How the BetMGM bonus code works for the NLDS
The BetMGM bonus code SI1500 unlocks a welcome offer that returns your entire first wager in bonus bets if it loses, up to $1,500. You must make a minimum $10 deposit and place a real money bet on any market, including the Dodgers vs Braves or Brewers vs Padres games. Here's how the bonus structure works:
- If you wager more than $50, you receive five bonus bets, each worth 20% of your qualifying wager.
- If you wager $50 or less, you receive one bonus bet.
- For example, if you wagered $1,500 on the Dodgers vs Braves and lost, you would receive five $300 bonus bets.
- Bonus bets expire seven days after issuance.
- You also earn $50 in MGM Rewards Points regardless of whether you win or lose.
MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers. Learn more about the program at the MGM Rewards page.
If your first bet on the Brewers vs Padres wins, you keep your winnings and can withdraw them immediately. If it loses, BetMGM credits your account with bonus bets within 24 hours.
