How the BetMGM bonus code offer works for Argentina vs. Algeria
The BetMGM bonus code SIBONUS50 unlocks a First Bet offer worth up to $1,500 for new users. Place your first real-money wager on Argentina vs. Algeria, and if it loses, BetMGM will return your entire stake in bonus bets. This is one of the more generous welcome offers available at any major sportsbook.
Here is a closer look at how the offer breaks down:
- New users must deposit a minimum of $10 to qualify.
- Place your first real-money wager on any market, including Argentina vs. Algeria.
- If your first bet loses, you receive your stake back in bonus bets, up to $1,500.
- Wagers over $50 are returned as five bonus bets, each worth 20% of your original stake. For example, a $1,500 losing wager returns five $300 bonus bets.
- Wagers of $50 or less are returned as a single bonus bet.
- Bonus bets expire seven days after issuance.
- All new users receive $50 in MGM Rewards Points, regardless of outcome.
To put this in context, say you back Argentina to win at -200 and wager $200. If Argentina wins, you collect your payout immediately. If the result goes against you, BetMGM returns your $200 stake as bonus bets, giving you another opportunity to wager on the remaining Group J matches or any other market on the platform.
Users in Michigan, New Jersey, Pennsylvania, and West Virginia also have access to an alternate offer using bonus code SIBONUS50. Place a $10 first bet, and if it wins, you receive $150 in bonus bets in addition to your winnings. The bonus is issued as three $50 bonus bets, each expiring seven days from issuance. Win or lose, you still earn $50 in MGM Rewards Points.
MGM Rewards Points are part of the BetMGM Rewards program, which lets you earn and redeem points across a range of options. These include bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers for live events. You can learn more about the program at the BetMGM Rewards page.
