BetMGM Bonus Code Delivers $1,500 Protection for Celtics vs Mavericks

This offer returns your stake as bonus bets if your initial wager loses, up to a maximum of $1,500. The promotion applies to any sports market, making it perfect for betting on the Celtics vs. Mavericks game.
Boston enters this contest as heavy favorites despite Dallas rookie Cooper Flagg's recent hot streak. The Celtics' 31-18 record positions them third in the Eastern Conference, while the Mavericks sit 11th in the West at 19-30. If you bet $100 on Boston to cover the spread and they fail to do so, you'll receive $100 in bonus bets to use on future wagers.
Key terms for this promotion include:
- Minimum $10 deposit required to activate the offer
- Bonus bets expire seven days after issuance
- Wagers over $50 receive five separate bonus bets worth 20% each
- Available in eligible states including AZ, CO, IL, IN, IA, KS, KY, LA, MD, MA, MI, MO, MS, NC, NV, NJ, NY, OH, PA, TN, VA, WV, WY, DC, and PR
For example, if you place a $500 bet on Dallas to upset Boston and the Mavericks lose, you'll receive five $100 bonus bets totaling your original stake. These bonus credits give you additional opportunities to profit from NBA action throughout the week.
