We’ll cover some of those deals later on, but first, let’s focus on which online sportsbooks are best for gambling on NCAA March Madness odds:

Types of March Madness Betting Lines

Given the almost impossible odds of picking a perfect March Madness bracket, you'll be much better off gambling on the NCAA tourney in the traditional sense. Here's the type of betting options you'll have:

March Madness Moneyline Betting

Moneyline is the simplest bet in the book. Here, you're simply picking the team that will win straight up. Each team will have March Madness odds to win (which we cover in the next section) so it's a 50-50 chance.

March Madness Spread Betting

The point spread March Madness is also concerned with which team will win, but this bet cares by how much points a team wins or loses by. That's because a "handicap" is added to the favorite and underdog.

The handicap is measured in points. Therefore, if you hear the spread is five points, it means the favorite needs to win by six or more to cover. Whereas the underdog can either win outright or lose by four or fewer points to cover their spread.

Let's say the game in the above example ends with the favorite winning by exactly five, then the bet is considered a "push." This effectively means it's a tie and all money is returned to bettors on both sides.

March Madness Over/Under Betting

Betting on how much points two teams will combine for is a favorite among bettors. Bookies pre-set a point figure and it's on players to choose "under" or "over" that sum. Like spreads, if the final point totally matches the over/under figure exactly, then the wager ends in a push.

March Madness Prop Betting

More or less, props are side bets on mini-outcomes within a March Madness game. Many deal with individual players — such as how many rebounds they'll grab by game's end, for example. But there's also team-specific props like how many turnovers they'll commit.

March Madness Point Future Betting

Futures bets are focused on long-term outcomes such as who'll win the national championship. Odds on winning March Madness are available almost year-round and it's the most popular bet type with bettors to make. Given how hard it is to pick the exact winner, futures are very high-risk, high-reward plays.

Understanding March Madness Betting Odds

If you've ever bet on any other sport before, you'll have no trouble with Vegas odds for March Madness. That's because they're carbon copies of one another. If you are versed in this, you can skip ahead. But for the unfamiliar players just getting into betting, here's how March Madness Vegas lines work:

By and large, most sportsbooks use the American odds system, as opposed to decimal or fractional lines. Odds like these are displayed as a whole number, with either a negative (-) or positive sign (+) attached to it. The symbol denotes whether one side is the favorite (minus sign) or the underdog (plus sign).

Moreover, the exact odds listed indicates just how much of a favorite or underdog one side is, which has consequences on the payout. Let's use an example to illustrate the point.

Say Syracuse and Kansas are meeting in the Sweet 16 round. If you're betting the moneyline, the Orange might have +175 odds. As the underdogs, bettors stand to make $175 for every $100 wagered on Syracuse if they do pull off the upset. In turn, the Jayhawks could have a -205 line. As the favorites, players earn a lesser payout if Kansas wins, which is only a $100 profit for every $205 wagered.

The above example applies to moneylines and futures betting. However, spreads, over/unders, and props are a little different. That's because most these lines will always be 110 going both ways.
