How the BetMGM Bonus Code Works for Friday's Games
The BetMGM bonus code SI1500 delivers a straightforward welcome offer for new users. After you register and make a minimum $10 deposit, place your first real money wager on any market from Friday's slate. If your bet loses, BetMGM returns your entire stake as bonus bets, up to $1,500.
Here's how the bonus structure works:
- If you wager more than $50, you receive five bonus bets, each worth 20 percent of your qualifying wager.
- If you wager $50 or less, you receive one bonus bet.
- For example, if you wagered $1,500 on a Friday game and lost, you would receive five $300 bonus bets totaling $1,500.
- Bonus bets expire seven days after issuance.
- You also earn $50 in MGM Rewards Points regardless of whether your first bet wins or loses.
MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers. For more details on how to use your rewards, visit the MGM Rewards program page.
