Normal sudoku rules apply.

Box borders divide blue region sum lines into segments with the same sum and each line must contain exactly one repeat digit.

Once a digit has appeared on a blue line as a 'repeat digit,' it may not do so again.

Antiknight: Digits cannot be a knight's move (in chess) away from themselves.

Digits in cages must not repeat and sum to the total in the top left corner.

Digits on the green line must not repeat and differ by at least five.
