Not needing to enter one at the other March Madness sportsbooks could be a factor to consider when determining which you find to be the best site to bet on March Madness.

💻 Which March Madness Betting Site Provides the Best Odds?

The answer to this question certainly depends on which betting market you’re wagering on and the specific time at which you’re doing so. In other words, it depends, but there is a way to ensure that you’re always getting the best prices possible.

This is done by simply joining each of the March Madness betting sites we’ve provided for you. That way, you can compare the lines and odds of the wager you’d like to make and choose the best one for that particular betting market. Lines and odds can also fluctuate leading up to an event, so always keep a close eye on those values before officially submitting your wagers.

💻 How Do March Madness Betting Sites Work?

These March Madness betting sites work much like you’d expect, and our guide as to how to sign up helps with that as well. Some may vary in terms of having “NCAAB” or “College Basketball,” but finding the proper link to navigate to will be readily available to you. That is especially true in-season, when college basketball becomes one of the most popular sports to wager on.

🔢 Popular March Madness Bet Types Offered by Sportsbooks

Year by year, the ways and available betting markets continue to expand, but some remain the tried and true. Below, we’ve listed the bet types that will seemingly always be a staple in the sports betting world.

🏀 Point Spread

The first of the standard markets that you’ll see populate when to navigate to the upcoming matchups at these March Madness betting sites is the point spread. This is arguably the most common approach, as it is the great equalizer. Oftentimes, matchups have a clear favorite, so predicting how much a team will win by or how close a team can keep a game is the best determination of success.

🏀 Money Line

For those matchups that don’t have significant point spreads and are anticipated to be tightly-contested battles, money lines are often the approach. This betting market simply means you are predicting who will win the game, regardless by how much. It’s as straightforward as it gets, which is why it remains one of the most popular betting markets.

🏀 Game Total (Over/Under)

The last of what is considered the standard markets is the total, or over/under. This bet type is simply predicting whether a game will have more or less points scored than a number set by oddsmakers. For example, a game could have a total set at 175.5 points, and you can bet over or under that number.

🏀 Player Props

Finally, arguably the most popular way to approach matchups outside of those three standard markets is player props. These are just as they sound - players have specific values set for various markets, such as points scored, rebounds, assists and so much more. Much like a total, you’ll wager over or under a set value. There are also yes/no player props, such as a player recording a double-double or not.

⚖️ Are These March Madness Sportsbooks Legal and Legit?

As stated when we broke down our criteria in what made these the top March Madness sportsbooks, each one is absolutely legal and legit. You can breathe easy knowing that no matter which one you personally consider to be the best online betting site for March Madness, they are all 100% safe and secure.

When PASPA - the law banning sports betting - was overturned in 2017, individual states were then able to determine the legality of sports wagering. So far, here are the states that have legal online sports betting:

• Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Vermont, Virginia, West Virginia or Wyoming
