BetMGM Bonus Code SIBONUS50 Offers Up to $1,500 for MLB, NBA, NHL and Masters Sunday
New users can claim a generous welcome offer with BetMGM bonus code SIBONUS50 ahead of Sunday's loaded sports slate. The $1,500 First Bet offer provides bonus bets back if your initial wager loses, making it perfect for betting on MLB games, NBA playoff positioning battles, NHL postseason races, or the Masters final round at Augusta National. BetMGM's current sportsbook promos are available through April 12.
How the BetMGM bonus code SIBONUS50 offer works for Sunday's action
The BetMGM bonus code SIBONUS50 unlocks a First Bet offer worth up to $1,500 in bonus bets. New customers must make a minimum $10 deposit and place their first real money wager on any available market. If that initial bet loses, BetMGM returns the entire stake as bonus bets, up to the $1,500 maximum.
The bonus bet structure depends on your wager amount. Bets over $50 receive five separate bonus bets, each worth 20% of the original stake. Smaller wagers under $50 receive one bonus bet equal to the lost amount. All bonus bets expire seven days after issuance and cannot be withdrawn directly.
Key terms and conditions include:
- Minimum $10 deposit required to activate the offer.
- First bet must be placed with real money, not bonus funds.
- Bonus bets expire after seven days from issuance.
- All new users receive $50 in MGM Rewards Points regardless of bet outcome.
- Bonus bet winnings exclude the original stake amount.
For example, if you bet $500 on Scottie Scheffler to win the Masters and he finishes second, you would receive five $100 bonus bets totaling $500. Alternatively, wagering $1,000 on the Lakers to make the playoffs would yield five $200 bonus bets if they fall short.
