Top or Flop: Our 10 Criteria for Sports Betting Sites
Finding the best site is not something you can do in a minute, but with our help, the process can be much faster. We have categorized the operator’s performance into 10 important categories and we have rated every site in each of the 10 categories. These are the things we looked at while rating the best betting sites in the USA:
Betting Offer & Odds: The Betting Portfolio
A key element of any sportsbetting site is the offer of different sports and markets that players can place wagers on. What’s even more important, we rated the quality of the odds at every site, including live betting odds and pre-match odds. We compared odds across the sites to find out which bookies offer the best price.

In-Play Betting: For Modern Bettors
In-play betting has taken over a decent part of the market, as more and more punters are placing money on ongoing matches hoping to capitalize on good odds and ever changing nature of games in sports like football, basketball and others. We looked at the availability of live betting markets and the prices for in-play match betting.
Mobile Betting: Mobile Apps and Platforms
Mobile betting is becoming more important by the day, since so many people now use their phones and tablets to access the internet more than their computers. We took a look at the operators’ mobile apps and platforms and found out how well one can bet on the go at each site and what kind of offer is available in mobile versions.
Welcome Bonus & Promotions: More Cash to Bet With
The more cash you have to bet with, the better the odds you will win money. With bonuses and promotions offered by many of the top rated betting sites out there, your odds are definitely improved quite a bit. We rated both the welcome offers and the ongoing promotions at every site and came up with conclusive ratings for which sites provide the most added value.
Customer Service: Getting the Help you need
Our betting sites reviews also took a good look at the customer support departments of the operators in question. The most helpful agents earned their operators the best ratings.
Payment Options: Moving the Cash
Few things are as important when it comes to online betting as actually getting the money into your account and making a withdrawal in a fast and timely manner. We tested which payment methods and currencies (dollar or bitcoin) are available at each site, how fast the deposits and cashouts are processed and what fees apply to each deposit and withdrawal request.
Limits & RTP: What You Stand to Win
The overall return to player is a key component of any sports betting site and we looked at how sites build their odds and what kind of RTP rates are offered. We also tackled minimum and maximum deposits, cashouts and bets in various sports as well as what kind of maximum winnings you can expect and how much you can cash out in a week or a month if you do win big.
Usability: Interface & Navigation
Yet another element we considered in our online sports betting reviews, the quality of the actual platform is also important. This includes the way the site looks and feels while you are using it, the colors and the design of the site and the navigation options. The easier and more natural the site is to use, the higher the usability rating.
Security: Keeping You Safe
Safety is a big part of having a good online experience no matter what you are doing. Since there are many people out there who would gladly get their hands on your banking and personal information, playing at sites that take player security seriously is imperative. We rated security based on the safety protocols used by the operators to keep all your stuff private and safe.
Additional Offers: More Options
Gambling does not only include sports betting and many users surely know it as they enjoy playing casino games, poker, fantasy sports or even bingo. If you fall into any of these categories of gamblers, than playing at sites that offer additional products on top of their platform will always be a good idea.
Legality of Online Sports Betting in the USA
It may seem strange that there is any doubt about the legality of online sports betting in the USA, but it has only been a short time since first fully licensed sites were even open in the country. Before, the only sites one could bet with were those with no license whatsoever, often referred to as offshore betting sites, due to operating from foreign offshore locations.
Offshore sites were always very dangerous, as such operators never really cared about their customers and were more than happy to accept American players without being able to guarantee their safety or payouts in cases of big wins.
Legal sports betting is now finally possible and American players from many states can start playing at sites that have an actual license, issued by their state regulator. However, it is very important to know which states this is actually possible in and which bookies can be played with from which state.
States with legal Sportsbooks
Online or Offline? Check Out the Online Sports Betting Reviews
Sports betting is now possible both online and offline for players in many American states and this has created a dilemma for many players. While both options are available, deciding which one is better is not an easy task.
However, for many reasons, we believe that online betting sites offer more than offline stores. Due to a difference in operating costs, online bookmakers are in fact able to offer more to their customers, including better odds, a wider choice of bets and markets and a generally more appealing offer.
The best online bookmakers also provide bonus money and free bets for their players, which provides an opportunity for players to experience real money sports betting without the need to put up all of the money. A player who makes a deposit with an online bookmaker will almost always receive extra cash or a free bet opportunity that would not be available to a player in a live betting environment.
The fact is that every person now gets to choose how to bet, and despite all the advantages of online betting, those who prefer to do things in person still can. For the rest of us, online betting has opened a fantastic opportunity to place pre-match and in-play bets from the comfort of our homes or on the go at any time and in any place.
What to Look for Before Registration
If you are ready to start betting sports online, there are many things to consider in choosing a site to bet with. You can choose your site based on a number of important criteria, and you get to decide how important each of them is to you. Some of the most important things we believe you should consider include:
- Versatility of the portfolio
- Betting markets offered
- Betting odds quality
- Customer support options
- Payment options
- Cashout speed and reliability
- Licenses in your state
- The safety protocols used
- Live betting platform
- Mobile apps and platform

Sport Betting Review Tips & Tricks
If online sports betting is new to you, then there are many things to take into consideration and be careful of. We have compiled a short list of the top tips and tricks to keep in mind when it comes to betting online, which we also considered while compiling our sports betting reviews. Apart from these tips, make sure to also check out our betting guide for even more instructions on how to use online betting sites in the best possible way.
- Play at licensed sites: The first and most important tip we can give you is to always play at licensed sites only and avoid all offshore or unregulated operators by miles.
- Ease into it: There is no reason why you would have to start out with big bets. If you are new to online betting start with some small bets and gradually build your way up to where you want to be.
- Bet at the best prices: Different bookies can offer a different price on certain events. Make sure you always bet at the best odds available, even if it means having to sign up with a new bookmaker.
- Bet your favorite sports: Going off and betting on a sport you barely have any idea about is not smart. Stay within your comfort zone and bet the sports you know and love.
- Bet on your phone: The mobile betting options are more available by the day and betting on the go is a great way to bet in the moment and at the best price. Install an app on your phone to give yourself this option.
- Use all promotions: Online betting is so great because of all the promotions and bonuses players get to use. Don’t miss out on them and use every promotion you can get your hands on.
- Take advice: Whether you take it from WinPower or your more experienced betting buddies, it is important to take advice from those with more experience, so don’t be shy about it.
- Star responsible: One last thing to remember is to stay responsible and gamble only the money you can afford to lose. Don’t let a hobby become a problem and stay smart at all times!
Questions players ask
Why should I use betting site reviews?
Betting site reviews offered at WinPower are designed to help you get to know various betting sites before you actually sign up. They are a great way to avoid bad sites and play only with the best, so there is no reason not to use them.
Are the betting site reviews biased?
No! We make sure to create every review in a completely objective and unbiased fashion and we do not get paid to write reviews. Every betting site described at WinPower was tested by our staff and rated based on merit alone and no other factors.
Who can legally bet online in America?
All players who are aged at least 21 and who live in states where online gambling is licensed can bet online. However, it is important to also bet at the right sites, as not every site has a license in every state. Before betting, make sure you do your research and find sites that are licensed in your state.
Why should I not bet at offshore sites?
Offshore betting sites are not safe to play at as they have no legal obligation to keep your information safe and they have historically not done a good job of making sure their players are safe or paying the winnings. We recommend staying well away from any site that is not licensed in your state.
Can I bet on my mobile phone?
Yes! All the top sports betting operators in the USA offer a mobile betting option, whether it is through a downloadable betting app or an instant play betting platform available through the internet browser. Check out our top betting apps to find out where you will get the best mobile betting experience.
What payment methods can I use?
In order to deposit or cash out from a betting site, you can use a variety of payment methods. These include PayPal, Skrill, ACH, PayNearMe and of course all the popular credit and debit cards. Deposits are instant and free at the best sites, while a cashout may take a few days to process.
What are sports betting bonuses?
Bonuses are promotions issued by the betting operators to promote their sites. Bonuses add cash or free bets to your balance and are a great way to build up your bankroll. You can claim bonuses at various top betting sites and get lots of extra value this way.
Can I claim the same bonus many times?
No! Most betting bonuses are restricted to a single offer to a single player. Trying to avoid this rule by making multiple accounts will get your accounts banned and your funds confiscated, so make sure you adhere to the rules and only have one account on every betting site.
Do I have to verify my identity?
Yes! When betting online, you will have to confirm you are who you claim you are by sending in scans or pictures of your personal documents to the operators. However, this process is perfectly safe and when playing at licensed sites you can be 100% sure that your ID will remain private and not shared with anyone.
Do I need to pay taxes on winnings?
Yes! If you win money while betting sports online, you will have to pay your taxes. Once you make a withdrawal into your bank account, remember not to forget this money on your tax report and make sure to pay every cent so as not to get into trouble with the law.
