Normal sudoku rules apply.

Box 5 is a magic square. This means that every row, column and the main diagonals all add up to the same number.

Digits an equal distance from the center of a lavender 'Zipper Line' must sum to the digit in the middle of that line. You cannot use the same sum to make the total on the same line (e.g. 8 = 4+4 can only be used once on the same line).

The arrows at the side of the grid are little killer clues which indicate the sum of the digits along the arrow.
