Have you recovered yet from the madness that is Days 1 and 2 of the NCAA Tournament? Don’t worry, us neither. If you missed out on betting these wild days of college basketball, don’t fret — US sportsbooks continue offering their best March Madness promos into the Round of 32. Just because Round 1 busted your bracket doesn’t mean it also has to bust your involvement in tournament action. Let’s explore what promos are still available this weekend.

Keep up with TheLines for complete coverage of college basketball odds from the First Four to the Final Four. And watch for college hoops expert Eli Hershkovich to drop his best bets for the Round of 32, Sweet 16, and beyond.

BetMGM March Madness Bonus Code THELINES: Get Up To $1,500

BetMGM offers the best sign-up offer for new bettors, as determined by our team of experts at TheLines. It provides a refund of up to $1,500 in bonus bets if your first bet loses. In March Madness, there’s no better feeling than a second chance after being on the wrong side of a historic upset. Burned this year by laying the points with Clemson, just for them to score 13 first-half points? Fear no more — BetMGM provides bonus bets if your first wager faces the same upset.

Use the bonus code THELINES and opt in to this promo before making your initial deposit. Be sure to use those bonus bets within seven days of receiving them or they’ll expire!

Bet365 March Madness Bonus Code THELINES: Bettor’s Choice!

Bet365 Sportsbook offers new users the choice between one of two promos:

  • Bet $5, get $150 in bonus bets
  • First-bet safety net up to $1,000

These two promos work differently for different levels of bettors. Recreational bettors looking to bet $50 or less per play will see more value in the bet $5, get $150 promo. High-rolling bettors may see more value in having larger bets backed by the safety-net promo. The latter provides a refund in bonus bets if your first wager at bet365 loses, up to $1,000.

Use the bonus code THELINES to qualify for either promo and select carefully!
