BetMGM Bonus Code Delivers Maximum Value for Warriors vs Mavericks

The BetMGM bonus code COVERS1550 offers new customers substantial betting power for Thursday's NBA action. After making a minimum $10 deposit and placing your first real money wager, you'll receive your stake back in bonus bets if your initial bet loses, up to $1,500. Additionally, all new users receive $50 in bonus bets win or lose.

Consider backing the Warriors to bounce back after their 145-127 loss to Toronto, especially with Jonathan Kuminga returning to action after 16 consecutive DNP-CDs. If you wager $100 on Golden State and they lose, you'll receive $100 in bonus bets plus the guaranteed $50 bonus. Should Dallas continue their winning streak with another victory, a $500 bet on the Mavericks that loses would return $500 in bonus bets alongside your $50 bonus.

Key terms include:

  • Bonus bets expire after seven days
  • Available to new users in eligible states only
  • Minimum $10 deposit required
  • Bonus bets cannot be withdrawn directly
