How the BetMGM bonus code works for Seahawks vs. Chiefs

The BetMGM bonus code SI1500 gives new bettors a straightforward welcome offer. You'll deposit a minimum of $10 and place your first real money wager on any market, including the Seahawks vs. Chiefs matchup. If your bet loses, BetMGM returns your entire stake as bonus bets, up to $1,500.

Here's how the bonus structure works:

  • If you wager more than $50, you receive five bonus bets, each worth 20 percent of your qualifying wager.
  • If you wager $50 or less, you receive one bonus bet.
  • For example, if you wagered $1,500 on the Seahawks vs. Chiefs and lost, you would receive five $300 bonus bets totaling $1,500.
  • Bonus bets expire seven days after issuance.
  • You also earn $50 in MGM Rewards Points, which you can use for bonus credits for digital play at BetMGM, MGM Rewards Points, Marriott Bonvoy Points, merchandise, or Gametime Vouchers.

When you win your first bet on Seahawks vs. Chiefs, you keep your winnings immediately. When you lose, the bonus bets arrive in your account to use on future wagers. You cannot withdraw bonus bets as cash, but you must use them before withdrawing any winnings generated from them. The code SI1500 is required to claim this offer.
