How the BetMGM bonus code offer works for Game 3
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 3, and if it loses, BetMGM returns your entire stake in bonus bets. This is one of the most generous welcome offers available at any major sportsbook right now.
Here is how the bonus bets break down based on your wager amount:
- If you wager $50 or more and lose, you receive five bonus bets, each worth 20% of your qualifying stake. For example, a $1,500 losing bet returns five $300 bonus bets 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- Bonus bets expire seven days after issuance and cannot be withdrawn directly. You must use them before accessing any potential payout.
- Win or lose, you receive $50 in MGM Rewards Points just for placing your first bet.
Say you back the Carolina Hurricanes on the moneyline for Game 3 and the Golden Knights win at T-Mobile Arena. BetMGM will return your stake in bonus bets, giving you another opportunity to get back in the action. If the Hurricanes pull through and Seth Jarvis or Taylor Hall finds the net again, you keep your winnings and still collect those 50 MGM Rewards Points.
Those MGM Rewards Points are worth noting. They can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, or Gametime Vouchers for live events. Learn more at the BetMGM Rewards page.
