How the BetMGM bonus code works for Lakers vs. Mavericks betting

The BetMGM bonus code SIBONUS50 provides new customers with first bet protection up to $1,500 plus $50 in MGM Rewards Points. This BetMGM promo code allows you to place your initial wager on any Lakers vs. Mavericks betting market with confidence. If your first bet loses, BetMGM returns your stake as bonus bets up to the maximum amount.

Key terms for this BetMGM Sportsbook promo code include:

  • Minimum $10 deposit required to activate the offer.
  • Bonus bets expire seven days after issuance.
  • Wagers over $50 receive five 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 bet $500 on the Lakers to cover the spread against Dallas and lose, you would receive five $100 bonus bets totaling $500. If you bet $25 on Luka Dončić to score over his points total and lose, you would get one $25 bonus bet. MGM Rewards Points can be redeemed for bonus credits, merchandise, Marriott Bonvoy Points, or Gametime vouchers through the BetMGM rewards program.
