BetMGM Big Fly Fridays - Win a Share of $100K in Bonus Bets
BetMGM Big Fly Fridays
Every Friday, BetMGM is offering baseball bettors a chance at huge prizes. Through their Big Fly Fridays promotion, if the player a user bet on to hit an anytime homerun has the longest dinger of the day, they'll be eligible for a share of $100,000 in bonus bets.
Similar to FanDuel's Dinger Tuesdays or Bet365's Saturday Sluggers, this promotion is a big win for those of you who get a kick out of betting on home run hitters. In fact you could probably manage to find a promo 7 days a week at this point!
To join, you need to sign up with BetMGM. On a Friday, place a home run bet with at least +100 odds, apply the Big Fly Fridays Qualifying Token, and wager at least $10.
Only the first bet using the token that day, placed by 10:00 pm EST, qualifies. That means, you're cut off once the west coast games start.
Any bonus bets you win as part of this promotion must be used within 7 days.
Big Fly Fridays are an awesome promotion this season, allowing baseball to grab a potentially huge share of bonus bets, especially when combined with the offers from other operators.
