BetMGM Bet $10 Get $150 in Bonus Bets if your Win

Score big on your first bet with BetMGM. Sign up with BetMGM, bet at least $10 on any game and win $150 in Bonus Bets if your bet wins. This is a great offer to pad your bankroll before the National Championship Tournament kicks off. The most important thing to keep in mind with this offer is you only get one shot at it, so our suggestion is to find the "surest thing" you can in available markets. You're not looking to win a big payout on your $10 bet, you just want something that will win. Look for the lowest number you can, something like -1350. You may only win $0.74 on your $10 bet but you'll have $150 more in your bankroll for wagers with higher payout potential.
