Top or Flop: The 10 Criteria for Top Online Gambling Sites

With hundreds of online gambling companies in the industry, it can be difficult to choose which one to trust with your money and where to spend your leisure hours. Our staff spent many hours solving this very issue so that you don’t have to as we rated every casino site for 10 different important criteria. Here is a list of the rating criteria we used in our review process:

Games & Software: The Quality of Games

Online casinos offer so many different game types and titles that there is no reason to play at sites that have a limited selection. Our reviewers made sure to check each casino’s game portfolio and find out how many games are on offer, which software providers made them and what types of gambling players can enjoy.

Live Casino & Dealer: Playing with Real Dealers

Live dealer games have become exceedingly popular in recent years, with most major casino platforms introducing at least some live table games like roulette, blackjack or poker. We rated the live casino games on each site to make sure we give you the full picture of each operator’s offer in this area.

Mobile Casino: The Portable Fun

Mobile devices are taking up more and more of our time on a daily basis and much of the online gambling done nowadays happens on mobile phones and tablets. We examined the mobile casino platforms of the various operators and checked for both downloadable and instant play options at each site.

Welcome Bonus & Promotions: Free Cash and More

Bonuses are one of the key reasons for players to sign up with online casinos, which is why we considered bonuses, free spins and other promotions as key elements of a casino rating. This category reflects the operator’s generosity in handing out free cash to its players.

Customer Service: Getting in Touch

When time comes to get in touch with your operator, the choice of contact methods and the quality of customer service can be quite important. We consider the customer service quality as one of the key elements of any online casino and we rated online gambling sites with this criteria in mind.

Payment Options: How Can I Deposit?

Another important choice that every player has to make when signing up with a new site is how to make deposits and cashouts from that site. The casinos that offer plenty of deposit and withdrawal options rank higher in our casino ratings, since they allow more players to enjoy the games the way they like to.

Limits & RTP: The Right Casino for You

Not every online casino is made for all the players out there and the minimum and maximum deposit, cashout and bet options can often be very important factors in picking a site to play at. Our staff went over such elements as well as the overall return to player of every site in order to help players find the sites at which they can play at their preferred stakes.

Usability: Using the Platform

Casino platforms can be so much fun to play at, but the ones that don’t offer sufficient usability simply aren’t. We made sure to rate highly the sites that offer easy navigation, intuitive layout and fast loading times. This category is all about the general ease of use of every site on both desktop and mobile devices.

Security: Keeping You Safe

Staying safe while gambling online is one of the key challenges players are faced with. To help with this, we made sure to tell you all about the licenses every casino operates under, their safety protocols and the ways they keep your money safe. If there is anything shady about a casino, we will make sure to tell you before you sign up.

Additional Offers: More Gambling Types

Casino games are not the only ones offered at many of the online operators we review, which is why we made sure to also test their other products. Sports betting, fantasy sports, poker and bingo all fall into this category. If you are looking to bet on any of these games, find out what options are available right here.

Legality of Online Gambling in the US

While the rest of the world has been enjoying in internet based casinos for many years, online gambling in the US has only been legal for a short time. Nowadays, each state gets to regulate its own online gambling market, with a growing number of states finally issuing bills that make existence of online casinos possible.

Before such laws were put into place, American players could only gamble at illegal offshore platforms which allowed US players to sign up despite not being licensed to do so. Such offshore sites were not safe to play at and players often ended up without their deposits and winnings.

With the online gambling market finally getting regulated in the USA, players now get to play at licensed and regulated sites for the first time in their history. If you live inside the USA, WinPower helps you find sites that you can play at by providing you an option to filter our casino comparisons and show only sites legal in your state.

Online vs. Offline: Where to Play

Americans can now finally legally play online casino games, but the option to play the same games in live casinos has been around for decades. Places like Atlantic City feature some of the biggest brick and mortar casinos in the world, with games like blackjack, video slots and video poker well known to American public.

The question of which is better, live or online casinos, is one that has been asked by many players in the US and abroad. The answer to that question is not quite simple as different types of players have different preferences.

Live casinos bring a certain element of socialization that online casinos can hardly match. If you love casino games for the hustle and bustle of the casino floor, like meeting new people and enjoy the atmosphere of large open space of the casinos, than offline venues are best for you.

Check it out now or sign up with one of the top rated internet gambling sites in order to claim massive bonuses and enjoy the online gaming atmosphere from the comfort of your home.

Currently, only players in some American states get to play online casino games for real money at legal sites. Of course, there is still the possibility of playing at offshore casinos which accept just about anyone, but the dangers of doing so are simply too great.

Offshore casinos, by definition, are sites that operate from offshore locations and with practically no license to speak of. Being unlicensed and unsupervised, these sites are notorious for offering sub-par service and often being fraudulent altogether.

While licensed American casinos are supervised by regulatory agencies and obligated by law to pay their players at any time, offshore casinos are not obligated to do anything. In fact, every time one sends a deposit to such a site, they are only hoping the company on the other side will pay them back when the time comes.

Finally, playing at offshore sites can even get US players into troubles with the law, as financial transactions to such sites are hard to make. Since no US bank will help you transfer funds to an offshore gambling site, your options are limited and can often be legally questionable. For all of these reasons, make sure to keep playing with legal sites only and avoid offshore sites by all means.

Checklist: Registration

Now that you know what online sites are legal and how you can sign up with them, it is time to choose a site to register with. Before you make your final decision, use this checklist and make sure that the site in question complies with all the points on it, so you get the best gaming experience possible:
