How the BetMGM bonus code works for Week 1 college football
The BetMGM bonus code "SI1500" unlocks a welcome offer that gives you bonus bets if your first wager doesn't land. Here's what you need to know about claiming this promotion:
- You must make a minimum $10 deposit to qualify for the offer.
- Place your first real money bet on any college football game during Week 1, including Clemson at LSU, Boise State at Oregon, or any other matchup on the slate.
- If your first bet loses, you'll receive your entire stake back as bonus bets, up to $1,500.
- Bonus bets are issued as five separate $300 credits if you wagered more than $50, or as one bonus bet if you wagered less than $50.
- All bonus bets expire seven days after issuance, so use them quickly on additional Week 1 games.
- You'll also earn $50 in MGM Rewards Points, regardless of whether your first bet wins or loses.
For example, if you place a $1,500 first bet on Clemson versus LSU and it doesn't win, you'll receive five $300 bonus bets to use on other college football games throughout the opening weekend. If you place a $30 first bet and it loses, you'll get one $30 bonus bet instead.
MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. Learn more about the program at the MGM Rewards page.
