BetMGM Bonus Code SIBONUS50: Claim $1,500 First Bet for NBA and NHL Playoffs, MLB Games
Use the BetMGM bonus code SIBONUS50 to unlock a $1,500 First Bet offer, one of the best sportsbook promos available heading into Friday, May 1. With pivotal Game 6 matchups across the NBA and NHL playoffs, plus a full MLB slate, there is no shortage of action to target. A code is required — enter SIBONUS50 at registration.
How the BetMGM bonus code offer works for NBA and NHL playoff games
New users who apply the BetMGM bonus code SIBONUS50 at sign-up can place a first bet of up to $1,500 on any available market, including Friday's high-stakes Game 6 playoff matchups. If that first wager loses, BetMGM returns the full stake in bonus bets. If it wins, you keep the winnings outright.
Here is how the bonus bet structure breaks down depending on your wager size:
- Wagers of $50 or more are returned as five bonus bets, each worth 20% of your original stake. For example, a $1,500 losing bet would yield five $300 bonus bets.
- Wagers under $50 are returned as a single bonus bet equal to your stake.
- Bonus bets expire seven days after issuance.
- BetMGM does not return your stake when using bonus bets to place subsequent wagers.
- A minimum deposit of $10 is required to qualify.
Say you bet $200 on a Game 6 NBA playoff favorite and the wager loses. BetMGM would issue five $40 bonus bets, giving you plenty of flexibility to spread action across the rest of the playoff schedule or the MLB slate. Win or lose on your first bet, you also receive $50 in MGM Rewards Points automatically.
MGM Rewards Points are part of BetMGM's broader 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.
Users in Michigan, New Jersey, Pennsylvania, and West Virginia also have access to an alternate welcome offer. Use the BetMGM Sportsbook promo code SIBONUS50 to place a $10 first bet, and if it wins, you receive $150 in bonus bets in addition to your winnings. Those bonus bets are issued as three $50 credits, each valid for seven days.
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.
