How the BetMGM bonus code works for Tuesday's games

The BetMGM bonus code "SI1500" unlocks a straightforward welcome offer for first-time users. After you register and make a minimum $10 deposit, place your first real money wager on any of Tuesday's WNBA or MLB matchups. If your initial bet loses, BetMGM returns your entire stake as bonus bets, up to $1,500.

Here's how the bonus structure works:

  • If you wager $50 or less and lose, you receive one bonus bet matching your stake.
  • If you wager more than $50 and lose, you receive five bonus bets, each worth 20 percent of your qualifying wager.
  • For example, if you wagered $1,500 on the Dodgers versus Cubs matchup and lost, you would receive five $300 bonus bets.
  • Bonus bets expire seven days after issuance.
  • You also earn $50 in MGM Rewards Points regardless of whether you win or lose.

MGM Rewards Points can be redeemed for bonus credits for digital play at BetMGM, additional MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers. Learn more about the program at https://www.nj.betmgm.com/en/p/betmgmrewards.

When you use the bonus bets from a losing wager, remember that BetMGM does not return your stake when using bonus bets. You keep only your winnings. This means if you place a $300 bonus bet on Tuesday's games and win $400, you receive $400 in withdrawable funds, not $700.
