Here's a thought for the day: why do they publish answers to Sudoku puzzles?
Think about it - you either get them out or you don't. What possible use is it to be able to say 'oh, there's a 3 in that square'? Nothing about the provided solution helps you understand why there's a 3 there, or how to see that there should be a 3 there. It's just a 3.
Sudoku answers: file under 'inexplicable'.
A quick glimpse of the answer can turn a sudoku from a very hard level to an easy. I pity the person who checks every line.
