If there is one thing players love about BetUS, it's the fact that this offshore sportsbook is giving away amazing bonuses. At any given moment, there are at least a few lucrative deals, starting with the 125% bonus bundle (100% sportsbook bonus + 25% casino bonus) for new customers.

If you're still not sold on BetUS Sportsbook, now is the time to learn about its betting offer. This online sportsbook covers 20+ sports, including the most popular sports in America and some that might be flying under the radar of US-based bettors. We're talking about sports like cycling, handball, darts, and cricket.

Sign up with BetUS (Best sportsbook for niche sports)

Regarding the so-called niche sports, most sportsbooks cover only the most significant events. But not BetUS. This sportsbook goes beyond that! Its coverage of niche sports is nothing short of impressive, encompassing everything from major international competitions to local events. For example, you can bet on the Danish national league handball matches.

SportsBetting.ag - 50% Welcome Bonus Up to $1000

50% welcome bonus up to $1,000 on your first deposit
Another five bonus deals up for grabs
Fantastic selection of betting markets

This betting site belongs to the same family of offshore sportsbooks as BetOnline. Like its sister site, SportsBetting.ag has fantastic bonuses and a great selection of betting markets.

The first bonus you can claim on your SportsBetting.ag journey is the 50% welcome bonus up to $1,000, with a wagering requirement of 10x. You will get an even better deal if you use cryptocurrency for your first deposit. Fund your Sportsbetting.ag account with BTC, BCH, ETH, LTC, or DASH, and you'll qualify for the 100% welcome bonus up to $1,000, which has a wagering requirement of 14x.

Speaking of wagering requirements, there's one SportsBetting.ag bonus with a 6x rollover, making it very easy to clear. The deal is the 25% reload bonus up to $250, which you'll get every time you top up your account. In addition to those, this sportsbook also has a 35% crypto reload bonus, a 100% casino bonus, and a 100% poker bonus.

Sign up with SportsBetting.ag (Great bonuses, even greater betting offer!)

But Sportsbetting.ag is not just about bonuses and promos. This sportsbook also has a betting offer that can only be described as superb. More than 30 sports are covered, with several thousand events available for betting daily. The best thing is that almost every event covered by SportsBetting.ag comes with 20+ different betting markets.

Everygame - 100% Welcome Bonus Up to $750

Four welcome bonus deals to choose from
User-oriented business model
5,000+ games to bet on every day

Everygame has been around since 1996, attracting many Americans over the years. One of the main reasons why US bettors love this bookmaker is that it's incredibly user-friendly. Its user-oriented business philosophy is reflected in many things, starting with the Everygame website being straightforward to use.

Even though it covers 5,000 events daily, navigating this sportsbook isn't hard. It's because all games are categorized according to the sport, location, and competition. Further, the site is also very customizable, allowing you to choose from two languages (English and German), three odds formats (decimal, American, and fractional), and so on.

Because it's so easy to use, this betting platform is loved by newcomers. Another reason why they love it is that Everygame lets its new customers choose from four different welcome bonuses. The first deal is the 200% bonus up to $50 with an 8x rollover. The second deal is the 100% bonus up to $100 with a 6x wagering requirement. Everygame's third welcome bonus option is the 50% bonus up to $200 with a 4x.

The fourth sign-up bonus is reserved only for customers from the United States and Canada who use cryptos for their first deposit. If you belong to this category, you will get the following deal: – 50% up to $1,000 with an 8x wagering requirement.

MyBookie - 50% Welcome Bonus Up to $1000

50% sign-up bonus up to $1,000
Multiple currencies (and cryptocurrencies) supported
Wide range of sports and events covered

MyBookie.ag might not be ideal for high-rollers, but recreational bettors will love it. This sportsbook could be your perfect choice if fun rather than big stakes are on your mind. This isn't the place where you can wager hundreds of thousands of dollars on a single bet. The maximum amount you can deposit to your account in one go with a bank card is $2,500, while that number is $500 for Moneygram and Person2Person.

Instead of placing big bets, this sportsbook is ideal for aficionados who want to place smaller bets on attractive odds. And they really are attractive, especially if you bet on long shots. In fact, if you compare MyBookie.ag with its competitors, you'll see that it usually gives better odds on underdogs.

That said, we believe your chance of hitting big may be pretty good. Another way to potentially improve your chance of winning cash is to claim all the bonuses up for grabs at MyBookie.ag. Luckily, plenty of them are out there, starting with the welcome bonus.

Sign up with MyBookie.ag (Best sportsbook for recreational bettors)

There are two choices before you if you're a new MyBookie.ag customer - 50% welcome bonus up to $1,000 with a 10x rollover and a 10% welcome bonus up to $200 with a 1x rollover. The first one will bring more money your way, but the latter option is significantly easier to clear.

XBet - 100% Welcome Bonus Up to $500

100% up to $500 bonus for new customers
Boosted odds for specific events
Racebook for greyhound and horse racing betting

XBet.ag is a sister site to MyBookie.ag and the two share many similarities. We trust both are reliable and easy to use, with plenty of betting markets at the players' disposal. These two sportsbooks do have their differences. For instance, XBet.ag has only one welcome bonus deal. But the deal is fantastic!

XBet.ag is giving away a 100% match-deposit bonus for new customers, with maximum bonus credits equal to $500 and a wagering requirement of five times to turn them into withdrawable cash. You can use them to bet on some of the over 3,000 sports events covered by XBet.ag every day.

Apart from sports, this betting site also covers politics, entertainment, and eSports. On top of everything, XBet.ag has a special section dedicated to greyhound/horse racing betting. Its racebook covers almost every major racing event in the world, meaning you can be on dozens of races daily.

Sign up with XBet.ag (Best sportsbook for dog/horse racing fans)

We still haven't told you the best thing about XBet.ag. This offshore sportsbook stands out from the crowd with its odds. They are incredibly lucrative from a bettor's point of view, and XBet.ag sometimes makes them even more lucrative. What we're talking about is the XBet.ag odds booster - the sportsbook sometimes gives much better prices on popular bets.

BUSR - 100% Welcome Bonus Up to $1500

100% Sports Free Play Bonus
Enter the code SPORTS100FP
20x rollover requirement

If you're looking for a beginner-friendly betting site, BUSR is one of the best bookies around. The moment we visited the homepage for the first time, we were impressed with how clean and well-developed the UI is. Even pros will appreciate it, as it takes just a couple of clicks to get back into the action.

Overall, we'd say their bread and butter is horse racing, along with NFL games and European soccer. But after monitoring the BUSR sportsbook for a while, we noticed they're pretty consistent and versatile. The odds aren't half bad, either, especially when you consider how early they're posted on the site.

Sign up with BUSR (Best sportsbook for politics, props and early odds)

Another thing we liked is the presence of politics and eSports markets. Unlike most self-claimed versatile bookies, BUSR actually covers gubernatorial primaries and other kinds of smaller elections. Aside from the welcome bonus, you can also get up to $1,000 for horse racing, as well as $250 for each friend you refer.

Bookmaker - 25% up to $500

$500 crypto welcome bonus
Rollover requirement is only 8x
Fiat options available, too

They say Bookmaker turns sports betting into science but stays true to the roots. And we have to say - those claims are definitely true. The bookie's motto is Old School Meets New School, after all. Live betting seems to be their calling card, with extensive options for NBA and MLB Playoff games. Now that's what we call knowing the US audience. At all times, there are 100+ lines with drastically reduced juice.

In addition, we were infatuated with the mobile website. It's much more modern than the desktop version and offers awesome data visualization at your fingertips. This comes in handy if you want to dig into Bookmaker's extensive collection of futures and props. Sometimes, they even go as deep as offering O/U bets on point guard rebounds, which is unheard of nowadays.

Sign up with Bookmaker (Best sportsbook for futures)

And even though reload bonuses are relatively common, we love Bookmaker's twist on them. Depending on your VIP level, you'll get cashbacks at different rates. It starts at 10% and can go up to 10%. They might also have the most lucrative referral program on this list, with $500 awarded per person.

BetNow - 200% up to $200

4 different welcome bonuses - from $200 to $1,000
Rollover requirement is 20x for all four
Just enter one of the bonus codes, and you're good to go

Most of the time, we're not the biggest fans of specialized bookmakers. However, BetNow is one of a kind, for the most part. The brand specializes in basketball but actually provides outstanding lines and coverage for hockey, football and the MLB. Still, hoops reign supreme, with over 20+ leagues from all over the world getting early lines and lots of bet types per event.

We like how simple the interface is, especially when we're placing in-play bets. You can see the lines moving in real time with easy-to-access features throughout this online sportsbook. Props are always on hand, whereas other bookies require you to dig around before finding them.

Sign up with BetNow (Best sportsbook for NBA betting)

If you like the welcome bonus, then we believe you'll love the other promos. Throughout our review process, there were always at least 2-3 tournaments active. Most of them were for MLB and NBA, covering long periods, but we've also seen a decent number of mini promos, referral deals and those kinds of perks.

How We Review Our Sportsbooks

There are thousands of online betting sites, but not all deserve your trust. We believe that only a handful of sportsbooks fulfill all the requirements to be called the best. We've analyzed eight such sites, and you can check out our reviews in the previous section.

Each sportsbook with our stamp of approval is a great choice, but you need to weigh your options to see which one's ideal. Once you've figured that out, just go to the official site of that sportsbook and follow the on-screen instructions to create your account.

It shouldn't take too much of your time. The whole process should last no longer than only a couple of minutes.

Now, with your account up and running, it's time to make a deposit and start betting for real money!

Of course, you don't have to stick to just one sportsbook. You can create accounts at as many online betting sites as you wish. This way, you can take advantage of multiple bonuses and shop for the best odds or betting markets.

Essential Tips for New Bettors

The most important thing to remember when starting your online betting adventure is that the whole point of it is to have fun. This way, you will not feel too bad even if you lose. After all, it was nice while it lasted.

But no one likes losing. That's a fact. And it's why you need to do all in your power to improve your chance of winning. The easiest method is to stick to the favorites.

Unfortunately, you're not the only one who knows this. Oddsmakers also know it, so they usually offer very short odds on the favorites likely to win. Still, you must remember that some sportsbooks are reasonably priced, even on major favorites. All ten betting sites we've reviewed belong in this category.

Finding better odds is essential for sports bettors. To do that, you need to research your bets, figuring out whether there's value in specific markets. You must check team/player stats, recent streaks, injury news, etc. It's not an easy job, but it can be very rewarding.

Sports Betting Types

Let's experiment - go to one of our recommended sportsbooks and click on any random event. You'll notice dozens (if not hundreds!) of bets for that match. It seems a lot, but all those can be placed into three categories - game betting, props, and futures.

The first category is game betting, the umbrella term for moneyline, spread, and over/under bets. You can find these betting types in almost 100% of sportsbooks. Betting the moneyline means betting on the winner of the match. Spread refers to bets in which the favorite is given a point handicap, so the chance it will win is roughly 50%. Finally, over/under is a bet on whether the total number of points will be higher or lower than the number set by the sportsbook.

More exotic in-game bets (e.g., a player scoring over 30 points) are called props. Most focus on what's happening in the game, but some have nothing to do with it. For example, for some Super Bowl props you need to guess the Gatorade color or the length of the halftime show.

Some online sportsbooks also offer future bets or futures. Those are wagers placed on events whose outcome won't be known anytime soon. Some good examples include betting on the following year's Super Bowl winner, the next FIFA World Cup, etc.

How We Review Our Sportsbooks

You must invest much time and energy into the research to find an excellent online sportsbook. Or, you can just trust our judgment! We have done the hard work for you, digging deep into every site to examine the user experience, compare the betting odds, analyze promo offers, and more.

We were able to pick out a couple of sports betting sites that tick all the boxes. All that's left for you is to read our reviews and decide which sportsbook is your ideal pick. Each is special in its own right, so it's up to you to see which one suits your gaming needs and wishes the best.

What do we think is the best?

We love all of them, so we recommend creating an account on each platform.
