How the BetMGM bonus code works for Tuesday's MLB, NHL and NBA games

The BetMGM bonus code SIBONUS50 delivers exceptional value for new users betting on Tuesday's action-packed schedule. This welcome offer provides up to $1,500 in bonus bets if your first real money wager loses, plus $50 in MGM Rewards Points regardless of the outcome.

• Minimum $10 deposit required to activate the offer.
• First bet protection up to $1,500 in bonus bets if your initial wager loses.
• Bonus bets expire seven days after issuance.

For example, if you bet $500 on the Yankees to beat the Red Sox and they lose, you'll receive your stake back as bonus bets. If you wager on the 76ers to cover against the Celtics and win, you keep your winnings plus the $50 MGM Rewards Points. The NHL playoff games like Canadiens vs. Lightning offer excellent opportunities to use this substantial welcome bonus.

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.
