How the BetMGM bonus code works for Week 2 NFL
Using the BetMGM bonus code "SI1500" is straightforward. You'll need to make a minimum $10 deposit and place a real money wager on any market you choose, including the Lions-Bills game or any other Week 2 matchup. 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 wagered $1,500 on the Lions-Bills game 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- Bonus bets expire seven days after issuance and cannot be withdrawn as cash.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, which are bonus credits for digital play at BetMGM that can be redeemed for various rewards including MGM Rewards Points, Marriott Bonvoy Points, merchandise, and Gametime Vouchers.
If your first bet wins, you keep your winnings immediately. You can then use any bonus bets on subsequent Week 2 games or other sports throughout the week. The bonus code "SI1500" is required to claim this offer.

Ryan Hagen’s foray into sports betting started early. At just 14 years old, he sought out a lottery kiosk clerk with relaxed gambling mores and convinced the fella to sell him ‘Sport Select’ tickets, which were part of the original government sports betting program in his native Alberta. Now a betting analyst at Sports Illustrated, Ryan prefers to place his bets legally and has established himself as an authority in the sports betting industry. His roles have included lead writer, content editor, managing editor, and more. Ryan has written and edited hundreds of sportsbook reviews and countless news, analysis, and promotional pieces for some of the most prominent companies in the sports betting world. As someone who eats, sleeps, and breathes sports and sports betting, Ryan’s goal is to impart his unbiased betting knowledge to prospective bettors, allowing them to make informed decisions, whether that’s signing up for a sportsbook, mulling over a moneyline, or placing a prop bet. A prolific bettor himself, Ryan lives for the NFL season and believes that every Saturday night from September to February is akin to Christmas Eve. Ryan has a B.A. in Communications from Royal Roads University in Victoria, British Columbia. His work is widely published in the sports betting industry and in publications such as the Calgary Herald and Vancouver Magazine. Off the clock, he can be found traveling, searching for noodles, working on his golf swing, and managing his degenerate number of fantasy football teams.
