Reviews of the Best March Madness Second Round Sportsbooks

The leading offshore sportsbooks are all trustworthy and reliable, but they have different areas of expertise. Keep reading to discover your best fit.

1. BetOnline – Best All-Round Sportsbook for March Madness

Sportsbook facts: 

• Website: betonline.ag
• Payout Time: Same Day
• Established: 1998
• License: Government of Costa Rica

Our Verdict: 4.8/5

BetOnline is our top choice for betting on the second round of March Madness. Rival sportsbooks are slow to release their second round lines, which does not give you much time to place your bets. This sportsbook stands out by releasing quick, overnight lines, and sharp bettors can often find early value, as it always takes a relatively low house edge on its lines.

March Madness Options at BetOnline: 4.7/5

There are lots of markets to choose from when betting on the NCAA Tournament at BetOnline. You can browse alternate spreads and totals, along bets on either half and a long list of props. Wagers such as parlays, same game parlays, teasers, pleasers, if bets, reverse bets, action reverse bets and progressive parlays are also available. There is also a strong in-play section, featuring live March Madness streaming.

Payment Options: 4.8/5

You can deposit between $20 and $500,000 if you use Bitcoin at BetOnline. There are various other options, including altcoins, credit cards, debit cards and P2P payments, although the limits are slightly narrower. Payouts are processed rapidly, so you normally get your money on the same day it is requested if you choose crypto.

Bonuses & Promos: 4.8/5

You will get up to $1,000 as your welcome bonus at BetOnline. The size of the deposit match and the rollover requirements depend on whether you use a fiat-based payment method or crypto, as highlighted in the table below. It provides a large reload bonus too, along with a risk-free live bet, odds boosts and a $250,000 March Madness bracket contest.

2. Bovada – Best Selection of Prop Bets on College Basketball

Sportsbook facts: 

• Website: bovada.lv
• Payout Time: Same day
• Established: 2011
• License: Government of Costa Rica
• Headquarters: Costa Rica

Our Verdict: 4.7/5

Bovada is another excellent option for March Madness second round betting. It provides more prop bets than offshore rivals such as BetOnline, BetUS and MyBookie, and the layout is very user-friendly. Its flagship bonus comes with a realistic rollover requirement, and there is an excellent loyalty program too.

March Madness Options at Bovada: 5/5

Bovada offers lots of exciting props to choose from on college basketball games. There is also a prop builder, and you can browse various alternate lines, along with pre-game stats. It has a featured called #Whatsyawager too, which allows you to get odds on any prop that is not featured on the site.

Payment Options: 4.2/5

Bovada offers a similar selection of fiat-based and crypto payment methods to BetOnline, although its upper limits are lower. You can use Bitcoin, Litecoin, Bitcoin Cash, Ethereum, debit or credit cards, voucher payments and a few other options. The payment process is smooth and secure, and it is very quick to pay out.

Bonuses & Promos: 4.6/5

You will either get a 50% free play if you use a fiat payment method for your first deposit or a 75% free play up to $750 if you use crypto. These bonuses come with relatively low rollover requirements. Bovada does not have as many additional promos as BetOnline and BetUS, but there is a competitive rewards program.

3. BetUS – Largest Promotions for NCAAB Bettors

Sportsbook facts: 

• Website: betus.com.pa
• Payout Time: 24-48 hours, depending on the mode of payment
• Established: 1994
• License: Government of Curacao

Our Verdict: 4.6/5

BetUS bills itself as “America’s Favorite Sportsbook.” That wasn’t always the case, as it had some payout issues a decade ago, but a new management team came in and transformed its fortunes. It now lives up to its billing by offering an impressive all-round user experience and secure, reliable payouts for all customers.

March Madness Options at BetUS: 4/5

BetUS has broadened its range of betting options over the past few years. You can bet on alternate spreads and totals, winning margins, team totals and lines on either half. There are some props on big NCAAB games too, but it does not offer as many markets as Bovada or BetOnline.

Payment Options: 4.2/5

You can use Bitcoin, Ether, Bitcoin Cash, Litecoin, Visa, MasterCard, American Express, a bank wire or a cash transfer to fund a BetUS account. The limits are $10 to $50,000 per deposit if you use crypto, and $50 to $5,000 per withdrawal. Limits on fiat-based methods are lower.

Bonuses & Promos: 4.8/5

You can choose from a wide array of bonuses at BetUS before betting on March Madness 2nd round games. The options include fiat and crypto sign-up bonuses worth up to $3,125, along with huge reload bonuses and a lucrative refer-a-friend offer.

4. BC.Game – Best Crypto Sportsbook for March Madness

Sportsbook facts: 

• Website: BC.Game
• Payout time: Same day
• Established: 2017
• License: Gaming Curaçao
• Headquarters: Curaçao

Our Verdict: 4.6/5

BC.Game is a high-quality crypto sports betting site. It has an international outlook, so soccer is often the main focus on the homepage, but it also offers comprehensive basketball coverage. You will notice that the site is stylistically different to BetOnline, Bovada and BetUS, with a darker and more stylish aesthetic, a larger selection of features and a more polished user experience, so it makes a compelling alternative.

March Madness Options at BC.Game: 4.6/5

It is worth noting that BC.Game does not officially accept players from the United States, but you can easily access the site using a VPN. You will then be presented with a very broad and impressive selection of betting options.

They include loads of props, alternate lines and combo markets (same game parlays), which are displayed in an accessible format, along with detailed pre-game stats. The only frustration is that you cannot create your own same game parlays, as you can only choose from those created by BC.Game.

Payment Options: 4.2/5

This is a crypto sports betting site, which accepts coins on more than a dozen different blockchains. You can consider from a long list of altcoins, including some smaller cap coins. The payment limits are very broad, and withdrawals are rapid and secure.

Bonuses & Promos: 4.3/5

You will get up to 1 Bitcoin as your deposit match welcome bonus, which is a huge offer. However, it does come with high and complex rollover requirements. There are three huge reload bonuses available too, along with recurring promos.

5. XBet – Beginner-Friendly NCAAB Betting Site

Sportsbook facts: 

• Website: xbet.ag
• Payout Time: 48 hours
• Established: 2014
• License: Government of Costa Rica
• Headquarters: Costa Rica

Our Verdict: 4.5/5

XBet is a simple, beginner-friendly sportsbook for college basketball fans. It looks very rudimentary if you compare it side-by-side with a modern site like BC.Game, but this is a solid sportsbook. XBet has a strong US focus, so March Madness takes pride of place during the spring, with regular news articles and contests promoted on the homepage.

March Madness Options at XBet: 4.2/5

XBet is not as quick to release its March Madness second round betting lines as rivals such as BetOnline and Bovada. It also provides a narrower choice of markets. However, it is a great option for any newcomers that want to simply bet on the spread, moneyline or total, and it sometimes has market leading odds and lines.

Payment Options: 4.5/5

You can use Bitcoin, Bitcoin Cash, Litecoin, a P2P transfer, a credit card or a debit card to fund your XBet sportsbook account. Payments can go up to $10,000 via crypto or $2,500 via a fiat payment method. It is not as fast at processing withdrawals as the other brands in our top five, but it always delivers safe, reliable payouts.

Bonuses & Promos: 4.4/5

There is a 50% free play bonus worth up to $500 at XBet, which has a 7x rollover requirement. You can also claim a 25% reload bonus, but it offers fewer recurring promos than BetOnline and BC.Game.

6. Lucky Block – High-Quality Sportsbook with Lots of Features

• Website: luckyblock.com
• Payout Time: Same Day
• Established: 2022
• License: Curacao Gaming Control Board
• Headquarters: Cayman Islands

Our Verdict: 4.5/5

Lucky Block is another elite crypto sports betting site and online casino. It is not quite as established as BC.Game, but it is a very credible rival. The software is just as impressive as BC.Game’s, and it offers attractive odds, but there are no sports betting bonuses, so it has ended up further down our list.

March Madness Betting Options: 4.9/5

Once again, American sports bettors must use a VPN to access Lucky Block. You will then find an exciting range of NCAAB betting options. It uses European terms, but they are straightforward and you will soon get used to them. You can also check out helpful statistics on both teams before placing your bets at Lucky Block.

Payment Options: 4.5/5

This is a crypto betting site, so you can use Bitcoin, Ethereum or various additional altcoins to make deposits and withdrawals. If you do not have any crypto, you can use a credit card or debit card to buy some at Lucky Block, and you can then use it to place bets on the NCAA Tournament.

Bonuses & Promos: 0/5

Unfortunately, Lucky Block does not offer sports bettors a welcome bonus right now. There are no promotions for existing sports betting customers either. It does offer a casino bonus, so hopefully a sports betting offer will be added at some point.

7. SportsBetting.ag – Offers Very High Betting Limits

Sportsbook facts: 

• Website: sportsbetting.ag
• Payout Time: 24-48 Hours
• Established: 2003
• License: Government of Costa Rica
• Headquarters: Costa Rica

Our Verdict: 4.5/5

SportsBetting.ag is a sister site of BetOnline, our top March Madness sportsbook. It has all the same lines, markets, odds, bonuses, promotions and payment methods. The only difference lies in the software – BetOnline has been upgraded, making it a modern and stylish sportsbook, whereas SportsBetting.ag still uses the old, dated technology.

March Madness Options at BetOnline: 4.7/5

While it may not be as aesthetically pleasing as BetOnline, this sportsbook still offers the same early lines, competitive odds and broad selection of prop bets. As such, it fully merits a place on this list, and you can sign up with SportsBetting.ag if you prefer a more basic, stripped-back layout.

Payment Options: 4.8/5

Once again, there are lots of crypto and fiat-based payment options, with huge upper limits. SportsBetting.ag and BetOnline welcome high-stakes sports bettors, with high wagering limits and a re-bet option, which you can use to bet on the same market again and again at 61-second intervals until reaching your desired total stake.

Bonuses & Promos: 4.8/5

You can choose from the same 50% up to $1,000 fiat bonus or the 100% up to $1,000 crypto bonus. It is also running a $250,000 bracket challenge, which has a $25 entry fee, along with a few additional promos for NCAAB bettors.

8. Everygame – Trustworthy Sportsbook for March Madness

Sportsbook facts: 

• Website: everygame.eu
• Payout Time: 5 working days
• Established: 1996
• License: Curacao e-Gaming Authority
• Headquarters: Antigua and Barbuda

Our Verdict: 4.5/5

Everygame is the oldest college basketball betting site in the world. It has been taking bets since the mid-1990s, initially as Intertops before rebranding as Everygame in 2021. This is a solid all-round sportsbook. It could offer more betting options and larger bonuses, but it is trustworthy and dependable, and it has some interesting promos.

March Madness Options at Everygame: 4/5

You can bet on the moneyline, spread and total at Everygame. It offers a few additional pre-game lines, along with some live betting markets. Parlays, teasers and round robins are available too. However, you will find far more choice at rivals such as Bovada.

Payment Options: 4.4/5

Everygame offers one of the largest ranges of payment options in the business. They include Visa, MasterCard and American Express, plus Bitcoin, Bitcoin Cash and Litecoin, and alternative methods such as PaySafeCard, ecoPayz and EZeeWallet. It has lower limits than many competitors featured on this page, but payments are always reliable and simple.

Bonuses & Promos: 4.2/5

You will get a 100% free play bonus of up to $50 on each of your first three deposits. These bonuses have an 8x rollover requirement. This does not represent a particularly exciting welcome offer, as it is a lot smaller than the bonuses at rival sites. However, Everygame makes amends by running fun monthly parlay promos, contests and insurance deals, plus an excellent refer-a-friend offer.

9. MyBookie – Competitive College Basketball Odds

Sportsbook facts: 

• Website: mybookie.ag
• Payout Time: Payouts within 48 hours
• Established: 2014
• License: Government of Curacao
• Headquarters: Costa Rica

Our Verdict: 4.5/5

MyBookie is the sister site of XBet. Unlike BetOnline and SportsBetting.ag, MyBookie and XBet use the exact same platform, so they are identical – albeit with a slightly different color scheme. However, they also have different bonuses, so you can choose the site that appeals the most.

March Madness Options at MyBookie: 4.2/5

MyBookie provides the same betting options as XBet – spread, moneyline, total, alternative lines and some props. It would be great to see these sites releasing their lines a little quicker, but they do sometimes have very appealing odds on specific markets, so it is always worth considering them when comparing NCAA Tournament odds.

Payment Options: 4/5

The same set of fiat and crypto payment options are available at MyBookie as XBet. Bitcoin is the best choice, as payments are free and you can send up to $10,000 per transaction. Ethereum, Litecoin and Bitcoin Cash are also available, along with Visa, MasterCard and P2P transfers.

Bonuses & Promos: 4.7/5

MyBookie has a larger sign-up bonus than XBet – a 50% free play up to $1,000 – although it has a larger 10x rollover requirement. There is an alternative too – a 10% cash bonus up to $200, with a simple 1x rollover requirement – so that is a great option if you do not want to wrestle with high wagering requirements.

10. BUSR – Impressive Racebook with NCAAB Betting Section

Sportsbook facts: 

• Website: busr.ag
• Payout Time: 3-5 days, dependent on the method
• Established: 2014
• License: Government of Curacao
• Headquarters: Costa Rica

Our Verdict: 4.4/5

BUSR rounds out our top 10 sportsbooks for the NCAA Tournament. It started out as a racebook but it then added a thorough online sports betting platform. The site is not as strong as rivals like Bovada and BetOnline, but any horseplayers that want to bet on March Madness should enjoy the service.

March Madness Options at BUSR: 4/5

You can bet on the spread, total, moneyline and various alternate lines at BUSR. It publishes some prop betting options on NCAA Tournament games too, but it would be nice to see a wider selection of markets added at some point.

Payment Options: 4/5

Visa and MasterCard are available for payments, along with Bitcoin, Ether, Litecoin, Bitcoin Cash and a P2P transfer. Withdrawals generally take at least three days to arrive, so this is another area in which BUSR could potentially improve. You get one free Bitcoin withdrawal per month, worth up to $5,000.

Bonuses & Promos: 4.2/5

There is a huge sign-up bonus of up to $2,500 at BUSR. It comes with a 10x rollover requirement, but it is nevertheless a large promo if you think you can complete it. The reload bonus is worth up to $500 too.

How to Place Bets on March Madness Second Round Teams

It is easy to place sports wagers on March Madness 2nd round games. Just follow the steps we have listed below to get started:

Step 3: Make a Deposit

You will need to fund your account in order to place bets on your March Madness second round picks. Visit the cashier by clicking the green button at the top of the homepage.

2023 March Madness Second Round Odds

March Madness second round odds will be shown in the American format at most sportsbooks. As such, they will start with a plus or minus sign. Here is an example of March Madness second round betting odds:

• Providence to beat Richmond (-135)
• Richmond to beat Providence (+115)

When the odds start with the minus sign, the subsequent number tells you the amount you would need to bet to net a $100 profit. A $135 bet on Providence would earn you $100.

If they start with the plus sign, the number explains the profit available from a $100 bet. A $100 wager at +115 on Richmond would net you $115 in this example.

Types of March Madness Second Round Bets & Features

This section will explain the key March Madness second round betting options and features at your disposal.

Moneyline Bets

This is a straightforward NCAAB bet on the winner of a game. For example, you might be offered odds of -235 on Tennessee to beat Michigan, and +190 on Michigan to win the game. The odds explain your potential profit, as described in the section above. Just pick who you think will win and make your play.

Spread Betting

The NCAAB spread arises when the sportsbook gives the team deemed stronger (moneyline favorite) a points handicap. You then find similar odds on either of them covering it. Using the example above, you would expect to see -110 on Tennessee -5.5 points and -110 on Michigan +5.5 points.

Totals

An over/under bet on the number of points both teams will combine for. You may find -110 on over 137.5 points and -110 on under 137.5 points, as an example. There will be alternate totals and team totals too.

Prop Bets

These special betting markets focus on player performance stats, team performance stats or events inside a game. They might include a bet on a player to score a certain number of points or the first team to reach 15 points in the game.

Parlays

A parlay rolls at least two separate NCAAB picks into a single, multi-legged wager with increased cumulative odds. For example, you might bet on Villanova, Houston, Wisconsin and Arizona all to cover the spread. All four need to cover for that bet to succeed.

Live Betting

You can place in-game bets on NCAA Tournament second round games. The sportsbooks update the odds and lines on markets such as the spread, total, moneyline and certain props according to the score throughout the game.

Live Streaming

Live streaming is available at a couple of NCAA basketball betting sites, including BetOnline. This allows you to watch and bet in the same place.

Bets Available at Each Sportsbook

This chart highlights the main March Madness second round betting options available at the top 10 NCAAB sportsbooks:

March Madness Second Round Schedule

The March Madness second round schedule gets underway on March 16 and it will conclude on March 19.

March Madness Second Round Predictions

If you are looking for second round predictions, March Madness bettors can return to this page after the first round games have concluded. It is important to watch as much action as possible throughout the first round of the NCAA Tournament, as that can be invaluable when making second round picks.

March Madness Second Round Favorites

No. 1 seeds always win their second round matchups, so avoid betting against them on the moneyline. They are 103-1 straight-up and 59-45 ATS (against the spread) in the first and second rounds over the past 27 years, so backing No. 1 seeds to cover is often a lucrative pursuit in the second round

On the flipside, while No. 2 seeds are 97-7 straight-up, they are also 46-58 ATS, so fading them when betting on the point spread can be worthwhile. If you had simply bet $50 blindly on each No. 1 and N0. 15 seed to cover over the past 27 years on the first two rounds, you would be up by more than $1,000.

March Madness Second Round Upsets

Of course, we witnessed a major second round upset last year. Saint Peter’s beat No. 2 seed Kentucky in the first round, and then went on to beat No. 7 seed Murray State by 10 points in the second round.

Everyone will naturally be on the hunt for this year’s Saint Peter’s. Return to this page when the first round games have concluded for our top picks on second round upsets.

The Best March Madness Betting Site

We rate BetOnline as the best online sportsbook for betting on the second round of the NCAA Tournament. It is quick to publish second round lines after the first round game concludes, which is helpful during this frenetic event. You will find competitive odds too, along with a wide choice of markets, and the betting limits are very broad.

If you sign up today, you will get a bonus of up to $1,000 to welcome you into the fold. It also offers a risk-free live bet, a large March Madness bracket contest, same day payouts, 24/7 customer service and excellent software, so it is the best all-round site for NCAAB betting. Click the button below to create your account and start betting on the NCAA Tournament.
