Sudopedia:About

Sudopedia is a free online encyclopedia dedicated to the game of Sudoku.

Readers

If you are new to the game of Sudoku, you may want to read the introduction.

If you already know what Sudoku is, but don't know where to start, the main entry points are the indexes of terminology and solving techniques. Not every term is listed separately. The search facility can point you in the right direction.

Writers
