    How we Rate the Top Online Gambling Sites


    Background Check

    We go through a 25-step review process for each and every casino we recommend, starting by ensuring that they have a proper license from a respected jurisdiction. The best sites are licensed in places like Malta, Gibraltar, Alderney, or the UK. We also like to know that every casino site is secure and has fully encrypted software using SSL. Finally, we perform a background check on the company to see where it's registered and investigate their online presence.

    Background and Safety Check

    We deposit funds and contact customer support

    A key factor in our casino reviews is the ease of making a deposit for real money play. We want to ensure that each casino site we recommend has a variety of deposit methods and it is easy to deposit funds there. In this step, we also contact the customer support service of the site. We want to know for our own peace of mind that they respond quickly and have the answers to some key industry questions that we ask.

    Deposit and Contact Customer Support

    Play, Win, Cash Out

    From there, it's important that we experience exactly what the customer experiences. We look for sites with a good game selection, and play a variety of slots and table games on desktop and mobile, making use of the available bonus offers. Welcome bonuses are a big draw for online casinos, and we look for the most generous ones with the best wagering requirements. We aim to win on as many games as possible and then cash out, seeing how quick and easy it is to withdraw our funds, as well as how long it takes for the money to reflect in a selection of bank accounts and e-wallets.

    Game Winnings

    We rate and then approve

    In the final step of our review process, we carefully score the online casino on the above criteria and then write a detailed review about our findings and score individual sections of each casino. We then put them on our site in a list and display both the positive and negative points on each review along with important information you'll need to know.We have an ever-changing list of top casinos as well as blacklisted casinos that we check and review every 3 months so that everything is kept up to date.

    4.2 /5

    The latest gambling sites on our blacklist

    Our 25-step review process is carefully designed to make sure every casino we recommend is of the highest quality. We look at data protection and regulation, bonus terms and conditions, game variety and progressive jackpots. You can check out all the casinos that failed to make the grade right here on our blacklist.


    Benefits of Gambling Online


    Whether you live miles from Las Vegas, or even your nearest casino or bookmaker, the truth is most land-based casinos and sportsbooks can't compete with what online casinos and gambling sites have to offer. Internet gambling can provide hassle-free sign-ups, super-quick banking and a choice of games and sports betting opportunities you won't find in a live setting.

    A Larger Variety of Gambling Options

    Gambling online offers a huge selection of games that you can try out for free first. Lots of casinos even have sportsbooks, bingo and poker rooms attached. Funds can easily be transferred from one tab to another, giving real-money players in the USA even more choice. Simply log into your preferred casino or sports betting website to play hundreds of slots games, craps, blackjack and roulette, or have a bet on the big football match or UFC fight.

    Big Bonuses and Free Bets

    Online gambling sites offer lucrative welcome bonuses to new players. These bonuses give you hundreds of dollars, pounds or Euros in free cash in return for choosing them as your number one casino or bookmaker. You may get free spins on the latest slot, or free bets to use on specific sports events, which are great ways of earning real money with minimal risk.

    Great Security

    All online casinos and sportsbooks abide by the strictest security standards. Regulated online gambling sites use industry-standard 128-bit or higher encryption to protect players. They also have independent auditors in place to test the software before it hits the market. Auditors make sure that a casino site's payouts are accurate on a regular basis.

    Convenience

    Players across the globe can log in to a gaming account from their mobile device and access the best in sportsbooks, table games and slots. This means you can play for real money at a time and place to suit your needs. All the sites we recommend have optimised their mobile gaming experiences, so check out our shortlist and download the top gambling app for your smartphone, whether you’re playing on iPhone, iPad or Android.

    Our Real Money Online Gambling Tips for Players

    To ensure you get the most out of your real-money casino gaming, we asked our expert reviewers for six top tips…


    • 1

      Use a trusted USA site

      Don't hand over a Euro, pound or dollar until you've established that you're on a licensed casino site that is independently audited to provide fair games, and which meets all of the industry standards for quality.

    • 2

      Boost your bankroll with a bonus

      Kick-start your gaming with some extra cash. It will make your money go further and give you a bigger sum to start with.

      Pick the games you love

      Whether it's poker, roulette, blackjack, baccarat, or slots, make sure your money goes towards your favourite games. It's important to shop around for the sites with the best choices available before you start laying down your own money.

    • 4

      Choose the best payment options

However, there may also be some form of ID verification process before a withdrawal is authorised.

    • 5

    Frequently Asked Questions


    What is online gambling?

    Online gambling is the process of playing casino games or betting on sports events on the internet. The aim is to win more money than you lose. Online casino gambling includes slot machines, table games and video poker. Online sports gambling involves wagering on the outcome of any sports event where betting is available.

    Which sports can I bet on?

    Sports betting sites are licensed in the same way as online casinos, and gamblers can place bets on hundreds of sports. The sports you can bet on range from more traditional ones like horse racing and football through to up-and-coming ones including Esports and UFC. The best sportsbooks and bookmakers even have live betting, where you can place wagers while the events are in progress.

    How popular is online gambling?

    Online gambling is hugely popular. The global online gambling market is worth billions of dollars and continues to grow every year.

    Can I gamble on my mobile device?

    Yes. Most casinos, poker sites and sports gambling sites offer apps for Android or iOS phones. In many cases, however, you can simply log in via your mobile web browser to access games.

    Can I gamble for free?

    Yes. The good news is that most (if not all) online casinos offer free-play options alongside their real-money games. In some cases, you don't even need to register an account. Just open the casino and try some games for nothing.

    Will I get a welcome bonus?

    Yes. Most casinos, poker sites and sportsbooks offer players some free cash when they join up. This can range from a simple deposit bonus to free slots spins, or even a little cash with no strings attached. You gamble the cash, and all winnings you make are yours to keep.

    Is it safe to gamble online?

    Yes. On the whole, most online casinos are safe to play at, however, there are unfortunately some that don't always play by the rules. When looking for a safe site, ensure that it has a license, particularly from a reputable regulatory authority, uses encryption to protect your data, and offers trusted banking methods. If you are unsure about where to go, take a look at our top list, where all of our recommended sites have trusted reputations and offer the highest levels of security to players.

    What kind of games do they have at online casinos?

    Online casinos are packed with all the games you'll find in any land casino. Take your pick from slots, roulette, blackjack, poker and many other favourites and pick your stakes from just a few cents to $500 a spin. You can even enjoy gambling online against a human croupier with 'Live Dealer' games. Take on a human dealer via a webcam and even chat to them in real time!

    Can online casinos scam you?

    Yes, there are some low quality online casinos that may cheat you out of money by manipulating the games, or not paying out money once you've amassed a considerable balance. The more reputable casinos go through a rigorous testing process and abide by certain fair play rules in order to maintain a trusted reputation, and earn their profit from the house edge that they enjoy. They'll win more than they lose over time because of that edge, even if they lose over the short-term to a few players. That's why we only recommend sites that are trusted, safe and secure.

    What are the best online gambling sites?

You can look into measures such as capping your deposit amounts, setting up ‘Reality Check’ (a popup timer asking if you still want to play while logged in) or setting up a self-ban to exclude your account from certain services for a period of time.

    If you're struggling with your gambling habits and finding it hard to recover from a big gambling loss, it could be the signs of a gambling addiction. We strongly recommend that you seek professional medical help, check out our gambling addiction help page for more information.

    What is the best gambling game to win money?

    Blackjack is commonly known as the casino game with the best odds for you to win. However, this requires a basic understanding of the game. You can learn how to play blackjack and get top secret blackjack tips from our experts on our Blackjack site.

    Which online casino has the best payouts?
