always love the negative V or XV constaint. And the anti-bishop was a very nice touch! Great fun, thanks for sharing

I'm sure there was a more elegant way to find the bishop digit aside from "get pretty stuck and decide to go through each number to see if it's feasible."
But hey, if it works it works.

ND: No, you just have to whittle down the options along the way until there is a winner. Thnks for solving!

Nice puzzle.
One of the digits is subject to anti-bishop rule. Hmmm.. I wonder, which one?
