Top March Madness bracket contests

*Not open to Ontario residents.

DraftKings Zero Right Bracket Challenge

Self-sabotage for a shot at $100,000

Anyone can focus on picking a winning bracket – but it's just as difficult to be the person in your pool with the worst result.

DraftKings is ready to reward the worst of the worst with a $100,000 grand prize for the player who offers up the worst March Madness bracket of all.

Every time you correctly predict a winning matchup, you gain a point – and that's bad, since the grand prize will be awarded to the participant with the fewest total points.

BetRivers Squares

It's for sharps, as well!

BetRivers isn't offering a traditional March Madness bracket contest, but you'll want to check out what they're offering nonetheless.

Following up on the popularity of its Super Bowl Squares contest, BetRivers is offering bettors the opportunity to choose a square whenever they make a wager of $20 or more on a select outcome. Correctly choose the square that corresponds to the final score of a specific game, and a bettor can win up to $10,000.
