The best real money March Madness betting websites

All self-respecting online sportsbooks will have odds for March Madness, but it’s a question of which one is right for your needs. So here are five of the best real money online sportsbooks who can give you a superior way to bet on college basketball:

BetMGM - Trusted site for college basketball betting

BetMGM Sportsbook: Pros & Cons

• Legal in dozens of US states
• Generous welcome bonus
• Great odds and odds boosts
• Live streaming available

• FAQ slightly complicated

Visit BetMGM

This industry heavyweight can always be counted on to serve up some awesome promos. You won't find one much larger than the current BetMGM welcome offer that will refund your first bet, if it loses, in bonus bets up to $1,500 - perfect for backing those inconsistent teams like Auburn Tigers.

Elsewhere you'll find lots of odds boosts, plenty of basketball betting lines, and a trusted range of payment options. You can bet at BetMGM from these states: Arizona, Colorado, District of Columbia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Mississippi, New Jersey, Nevada, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Wyoming.

Caesars - Get ten 100% profit boosts here

Pros and cons of Caesars Sportsbook

• Superb live betting coverage
• Great coverage for US and global sports
• High-value welcome bonus worth up to $1,000
• High-quality mobile app for Android and iOS

• Limited promotions for existing customers

Visit Caesars

All college basketball fans will like what they find at Caesars. Not only does this brand have lots of daily odds boosts and one of the best rewards programs in the business, but it also has a welcome offer that will give you 10 100% profit boosts just for making a $1 qualifying bet. Perfect for making the ultimate start on those first and second rounds of this year's tournament.

Here is the full list of Caesars’ legal states: Arizona, Colorado, District of Columbia, Indiana, Illinois, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, North Carolina, New Jersey, New York, Nevada, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Wyoming.

bet365 - Choose your perfect College Basketball promo here

Bet365: Pros & Cons

• Generous welcome offer
• Dedicated mobile apps for Android and iOS
• Live betting and streaming
• Diverse range of sports and betting markets

• No VIP or loyalty program

Visit Bet365

This is definitely the rising star of the US betting scene and bet365 will give you a choice of two welcome offers to make a decent start with your CBB bets. If you're backing a favorite like Duke Blue Devils, the $100 bonus bets could be a good deal. However, if you're willing to risk it on a relative outsider like the Louisville Cardinals, then the welcome offer that gives you a $1,000 first bet safety net could make more sense.

Just note that bet365 is only legal in Arizona, Colorado, Indiana, Iowa, Kentucky, Louisiana, New Jersey, North Carolina, Ohio, Pennsylvania, and Virginia.

FanDuel - Heavyweight online sportsbook with top CBB odds

Pros and cons of FanDuel sportsbook

• Superb welcome bonus
• Modern and stylish FanDuel betting app
• Available in 37 different states
• Fantastic futures bets

• The welcome bonus isn’t guaranteed

Visit FanDuel Sportsbook

Everyone knows that FanDuel is one of the biggest names in sports betting and so it's definitely worth checking out for this year's tournament. You can sign up here and enjoy a huge range of betting lines and nothing but quality odds too.

The best thing is that FanDuel's latest welcome offer will give you $200 in bonus bets if you bet $5. Just note that this first bet has to win, so it might not be suitable if you're betting on someone like the USC Trojans.

FanDuel is legal in most states where sports betting is, and you can bet at the sportsbook from Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Vermont, Virginia, Washington DC, West Virginia, and Wyoming.

DraftKings - So many player prop bets here

DraftKings: Pros & Cons

• Famous US-based brand
• Available in 26 states
• Bonus bet welcome offer
• Great odds
• User-friendly app

• Low bet limits for odds boosts

Visit DraftKings

Another massive online sportsbook and DraftKings is probably the place to go if you are looking for the largest amount of player prop bets. DraftKings can also be counted on to serve up some seriously generous promos. For example, signing up here and making a $5 bet will get you $150 in bonus bets - win or lose.

Once again, this sportsbook is widely available, meaning that you can use it for College Basketball betting from the states of Arizona, Colorado, Connecticut, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee, Vermont, Virginia, West Virginia, and Wyoming.

Top social sportsbooks for March Madness betting

Social betting sites will give you just as much fun when betting on March Madness as their real money counterparts. This is because they work in the same way only that you make your predictions with virtual currencies rather than cash. Don’t believe us? Check out the following five social sportsbooks and you’ll quickly see what we mean:

SportsMillions - Check out these unique Blitz’ems

SportsMillions: Pros & Cons

• No purchase necessary
• DFS and casino game options
• Ongoing bonuses and promotions
• Redemption possible with Sweepstakes Coins

• Not legal in all states

This is a social sportsbook that has created a storm thanks to its unique Blitz’em form of social betting. It can be used on basketball including CBB and is a statistic-based challenge involving making multiple predictions on the same game.

SportsMilllions will give you a solid welcome offer to start you off as you’ll get 33 Sweepstakes Coins and 7,000 Gold Coins. The best thing is that those Sweepstakes Coins can potentially be redeemed for cash prizes and gift cards. Just note that this social sportsbook is not available in the states of Alabama, Delaware, Idaho, Louisiana, Michigan, Montana, Nevada and Washington.

Fliff - Market-leading social sportsbook

Fliff: Pros & Cons

• Huge new customer offer
• Responsive support team
• Impressive mobile accessibility
• Range of ongoing perks

• Limited payment methods

Visit Fliff

Most people will already know that Fliff is one of the biggest social sportsbooks in the land and it is a great choice for making your predictions about College Basketball. You can sign up here from all states apart from Washington and enjoy the full range of betting lines for each game.

Just note that there is no real money gambling here but that you use virtual currencies called Fliff Coins and Fliff Cash instead. The Fliff Cash can potentially be redeemed for cash prizes, although it’s worth noting that these sweepstakes aren’t open to customers in Hawaii, Idaho, Nevada, or Tennessee.

Legendz - So many ways to enjoy CBB social betting

Legendz: Pros & Cons

• Generous welcome offer
• Redeemable cash prizes
• Quality slots and table games
• Massive online sportsbook

• Lacking a mobile app

Visit Legendz Casino

This social sportsbook has a great reputation for serving up a massive amount of social betting lines for each sporting event. You’ll get 90 lines for a standard NBA game and so it’s likely that the same will apply to any game in College Basketball.

You can get started here with a first purchase bonus that gives you 10% extra in terms of 500 Gold Coins and you also get three Sweepstakes Coins for free. While Legendz is available in most states, you cannot sign up here from the states of Michigan, Montana, Nebraska, North Dakota, Ohio, Idaho, and Washington.

Kickr - Impressive range of social betting lines

Kickr: Pros & Cons

• Social casino and sports offerings
• Numerous promotional offers
• Legit in 46 US states
• 15 gift card redemption options

• Limited number of games

Visit Kickr

This is a relatively new social sportsbook that is well worth checking out for making your College BB predictions. You’ll get to enjoy spreads, props, moneylines, totals, points range and even parlays here, and the whole thing can be done for free with the Bucks and Bits virtual currencies.

You get four free Bucks for signing up that can potentially be redeemed for prizes, and you’ll also receive 150,000 Bits to play for fun. Just note that this social sportsbook is only available in the states of Alabama, Georgia, Hawaii, Idaho, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Mississippi, Montana, Nevada, Ohio, South Carolina, and Washington.

Thrillzz - Yet another quality social sportsbook

Thrillzz: Pros & Cons

• Exclusive social sportsbook
• Highly-rated mobile app
• Email and phone support channels
• Welcome bonus of 3,000 Thrillzz Coins and 3 Thrillzz Sweeps

• Only available on mobile

Visit Thrillzz

Thrillzz was only launched in 2024 but it’s quickly become a real favorite for social betting on college basketball. Much of this is down to the fact that you can enjoy making your predictions on moneylines, points spreads and plenty of player props too.

Signing up will get you a 100% purchase match bonus up to $25 in Coins and you’ll also get $3 more Coins for free. There is also a sweepstakes mechanism that allows you to redeem any won Tickets for cash prizes. You can sign up to Thrillzz from all states apart from Alabama, Georgia, Idaho, Indiana, Iowa, Kentucky, Louisiana, Michigan, Minnesota, Mississippi, Nevada, Ohio, South Carolina and Washington.
