State betting guides
Covers has been providing Americans with independent sportsbook reviews for over 25 years. As legal sports betting rolls out at the state level across the USA, it’s important we deliver localized guides so that you can make informed decisions based on information relevant to your area.
Whether you’re looking for the best sportsbook with the best NFL odds or the betting site with the most in-play markets for the NBA, we’ve assembled a list of the most trusted betting sites in your area:
How we rate and review sportsbooks
Covers has been rating sportsbooks for over 25 years. This experience has led us to develop the Covers BetSmart System™ to ensure that you’re betting at a safe and legit betting site. The main factors that go into a sportsbook’s overall rating are bonuses and promotions, banking and payout speeds, key features, security and trust, and customer support.
Of course, there are many other factors we look at as well as we strive to give you all the information you should know about every sportsbook we recommend. That’s why our team spends a few days at each sportsbook before submitting their reviews. They deposit, they collect bonuses, they place bets, and they withdraw — all so that you’re getting the most in-depth sportsbook reviews on the internet.
Blacklisted sportsbooks
Covers takes pride in being the most trusted site for sports betting information and we want you to have the best experience wagering at safe betting sites. So when a sportsbook doesn’t meet our standards, or when we get multiple reports of bad practices from our users, they end up on our blacklist.
- Allegations of withdrawal issues
- No license information available on site
- Poor customer service
- Multiple reports of slow payments
- Allegations of non-payments
- Risk of account closure simply for winning bets
- Reports of confiscated winnings
- Slow customer support response times
To see which online sportsbooks you should avoid or to report a sportsbook, check out our blacklist page.
Bonuses, free bets and promotions
As regulated online sports betting spreads across the US, sportsbooks are doing all they can to attract users and that usually starts by offering a juicy welcome offer. But not all bonuses are created the same. Deposit matches, bet credits, free bets, and risk-free bets are different ways that betting sites are enticing gamblers to make a deposit. These offers can be a great way to build a bankroll but it’s important that you understand each one so that you can choose the offer that is right for you. Be sure to read the terms and conditions of the bonus before claiming it.
These are the most popular bonuses awarded by sportsbooks. They are usually given at first deposit as a percentage of your first deposit. For example, get a 100% deposit match bonus up to $200.
A bet credit is money added to your account that can be used to make a bet but can’t be withdrawn. You can, of course, withdraw any winnings made from bet credits.
A free bet works just like a bet credit where you’re given money to wager with, but it can’t be withdrawn. Any winnings from a free bet are yours to keep, of course! Some sportsbooks will offer free bets just for signing up — no deposit required!
A risk-free bet works exactly how it sounds. If you win your risk-free wager, you keep the winnings just like any other bet. But if you lose the risk-free bet, the sportsbook will refund your stake up to the amount specified by the promotion.
Best sports to bet on in the US
It will come as no surprise that the “Big Six” leagues in North America are the most heavily bet on by Americans, but we’re also starting to see soccer become more popular with the rise of MLS.
The NFL remains the most popular sport to bet on. With more fans tackling NFL odds every Sunday, the best football betting sites know NFL gambling is all about options. The best ones offer early opening odds and a menu of markets, from game lines to player props.
Notable star athletes and near-nightly action fuels the NBA betting markets, but there’s more to NBA betting than spreads and totals. The most trusted basketball betting sites post team and player props as well as live betting options.
There’s no better way to show your school spirit than betting on college basketball. And there’s no better time to bet on college hoops than March Madness. While the college basketball season runs from the fall to the spring, the action really heats up for the NCAA Tournament — one of the best sports betting events of the entire year.
Saturdays belong to college football betting. The top programs in the country battle for a shot at the CFP National Championship, with heated rivalries, marquee matchups, and stunning upsets along the way. College football is one of the most popular sports and the best online betting sites back that up with multiple ways to wager on NCAA football.
Betting on the MLB reigns supreme in the summer months and gives sports fans a drama-packed postseason in the fall. What more could you ask for? How about endless ways to wager on those games at US sportsbooks. The MLB odds have multiple methods to make money, from run lines and totals to five-inning odds and in-play betting.
Betting on the NHL has it all: Speed, hits, scoring, and a ton of odds to cash in on. The most trusted hockey betting sites won’t leave you out in the cold when it comes to NHL odds and gambling options.
Soccer betting is one of the fastest-growing markets at US sportsbooks. From the English Premier League to the MLS, the “beautiful game” is catching on with bettors. The most trusted soccer betting sites offer aggressive bonuses and strong odds.
Golf betting is one of the fastest rising gambling markets in the USA. With tournaments taking place every weekend, there are always great odds to bet into. The best golf betting sites should offer multiple markets and a robust live betting section.
Tips for choosing a sportsbook
- Know what you want in an online betting site. Think about your betting profile before anything else. What sports and leagues do you bet on? Do you need lots of options for props and derivatives? Do you usually bet on mobile or desktop? Knowing the answers to these types of questions will help you narrow down your sportsbook list.
