How the BetMGM bonus code works for Bills vs. Rams
The BetMGM bonus code "SI1550" unlocks a welcome offer designed for first-time bettors. Here's how it functions: you'll need to deposit at least $10 and place a real money wager on any market, including the Bills vs. Rams matchup. If your first bet loses, BetMGM returns your entire stake up to $1,500 in bonus bets.
The bonus bets are distributed based on your wager amount. If you bet $50 or more, you'll receive five bonus bets, each worth 20 percent of your qualifying wager. For example, if you wagered $1,500 on the Bills vs. Rams game and lost, you'd receive five $300 bonus bets totaling $1,500. If you wagered less than $50, you'll get one bonus bet matching your stake.
Key terms and conditions include:
- Bonus bets expire seven days after issuance.
- You must use each bonus bet before withdrawing any potential payout.
- BetMGM does not return your original stake when using bonus bets.
- You'll earn $50 in MGM Rewards Points whether you win or lose your first bet.

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 sports betting specialist 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.
