BetMGM Bonus Code SIBONUS50: Get Up to $1,500 in Bonus Bets if Your First Bet Loses on Portugal vs Spain

Portugal and Spain are set to clash in a Round of 16 showdown on Monday, July 6, and new bettors can take advantage of a massive welcome offer. The $1,500 in bonus bets is available when you use the sportsbook promos code SIBONUS50. This BetMGM bonus code unlocks a welcome offer that returns your entire first wager in bonus bets if it loses, up to $1,500.
How the BetMGM bonus code works for Portugal vs Spain
The BetMGM bonus code SIBONUS50 is designed to give new users a substantial cushion on their first wager. After you register and deposit at least $10, you can place your opening bet on any market for the Portugal vs Spain match. If your bet loses, BetMGM returns your stake as bonus bets, up to $1,500.
Here's how the bonus structure works:
- If you wager $50 or less and lose, you receive one bonus bet equal to your stake.
- If you wager more than $50 and lose, you receive five bonus bets, each worth 20% of your qualifying wager.
- For example, if you bet $1,500 on Portugal to win and lose, you'd receive five $300 bonus bets.
- Bonus bets expire seven days after issuance and cannot be withdrawn as cash.
- You'll also earn $50 in MGM Rewards Points, regardless of whether your first bet wins or loses.
This offer applies to any market for the Portugal vs Spain match, whether you're backing a side, betting the over/under, or wagering on player props. The key is that your first real money wager must lose to trigger the bonus bets. If your initial bet wins, you keep your winnings but don't receive the bonus bets component. MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers.
