How the BetMGM bonus code works for Monday's games
The BetMGM bonus code "SI1500" unlocks a straightforward welcome offer for new users. You'll need to make a minimum $10 deposit and place a real money wager on any game from Monday's slate. If your first 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 bet $1,500 on a Red Sox-Blue Jays game and lose, you'd receive five $300 bonus bets.
- Bonus bets expire seven days after issuance.
- You'll also earn $50 in MGM Rewards Points regardless of whether you win or lose.
MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers. Learn more about the program at the MGM Rewards page.
When you place your first bet on Monday's games, whether it's the Red Sox-Blue Jays matchup, a Mets-Braves game, or any other contest on the board, you're protected if the wager doesn't land. The bonus bets you receive can then be used on any subsequent games throughout the week.
This BetMGM promotion is available to first-time users in the following states: AZ, CO, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MS, NC, NJ, OH, PA, TN, VA, WV, WY. It is not available in NV, NY, or Ontario, Canada.
How to claim the BetMGM bonus code SI1500 for Monday's slate
