Fans can watch the matches live or can join one of the celebrity’s teams. Any game that is won during that time goes to the celebrity’s total. For the less word-savvy philanthropists, donations can be made directly to one of the celebrity’s charities through CrowdRise.com, a fundraising site created by Norton.

Probably one of the most famous celebrity Words enthusiast, Alec Baldwin, who was famously kicked off a plane for playing the game, is not part of the tournament. "Next year, for sure, if I have any say in it," Norton told the Associated Press (va CBS News). "I'm going to win this year, so adding him to the mix next year will make it interesting for me."

The Bourne Legacy actor graduated from Yale University with a history degree.
