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

Blacklist Cancel Icon

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.

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.

Bonus Description Find this bonus at
Deposit Match

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.

Bet Credits

A bet credit is money added to your account that can be used to make a bet but can’t be withdrawn.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.

Free Bet

A free bet works just like a bet credit where you're given money to wager with, but it can't be withdrawn.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!  

Risk-Free Bet

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.

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.

  • Do your research. Make sure you read a few of our betting site reviews so you know what’s out there before you make your choice. Be sure to check our blacklist as well if you’re considering a sportsbook that isn’t on our recommended list.

  • Read the bonus terms and conditions. Big bonuses are often best, but we have seen bonuses that are too good to be true. Be sure to check the rollover requirements before taking any sportsbook bonus.

  • Check the payout options and speed. Being able to get your winnings out in a timely manner should be one of the first things you look at when choosing a sportsbook.
