Best March Madness Betting Sites 

While also March Madness betting sites have the same functionality—a spot for bettors to legally place bets and earn winnings—they are not all created equal. Certain sports betting sites are better for certain types of players, and some welcome bonuses will appeal more to one person than it does another.

That’s why we’re here. We’ve analyzed all March Madness betting apps to let you know what we like about them, where they can improve, and how you the bettors can make the most out of your experience—including unlocking everything that comes with the welcome bonus after you register for a new account. Here’s what you need to know as you get ready to start playing.

Features At Top March Madness Betting Sites

March Madness New User Sportsbook Promos

All March Madness betting sites will offer new bettors some kind of sportsbook promo code that unlocks a welcome bonus. These welcome bonuses all provide bettors with something that enhances the sports betting experience and increases potential payouts. They’re all similar in that respect—but all are unique in their own right.

The two most popular forms of welcome bonuses are first-bet bonuses and bet-and-get offers. First-bet bonuses allow bettors to place a first real-money wager knowing that if that wager loses, they’ll receive matching bonus bets and a second chance to get their bets correct. 

Of course, a winning first wager earns cash profit like it would any other bet. Bet-and-get offers work like this: Place a small wager and automatically receive bonus bets that get transferred into your account. There’s less upside here but also less risk—making it a great option for all players.

Where Can I Use March Madness Betting Sites?

Online sports betting is available in more than 30 U.S. states, and that’s great news for players ready to get their hands on all the March Madness betting sites and the odds they provide. Here’s a look at the states where you can legally place bets on college hoops and March Madness:

Odds On March Madness Betting Sites

We always recommend registering with multiple online sportsbooks, not only because you can take advantage of additional welcome bonuses but also because you can shop odds and make sure you’re getting the best value on your bets. 

Getting one team’s spread at -110 vs. -115 may not feel like a big difference, but that’s an additional $5 you’re wagering each time to win $100 ($115 vs $100), and that really adds up over time. 

While most odds are going to be similar—if not identical—it’s always worth looking around at multiple March Madness betting sites so you are sure you’re getting the best deal each time you place a bet.

Live Betting On March Madness Betting Sites

We know how quickly NCAA Tournament can change in an instant. That means that betting does not end once games begin. Live betting is a major part of all online sports betting sites—and especially during March Madness. 

It’s important to have a website (and strong internet connections) because these odds change in real time, and a missed or made shot will shift the odds in a matter of seconds. 

All major operators have live-betting functionality and make it easy for bettors to wager in-game. Realistically, it’s easier to place live bets on mobile betting apps but a fast computer and internet will make it possible on betting sites, too.
