William T. Walters (born July 15, 1946) is an American entrepreneur, philanthropist, New York Times best-selling author, and one of the most successful American sports bettors of all time, having a winning streak which extended over 30 years.

Betting is an optional way to enjoy a five-player game in which one player rotates out each hand. The fifth player looks at each player's hand after the Charleston is complete and makes a note of the name of the player whom she thinks will win the hand (or if she thinks it will be a wall game).
