BetMGM Bonus Code SIBONUS50: Get Up to $1,500 in Bonus Bets if Your First Bet Loses on MLB & WNBA Saturday
Saturday, August 1 brings a stacked slate of baseball and basketball action, and new bettors can capitalize on the action with the BetMGM bonus code "SIBONUS50." This welcome offer lets you claim up to $1,500 in bonus bets if your first wager loses, plus $50 in MGM Rewards Points. Check out our sportsbook promos for more opportunities to maximize your bankroll.
How the BetMGM bonus code works for Saturday's MLB and WNBA action
The BetMGM bonus code "SIBONUS50" is designed to give new users confidence when placing their first wager on Saturday's 15-game MLB slate or the two WNBA matchups. Here's what you need to know about this welcome offer:
- Make a minimum $10 deposit to qualify for the promotion.
- Place your first real money wager on any sport or market, including Saturday's Cardinals-Blue Jays, Yankees-Cubs, Red Sox-Dodgers, or either WNBA game.
- If your bet loses, you'll receive your entire stake back, up to $1,500, in bonus bets.
- Bonus bets are issued as five separate $300 credits if you wagered $1,500, or as a single bonus bet if you wagered less than $50.
- Your bonus bets expire seven days after issuance.
- You'll also receive $50 in MGM Rewards Points, win or lose.
Let's say you place a $1,500 wager on the Red Sox-Dodgers matchup Saturday night and the bet loses. You'd receive five $300 bonus bets back, giving you another chance to win on Sunday's slate or throughout the week. Conversely, if you bet $30 on the Aces-Sky WNBA game and lose, you'd get one $30 bonus bet to use on future wagers.
