New BetMGM users can secure up to $1,500 in bonus bet protection with the BetMGM bonus code COVERS. This offer provides full stake protection on your first wager, returning your entire bet amount in bonus bets if it loses. The operator also offers an alternative promotion in select states where a winning $10 bet returns $150 in bonus bets using code COVERSBONUS.

Key terms include a minimum $10 deposit requirement and a seven-day expiration on bonus bets. If your first bet exceeds $50 and loses, BetMGM awards five separate bonus bets worth 20% of your stake each. Smaller losing bets receive a bonus bet equal to the stake.

The Caesars Sportsbook promo code "COVERSBONUSDYW" delivers 10 profit boost tokens after placing your first $1 wager.
