BetMGM Bonus Code Details for $1,500 First Bet
The BetMGM bonus code COVERS provides new customers with substantial protection on their first sports bet. This welcome offer allows you to wager up to $1,500 on any market, including Tuesday's pitching duel between the Yankees and Mariners. If your initial bet loses, BetMGM returns your entire stake as bonus bets, giving you another chance to capitalize on the action.
The bonus structure varies based on your wager amount. Bets over $50 receive five separate bonus bets, each worth 20% of your original stake, while smaller wagers receive one bonus bet equal to your loss. For example, if you bet $1,000 on the Yankees to win and they fall short, you would receive five $200 bonus bets totaling $1,000. These bonus bets expire after seven days, providing ample time to use them on upcoming games.
Key terms include:
- Minimum $10 deposit required
- Bonus bets expire seven days after issuance
- Available in most states where BetMGM operates
- Bonus bet winnings exclude the stake amount
Given the strong pitching matchup and both teams' offensive struggles, this offer provides excellent value whether you back the under, a low-scoring game, or either starter to dominate. The Yankees' 0.86 ERA and Mariners' 1.84 ERA suggest another tight contest where every run matters.
