How the BetMGM bonus code offer works for MLB, NBA, and NHL playoff betting

The BetMGM bonus code SIBONUS50 gives new users access to a $1,500 First Bet offer. If your first wager loses, BetMGM returns your stake in bonus bets, up to $1,500. With the NBA playoffs, NHL playoffs, and nearly every MLB team in action on Friday, there is no shortage of markets to target.

Here is how the offer breaks down:

  • New users must use BetMGM promo code SIBONUS50 at registration.
  • A minimum deposit of $10 is required to qualify.
  • If your first bet loses, you receive your stake back in bonus bets, up to $1,500.
  • Wagers over $50 are returned as five bonus bets, each worth 20% of your qualifying stake. For example, a $1,500 losing wager returns five $300 bonus bets.
  • Wagers under $50 are returned as a single bonus bet.
  • Bonus bets expire seven days after issuance.
  • All new users receive $50 in MGM Rewards Points, win or lose.

Say you back the New York Knicks to take a 3-0 series lead over the Philadelphia 76ers and your bet loses. BetMGM returns your stake in bonus bets so you can come back and wager on Game 4. Or if you back the Minnesota Timberwolves to take the series lead over the San Antonio Spurs and win, your payout is yours to keep immediately. The same logic applies to NHL bets on the Buffalo Sabres or Anaheim Ducks, or any MLB game on the board.

Users in Michigan, New Jersey, Pennsylvania, and West Virginia can also opt for the Bet $10, Get $150 offer using the same BetMGM Sportsbook promo code SIBONUS50. Place a $10 wager and if it wins, you receive $150 in bonus bets issued as three $50 bonus bets, in addition to your winnings. The $50 MGM Rewards Points are included here as well, win or lose.

MGM Rewards Points are part of BetMGM's loyalty program and can be redeemed for a range of rewards, including bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the program at the BetMGM Rewards page.
