Main Page

Welcome!

This wiki is primarily intended as a repository of theoretical results regarding Sudoku - both "Classic" puzzles and Variants.

Please feel free to add content, with the following caveats:

• Do not post puzzles directly without the permission of the constructor. Likewise, please give proper credit to the discoverer(s) of a theoretical result, creators of rulesets, etc. - if you don't know who discovered something, use the Template:Citation needed tag!
• This is not intended as a repository for puzzles - there other other places for that (see the Sites link below) - but feel free to add puzzles you feel are noteworthy to your own Setter page.
