How the BetMGM bonus code works for Texas vs. Oklahoma
The BetMGM bonus code "SI1500" unlocks a welcome offer that returns your entire first bet in bonus bets if it loses, up to $1,500. Here's how it breaks down:
- Make a minimum $10 deposit to qualify for the offer.
- Place your first real money wager on any market for the Texas vs. Oklahoma game.
- If your bet loses, you'll receive bonus bets equal to your stake, up to $1,500.
- Bonus bets expire seven days after issuance.
- You'll also earn $50 in MGM Rewards Points, regardless of whether you win or lose.
For example, if you place a $1,500 bet on Texas vs. Oklahoma and it doesn't win, you'll get five bonus bets worth $300 each. If you wager less than $50, you'll receive one bonus bet. You can then use these bonus bets on other games throughout the week. When you use bonus bets, your stake doesn't return if you win, but your winnings do.
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 https://www.nj.betmgm.com/en/p/betmgmrewards.

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.
