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.
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 highest four ranks are "52431", "53124", "53124" and "54213", the values in the relevant external cells would be (17), (18), (18) and (20) respectively.
Kropki knights: all cells (including external cells) that are a knight's move away from the knight differ by 1 from the value in the knight's cell.
(Solution checker: don't mark external digits)

I thought I was completely stuck, then re-read the rules and it all dropped out! Very neat.
