2. BetMGM Sportsbook

BetMGM Sportsbook

BetMGM Sportsbook gained a reputation for awesome offers during the last NCAA basketball tournament, making it a top betting site. The highlight of BetMGM’s promotions during March Madness was a $10 million March Madness Bracket Challenge. The contest was free to new and existing customers and had a $10 million grand prize for a perfect bracket. No one won the big one, but BetMGM still paid out $100,000 to the person who got the most correct picks.

Expect BetMGM to run similar promos for the 2024 NCAA men’s basketball tournament.

  • Player to make the first 3-pointer of the game
  • Team to make the first 3-pointer of the game

Earlier in the tournament, FanDuel offered up prop betting on teams to win a region, as well as conferences and seeds.

DraftKings Sportsbook has some of the best NCAA tournament pools with big-money payouts annually. This past March, DK ran a Championship Series Millionaire Bracket with $1 million to the first-place winner. The entry fee was $100, and it had a total prize pool of $2 million.

DraftKings also ran several free entry pools during March Madness, and all signs point to DK doing so again for the 2024 Big Dance.

6. Bet365 Sportsbook

bet365 Sportsbook logo

Bet365 Sportsbook is the new kid on the block in many states. The book opened with a bang this past March, offering users the chance to enter a perfect bracket challenge that would have paid out $10 million. It’s pretty much mathematically impossible to get a perfect bracket, but Bet365 still had big money payouts to its top performer. The winner received $100,000.

Betway Sports

Betway Sportsbook has an easy-to-use interface where you can quickly find almost any college basketball line. During March Madness 2024, expect Betway to have plenty of “enhanced odds,” which they call “Betway Boosts.”

Betway also has one of the top “cash out” options around. It allows the bettor to take out his or her winnings early or to cut their losses before the end of a game. The amount you can cash out depends on how much you initially bet and the live odds of the event you bet on.

How we rank the best March Madness betting sites & Apps

TheLines always encourages college basketball bettors to shop around for the best odds. You can find all sorts of odds comparison tools on our website, including college basketball odds for every daily game and NCAA National Title odds.

Not all sportsbooks are created equally, and our rankings of sportsbooks go above the best college hoops lines. TheLines staff ranks the books above in the order they are placed by the following criteria:

  • The Best March Madness Odds
  • Fastest Payout Speeds
  • Best Promos
  • Deposit Options
  • User Interface
  • Customer Service Access

College basketball betting is approved in every state that offers legal sports betting, but the specific rules vary. North Carolina sports betting has launched just in time for March Madness. Kentucky sportsbooks, another new market, allows legal wagers on the Kentucky Wildcats and Louisville Cardinals without leaving the state. More established markets like New Jersey and New York do not allow wagering on in-state teams. Arizona, Colorado, Tennessee, and Pennsylvania do not allow college prop bets on players.

How to bet on March Madness

Pick a college basketball betting site

The majority of legal sports betting states have several March Madness betting sites to choose between. Use the above tables to see which ones are available in your market. Then it comes down to deciding which one you want to go with. Welcome offers, college basketball promos, and betting menus are factors to consider before deciding. The upside is there is no rule against creating multiple sportsbook accounts simultaneously.

Get your bonus and deposit

Once you’ve selected a sportsbook, you’ll need to register for an account. There will be a spot to enter one of the above promo codes so you can get your welcome bonus. Others do not require a code to receive Bonus Bets or offers. You will also need to provide your name, email, address, date of birth, and the last four of your SSN for verification purposes. Once you register and deposit funds into your sportsbook account, the NCAA Tournament betting can begin. Many March Madness betting sites have a minimum deposit of $10.

Place an NCAA basketball bet

There will be plenty of markets to choose between, such as a futures bet on the UConn Huskies repeating as the 2024 NCAA Tournament champions or taking the moneyline on a 12-seed to upset a 5-seed in the first round. Others might like taking the Kentucky Wildcats to make the Final Four. The bottom line is, including the First Four, the NCAA Tournament consists of 67 games over three weeks, so there will be no shortage of betting options.

March Madness bet types

Point spread

Betting the point spread on a March Madness game is one of the most common ways to wager. For example, Arizona is a 2-seed and is playing Murray State, a 15-seed. High seeds like Arizona will be heavily favored, usually in the double digits. 

For this example, Arizona is a -16 favorite over Murray State (+16). If you bet Murray State to cover the point spread, you would need them to either win outright or lose by 15 points or less. If Murray State lost by exactly 16 points, it would be a push, and the amount of money you bet would be refunded.

Let’s say you bet Arizona to cover the big 16-point spread. You would need the Wildcats to win the game by 17 points or more to win the bet.


A moneyline bet on a March Madness game is also extremely common. There are so many college basketball upsets during the tournament that betting the moneyline on an underdog can be quite lucrative – even if you bet a small amount.

An extreme example is from this past year’s NCAA tournament. Sixteen-seed Fairleigh Dickenson had +2000 moneyline odds to upset one-seeded Purdue. Fairleigh Dickinson pulled off the miracle, and those who had Fairleigh Dickinson winning tickets were in the money. A $10 bet on Fairleigh Dickinson to win would have garnered most bettors a $200 profit.


Totals markets, or over unders, are another common way to bet on NCAA basketball. Let’s use this past National Championship game as an example. The UConn versus San Diego State title game had a total of 132 points. 

The final score of the game was UConn 76, SDSU 59. That equated for a total score of 135 points, so Over bettors cashed.


Big-picture bettors love futures bets. Various futures bets are available during March Madness, most notably National Title odds. 

It is difficult to pin down the winner at the start of the Big Dance just because there are so many teams and major upsets. So more conservative college hoops bettors will entertain markets like “Odds to make the Sweet 16,” “Odds to make the Elite 8,” and “Odds to make the Final Four.”


Prop betting on March Madness can be tricky as states have different laws regarding betting on games played by student-athletes. Team props are more common as they don’t involve an individual. You will often see college basketball team props like “Over Under 3-pointers made by Kansas,” and “First basket made: Duke or North Carolina?”

Player props, like over under player totals, are not always available but be sure to check with your state and sportsbook rules before wagering. Popular player props, if they are available, will include markets like “Adama Sanogo Over Under 18.5 points” or “Cason Wallace Over Under 3.5 3-pointers made.”

Benefits Of Betting On March Madness Online

It’s important to make sure the March Madness betting site you’re using is legal and regulated. There are many illegal offshore sportsbooks operating in regulated markets that are not safe. Look for an RG logo on any legal March March Madness betting site. It means there are responsible gambling tools built into the platform. They will include setting deposit limits, cooling off periods, and reality check time limits. Adding your name to a temporary/permanent self-exclusion list is available as well at top March Madness betting sites. All betting sites recommended on TheLines are legal, safe, and regulated.

Having access to fast deposits and withdrawals are important when March Madness betting season rolls around. Many March Madness betting sites now offer Venmo betting, PayPal betting, and Apple Pay betting as banking options. These transactions can be completed in a quicker timespan versus ACH or cash at the casino cage.

Live Betting Options

Live betting markets are a big part of the NCAA Tournament betting experience. It can bring an added level of excitement, especially when a top seed like the Kansas Jayhawks or Duke Blue Devils is mounting a big comeback versus an underdog trying to pull off an upset. During the game, top online sportsbooks like the ones mentioned above will add their desired edge to the algorithm’s probability. New odds will be computed and offered to bettors. Scoring runs and lead changes are a couple of factors causing the moneyline or point spread odds to change several times during a game.

Bonuses and Promotions

Bonuses and promotions help give March Madness betting sites an edge over the retail sports betting experience at a land-based casino, racetrack, or stadium. You might enjoy an amazing viewing experience at your favorite Atlantic City and Pennsylvania sportsbook, but you will likely not receive Bonus Bets or promos such as odds boosts or profit boosts when walking up to the betting window or kiosk. Come NCAA Tournament time, the offers available to new and existing customers tend to be stronger.
