If you are on the hunt for the next best March Madness betting promo, then I would like to think that you already have a decent understanding of what March Madness is and how it works. However, for those who are new to the NCAAB’s biggest tournament and simply looking to mix things up, let me provide you with a quick breakdown.
March Madness is a 68-team NCAAB tournament that follows a single-elimination model. In other words, each team has one chance against their opponent to move on to the next round. This continues until one team is eventually crowned the winner.
This year, things kick off on Sunday, March 16th, when we learn more about the selections. From here, the “first four” (the lowest-seeded teams) will face off to see who joins the main competition. Then, you will find the tournament runs on the following schedule, eventually reaching its climax on April 7th at the Alamodome in San Antonio, Texas.
It would be fair to suggest that online betting laws are pretty complex throughout the US. So, before you think about getting your hands on a March Madness betting promo, it could be worth considering how you will be betting on March Madness this year.
In 38 US states, you’ll find some of the best real-money sportsbooks are legal and open to you. This provides you with the chance to deposit, unlock, and play through real-money betting promos across a range of March Madness markets. But what about the rest of you?
Well, you’ll also find that social sportsbooks now operate under the sweepstakes umbrella. These social betting sites allow you to unlock Gold Coins and Sweeps Coins to socially bet on March Madness in two separate betting “modes”.
Gold Coins are for entertainment only, allowing you to enjoy the full social betting experience with fun as your focus. Sweeps Coins, however, will enable you to enter a promotional style of social betting. In turn, you will find that any additional Sweeps Coins won through social bets have the potential to be played through and redeemed for real prizes. Of course, the terms surrounding this will vary based on your chosen site.
The other good news about social sportsbooks is that they are considered legal in most US states, meaning even those with real-money sports betting opportunities could opt to join a social site instead. Not to mention that social sportsbooks are entirely free to use, meaning you can pick up March Madness betting promos without ever spending a dime.

Although not the only thing you should be looking out for when joining a March Madness betting site, there is no doubt that bonuses and promotions will play a huge role. With this in mind, I’ve taken the time to provide you with a quick look at the most common offers you’ll find at real money and social sports betting sites.
| March Madness Betting Promo | Real Money Betting Bonus | Social Sports Promo |
|---|---|---|
| Deposit match | ✅ | ✖️ |
| No deposit bonus | ✅ | ✖️ |
| First bet offers | ✅ | ✖️ |
| Odds boost | ✅ | ✅ |
| Predictors | ✅ | ✅ |
| Refer a friend | ✅ | ✅ |
| Daily login | ✖️ | ✅ |
| Social media giveaways | ✖️ | ✅ |
| Alternative Method of Entry (AMoE) | ✖️ | ✅ |
Now that you know a little bit more about the types of March Madness betting promos you are likely to stumble across, let’s make sure that you understand the terms attached to them.
Regardless of whether you’re betting with real money or virtual tokens, promotional codes may be required to initially get your hands on the latest March Madness betting promos. These codes must be entered exactly as they are shown. If not, you could find that you miss out on the opportunity.
You won’t find wagering requirements attached to your Gold Coins. However, you may find that you need to use your Sweeps Coins at least once within a set timeframe at the top social sportsbooks. At real-money gambling sites, you’ll almost certainly come across wagering requirements. This can vary; however, it usually requires you to wager the deposit, bonus, or combined value between 1 and 15 times.
The expiration dates will link well with the wagering requirements. As March Madness runs for a few short (but chaotic) weeks, you won’t find any crazy 45 or 60-day expiry dates attached. That said, March Madness betting promos with a longer expiry date will give you more time to meet the attached wagering requirements. Fortunately, all of this is covered in my latest reviews.
As March Madness only runs for a few weeks, you’ll find that bonuses can be used on a very short pool of matches. Obviously, as the tournament continues, you’ll see fewer fixtures available to you, so be sure to check the fine print before unlocking – I’d hate for you to lose out because an eligible team had been knocked out.
A minimum odds requirement is also quite common to find within the terms and conditions of a real-money sports betting promo. This can vary from bonus to bonus but will only allow bets to contribute that are placed on odds greater than the determined value.
Although primarily found at real-money gambling sites, you may see certain prize pools are capped at social sportsbooks, too. As you would suspect, this refers to the maximum amount you can win by making use of a specific bonus or entering a March Madness predictor game.
Finally, I think it is worth considering what comes next for you, too. Sure, March Madness is packed with exciting promos, but I imagine many of you won’t stop once the tournament ends. With this in mind, I’d take some time to get familiar with the ongoing promotions and consider the chances of picking up perks through a dedicated rewards program.
Now for the bit you’ve been waiting for. I’ve been busy reviewing the best March Madness betting promos available and have decided that these five real-money sports betting sites deserve to have the spotlight shined on them. Just bear in mind that the bonuses mentioned in these mini-reviews are examples only and may vary based on your current location.
Let me begin with a closer look at the ever-popular BetMGM. As a new user, you will soon be able to make the most of a first bet offer of up to $1,500. However, you will also find College Basketball odds boosts and a free-to-play game predictor along the way. So if you've been following NCAA Basketball news, this promo might be of interest to you.
Once you’ve unlocked your welcome bonus, you’ll want to head on over to the ‘basketball’ section. Here, you will then find a small tab in the header that allows you to open up ‘college’ markets. Instantly, you’ll be met with spreads, totals, and moneylines; however, a quick click on the ‘All Wagers’ tab opens the doors to a range of alternatives. Not to mention that in-play betting opportunities are also available.
Caesars is renowned for mixing things up, offering fans from different states the chance to benefit from separate bonuses. As an example, though, you may find that you can bet $1 on College Basketball markets and receive up to $150 in bonus bets to use across the site, or you could bet $1 and receive double winnings on your next ten wagers.
Regardless of the CBB betting promo you select, you’ll always be backed by competitive odds. You’ll also find that the app and desktop site are easy to navigate, bet-building is a breeze, and each wager will contribute towards your Caesars Rewards. In time, you could find that your CBB stakes have unlocked an overnight stay or expensive dinner out.
Next, it is time to take a look at bet365. Again, you’ll have a choice between your welcome bonus; however, this will be limited to a $1,000 first bet offer or the chance to bet $5 and get $150 in bonus bets.
Unsurprisingly, you’ll find College Basketball is trending on the left-hand side of your screen. A quick click is all it takes to open up eligible markets. Spreads, moneylines, and totals are all backed by competitive odds, and in-play opportunities are updated regularly. Plus, I was a big fan of the boosted odds, offering enhanced odds on a selection of pre-made four-part parlays.
Although often dubbed as the home of daily fantasy sports, FanDuel more than holds its own as a sportsbook. In fact, as a new user, you can pick up a pretty impressive welcome bonus to help get your experience off to a flying start – simply bet $5 and get $200 in bonus bets if it wins.
Alongside a top welcome bonus, you’ll find a number of boosted odds and seasonal promotions running during the CBB campaign. You can also bolster your betting experience here by making use of the research tools and player stats before heading to the lobby and placing your spreads, moneylines, totals, props, or futures.
The final spot has to go to Draftkings. Here, you can get signed up within minutes before making the most of a welcome bonus, offering you the chance to make a $5 bet and get $150 in bonus bets. From here, I soon spotted College Basketball parlay boosts, a referral program, and Dynasty rewards to ensure you add to your bonus balance throughout.
CBB betting promos aside, I also found one of the most complete sports betting lobbies in December. Although busy for some, you’ll find headers focused on game lines, props, quick hits, combos, moneylines, and more. Not to mention that updated in-play opportunities are available, too. I liked how easy it was to build your bets, and you could test the waters from as little as $0.10.
If real-money betting sites are out of the question for you (or you just like the idea of social betting sites), you’ll definitely want to check out these fantastic social sportsbooks. As you’ll soon see, all come with great perks, including a clear focus on this year.
Sports Millions kicks things off with a unique take on social betting that introduces a daily fantasy element. Here, you will be able to register within minutes, add 1,000 Gold Coins and 3 free Sweeps Coins to your account, and soon make your way over to the lobby.
Here, you will soon find Blitz ‘ems – a hybrid social betting and DFS contest that runs exclusively at Sports Millions. The idea is that you’ll enter your chosen College Basketball ‘contest’, spin a prize wheel, and spin another wheel to determine your picks. These picks are auto-assigned, making the process nice and quick. However, to win, you’ll need all selections to land. Along the way, you’ll find that you can keep things topped up with an impressive daily login bonus, social media giveaways, and an AMoE.
Fliff is a bit of a curveball as they don’t currently allow you to pick up a free-to-release new customer offer straight from the off. That said, you can make the most of a daily login bonus and the AMoE to ensure that you get enough Fliff Coins and Fliff Cash to really enjoy College Basketball. Of course, if you don’t mind splashing the cash, Fliff does have a number of first-time purchase promo options, ranging from $9.99 - $99.
So far as social betting is concerned, you’ll notice that you can soon head on over to the College Basketball section of the app. Here, you can filter through all upcoming fixtures, building your predictions with a single click. I found around 10-15 markets per fixture, ranging from moneylines to alternative totals. Should you opt to bet with Fliff Cash, remember that any winnings can be played through and later redeemed for prizes. You’ll just need 50 redeemable Fliff Cash in your account to get the ball rolling.
Next up, it is time to talk a bit more about Legendz. This is a social casino and sportsbook hybrid that allows you to get started with a healthy 500 Gold Coins and 3 free Sweeps Coins. From here, you’ll see that a quick click on ‘sports’ is all it takes to discover available CBB markets.
Once you find yourself in the social betting lobby, a world of social betting opportunities awaits. You’ll find that Legendz extends far beyond standard moneylines and spreads, offering chances to bet on totals, props, and futures with fun or promotional betting as the focus. Plus, I really liked that you could personalize the sportsbook, highlighting your favorite sports, teams, and players.
Kickr is another hybrid platform that allows you to enjoy casino-style games and social betting under one roof. To get you started, you can click on the links on this page, work through the registration form, and soon unlock 150,000 Bucks and 4 Bits. I also found that a daily login, drip, and referral program helps to keep your Bucks and Bits topped up during the tournament.
Speaking of College Basketball, you’ll find that this is heavily covered over at Kickr. You can toggle over to the sports section, click on basketball, and soon find social betting markets throughout March and April. Just bear in mind that a comparatively higher prize redemption limit (200 redeemable Bits) can be expected for those betting with Bits in a promotional manner.
Thrillzz is an app-only social betting and prediction platform that offers great coverage of College Basketball. To join, you’ll need to download the app, share some personal details, and verify your account before you can get your hands on 3,000 Thrillzz Coins and 3 Thrillzz Sweeps.
Once locked and loaded, you can make your way over to the lobby. The app is simple to navigate, providing you with a scrollable main page and key links in the header and footer of the screen. Social bets can be placed within a couple of clicks, ongoing rewards keep your virtual tokens topped up, and the social ‘Squads’ feature helps you link up with friends to create some top predictions.
That should have just about covered everything you need to know about college basketball betting promos in 2025. Now, all that is left to suggest is checking out my latest reviews on the best March Madness betting bonuses available.
As you can see, real-money sports bettors should consider starting with BetMGM, Caesars, bet365, Fanduel, and DraftKings, while social bettors should take time to check out Sports Millions, Fliff, Legendz, Kickr, and Thrillz. All of these sites provide excellent coverage of College Basketball, offer competitive promotions, and allow you to really immerse yourself in the action. Just remember to set your limits early, check out the small print, and don’t forget to consider what promotions await once the mayhem of the tournament passes you by.
No. Due to the very nature of social sportsbooks, you won’t win money using a March Madness betting promo. That said, you can use your bonus Sweeps Coins to bet on social markets with a promotional element involved. Provided any winnings are played through and meet the requirements of your chosen site, you’ll find that you can redeem prizes.
It all depends on the bonus that you decide to unlock. Generally, if the betting bonus has been targeted at March Madness, it will need to be used during the tournament on specific matches. However, if looking at a sign-up bonus, you will find that it can be used on a number of additional sports.
It all depends on your approach. Social betting fans will want to find a simple but effective bonus that fills your Gold Coins and free Sweeps Coins points with plenty of playing time, while real-money sports bettors will wish to find offers with competitive wagering requirements and inclusive limits.
