Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Anti-Palindrome: On a light red line, the sum of the Nth digit from one end and the Nth digit from the other end must be 10.
Kropki pairs: Black dots separate digits in a 2:1 ratio. White dots separate digits with a difference of 1.
Solution code: Enter column 5 from top to bottom.

nice one :) i dont think i used the intended break-in because i switched to colouring to see the interactions, but nonetheless i liked the ruleset and the puzzle itself!
