How the BetMGM bonus code works for MLB Wild Card betting
The BetMGM bonus code "SI1500" unlocks a welcome offer that returns your first bet in bonus bets if it loses. Here's what you need to know:
- You must make a minimum $10 deposit to qualify for this offer.
- Place your first real money wager on any market, including the MLB Wild Card games.
- 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 one bonus bet if you wagered less than $50.
- Bonus bets expire seven days after issuance.
- You'll earn $50 in MGM Rewards Points whether you win or lose your first bet.
For example, if you place a $1,500 bet on the Philadelphia at Atlanta game at 2 PM ET and lose, you'll receive five $300 bonus bets to use on other Wild Card matchups. If you place a $40 bet and lose, you'll get one bonus bet for $40. The bonus bets cannot be withdrawn as cash and must be used for additional wagers.
