BetMGM Bonus Code Offers

Use the BetMGM bonus code BOOKIESMARCH when you sign up to unlock $200 in Bonus Bets instantly (with a qualifying $10 wager on the big college hoops tournament). You'll get the bonus even if your $10 wager loses.

Bettors who register for a new account with the BetMGM bonus code BOOKIES will instead receive a first-bet bonus up to $1,000. That means they can choose from any set of odds in any sports betting market, place a real-money wager up to $1,000 on its outcome, and receive A) cash profit on a win or B) bonus bets equal to your original wager on a loss. 

Losing bettors will receive five bonus bets in equal 20% denominations of their original losing wager (for example, a losing $600 wager would yield five $120 bonus bets). Note that if your first wager loses and is less than $50, you’ll receive a single matching bonus bet back in return.
