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.

Benefits of Gambling Online


Perhaps you live in an area miles away from a gambling mecca like Las Vegas, or even just your nearest casino. Maybe you live in a country where land-based gambling isn't even available. The truth is that in most places, big land-based casinos 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 you won't find in a live setting. After all, how many brick 'n mortar casinos near you offer hundreds of slot and table games with low stakes that cater to casual gamblers?

A Better Range of Games:

This is where gambling online really comes into its own. You can choose from a huge selection of games and try many titles 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. All you have to do is log into your favorite casino website to play hundreds of slots games, craps, baccarat, video poker, blackjack, roulette, faro, keno, and more.

Big Bonuses:

Online gambling rooms offer lucrative welcome bonuses to new players. These bonuses give you hundreds of dollars, pounds or Euros in free cash just for playing your favorite games. You may even get some free spins on the latest slot, which is a great way of earning real money without spending a penny.

Great Security:

All online casinos 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.

Frequently Asked Questions


What is Online Gambling?

Online gambling is playing risk-based games over the internet in the hopes of winning more than you lose from them. This can include things like slot machines, table games or video poker.

How Popular Is Online Gambling?

Huge. The global online gambling market is worth billions of dollars and is continuing to grow. It's expected to be worth almost $60 billion by 2020.

Which Sports Can I Bet On?

Sports betting sites are licensed in the same way as online casinos. Gamblers can place bets on hundreds of markets on sports as diverse as football/soccer, basketball, and ice hockey. The best sports betting websites even have live betting where you can place wagers on matches as they are in progress.

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?

How do I quit gambling?

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.
