How the BetMGM bonus code works for Week 1 college football

The BetMGM bonus code SI1500 unlocks a straightforward welcome offer for first-time bettors. You'll need to make a minimum $10 deposit and place your first real money wager on any Week 1 college football game. 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 $50 or less and lose, you receive one bonus bet equal to your stake.
If you wager more than $50 and lose, you receive five bonus bets, each worth 20 percent of your qualifying wager.
For example, if you wagered $1,500 on LSU versus Clemson and lost, you would receive five $300 bonus bets.
Bonus bets expire seven days after issuance and cannot be withdrawn as cash.
You also earn $50 in MGM Rewards Points regardless of whether you win or lose your first bet.

MGM Rewards Points provide multiple redemption options, including bonus credits for digital play at BetMGM, MGM Rewards Points toward hotel stays, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the full rewards program at the MGM Rewards page.

The bonus code SI1500 is required to claim this offer. You must use it during registration to qualify. Whether your first bet on a Week 1 game wins or loses, the bonus bets arrive in your account immediately if you lose, allowing you to continue betting throughout the weekend.
