A while ago i came across a Wired article about a type of puzzle that was sweeping across England. It's called a SuDoku and it involves placing numbers on a grid such that no number is repeated in any row, column, or "sector." I found these challenges quite interesting and started playing around with them. If you search at Amazon.co.uk you'll find a bunch of different books containing the puzzles but apparently they still haven't been published on this side of the pond. I did find a site called the Daily Sudoku where you can print out a new one each day if you would like to give it a try.
