BetMGM Bonus Code SIBONUS50: Claim $1,500 First Bet for NBA & NHL Playoffs, WNBA, and MLB
Use the BetMGM bonus code SIBONUS50 to claim a $1,500 First Bet offer in time for May 23 action across the NHL and NBA playoffs, WNBA, and MLB. New users also earn $50 in MGM Rewards Points win or lose. Find more sportsbook promos to stack your options this weekend.
How the BetMGM bonus code works for NHL and NBA 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 market, including Game 2 of the Eastern Conference Final between the Montreal Canadiens and Carolina Hurricanes or Game 3 of the Cavaliers-Knicks series, and if it loses, BetMGM returns your stake in bonus bets.
Here is how the bonus bet structure breaks down based on your wager size:
- 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 stake.
- Bonus bets expire seven days after issuance.
- BetMGM does not return your stake when you use a bonus bet to place a follow-up wager.
- A minimum deposit of $10 is required to qualify.
Say you bet on Nick Suzuki to record a point in Game 2 and it does not come through. BetMGM credits your account with bonus bets up to $1,500 so you can stay in the action. If your wager wins, you collect your winnings immediately and can withdraw them right away. Either way, you also receive $50 in MGM Rewards Points just for participating.
MGM Rewards Points are part of the BetMGM Rewards program, which lets you redeem points across several categories. Those include bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers for live events. You can learn more about the full rewards program at the BetMGM Rewards page.
Users in Michigan, New Jersey, Pennsylvania, and West Virginia have access to an alternate welcome offer. Use 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 that expire seven days from issuance. You also earn $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.
