Your daily Sudoku game

The game of Sudoku has experienced tremendous popularity in recent years, particulary last year (2006). The history of the game only dates back to 1979, which this article from Wikipedia demonstrates:

The modern puzzle Sudoku was invented in Indianapolis in 1979 by Howard Garns. Garns' puzzles appeared in Dell Magazines, which published them under the title "Number Place". Sudoku became popular in Japan in 1986, when puzzle publisher Nikoli discovered the game in older Dell publications. The puzzles became an international hit in 2005.
