BetMGM Bonus Code SIBONUS50 Offers Up to $1,500 for MLB, NHL and NBA Playoff Betting

New users can claim a valuable welcome offer with the BetMGM bonus code SIBONUS50 for Monday's packed sports slate. The promotion provides up to $1,500 back in bonus bets if your first wager loses on MLB, NHL or NBA playoff action. BetMGM also offers excellent sportsbook promos as of Apr. 13.
How the BetMGM bonus code works for tonight's NHL and MLB action
The BetMGM bonus code SIBONUS50 delivers substantial value for new users betting on tonight's busy sports schedule. After registering and making your first deposit of at least $10, place your initial wager on any market. If that bet loses, BetMGM returns your stake up to $1,500 in bonus bets, plus you receive $50 in MGM Rewards Points regardless of the outcome.
The bonus bet structure depends on your wager amount. Stakes over $50 are divided into five equal bonus bets worth 20% each of your original wager. For example, if you bet $1,000 on the Rangers-Panthers NHL matchup and lose, you would receive five $200 bonus bets totaling $1,000. Smaller wagers under $50 receive one bonus bet equal to the stake amount.
Key terms include:
• Bonus bets expire seven days after issuance.
• Minimum $10 deposit required to qualify.
• Available to new users only.
• MGM Rewards Points include bonus credits for digital play, Marriott Bonvoy Points, and merchandise.
Consider wagering on tonight's high-stakes NHL games where playoff positioning remains fluid. Teams like the Hurricanes, Rangers and Maple Leafs are playing with playoff-level intensity, creating excellent betting opportunities. If your Rangers moneyline bet wins against Florida, you keep your winnings and still earn the MGM Rewards Points. If it loses, you get your full stake back in bonus bets to use on upcoming games.
