Top March Madness Betting Bonuses
The best March Madness betting sites use enticing bonuses to attract bettors. Picking the right bonus can be challenging for two reasons.
First and foremost, you need a bonus that is big enough to meet your needs. Second, you want to avoid high rollover requirements because the NCAA Tournament is a relatively short event, and you only have 63 games to bet.
On the bright side, even with those two hurdles, there are plenty of exciting 2025 March Madness betting bonuses to choose from.
Best March Madness Sports Bonus SportsBetting.ag
Starting off my list of the top March Madness betting bonuses is the Shoot the Lights Out bonus at SportsBetting.ag. This sports bonus is exclusive to college basketball.
To qualify for this offer, you must bet at least $10 on the spread of a college basketball game. If your team covers and any player on your side hits six or more three-pointers, SportsBetting will double your winnings.
The maximum prize for this bonus is $75, and it can be redeemed unlimited times. SportsBetting has competitive odds for every game of March Madness, and its sleek UI makes betting on games a breeze.
