How to Bet on March Madness Online

First, you need to sign up for a sportsbook. To do this, you need to enter your personal information and have your geolocation tracked to ensure you are in a legal sports betting state. Also, it is important to compare sportsbooks to find the best promotions, odds, lines, betting markets, and features that fit your betting strategy.

Once you have signed up for a sportsbook, check to see if there are any promotions available. Promo codes can be automatically claimed or require a code to be entered. It is essential to read the terms and conditions, as some promotions may require a qualifying bet or a minimum deposit to unlock bonus bets. 

When using a promotion, you need to understand how it works. Some promotions are game-specific, while others may have a percentage-based deposit match bonus. For instance, if a sportsbook offers a 25% deposit match bonus and you deposit $100, you will receive $25 in bonus bets. 

Now, you are ready to kick off your betting experience with your first wager. Don’t rush. Find the bet you like and add it to your bet slip. You can place bets by visiting the sports betting site or getting March Madness betting apps.

There is a long list of bet types and markets you will find with an online sportsbook and mobile betting. Here are a few of the bet types you will see when you check out betting sites for the March Madness tournament.


A moneyline bet is when you place a wager on a team to win the game. It’s pretty simple. Pick the team you believe will win. It’s one of the easiest types of bets to understand. Scan the March Madness games, check the odds, and bet on a team to win.

Moneyline bets have odds that are negative for favorites and positive for the underdog. For example, you see a 2023 March Madness game between Texas and Saint Peter’s. Texas is a -450 favorite. This means you would need to bet $450 on Texas to win $100.

Point Spread

A point spread bet is looking at the margin of victory or defeat in a given game. The favorite is given a point total they are expected to win by. The point spread for a favorite is listed as a negative. This means the team has to win by more than the point spread to cover. It’s an extremely popular bet type on online betting sites.

For example, you are ready to bet on the NCAA Division I Tournament. You see Kansas is a -10.5 favorite. If you bet on Kansas, they have to win by 11 points or more to cover the spread and for you to win the bet. The odds for a spread bet are usually around -110 on both sides.


A total bet is also called an over/under. You are betting on the total number of points scored by both teams combined. A sportsbook will set a total line and you can bet whether the teams will score over or under that market.

For example, you want to get in on the betting action for a college basketball game. You see the total for the Kansas-Miami game is 145.5 points. You place a bet on the over. That means you need 146 points or more scored in the game to win. If the game ended 71-70, your bet would lose because that’s only 141 total points.

Prop Bets

A prop bet is a type of wager that focuses on a specific outcome within a game. It’s important to note that the outcome may not necessarily be tied to the final result of the game. Many people find these bets more enjoyable since they offer a unique way to engage with the game.

Sportsbooks offer a wide range of March Madness prop bets, including outcomes for players, teams, and specific game events. You can bet on a variety of outcomes, such as which player will score the most points, who will have the most rebounds, which team will reach 15 points first, and more.


A futures bet is a wager on an event taking place down the road. For college basketball, you can bet on which team will win the National Championship at any point throughout the year. There are also March Madness futures.

The odds are constantly changing based on what is happening during the season. Another common futures bet is betting on a team to reach the Final Four. 

Live Betting

In-game betting has taken off in recent years. Sports bettors can keep track of the action and place wagers on what’s happening in that moment. The top online sports betting sites have long lists of odds and markets for in-game betting. The odds and lines change quickly based on the action. Millions of people will be placing in-game bets on the 2023 NCAA Tournament.

Online Sports Betting Offers and Promotions

There is no shortage of March Madness promotions and offers from sportsbooks. Sportsbooks have these offers to entice new users to sign up for their platform. There are common bonuses and offers you will see as you try to cash in on March Madness betting. Here are a few you will see when you get set to bet on March Madness.

Bonus Bets

College basketball betting sites often offer bonus bets as part of their promotions for new users. These types of promotions are easy to understand and typically require no deposit of your own money. With bonus bets, you can take more risks with your wagers without the worry of losing your own money if the bet doesn’t win.

It’s important to note that bonus bets may only be valid for specific markets or events in some cases. However, in most cases, you can use them on any market you want, as long as you meet certain minimum odds requirements. This flexibility allows you to use your bonus bets in a way that best fits your betting strategy.

Overall, bonus bets are a great way to maximize your college basketball betting experience. They allow you to take more chances without putting your own money on the line, making it easier to enjoy the excitement of the tournament. Just be sure to read the terms and conditions of each bonus offer, so you know exactly how and where to use your bonus bets.

Second Chance Bets

Sportsbooks use different terms to refer to a type of bet that covers your first bet if you lose. These terms include No Sweat First Bet, Second Chance Bet, First Bet Insurance, and more. Despite the different names, they all mean the same thing: you’ll receive betting credit to cover your first bet’s loss.

Bet insurance is a common tool used by betting sites to entice new customers. With this feature, you can continue betting even if your first wager doesn’t win, giving you a second chance to win big. So if you’re hesitant to place your first bet, bet insurance can provide the peace of mind you need to take that first step.

Deposit Match

Deposit-match bonuses are a popular signup bonus when joining online betting sites. This type of bonus works by matching the amount of your initial deposit with bonus money. For example, if you deposit $100, the betting site may provide you 25 percent of the amount in bonus funds for you to use when placing bets.

It’s worth noting that there is typically a limit on the amount of bonus money you can receive from the betting site. Additionally, the bonus money often comes with rollover requirements, meaning you must place a certain number of bets before you can withdraw the bonus money.

Odds Boost

Although not as common as other promotions like bonus bets or deposit bonuses, odds boost offers are still valuable tools for increasing your profits when betting. These offers involve betting sites increasing the odds of a particular market or selection, giving you a better chance to win big.

Odds boosts are highly valuable because they allow you to receive much better odds on a line than you previously received, giving you more value for your bets. So if you’re looking to increase your potential profits when betting, be sure to keep an eye out for odds boost offers from your preferred betting sites.

Betting with March Madness Bracket Contests

You may have found a site that offers a bracket challenge such as ESPN, Yahoo, or CBS. These bracket challenges are different than betting with sportsbooks. A March Madness sportsbook will have individual game betting lines. You can bet who will win, how many points will be scored, what team scores the first basket, and more. It’s more than picking a team to advance.

Many March Madness bracket challenges are usually free to enter. On a sportsbook, you will have to bet your own money or use March Madness bonus bets available. There are sometimes betting opportunities when filling out a bracket but it’s different. You will most likely not find a traditional NCAA Tournament bracket on a sportsbook.
