How the BetMGM bonus code works for Wednesday's games
The BetMGM bonus code "SI1500" unlocks a welcome offer that returns your entire first wager in bonus bets if it loses, up to $1,500. Here's how it breaks down:
- You must make a minimum $10 deposit to qualify for the offer.
- Place your first real money bet on any market, including college football games like North Carolina vs. TCU, San Jose State vs. USC, or NC State vs. Virginia, MLB matchups such as Astros vs. Yankees or Dodgers vs. Braves, or the WNBA game between Valkyries and Sun.
- If your bet loses, BetMGM returns your stake 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.
- You'll also receive $50 in MGM Rewards Points regardless of whether you win or lose your first bet.
MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, additional 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.
For example, if you place a $1,500 bet on the Dodgers vs. Braves game and it loses, you'll receive five $300 bonus bets to use on future wagers. If you place a $40 bet on North Carolina vs. TCU and it loses, you'll get one $40 bonus bet. Bonus bets cannot be withdrawn as cash and must be used on additional wagers before you can cash out any winnings.
