This puzzle was my test of how a sudoku would work that features only zipper lines (no other constraints or given digits). It was fun to make and should be a fairly easy one to solve :)

Normal sudoku rules apply: place the digits 1-9 in each row, column and 3x3 box.

Every coloured line is a zipper line. Pairs of cells an equal distance from the centre of a zipper sum to the digit in the central cell of that zipper.
