Rating online sportsbooks is difficult and there is no secret formula that works for all sportsbooks. First and foremost, when betting on sports you want to know you'll be paid. But that's not the only criteria for grading sportsbooks. We need to factor in odds (commission), lines, bonuses and other promotions, customer service, the website, banking options, and so on.

So grading sportsbooks is a subjective thing, and the ratings would certainly change if your criteria was different or more selective. That's why you can use our free sportsbook recommendation tool if you want a little extra help.

Make sure you check back often as our ratings do change and we are adding new sportsbooks all the time. If you join our email list you'll always be up to date.
