Free printable sudoku brings you this YouTube video.
It is a nail-biting video from the 2009 National Sudoku Championship in Philadelphia. US and World Sudoku Champion Thomas Snyder goes for the $10,000 1st prize but writes too fast in the closing seconds and makes a mistake. Three minutes later, Tammy McLeod turns in a correct grid to win the tournament and a spot on the US Sudoku Team.
Also of note is 3rd place getter Eugene Varshavsky, seen here in his hooded sweatshirt motionless in front of his grid. He was allegedly suspected of cheating earlier on in the tournament, particularly after he could only place three digits after 8 minutes in the finals.
