BetMGM Bonus Code 'SI1500' for NCAA Tournament Sunday Games

The BetMGM bonus code 'SI1500' offers new users up to $1,500 in bonus bets for Sunday's NCAA Tournament Round 2 matchups. This welcome offer is perfect for betting on Iowa vs. Florida, Utah State vs. Arizona, UCLA vs. UConn, and Texas Tech vs. Alabama. Check out the latest sportsbook promos available as of March 22.
How the BetMGM bonus code works for NCAA Tournament betting
New BetMGM users can claim this generous welcome offer by using the BetMGM bonus code 'SI1500' when registering. The promotion provides bonus bets back if your first wager loses, making it an excellent opportunity to bet on Sunday's NCAA Tournament games. You must make a minimum $10 deposit and place a real money wager to unlock your welcome bonus.
The offer varies by state, with most locations receiving the First Bet protection up to $1,500. However, users in Michigan, New Jersey, Pennsylvania, and West Virginia can opt for a different promotion: bet $10 and receive $150 in bonus bets if your first wager wins. Both versions require the same BetMGM promo code 'SI1500' during registration.
Key terms and conditions include:
- Minimum $10 deposit required to qualify.
- If you wager more than $50 and lose, BetMGM awards five bonus bets worth 20% of your qualifying wager each.
- Wagers under $50 receive one bonus bet equal to your stake if the bet loses.
- Bonus bets expire seven days after issuance.
- BetMGM does not return your stake when using bonus bets.
For example, if you place a $500 first bet on Iowa to upset Florida and it loses, you would receive five $100 bonus bets totaling $500. If UCLA defeats UConn in your winning scenario, you keep your original winnings plus any additional payouts. This BetMGM Sportsbook promo code offer provides excellent value for NCAA Tournament betting.
