BetMGM Bonus Code SIBONUS50: Claim $1,500 First Bet for MLB, NBA and NHL Playoffs
Use the BetMGM bonus code SIBONUS50 to claim a $1,500 First Bet offer in time for Wednesday's packed sports slate. From Dodgers-Astros to NBA and NHL second-round playoff action, there is no shortage of games to target with your first wager. Check out more sportsbook promos before locking in your pick this May 6.
How the BetMGM bonus code offer works for MLB, NBA and NHL playoff betting
The BetMGM bonus code SIBONUS50 unlocks a First Bet offer worth up to $1,500 for new users. Place your first real money wager on any available market, and if it loses, BetMGM will return your stake in bonus bets. You also receive $50 in MGM Rewards Points regardless of whether your bet wins or loses.
Here is how the bonus bet structure breaks down based on your wager amount:
- If you wager $50 or more and lose, you receive five bonus bets, each worth 20% of your original stake. For example, a $1,500 losing wager returns five $300 bonus bets totaling $1,500.
- If you wager less than $50 and lose, you receive one bonus bet equal to your full stake.
- Bonus bets expire seven days after issuance and cannot be withdrawn directly — you must use them on a wager first.
- A minimum deposit of $10 is required to qualify.
Say you back the Dodgers on the moneyline against Houston and the bet loses. BetMGM returns your stake in bonus bets, giving you another shot at Wednesday's NBA or NHL playoff action. If your Dodgers wager wins, you collect your payout immediately and still pocket $50 in MGM Rewards Points.
MGM Rewards Points are part of BetMGM's loyalty program and can be redeemed in several ways, 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.
New 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, plus $50 in MGM Rewards Points win or lose.
This BetMGM promotion is available to first-time users in the following states: AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MS, NC, NJ, OH, PA, TN, VA, WV, WY. It is not available in NV, NY, or Ontario, Canada.
