The brief
Normal sudoku rules apply.
Digits in circles must appear at least once in the surrounding 2x2 area.
Digits along a pink line form a set of non-repeating, consecutive digits.
Digits along a blue line have an equal sum N within each box it passes through. Where the line passes through the same box more than once, each individual segment sums to N separately.
