The Philadelphia Inquirer Sudoku National Championship

The Philadelphia Inquirer Sudoku National Championship, hosted by puzzle master Will Shortz, was an annual sudoku competition run by The Philadelphia Inquirer and held at the Pennsylvania Convention Center in 2007-2009.

Open to a national and international field of contestants from a wide range of ages and backgrounds, the Championship offered three main skill divisions – advanced, intermediate and expert. In addition to the winners of those three categories, prizes were awarded to many more players who compete in a variety of age groups ranging from under-10 years to 80-and-over.

Separate 50 dollar prizes were also given in 27 age categories.

Following the tournament, questions were raised by competitors including 2nd place finisher Thomas Snyder about the performance of Eugene Varshavsky in the tournament. Wearing a hooded sweatshirt during the competition, Varshavsky came nowhere close to his qualifying performance on stage which called into question his abilities as a legitimate sudoku contestant. [6] Following a review of his performance including a retest on similar sudoku puzzles, Varshavsky was disqualified and Chris Narrikkattu, who would have qualified in the same round, was made the third place winner.[7]
