Best Promotions for 2021 March Madness

BetMGM – $2,000,000 for the perfect bracket – $100k guaranteed

By far the biggest offer of any sportsbook operator offering bets on the NCAA March Madness comes from BetMGM. Create a perfect bracket, and you win the $2 million grand prize!

Now, we know that it is difficult to get all the games right, so BetMGM has put in a $100,000 guaranteed extra prize for the best bracket, meaning the one who picks the most winners correctly over the entire tournament.

How to enter the BetMGM $2 million Bracket Challenge for free

All you need is an active and verified sports betting account at BetMGM. Log in to your account and sign in to the challenge. Create your bracket and send it in, and that’s it. You don’t even have to wager any money, because entering the 2 Million Dollar Bracket Challenge is completely free!

You must hand in your bracket before the end of the promotion period, which is on 11:59 AM ET on March 19, so hurry up!

The $2 million grand prize payout

You need to complete your full bracket before the start of first game on March 19, 2021. If you get every winner correct all the way to the National Championship final, you win the grand prize of $2 million. Should there be more than one perfect bracket, BetMGM will divide the prize money evenly.

Note: the First Four games do not count for the bracket prediction.

$100,000 guaranteed payout

If nobody manages to predict a perfect bracket, the player with the most correct predictions wins $100,000 guaranteed! Again, if there’s a tie, the winners will split the money. You get one point for every correct prediction. Collect more than anybody else, and the prize is yours.

The First Four games are excluded from this promotion. Your predictions start with Round 1.

Sports bettors can get $160 in Free Bets when they bet $10 on a college basketball match up during the month of March.

During the First Round (March 19-20), when you bet $10 on any college basketball game, you will receive a $10 Free Bet for each game played that day ($160 in free bets).

And for the Second Round (March 21-21), if you bet $20 on one of the games played that day, you will get a $20 Free Bet for each game played ($160 in free bets).

If playing parlays is your thing, you will be happy to hear about the Parlay Boost promo at BetMGM.

Players get a Parlay Boost Token every day of action during March Madness. Then, when betting a parlay with 3 legs or more, you can apply one of those tokens to your wager. If you win your parlay, BetMGM will give you an extra 10% on your payout.
