BetMGM Bonus Code ROTOSPORTS $1500 First-Bet Offer Terms & Conditions
To show you how to use the first bet offer with the BetMGM bonus code ROTOSPORTS, let's say you decide to bet $100 on Michigan -2.5 points to win vs San Diego.
If the Wolverines cover, you will get a payout of $189.29 ($89.29 in winnings plus your initial $100 stake). If Michigan doesn't cover, the BetMGM bonus code ROTOSPORTS will give you a bonus bet refund of $100. BetMGM pays out first bet losses of $50 or more through five bonus bets, so you will get five $20 bonus bets in this case. Lose less than $50 and it's a single bonus bet refund.
There are no betting odds restrictions with the first bet offer, so you can also go for upside via a moneyline pick such as Utah State at +170 odds to upset UCLA. A win there could afford a solid payout, and you can go for it with the first bet protection from the BetMGM bonus code ROTOSPORTS.
