BetMGM Bonus Code SIBONUS50: Claim Up to $1,500 for NBA Playoffs, NHL Playoffs and MLB Games

New users can claim the BetMGM bonus code SIBONUS50 for Thursday's action-packed sports slate featuring NBA playoffs, NHL playoffs and MLB games. This welcome offer provides up to $1,500 back in bonus bets if your first wager loses, plus $50 in MGM Rewards Points regardless of the outcome. Thursday's games include Yankees vs. Red Sox, Knicks vs. Hawks, and Bruins vs. Sabres among other exciting matchups. BetMGM's current sportsbook promos are available through April 23.
How the BetMGM bonus code offer works for Thursday's games
The BetMGM bonus code SIBONUS50 provides new users with protection on their first wager up to $1,500. After registering and making a minimum $10 deposit, you can place your first bet on any of Thursday's games including the NBA playoff matchups or MLB contests like Dodgers vs. Giants. If your initial wager wins, you keep your winnings and still receive $50 in MGM Rewards Points. However, if your first bet loses, BetMGM returns your stake as bonus bets up to the $1,500 maximum.
For example, if you bet $500 on the Knicks to cover the spread against the Hawks and lose, you'll receive five bonus bets worth $100 each. If you wager less than $50, you receive one bonus bet equal to your stake. The bonus bets expire after seven days and must be used before you can withdraw any potential winnings.
Key terms include:
• Minimum $10 deposit required.
• First bet protection up to $1,500 in bonus bets.
• Bonus bets expire after seven days.
• $50 MGM Rewards Points awarded win or lose.
• Code SIBONUS50 required at registration.
MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. Additional information about the rewards program is available at https://www.nj.betmgm.com/en/p/betmgmrewards.
