Overview of Yahoo Bracket Mayhem

Take the court with Yahoo Bracket Mayhem and try your luck at picking the winners of each game in this year's NCAA men's or NCAA women's college basketball tournament bracket. Once you’ve signed up, create up to 10 brackets and enter each one in a max of 15 groups. Get started in early February and sign up by signing into the Bracket Mayhem homepage.

Fill out your brackets

Once the teams are selected for the men's and women's NCAA tournaments in March, you'll be able to fill in your bracket. Click your bracket name from either the men's or women's Bracket Mayhem homepage to make your picks. It's important to pick every game or else your bracket won't be saved.

Put your bracket up against friends

Create or join groups to play with family, co-workers, or strangers. Each group has its own leaderboard, so you'll always be able to know who's on top in the standings. Private group commissioners can customize their group's settings, scoring or privacy options, and invite new members.

See where you rank in the competition on the Leaderboards

Scores and standings are updated as games finish and are reflected no later than the morning after a game is played. Access them from the Bracket Mayhem homepage by mousing over Leaderboards.
