Tuesday, Aug. 11 brings a full slate of baseball action and a marquee WNBA matchup, making it an ideal day to explore sportsbook promos at BetMGM. New users can claim $1,500 in bonus bets using the BetMGM bonus code "SI1500" when they sign up and place their first wager on any of Tuesday's games. The code is required to unlock this welcome offer.
How the BetMGM Bonus Code Works for Tuesday's Games
The BetMGM bonus code "SI1500" unlocks a welcome offer that returns your first bet in bonus bets if it loses, up to $1,500. Here's how it breaks down:
- You must make a minimum $10 deposit to qualify.
- Place your first real money wager on any market from Tuesday's MLB or WNBA slate.
- If your bet loses, you'll receive your entire stake back in bonus bets, up to $1,500.
- Bonus bets are issued as five separate $300 credits if you wagered more than $50, or as one bonus bet if you wagered $50 or less.
- All bonus bets expire seven days after issuance.
- You'll also earn $50 in MGM Rewards Points, regardless of whether your first bet wins or loses.
For example, if you place a $1,500 wager on the Mariners-Yankees game and it loses, you'll receive five $300 bonus bets to use on other Tuesday matchups. If you bet $40 on the Liberty-Fever game and lose, you'll get one $40 bonus bet instead. The bonus code "SI1500" is required at registration to claim this offer.
