Top Betting Sites for march madness

Buzzer beaters. Cinderella stories. Cutting down the nets. March Madness brings a ton of excitement for sports fans and sports bettors. When wagering on March Madness, it’s helpful to have multiple sportsbooks to choose from. After all, your favorite No. 12 seed’s point spread might be +5 at one sportsbook and +5.5 at another. By shopping around and getting the best number on each bet, you’ll be more likely to win in the long run. BetMGM, FanDuel, Bet365, and Caesars, TonyBet, Sports Interaction, and Bet99 are some of the most trusted legal sportsbooks for March Madness betting, but each offer a slightly different experience. Keep reading to see what I like about each of these sportsbooks during the Big Dance.

FanDuel

FanDuel is a popular option for March Madness bettors and it’s easy to see why. As one of the most respected and recognizable names in the industry, FanDuel doesn’t disappoint with unique prop offerings, same-game parlays, and everything in between. If you ask around, you’ll find that FanDuel is known for great customer service, fast payouts, generous promotions, and generous profit boosts.

Strengths

Free March Madness bracket competition with prizes
Wide selection of player props (Assists, rebounds, points, etc.) in jurisdictions that allow it
Non-traditional prop markets like “Method of First Basket” and “Exact Score”
Alternate totals and point spreads for first-half lines

Weaknesses

Lacking easy-to-find data and statistics to aid in decision-making
Limited women’s basketball selection before March
Futures market prior to March doesn’t always feature odds for smaller conferences like the Summit League or Patriot League

Odds to be the #1 Seed

Image
FanDuel’s live betting platform allows live same-game parlays. So, if you sense a momentum shift, you could wager on the hot team winning the game with the total going over in a 2-leg parlay. (You can surely get more creative than that though).
Image
FanDuel is one of the rare sportsbooks to offer reverse teasers on March Madness games. For instance, instead of adding four points on a point spread in exchange for worse odds, you can subtract four points on a spread in exchange for better odds on your teaser.
Image
FanDuel’s Futures market features bets you won’t easily find at other sportsbooks before March. For instance, in addition to wagering on a team to win the National Championship, you can also get odds for them to make the Final Four or the field of 68.

BetMGM

Like the UConn Huskies, BetMGM has a ton of fans and can be consistently relied upon in March. BetMGM’s sportsbook is a great option for first-time bettors or those who have been betting since Christian Laettner ripped Kentucky’s heart out. As you’ve likely noticed when visiting MGM properties, BetMGM takes pride in its customer service. With fast payouts and surprise incentives and contests, BetMGM is a trusted choice for March Madness sports betting.

Strengths

Live betting features quick access to data and play-by-play for each March Madness contest
Solid selection of player props (points, rebounds, assists, etc.) in jurisdictions that allow it
Separate “SGP” tab for easily creating Same Game Parlays which can include player props in some jurisdictions
Teaser bets options

Weaknesses

App can take a bit to get used to
Limited stats/data available for pre-game wagers
Limited NCAA women’s futures props before March

Image
The odds of you picking a perfect March Madness bracket aren’t very good, but if you can, BetMGM will pay you handsomely. Last season, the sportsbook’s free-to-play Perfect Bracket Challenge offered $10 million.
Image
The “Edit My Bet” function allows you to increase your stake, swap out parlay selections, etc. on certain bets after you’ve placed the wager. If your wager is unsettled and has a “cash out” option, then you’re able to edit it. This can be especially helpful if you’ve changed your mind about a March Madness wager because of an injury.
Image
If you like to build teasers with your March Madness bets, then consider BetMGM, because they allow teasers of up to 14 points, while many other sportsbooks won’t go past 10 points.

Caesars Sportsbook

Caesars Sportsbook can do it all, much like Alabama Forward John Broome. Caesars offers March Madness bettors a deep selection of betting options during the Big Dance. Caesars delivers quick payouts, polite customer service, and all the bells and whistles you expect from a major sportsbook. Caesars app is very intuitive and offers unique features like a sliding bar to adjust odds.

Strengths

Wide selection of player props (rebounds, assists, etc.) in jurisdictions that allow it
Left-to-right slider function simplifies alternate line betting
Robust live-betting menu with winning margin bets, and alternate totals and point spreads
Live betting features play-by-play function recapping the game’s history to inform your wager

Weaknesses

Moneyline may not be available for games with very high point spreads
Doesn’t consistently offer women’s NCAA lines throughout the year
Alternate team totals typically unavailable before tip-off

Image
While shopping around for different March Madness sides and totals, you’ll notice that Caesars’ lines are often off by a half-point and that makes Caesars a valuable option in your sportsbook portfolio.
Image
Caesars provides pre-made parlay options with clever titles like “Late Night Hoops” for evening games. The odds for these bets are posted prominently on your screen and the bet is a click away, but it’s wise to do your own research too!
Image
Live betting during March Madness is simple with Caesars and I especially like the unique slider function that can be used to set alternate point spreads and totals while a game is happening.

bet365

March Madness bettors will appreciate that bet365 focused on creating a website and app easier to navigate compared to others. For instance, bet365 has a separate “teaser card” tab which automatically adjusts the lines for every single game on the card when you adjust the size of the teaser. Prior to the Big Dance, bet365 organizes games by conference, making it easier to find your games. With fair odds, great customer service and quick payouts, bet365 is a winner.

Strengths

3D basketball court to follow live bets is one of the industry’s best-looking graphics
Robust selection of player props (rebounds, assists, 3PM, etc.) in certain jurisdictions
Games are neatly organized by conference, making it easier to find your game
Stray lines that often differ from other sportsbooks

Weaknesses

No live play-by-play log while live betting
Lacking women’s college basketball lines throughout the season
NCAA Basketball Futures options before March Madness

Futures Boosts

Alt Spreads

Image
Moneylines are routinely offered for March Madness games with really high point spreads at bet365 even though other sportsbook remove that option when spreads get around the 20-point mark
Image
Alternate team totals can be found before March Madness games tip-off at bet365, while some sportsbooks only offer alternate full-game totals
Image
If you live in an area that allows player props for college basketball games, bet365 has one of the better selections. Happy hunting!

sports Interaction

Sports Interaction is a nice option for March Madness bettors with all the bells and whistles bettors expect from a trusted sportsbook. Sports Interaction consistently provides solid customer service and typically smooth payouts if you happen to get hot in March like the UConn Huskies did last season.

Strengths

Sports Interaction allows NCAA Basketball teaser bets up to 14 points, while most books won’t go past 10-point teasers
Deep futures prop markets with unique offerings not found at other sportsbooks
Detailed play-by-play history while live betting

Weaknesses

Image
If you enjoy betting alt spreads and totals, Sports Interaction is a great choice. While some sportsbooks offer only three or four alternate numbers to choose from, Sports Interaction has a long list of alt lines and the further you get from the actual spread or total, the juicier the odds.
Image
“Piñata Picks” is a unique angle of betting found only at Sports Interaction. They use random number generator software to assign odds to a specific bet. For instance, in the best-case scenario, you could get nice longshot odds on a team like Duke to win the whole tournament.
Image
In addition to the standard college basketball futures markets (National Championship odds, etc.), Sports Interaction offers some conference vs. conference props. For instance, “Which conference will have more wins vs. the other, the Big East or the Big 12?”

tonyBet

If you’re a meat-and-potatoes March Madness bettor, then TonyBet is worth a look. With TonyBet, you’ll get everything you’ve come to expect from a respected sportsbook (good customer service, etc.) without the fancy additions like live streaming. TonyBet is a solid choice for March Madness bettors, just be aware that they often have higher vigorish on their lines compared to other books.

Strengths

Solid selection of standard March Madness l live bets
Live running clock for live bets to ensure your game feed isn’t behind
Some alternate total lines available before tip-off
Odds boosts on parlays, with odds increasing the more legs you add

Weaknesses

TonyBet commonly has extra vigorish compared to other sportsbooks
No Women’s NCAA games during the regular season
Limited live betting for “micro bets.” For example, betting on the result of the next possession
Payouts can take longer than other sportsbooks

Image
TonyBet offers a decent selection of live bets for March Madness including “Race to 60 points” and odds with the spread and total parlayed together
Image
The “Analytics” tab shows a trend and a bet associated with it. For instance, “Holy Cross has avoided overtime in each of their last 15 games” with a betting option on “No Overtime” under the trend.
Image
TonyBet also offers Over-Exact-Under odds for games, which is like the traditional over/under market with a third option for if the game lands exactly on that number. This is a fun option if you like longshot odds on the exact price, but be careful, it’s giving me green zero roulette vibes.

bET99

Bet99 is a March Madness live bettor’s playground. With “FlashBets,” you’re able to wager on the smallest detail of each college basketball game. During the season, Bet99 also features a large selection of games (men’s and women’s) and betting options before games tip-off. Customers often report strong customer support and fast payouts from Bet99 as well.

Strengths

Unique in-game options with “FlashBets”
Wide selection of player props in jurisdictions that allow it
Convenient pre-made two-leg parlays to consider while pondering wagers
Large selection for women’s NCAA Basketball Tournament too

Weaknesses

If you’ll be betting March Madness player props, then Bet99 is an easy choice. Bet99 has lines for rebounds, points, assists, and 3-pointers made.
Image
Bet99’s “FlashBets” offer bettors the ability to wager on what will happen next during any March Madness game. For example, “Which team will make the next basket” or if the next bucket will be a 2-pointer or a 3-point shot.

While live betting throughout March Madness, Bet99 offers relevant stats to consider before making your wager. For instance, you can quickly see how many offensive and defensive boards each team has grabbed and those numbers are updated live.

how we rank top march madness betting sites

Our sportsbook reviews are built on thorough, hands-on testing by our industry experts who prioritize what bettors care about most—security, competitive odds, fast payouts, and a smooth user experience. We break these down into a series of Trust Factors that have been FinCertified, by receiving the Odds Shark fin seal of approval from our expert team.

Our structured evaluation process ensures that only the best and safest betting sites make the cut. Each sportsbook undergoes rigorous testing, from signing up and collecting bonuses to placing bets and withdrawing funds. (Nobody said our job isn't fun!)

Odds Shark FinCertified Trust Factors

Image
User Experience: We are looking for sportsbooks that make the betting process seamless. If we have a hunch on a game, we want the odds for that game at our fingertips. Easy-to-access Bet Slips, intuitive Parlay Features, and a detailed Betting History, are just a few of the user experience criteria our experts require from the best betting sites for the March Madness.
Image
Bonus Availability: We look for sportsbooks that offer real value in their customer deals. Not some snazzy marketing lingo, but real dollars available for you to collect. From killer welcome bonuses and promo codes with realistic conditions, to lucrative everyday customer offers, Bet Boosts, rebates, and VIP programs. Sportsbooks must offer something we can understand and can reasonably collect upon, or we won't recommend them to you.
Image
Payment Process: We all want to be able to fully realize our winnings and take our money home. Too many sportsbooks make it so difficult to withdraw your funds, that you are forced to bet again, seemingly indefinitely. At Odds Shark, we only recommend betting sites that our experts are comfortable holding their own bankroll. The best March Madness betting sites offer a variety of reliable deposit methods with reasonable payout speeds, so that you aren't the friend that can't buy dinner because "all my money is in my betting account".
Image
Sport Odds Variety: We champion sites that provide extensive odds across a huge range of global sports. Sportsbooks must prove they are ready to promote big events properly. It isn't going to matter whether a betting site has Korean Baseball odds, if they can't get the Super Bowl right, but we know the way those popular betting markets are juiced. Every now and then, our Odds Shark handicappers have a gut-feeling on a European Handball match at 5am on a Wednesday. We want a sportsbook that lets us ride that out with them.
Image
Safety & Security: Odds Shark takes player safety very seriously. We only recommend betting sites that match our high degree of safety and security standards. That means a site must operate 256-bit SSL or TLS encryption as standard. They also need to provide fair, transparent Terms & Conditions for all players.
