Best March Madness Promos in Illinois

PointsBet Sportsbook

• March Madness promo:Bet $20 on any team, win $150 if they score a point
• March Madness promo: Bet $20, win $300 if Gonzaga (or any team) wins in Round 1
• Deposit match:Deposit $250, Get $250 FREE

Starting off with a bang, PointsBet has two options for you to make some easy cash in Round 1.

Gonzaga will be a giant favorite in its first-round matchup. I'm talking, like, -10000 range. At PointsBet, though, you can bet them at +1500! In fact, you can pick any moneyline of your choice as your first bet, no matter the matchup, and win $300 on a $20 bet! 

Or, if you'd prefer an even more sure option, you can turn that $20 into $150 if the team of your choice scores a single point in their game!

FanDuel Sportsbook

• March Madness promo: Bet Michigan State at +99.5 (and rising!) vs. UCLA

You're not going to find much more of a lock than this one.

FanDuel Sportsbook is 'Spreading the Love' Thursday night for Michigan State vs. UCLA, increasing the MSU spread as more bettors take advantage of the promo.

The Spartans are up to +99.5 (and beyond!) now, so there's no chance they don't cash this bet, and there's no reason to wait, as your bet will be graded at the closing number anyway.
