How the BetMGM bonus code works for College Football Week 1
The BetMGM bonus code SI1500 unlocks a straightforward welcome offer for new customers. Deposit a minimum of $10 and place your first real money wager on any market you choose, including games from College Football Week 1 Saturday. If your initial 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 your full stake.
- For example, if you wagered $1,500 on Clemson versus LSU 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, which you can use for bonus credits, Marriott Bonvoy Points, merchandise, or Gametime Vouchers.
Whether your first bet wins or loses, you walk away with $50 in MGM Rewards Points. These points are part of BetMGM's loyalty program and can be redeemed across multiple reward categories to enhance your overall betting experience.
