BetMGM Bonus Code Offers for New Users

BetMGM Sportsbook offers new customers two distinct welcome offers, depending on their location. The primary offer allows new users to claim up to $1,500 in bonus bets if their first wager loses when using the BetMGM bonus code "COVERS." This offer is available in most states where BetMGM operates, including Arizona, Colorado, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Missouri, Mississippi, North Carolina, Nevada, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Wyoming.

In select states, including Colorado, Michigan, New Jersey, Pennsylvania, and West Virginia, new users can instead opt for a "Bet $10, Get $150" promotion using the bonus code "COVERSBONUS." This offer provides $150 in bonus bets if the initial $10 wager wins. Both promotions require a minimum $10 deposit and have specific terms regarding bonus bet distribution and expiration.

How to Claim BetMGM Welcome Offers

To claim either BetMGM offer, new users must register for an account using the appropriate bonus code during sign-up. After completing identity verification and making the required minimum deposit, users can place their qualifying wager on any sports market. For the $1,500 offer, bonus bets are returned if the first bet loses, distributed as either one bonus bet (for wagers under $50) or five equal bonus bets (for wagers over $50). All bonus bets expire seven days after issuance and cannot be withdrawn directly.

Caesars Sportsbook Promo Code for Profit Boosts

Caesars Sportsbook offers new customers a unique welcome promotion that provides 10 profit boost tokens after placing a qualifying first wager. Using Caesars Sportsbook promo code "COVERSBONUSDYW," new users can earn these valuable tokens by placing a minimum $1 wager on any eligible sports market.

The promotion requires users to place their first qualifying wager within 30 days of account opening. Certain bet types are excluded from qualifying, including wagers using existing bonus funds, Super Boosts, Round Robin wagers, and bets with odds shorter than -500. The profit boost tokens provide users with the flexibility to enhance their potential returns on future wagers throughout the tournament.

How to Claim the Caesars Profit Boost Offer

New Caesars Sportsbook customers must create an account using the promo code "COVERSBONUSDYW" and make a minimum deposit of $10. After placing a qualifying wager of at least $1 on any eligible sports market, users receive 10 profit boost tokens regardless of whether their initial bet wins or loses.
