BetMGM Bonus Code SIBONUS50 Delivers Up to $1,500 for MLB, NBA, NHL and Masters Action
New users can claim a massive welcome offer with BetMGM bonus code SIBONUS50 for Thursday's loaded sports slate. The promotion delivers up to $1,500 in bonus bets if your first wager loses, plus $50 in MGM Rewards Points regardless of outcome. With MLB continuing its early-season momentum, NBA playoff positioning heating up, NHL division races intensifying, and Masters opening-round action at Augusta National, Apr. 9 offers exceptional betting opportunities across multiple sports with this generous sportsbook promos offer.
How the BetMGM bonus code works for Thursday's sports action
The BetMGM bonus code SIBONUS50 provides new customers with substantial protection on their initial wager. After registering and making a minimum $10 deposit, you can place your first bet on any market, including Thursday's MLB games, NBA matchups, NHL contests, or Masters opening-round action. If your wager wins, you keep your winnings and still receive $50 in MGM Rewards Points.
However, if your first bet loses, BetMGM returns your stake up to $1,500 in bonus bets. For wagers over $50, you receive five bonus bets worth 20% of your qualifying wager each. For example, if you bet $1,000 on Scottie Scheffler to win the Masters and it loses, you would receive five $200 bonus bets totaling $1,000. Wagers under $50 receive one bonus bet equal to your stake amount.
Key terms and conditions include:
- Bonus bets expire seven days after issuance.
- Minimum $10 deposit required to qualify.
- Available for first-time BetMGM customers only.
- $50 MGM Rewards Points awarded win or lose.
