How the BetMGM bonus code works for MLB Opening Day betting

New BetMGM users can claim this generous welcome offer by using the BetMGM bonus code 'SI1500' when registering. The promotion provides up to $1,500 back in bonus bets if your first real money wager loses. This offer applies to any MLB Opening Day matchup, including the highly anticipated showdowns featuring Paul Skenes, Jacob Misiorowski, and Yoshinobu Yamamoto.

The terms and conditions include several important details:

  • Minimum $10 deposit required to activate the bonus.
  • First bet protection covers wagers up to $1,500.
  • Bonus bets expire seven days after issuance.
  • Wagers over $50 receive five separate bonus bets worth 20% each of the original stake.
  • Wagers under $50 receive one bonus bet equal to the stake amount.

For example, if you place a $1,000 wager on the Dodgers-Diamondbacks game featuring Yamamoto and it loses, you would receive five $200 bonus bets totaling $1,000. Alternatively, if you bet $500 on Paul Skenes and the Pirates against the Mets and lose, you get five $100 bonus bets. Winners keep their original winnings plus the stake, making this an excellent opportunity for Opening Day action.
