BetMGM Bonus Code SIBONUS50: Bet $1,500 on Hurricanes vs. Golden Knights Game 4

Use the BetMGM bonus code SIBONUS50 to claim a $1,500 First Bet offer, available as of Tuesday, June 9. New users can also find this and other sportsbook promos to bet on Hurricanes vs. Golden Knights Game 4. A code is required, and that code is SIBONUS50.
How the BetMGM bonus code offer works for Game 4 of the Stanley Cup Final
The BetMGM bonus code SIBONUS50 unlocks a First Bet offer worth up to $1,500 for new users. Place your first real money wager on any market, including Hurricanes vs. Golden Knights Game 4, and if it loses, BetMGM will return your stake in bonus bets. You must make a minimum deposit of $10 to qualify.
Say you bet $1,500 on the Carolina Hurricanes to win Game 4 and keep their Stanley Cup Final hopes alive. If that bet loses, BetMGM will issue five bonus bets, each worth $300, totaling $1,500. If you wager less than $50 and lose, you receive one bonus bet equal to your stake. Bonus bets expire seven days after issuance.
If your first bet wins, you collect your winnings immediately and can withdraw them right away. Keep in mind that bonus bets cannot be withdrawn directly. You must place them first, and BetMGM does not return your stake when using bonus bets.
Here is a quick breakdown of the key terms and conditions:
- New users only; minimum $10 deposit required.
- If your first bet loses, you receive your stake back in bonus bets, up to $1,500.
- Wagers above $50 are returned as five bonus bets, each worth 20% of your qualifying wager.
- Wagers under $50 are returned as one bonus bet equal to your stake.
- Bonus bets expire seven days after issuance.
- Win or lose, you receive $50 in MGM Rewards Points.
Those MGM Rewards Points are part of BetMGM's loyalty program and can be redeemed in several ways, including bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the program at the BetMGM Rewards page.
Users in Michigan, New Jersey, Pennsylvania, and West Virginia also have access to an alternate welcome offer. Use the BetMGM Sportsbook promo code SIBONUS50 to place a $10 first bet, and if it wins, you receive $150 in bonus bets in addition to your winnings.
