Sudoku: Within the main grid (inside the thick border), fill every cell with a digit from 1-5 such that digits do not repeat in a row or column.
Zippers: Pairs of values equidistant from the centre of a lavender Zipper line have the same sum. Where the centre lies in a cell, the sum is the value in that cell. The sum may be different for different lines.
Full Rank: A value in an external cell represents the rank of the number formed by reading the digits in that row or column from that direction, where (1) is the lowest such row or column and (20) is the highest..
N.B. If two ranks are tied, the value in both external cells is the lower of the two ranks being shared. For example, if the lowest four ranks are "12453", "13524", "13524" and "15432", the values in the relevant external cells would be (1), (2), (2) and (4) respectively.

Difficulty reduced as what I thought was the hardest step is not actually required!
