How the BetMGM bonus code works for College Football Week 5
The BetMGM bonus code SI1500 unlocks a substantial welcome bonus for first-time users. After you register and make a minimum $10 deposit, place your first real money wager on any College Football Week 5 game. 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 $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 Pittsburgh versus Virginia Tech and lost, you would receive five $300 bonus bets.
- Bonus bets expire seven days after issuance and cannot be withdrawn as cash.
- You earn $50 in MGM Rewards Points whether your first bet wins or loses.
MGM Rewards Points are bonus credits you can use for digital play at BetMGM, or you can convert them into Marriott Bonvoy Points, merchandise, or Gametime Vouchers. Learn more about the BetMGM Rewards program.
