X-Wing explanation wanted

Postby RobR » Sat Sep 24, 2005 2:20 pm


I am new to sudoku, and I've been trying to find pattern explanations. I have yet to find an explanation of the X-Wing pattern that is clear, rigorous and minimal. I've found obscure explanations and explanations that have too many restrictions, but I have yet to find a good one. Can somebody point me to one?

Thank you very much!

Welcome, RobR.

Here is one link to a strong site:

SadMan Software Sudoku Techniques

The Simple Sudoku web site is also excellent (but as you mentioned
in another note, it appears to be temporarily not reachable.
Surely that must be temporary.)
