BetMGM Bonus Code SIBONUS50: Bet $1,500 on Knicks vs. Spurs NBA Finals Game 1
Use the BetMGM bonus code SIBONUS50 to claim a $1,500 First Bet offer ahead of Knicks vs. Spurs NBA Finals Game 1. New users also earn $50 MGM Rewards Points win or lose. Check out all available sportsbook promos before placing your first bet this Wednesday, June 4.
How the BetMGM bonus code works for NBA Finals Game 1
The BetMGM bonus code SIBONUS50 unlocks a First Bet offer worth up to $1,500 for new users. Enter the code at registration, make a minimum $10 deposit, and place your first real-money wager on any market, including Knicks vs. Spurs Game 1. If your bet wins, you keep the winnings. If it loses, BetMGM returns your stake in bonus bets.
Here is how the bonus bet structure breaks down based on your wager amount:
- Wagers of $50 or more are returned as five bonus bets, each worth 20% of your original stake.
- Wagers under $50 are returned as a single bonus bet equal to your stake.
- Bonus bets expire seven days after issuance and cannot be withdrawn directly.
- You must use each bonus bet before accessing any potential payout from it.
For example, if you place a $1,500 wager on the Spurs to win Game 1 and it loses, BetMGM will credit your account with five $300 bonus bets totaling $1,500. Alternatively, if you bet $100 on Jalen Brunson to lead the Knicks in scoring and it wins, you keep all the winnings with no strings attached. Either way, every new user receives $50 in MGM Rewards Points regardless of the outcome.
Users in Michigan, New Jersey, Pennsylvania, and West Virginia have access to an additional welcome offer. Use bonus code for BetMGM SIBONUS50 to place a $10 first bet, and if it wins, you receive $150 in bonus bets issued as three $50 credits. That offer also includes $50 in MGM Rewards Points win or lose.
MGM Rewards Points are part of the BetMGM Rewards program, which lets you redeem points across a range of options, including bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers for live events.
