Today I’ll be jumping feet-first into the world of March Madness betting promos – and you’re coming with me. These offers can help you keep the action going when wagering on the most exciting college sports event of the year.
Here’s the thing, not every betting bonus is all that it’s cracked up to be. They look great in the ad but the T&Cs are packed with high wagering conditions, multiple restrictions and short time limits. However, I have found a few diamonds – so stick with me to find the best welcome betting offers for March Madness 2025.
What better way to enjoy the pinnacle of NCAA betting entertainment than by picking up a special offer? The good news is that each of

I’m not one to beat about the bush, so let’s get straight down to business of looking at those deals that players outside the US can get. I have tested out plenty of March Madness betting promos in my time, and while there are plenty of borderline scams to avoid, there are also buckets of good ones to be found.
As they say, the cream always rises to the top, and so here are the five bonuses that I believe are the
crème de la crème
for betting on March Madness in 2025:
| Betting site | Welcome bonus | Promo code |
| Stake.com | 200% up to $2,000 | GAMECHAMPIONS |
| BC.Game | 180% up to $20,000 | N/A |
| GG.Bet | 150% up to $150 | N/A |
| Vulkan.bet | 100% up to $500 | N/A |
| Bet365 | $100 in bet credits | N/A |
The site itself is excellent for NCAA game live streaming, and you don’t even need an active bet to watch. Here is my summary of the main pros and cons of Stake.com in relation to March Madness betting:
Pros & Cons
- Exclusive 200% deposit match offer
- Live streaming for March Madness
- Great live betting platform
- Competitive odds
What better way to start than with a GameChampions exclusive? If you register at Stake.com ahead of March Madness 2025, make sure to enter this promo code:
GAMECHAMPIONS.
This will unlock an exclusive welcome offer consisting of a 200% deposit match up to $2,000. For example, if you deposit $100, you will get $200 in bonus credits to wager on March Madness and other sports events.
BC.Game – 180% up to $20,000 for big-buck players
This is a colossal crypto betting site with some of the best odds around, still, it is not without its pitfalls. Here are the main advantages and disadvantages of betting on this platform this March Madness:
Pros & Cons
- 180% deposit match
- $30 min deposit bonus requirement
- Best value odds overall for March Madness
- 40+ sports betting markets
Of all the March Madness betting promos that I’ll cover in this article, this one has the highest deposit limit. Of course, this makes it ideal for all of you high rollers out there, but make sure that you don’t stretch your budget.
You can also claim this bonus with a relatively low first deposit of $30, so it is accessible to a whole range of players. As well as NCAA basketball and March Madness, BC.Game has betting markets on 40+ sports – more than almost any other site.
GG.Bet – 150% up to $150 regional bonus
To help with your bets, this sportsbook is packed with research tools, including stats and data sheets. On top of that, here is what you can expect on this betting site:
Pros & Cons
- Bonus on your first four deposits
- Crypto and fiat payments
- Basketball stats and data sheets
- Legal in many regions
- Slow payouts for some payment options
The numbers involved with this bonus might vary slightly depending on your currency and region. However, that doesn’t stop it from being among my top-rated March Madness betting promos for 2025.
Regardless of your location (provided GG.bet is legal where you are of course), you can claim a deposit match on your first four deposits. As a result, the bonuses can keep coming throughout the tournament – from the First Four up to the NCAA Championship game.
Vulkan.bet – 100% up to $500 first deposit match
In my experience, the user-friendly interface is the standout feature of Vulkan.bet, but that’s not all there is to this site, as you can see below:
Pros & Cons
- 100% deposit match up to $500
- User-friendly interface
- Good live betting feature
- MGA licensed
If you’re looking for a classic welcome offer that’s flexible and easy to understand, this is it. Just make your deposit, get your 100% match, and wager the bonus to withdraw your winnings – it’s that simple.
While it might not be the largest of the March Madness betting promos I’ve covered, the $500 maximum should be a high enough ceiling to suit most of you. At the other end, the
$10 minimum deposit requirement
makes it accessible for all of you casual bettors out there.
Bet365 – Up to $100 in bet credits
Pros & Cons
- Up to $100 un bet credits
- Available in many countries worldwide
- Odds boosts and other specials
- Top-rated site for basketball betting
- Bonus can differ greatly between regions
This colossal betting brand probably needs no introduction, and you can get up to $100 in bet credits as a new player. However, I should point out that the welcome offer here can differ substantially based on your country or region. You can check out our banners for an accurate offer in your region.
Regardless of where you are though, what I can assure you is that this is one of the best sites for basketball betting on the whole. As well as the welcome offer, you can expect to find additional March Madness betting promos here, including odds boosts and other specials.
As you will have seen above, March Madness betting promos come in a variety of different shapes and sizes. Some are better than others in general, while others match certain betting styles more than the rest.
To help you choose your ideal
betting bonus for March Madness
2025, here is an explanation of the most common bonus types and how they work. I have included existing customer promotions below as well as welcome offers.
These are one-off bet tokens that you can use as a single stake on a March Madness bet. Usually, the bonus bet value is not included in your returns, but wagering requirements tend to be low 1x to 5x or even zero on some sites.
This is like a bonus bet, with the only difference being that it is paid to you in equal value to your stake if your first March Madness bet loses.
Most of the deposit match March Madness betting promos that I’ve mentioned above will be paid to you in the form of bet credits. These differ from bonus bets as your bet credits can be used as multiple or single stakes. However, this is offset by the fact that wagering requirements are often higher.
More commonly for existing customers than newbies, cashback is a type of bonus that is calculated based on your net losses over a period of time. For instance, let’s say that you lost $100 during the Round of 32 part of March Madness, a sportsbook with a 20% cashback promotion would give you a 20% cash bonus back.
These are common promotions where the odds for certain markets are enhanced to a better price. For instance, it’s common for betting sites to enhance their
Elite 8 odds
on one or all four of the games.
While there are some trash bonuses out there, the five offers that I’ve covered in this article all have the potential to be gold. That being said, some of them might not be suited to your budget, level of experience, or style.
Before deciding which betting sites to register with and which bonus to claim, here are a few things that you should consider first:
- Budget
– First and foremost take a look at the minimum and maximum deposit and bet limits required for the bonus. If you’re working with a small bankroll, low minimum limits are better. However, the high rollers among you might be looking for a higher maximum, like the 180% up to $20,000 on offer at BC.Game.
- Experience level
– Some March Madness betting promos are more complex and harder to understand than others. My advice is to read the T&Cs, and if you don’t understand everything, then the bonus is perhaps just beyond your capabilities at this time.
- How often you bet
– If you tend to only bet once or twice throughout the March Madness tournament then a seven-day time limit or a one-off bonus will be fine for you. If you’re likely to go the whole hog with
NCAA March Madness bracket betting, then a 30-day bet credits deposit match will be better studied.
- The betting site
– Your bonus will last for around a week to a month maximum, and March Madness is over and done within three weeks. However, your online betting account is with you for the long haul. It’s therefore vitally important that you pick the right betting site, as well as the best welcome offer for you.
My top tips to help you get the most out of your
betting bonus for March Madness
Selecting your ideal bonus only marks the beginning of an exciting journey. The real fun begins once you’ve claimed your bonus, placed your bet, and the first game tips off.
However, you shouldn’t just slap your bonus bet on any old game or betting market. There are 64 teams, 67 games, and thousands of
NCAA March Madness betting lines
to choose from.
March Madness is known for its team parity, high level of jeopardy, and crazy unpredictability
(they don’t just call it “Madness” because of the alliteration!). This means that there is no quick fix or strategy to guarantee wins with your March Madness betting promos.
Still, as someone who has a wealth of experience in this field, I’m well-placed to provide you with some top tips to help use your bonus to enhance your overall March Madness betting experience in 2025:
An obvious one to start with, but the first thing that you need to do is pick the right offer based on my advice above.
Check the bonus time limits and make sure that you claim the bonus within the right time frame to bet on the round you want to use it for.
The good thing about March Madness is that the parity between the teams levels out the odds. Still, I would avoid longshot bets at high odds with no chance of winning and short-odds favorites with no value.
A simple but solid piece of advice; never spend or bet money you can’t afford just to take advantage of March Madness betting promos.
If your bonus has a playthrough condition, make sure that you meet it on time so that you don’t lose your bonus and winnings.
There you have it – five legit March Madness betting promos so that you can avoid the scammers. Now all that you need to do is choose the right one for you, sign up to the betting site, and get started.
Remember that it’s not all about getting your hands on the bonus – it’s how you use it. To help along the way, you can always bookmark this page and revisit me here at GameChampions.
