BetMGM is tying its latest welcome offer to Monday Night Football, with new customers able to get up to $1,500 in bonus bets for Rams vs. Bills on Oct. 12 by using bonus code SI1550.
The promotion is available to first-time users in eligible locations and is built around a simple structure: make a first wager, and the offer applies if that bet loses. BetMGM is marketing the deal as a welcome offer for new customers, making it relevant only to bettors who have not yet signed up and are in one of the approved markets.
How the SI1550 offer works
The bonus-code promotion gives new users up to $1,500 in bonus bets tied to their first wager on the Buffalo Bills and Los Angeles Rams matchup. The game is scheduled for Oct. 12 on Monday Night Football, giving the offer a clear time stamp and a specific event to target.
The key detail is that the first bet must lose for the bonus-bet offer to activate. That makes the promotion straightforward, but it also means the value is limited to those making their first BetMGM wager and only in the locations where the offer is available.
Important terms for bettors
The offer is for users 21 and older. As with any sportsbook promotion, bettors should review the available support and problem-gambling resources if needed, including 1-800-GAMBLER, 1-800-MY-RESET, 877-8-HOPENY, 467369, 1-800-327-5050, 1-800-NEXT-STEP, 1-800-BETS-OFF and 1-800-981-0023.
For fans looking at Rams Vs Bills through the lens of a promo rather than just a prime-time matchup, the takeaway is simple: this is a date-specific BetMGM welcome offer built around a marquee NFL game, and the SI1550 code is the key to unlocking it.
