How the BetMGM bonus code works for playoff betting

The BetMGM bonus code "SI1500" unlocks a welcome offer designed for new users placing their first wager on any of Wednesday's Divisional Series games. Here's how it works:

  • Make a minimum $10 deposit to qualify for the promotion.
  • Place your first real money bet on any market for Cleveland at Chicago, Los Angeles versus Atlanta, Tampa Bay at New York, or Milwaukee against San Diego.
  • If your bet loses, you receive your entire stake back as 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  • Bonus bets expire seven days after issuance and cannot be withdrawn as cash.
  • You receive $50 in MGM Rewards Points, which are bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers.

For example, if you place a $500 bet on one of Wednesday's playoff games and it loses, you'll get five $300 bonus bets back to use on future wagers. If you place a $40 bet and it loses, you'll receive one $40 bonus bet. The promotion applies only to your first wager, so make it count on one of the four matchups happening Oct. 7.
