How the BetMGM bonus code works for Argentina vs. Austria
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 the Argentina vs. Austria Group J match, and if it loses, BetMGM will return your full stake in bonus bets. It is one of the more generous welcome offers available at any major sportsbook right now.
Here is how the bonus bet structure breaks down based on your wager amount:
- If you wager $50 or more and lose, you receive five bonus bets, each worth 20% of your original stake. For example, a $1,500 losing wager on Argentina to win would return five $300 bonus bets, totaling $1,500.
- If you wager less than $50 and lose, you receive one bonus bet equal to your original stake.
- If your first bet wins, you collect your winnings as normal. A winning wager on Argentina at standard odds would pay out immediately.
- Bonus bets expire seven days after issuance and cannot be withdrawn directly. You must use them before accessing any potential payout.
- All new users receive $50 in MGM Rewards Points regardless of whether their first bet wins or loses.
There are two welcome offers available depending on your state. Users in most eligible states can claim the $1,500 First Bet using the BetMGM Sportsbook promo code SIBONUS50. Users in MI, NJ, PA, and WV can alternatively use the bonus code for BetMGM to place a $10 first wager and receive $150 in bonus bets if it wins, along with $50 MGM Rewards Points either way. The $150 bonus is issued as three $50 bonus bets, each expiring seven days from issuance.
MGM Rewards Points are part of BetMGM's loyalty program and can be redeemed in several ways, including bonus credits for digital play at BetMGM, MGM Rewards Points for use at MGM properties, Marriott Bonvoy Points, merchandise, and Gametime Vouchers. You can learn more about the program at the BetMGM Rewards page.
