You’ll find moneyline bets for a wide range of sports, including the NFL, NBA, NHL, MLB, and college sports. We especially like MyBookie for NBA betting because this site has a huge selection of futures bets. You can wager on who will be next year’s league MVP or which team will win the NBA East. The prop bet offerings for even regular season NBA games is also extremely impressive.

MyBookie makes it easy to place bets and especially to build complex parlays. There’s a parlay builder that lets you mix and match wagers including prop bets, over/under bets, and moneyline bets, so you can bet on a single game from dozens of different angles.

Odds for live bets are updated in real time in response to the action, and you’ll even see new prop bets appear midway through major matches.

Bovada offers live streaming and betting for a wide range of sports, including football, basketball, soccer, tennis, MMA, motorsports, esports, and golf. This betting site also takes wagers for less popular sports like skiing, beach volleyball, and ice skating. While you won’t find many prop bets in these niche sports, the fact that Bovada has them at all is a huge plus for this platform.

This online betting site supports payments with credit cards, debit cards, crypto, and Zelle. You can withdraw as little as $10 at a time with no fees, which is a helpful policy. Plus, Bovada routinely delivers your money in less than 24 hours.

Bovada offers a $750 welcome bonus for new players through a 100% deposit match. The only catch is that you must deposit Bitcoin or another cryptocurrency – debit, credit, and Zelle deposits don’t qualify. The bonus requires you to play minimum odds of 2:1 or greater and doesn’t have a time limit. Use promo code BTCSWB750 to claim your welcome bonus today.

You’ll also find a racebook for betting on thoroughbred and harness races.

BetUS supports in-game betting, although it doesn’t have live streaming. Wager odds are updated in real time and it’s easy to modify your betslip with just a few clicks. We especially like that BetUS has a mobile-friendly website, so it’s easy to place wagers from anywhere, anytime.

BetUS stands out most for its massive welcome bonus: new players can claim up to $2,500 with a 125% deposit match. You can qualify for the bonus by making a deposit with a credit card, debit card, or cryptocurrency, and it’s good for wagering on anything with odds of 2.8:1 or higher. The only catch is that you only have 14 days to meet the wagering requirement. Use promo code JOIN125 to claim your BetUS welcome bonus today.


  • Bet on US & international sports markets

Best Online Sportsbooks US-based:

When the team at BBI reviews the best betting sites available to use in the US, sites that are easy for ALL US citizens to access tend to take precedent. So, geo-restricted sites tend to get left off.

However, there are a growing number of states that either provide legal access to – or are in the process of allowing – blue-collar, onshore sports betting sites to operate within their confines.

As such, below we’ve listed out and reviewed the best onshore sports betting sites currently available to those bettors fortunate enough to live in states that are not geo-restricted:

1. Fanduel - Best US Online Sportsbook Overall

1. Fanduel – Best US Online Sportsbook Overall

Available in the following states: NJ, PA, WV, IN, CO, IL, TN, IA, VA, MI & AZ, FanDuel is one of the best US online sportsbooks in several categories:

FanDuel is atop the pile when it comes to Fantasy Sports, providing bettors with a chance to create and wager on their favorite stars from the worlds of the NBA, MLB, and NFL each week. Sports fans also have the choice of whether or not to play Fantasy for free or to play for real money.

In terms of the betting markets available, FanDuel boasts 20 separate sports to bet on and is in direct partnership with the big leagues in the US, which provides the betting site with exclusive access to NFL/NBA/MLB/NHL logos, etc. Live betting is available; it’s simple to make creative parlays; easy to bring up detailed statistics for whatever sport you’re looking to wager on, and the odds tend to be very competitive. There is also a dedicated horse racing page for those of you who like to wager at the track.

Besides being one of the best online sportsbooks US, Fanduel’s mobile application works great with both Android and iPhone. It’s easy to download, install, and navigate; we’ve never encountered any lagging on the live markets when using it either. It is worth noting, however, that there are separate apps for the sportsbook and fantasy sports.

Besides all that, FanDuel is also one of the best US online sportsbooks when it comes to bonuses and promotions: at present, the sportsbook is offering a $2,000 risk-free bet to all newcomers to the site; there are risk-free $10 bets on same game parlays for all customers, as well as NHL parlay insurance and a host of enhanced odds bets across the NBA.


  • Best online betting site for Fantasy NFL, MLB, and NBA
  • Beautifully designed app – hard to fault
  • Best sports betting site for Enhanced Odds on NBA
  • Live in-game betting
  • Competitive odds
  • Officially licensed sports betting site: NBA, MLB, NFL (and more)


  • Other sites boast deeper sports betting markets
2. DraftKings - Best Sports Betting Site for NCAA football & basketball

2. DraftKings – One of the Best Online Sportsbooks for NCAA Football/Basketball

It might not look as polished as some of the competition, but the DraftKings’ sports betting site (and the mobile app) does everything required of it, providing a great betting experience across the board:

Currently available in Pennsylvania, New Jersey, Indiana, West Virginia, Colorado, Illinois, Tennessee, Michigan, and Virginia, Draftkings provides bettors with deep, DEEP markets for all listed sports and provides outstanding betting coverage of NCAA basketball & football in particular.

Taking the above NCAA football game between Tulane and SMU as an example, DraftKings patrons are able to bet on the spread, moneyline, or total points markets and create a parlay for better odds. It’s also possible to bring up stats for all the recent matches, as well as to read DraftKings exclusive NCAA picks and tips before you place your wager on the game – it’s a very fleshed-out betting experience.

Like Fanduel, DraftKings also offers an excellent selection of fantasy sports, too.

The icing on the cake with this US sports betting site is the selection of bonuses available: newcomers to DraftKings are entitled to free bets, there are free-to-play pools and an invite-only VIP program.


  • Trusted US online sportsbook and betting app
  • Deep sports betting markets
  • Online sports betting site that’s great for live, in-play markets
  • Great selection of Fantasy Sports
  • East to create Parlay bets
  • VIP program


  • Doesn’t tend to offer the best odds available
3. FOXBET - Best Sports Betting Site for Competitions/ Tournaments

3. FOXBET – Among the Best Online Sportsbooks for Tournaments & Competitions

FOXBET is only available in four states: New Jersey, Pennsylvania, Michigan, and Colorado. But, if you’re fortunate enough to be resident in one of those states, it’s one of the very best sports betting sites available on the market right now.

Being that first and foremost FOX is a world-renowned sports broadcaster, the betting site grants its patrons instant access to all the latest NBA, NFL, and MLB news that’s written by some of the biggest names in the business.

The site features regular and live betting markets for 15 sports in total, including the big four in the US: basketball, baseball, football, and hockey. For each of these sports, in particular, FOXBET is chocked full of statistics, enabling bettors to seamlessly do their homework before wagering.

FOXBET also ranks near the top when it comes to bonuses and competitions: there’s a $500 risk-free bet available to any new customer; bonuses on parlays; free $5 bets each week for TNF, and a super boost feature each Friday called ‘Happy Hour.’ Plus, that’s just for starters! At FOXBET, it’s also possible to win big money on the site’s Super 6 feature; there are rewards for creating your own bets, and much, much more – it’s well worth taking a look if you haven’t already.


  • Excellent selection of onboarding and in-play bonuses
  • Deep prop betting markets
  • Excellent sports betting site for stats and analytics
  • Sports blog pages written by top analysts
  • Super 6
  • Licensed betting partner of NFL, MLB, & NBA


  • Doesn’t tend to broadcast the best odds
  • Limited availability; operates in just four states at present
4. BetMGM - Best Sportsbook Betting Site NFL Spreads

4. BetMGM –  Best Sportsbook Online for Football Spreads

Available in 13 states to date, BetMGM is an officially licensed betting partner of the NFL, NBA, & MLB, and offers a variety of excellent features, including flash odds, cash-out options, and live streaming.

Of all the sports betting sites US citizens have access to, we particularly recommend BetMGM for NFL parlay bets. In the image above, you’ll notice on the bet slip that it’s possible to wager on both parlays and round robins – more options are always great.

However, the reason we rank BetMGM so highly regarding accumulative bets is that, firstly, the site creates its own parlays based on recent events and presents them to you. So, you can wager on results + props at the click of a button. And, secondly, the Las Vegas odds on offer are usually among the best available anywhere – particularly when you add them together to create a parlay. Also, there’s parlay betting insurance and 4-7 leg parlays are often enhanced by 40%.

On top of that, BetMGM offers a five-tier loyalty program: Sapphire, Pearl, Gold, Platinum, and Noire, with prizes ranging from special sportsbook offers, to free stays at MGM-owned property. And, it’s one of the best online sportsbooks when it comes to bonuses too: new BetMGM patrons are entitled to a risk-free $1,000 bet when they sign up and the sportsbook literally gives away $10 bets each week!


  • Great loyalty program
  • One of the best online sportsbooks for parlay betting on NFL & MLB
  • Smooth running app
  • One of the best sportsbooks for live streaming – great quality
  • Solid coverage of niche sports
  • Broadcasts Flash Odds
  • Best sportsbook betting site for Las Vegas odds.


  • Limited selection of eSports betting markets
5. Bet Rivers - Best Sports Betting Site for Stats & Analytics

5. Bet Rivers – One of the Best Sportsbooks Online US for Stats & Analytics

BetRivers is one of the best sportsbooks online when it comes to the depth of options available to bet on: the site has markets open for all the mainstays like the NFL, NBA, and MLB, as well as less popular sports like table tennis and cricket. Each featured sport boasts a variety of game lines and prop betting options to boot. In fact, it’s not uncommon to find upwards of 70+ individual betting lines for an NBA game (for example).

On top of that, BetRivers is also a fantastic site to use when studying up on your wager. In the image above, you’ll notice BetRivers provides in-depth statistics on NHL games, for example. It’s easy to see all the recent results; the recent results between the two teams; the recent form of the players, and so on…

Plus, in amongst the analytics, BetRivers also shares with its customer base Genius Facts relating to the game. So, in the above image, it’s easy to see that the Pittsburgh Penguins’ last four games have gone over the total goals margin, and so on. This all helps when it comes to placing winning bets.

BetRivers is also a powerhouse when it comes to bonuses and promotions. There’s a $500 welcome bonus, NFL parlay boosts each week; 20% MLB profit boosts on Wednesdays & Fridays, as well as a $1,000,000 beat the spread contest that’s running throughout this year’s NFL – plus plenty more where that came from, including the BetRivers iRush VIP rewards program.


  • One of the best online sportsbooks for US players who use stats to wager
  • Parlay boosts
  • Deep betting markets
  • iRush VIP rewards
  • Among the best online sportsbooks for USA live betting


  • Lack of live streaming options

How We Select the Top Betting Sites

At BasketballInsider, we analyze the best online betting sites online find out where they excel and where they fall short. Here are some of the criteria we use to judge the top online betting sites:

Licensing & Security – This is crucial. The best sports betting sites will make every effort to safeguard their players online. This means having the latest SSL (Secure Socket Layer) encryption installed. In addition, the best online betting sites will be fully licensed and regulated – including the best offshore sportsbooks. Don’t fall for sites that have poor reviews or look dodgy.

Range of markets – All of the best online sportsbooks will offer a wide range of sports. But there’s more to betting markets than just what sports are available. You want to make sure that a top sportsbook has a wide range of prop bets, over/under bets, parlay options, and more. The more options you have for how to bet, the better.

Odds – It can be tough to compare odds between online betting sites since they’re different for every match and can change for live betting. That said, be sure to shop around before a big game if you want to get the best possible odds for your bets.

Free Bets & Bonuses – The best online US sportsbooks will pull out all the stops to get you to sign up. Welcome bonuses can add up to a lot of money, and we take that into account when recommending top online betting sites. We also look at the terms and conditions for using these bonuses.

Live Betting & Streaming – Bettors who like to see the live-action unfold will want access to live betting markets. While it is not always easy to find betting sites that have a live stream, live betting markets are essential. In fact, most top sportsbooks including BetOnline, MyBookie, and Bovada have plenty of markets to bet on in-play.

Usability on Desktop & Mobile – The best online sportsbooks will have spent a lot of time investing in the digital side of their operations. We look for sportsbooks that offer intuitive desktop sites where you can easily place bets. We also weight our analysis towards mobile betting sites that let you place wagers from anywhere while you’re on the go.

Special Features – Some top online sportsbooks offer special features, such as the prop builder at MyBookie. Other sportsbooks offer Request A Bet, which lets you get in touch with a bookmaker via Twitter to find out prices for specific events. Special features will resonate with some bettors, especially if they are more adventurous with their wagers.

Customer service – Bettors want reassurance that they can contact a sportsbook day or night if they run into trouble. The best betting sites in the USA offer 24/7 customer support by email and live chat at least. Intertops, for example, can be reached through live chat, phone, email, and Skype, so they are a go-to bookmaker if you appreciate excellent customer service.

Guide to American Sportsbooks

The sites we have discussed so far in this guide are highly recommended, and they are well known within US betting circles. In the following sections, we will take a closer look behind the scenes to see how American sportsbooks operate. We will delve into the bonus element of US sportsbooks, payment methods, as well as the kinds of markets you can wager on.

Are Sportsbooks Legal in the US?

US-based sportsbooks have, at times, had a strained relationship with the law. While sports betting is deemed legal in some states, it is not legal everywhere. Currently, just 10 states permit sports betting online. In 2011, the Supreme Court overturned the federal ban on sports betting, meaning states would be allowed to choose whether to legalize sports betting. In some cases, US citizens may have to travel across the country just to bet on sports.

In the graphic seen above, the states colored in green are those that tend to allow American-operated sportsbooks, though not every sportsbook is permitted in each ‘green’ state – you’ll have to double-check to ensure your preferred option is legal in your state of residence.

It’s for this exact reason that we often recommend offshore betting sites such as BetUS and MyBookie. These are available, by and large, nationwide. However, it’s worth pointing out that offshore betting sites are not legal in any state – even in states that allow online sports betting, only sites that are regulated by the state’s gambling commission are allowed to operate legally.

Markets & Odds

While you might think of simply betting on the outcome of a match as sports betting, there’s a lot more to bet on than just the final score. Here, we’ll cover some of the most popular sports betting markets you’ll find at top online betting sites.

  • Moneyline Bets: A moneyline bet is a bet on which team will win a match. This is the simplest and most popular type of bet at the best sports betting sites.
  • Prop Bets: Prop bets are wagers on events that don’t directly impact which team will win. For example, a prop bet might let you wager on which team will be winning at halftime or on which player will score the most points.
  • Over/Under Bets: Over/under bets let you wager on whether some metric will be above or below a threshold set by the sportsbook. For example, you could bet on whether a team will score over or under a certain number of points.
  • Correct Score Bets: In a correct score bet, you’re wagering on a game’s final score. You must get each team’s score exactly right to win your bet.
  • Futures Bets: Futures bets are bets on events that will happen in the future – and not necessarily individual games. For example, you can place a futures bet on which team will win next season’s league championship or which player will be the league MVP.
  • Parlay Bets: Parlay bets let you combine 2 or more bets into a single wager. For example, you can bet that one team will win Game A, and another team will win Game B. For your bet to win, you must be right about both individual bets.
  • In-game Bets: In-game bets let you bet on a game live as it unfolds. Odds are updated in real-time in response to the action. Live betting is popular because you can see how the game is going before placing a wager.

For any wager, the payoff you’ll receive if you win is determined by the odds. Odds can be written in several different ways, but most US sportsbooks use American odds. In this system, the favorite is indicated by a – sign and the number indicates the amount you need to wager to win $100. So, if the odds are -500 for a bet, you need to wager $500 to win $100. The underdog is indicated by a + sign, and indicates the amount you’ll win for every $100 you wager. So, a +250 odds indicates that you would win $250 if you wager $100.


It’s also important to think about what odds you’re getting for any specific wager. The top sportsbooks typically offer competitive odds for big matches, but odds can start to look very different when betting on matches that don’t get a lot of attention.  Be sure to compare odds across a few top sportsbooks before placing a bet.

Sportsbook Betting Bonuses

The best online sportsbooks boast tantalizing sign-up offers and welcome bonuses to whet the appetites of bettors. Below are some of the most common types of promotions you may encounter.

Free Bets

Free bets are a chance to bet on any wager for free. The name is a bit deceiving, however, in that you do need to make a deposit to the sportsbook first and temporarily risk your own money. If you win the bet, you get to keep your winnings. If you lose the bet, the sportsbook will reimburse you for the amount you wagered – so, you don’t lose any money at all.

Risk-free Bets

Risk-free bets are free bets in which you never have to wager your own money. In fact, you don’t even need to make a deposit to your sportsbook account – just sign up and the betting site will give you money to start wagering with. If you win, you can keep the winnings and continue betting. If you lose, you have the choice to deposit funds or simply walk away.

Matched Deposits

Matched deposit offers are the most common type of welcome bonuses you’ll see at online betting sites. With this type of bonus, the amount you receive is contingent on how much your deposit. At BetOnline, for example, if you deposit $800, the sportsbook will give you $800 on top of that.

Key Terms of Betting Bonuses

The prospect of wading through line after line of terms and conditions can seem rather arduous. So here are some of the most common phrases relating to bonuses and what they mean.

Wagering requirements – Here, bettors have to play through a bonus before they can withdraw any winnings. Playthrough requirements may be presented as 40x, so if you bet $20, you would need to spend $800 before being able to claim any winnings.

Minimum odds – Referring to the lowest odds you can bet to convert a bonus into cash, the best sportsbooks will typically hold minimum odds that range from 1.50 to 2.00.

Validity period – This is the time you have to use your bonus before it expires. The sportsbook should allocate enough time for these to be used, but typically bonus periods last from anywhere between 7 to 30 days.

Minimum deposit – This is the lowest amount you must deposit into your playing account before you can accept, and qualify for the bonus. Always be wary of what the minimum deposit is, otherwise you will be discounted from the offer.

Maximum winnings – The most you can win from any bonus offered. Limits are imposed, so as to protect the best sportsbooks, and ensure they continue to generate profits.

Mobile Sports Betting – Top Sportsbook Apps

With more sports betting happening on the go, the top online betting sites have worked hard to deliver seamless mobile experiences for players. Some sites now offer dedicated betting apps for iOS and Android, while others like MyBookie and Bovada have mobile-friendly sites that you can access through your smartphone’s browser.

When comparing mobile betting apps, be sure to check that you have access to the same betting markets on your smartphone as you do on your desktop. In addition, it should be easy to open your betslip, browse upcoming matches, and modify your wagers with just a few taps. The easier it is to place bets from your smartphone, the better.Darts Betting App Bovada

New US Betting Sites

The gambling landscape is constantly shifting in the US. With the expansion of legal sports betting around the country, there is a new wave of new betting sites to explore. Ultimately, these sites have to be granted a new license, but the ones that are currently in favor with bettors will have a wealth of special features, such as ‘Edit my bet’ or ‘Prop builders’ to give bettors room to customize their own wagers.

What will also make them stand out, is the strength of the odds, as well as the markets on offer. As we have seen, odds boosts have been adopted by the best sportsbooks in the US, while those that provide Cash Out will appeal too. Fundamentally, the best sportsbooks will advertise juicy promotions, so as to captivate the attention of new bettors, and ultimately keep them at their site.

Payments at the Best Online Sportsbooks & Betting Sites

Making payments at top online betting sites needs to be simple and quick. That’s why most sports betting sites accept not only debit and credit cards, but also e-wallets like Skrill, Neteller, and ecoPayz. Some even accept PayPal.

On top of that, many online betting sites now accept cryptocurrencies for payment. For example, at BetOnline, you can pay with Bitcoin, Bitcoin Cash, Ethereum, Litecoin, or Ripple. Cryptocurrency withdrawals are low-cost and extremely fast. Just keep in mind that you may not be able to deposit and withdraw using the same payment methods, so check before proceeding.

Top Sports Betting Tips

When it comes to sports betting, you need to have a concrete strategy in place to improve your chances of success. Below are five betting tips to bear in mind:

Soak up tips – The best online betting sites will have an army of in-house writers, who will write previews before tip-offs of big NBA games. Tap into their knowledge, and then apply it to your bets.

Keep records – Every bet should be carefully noted. Learn from which bets were successful, and which were less so, and then adjust accordingly.

Always budget – Regardless of whether you are a novice or more experienced bettor, stick to a budget, and don’t exceed it or it could lead to greater problems down the line.

Don’t overstretch yourself – Similar in many respects to the previous point, don’t be over-ambitious in the markets you play. Start with the ones you feel most comfortable with, such as the Moneyline, before expanding your horizons.

Follow your head, not your heart – Betting can be quite emotionally charged, so don’t follow your gut, but instead, spend time conducting your own research and make an informed decision on your wagers.
