Sudoku

In summary: I'm not sure, I haven't really put much thought into it.In summary, the game Sudoku was designed about 300 years ago and is likely inspired by the Latin square invention of Leonhard Euler. There is no mathematical way to solve Sudoku, but computer programs can use a brute force method to find solutions. The 9x9 Sudoku problem is O(1) and takes 5-20 minutes to solve advanced puzzles. There is an algorithmic method to solving Sudoku and it is possible to have unsolvable puzzles. The difficulty of a Sudoku is subjective and does not necessarily depend on the number of starting entries.

FYI: June 2006 issue of Scientific American has an article titled "The science behind suduko". Just putting it out there.
