The US National Sudoku Championship has come and gone, but there is still opportunity for competitive Sudoku.

The Sudokucup is an online Sudoku Tournament that will be held on January 16th, 2010. Thomas Snyder will be authoring the puzzles. Practice puzzles will be available in January, but signups are already open and anyone can enter.
