BetMGM bonus code COVERS delivers $1,500 First Bet for Mavericks vs Thunder

The BetMGM bonus code COVERS unlocks a generous First Bet offer worth up to $1,500 for new customers. After registering and making a minimum $10 deposit, place your first real money wager on any market, including the Mavericks vs Thunder game. If your initial bet wins, you keep the profits and can withdraw them immediately.

However, if your first wager loses, BetMGM returns your stake as bonus bets up to $1,500. For example, if you bet $100 on Cooper Flagg to score over 25.5 points and he falls short, you receive $100 in bonus bets. Wagers over $50 are split into five equal bonus bets, while smaller amounts result in a single bonus bet. All bonus bets expire after seven days and cannot be withdrawn directly.

This offer is available to new users in Arizona, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, North Carolina, Nevada, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, Wyoming, plus Washington D.C. and Puerto Rico.
