How the BetMGM bonus code works for 49ers vs. Chargers
The BetMGM bonus code SI1500 unlocks a welcome offer that returns your first wager in bonus bets if it loses. You'll need to make a minimum $10 deposit and place a real money bet on any market, including the 49ers vs. Chargers game. If your first bet loses, BetMGM returns your entire stake, up to $1,500, in bonus bets.
Here's how the bonus bets are distributed. If you wager more than $50, you receive five bonus bets, each worth 20 percent of your qualifying wager. For example, if you bet $1,500 on the 49ers vs. Chargers and lose, you'd get five $300 bonus bets. If you wager less than $50, you receive one bonus bet equal to your stake. All bonus bets expire seven days after issuance, so plan your additional wagers accordingly.
The offer also includes $50 in MGM Rewards Points, which you earn whether you win or lose your first bet. MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers. You can learn more about the full rewards program at the BetMGM Rewards page.
