How we rate the top online gambling sites
Every online gambling site goes through our 25-step review process. Below is a snapshot of our criteria for ranking gambling operators.
Safety and security
We start by ensuring that the site has a proper license from a respected jurisdiction. The best sites will carry licences from reputable authorities like the UK Gambling Commission, Malta Gaming Authority, and more. We also like to know that every casino site is secure and has fully encrypted software using SSL. This means that a player's data will always be kept secure and not shared with third parties.
Games and software
A top online gambling site will offer a range of new and classic casino games. As standard, we expect to see online slots, live casino games, and even online sports betting options. In general, we look for over 750+ casino games, though the very best gambling sites will feature over 1,000 titles to choose from. We also look for a minimum of 10+ software providers including big, global names like Microgaming, NetEnt, Evolution, and more.
Banking and payments
A top gambling site will offer quick and easy casino payments. Most gaming platforms will have a range of deposit options including Visa, Mastercard, PayPal, e-wallets, and more. In our opinion, the best sites will offer 10+ payment choices, all with reasonable deposit and cashout limits. High limits should cover around ￥5,000 and processing times should be less than 24 hours.
Bonuses and promotions
No gaming site is complete without a range of casino bonuses and promotions. We look for welcome bonuses (typically deposit bonuses) that are generous and that have fair wagering requirements. We look at industry averages and only recommend justified welcome offers. In addition, we investigate the range of promotions for existing players including free spins, VIP schemes, bonus bets, rewards, and more.
App and mobile casino
Nowadays, any top online casino operator needs to work on mobile. We look for sites that function seamlessly in a mobile browser. We like to see popular casino games are optimized for mobile, and that 90% of all desktop games are available on the mobile casino. Bonus points go to the brands that have a dedicated gambling app which is regularly updated for iOS and Android. In our casino reviews, we also like additional extras such as mobile-accessible live chats or even app-specific bonuses.
Best gambling apps and mobile sites
Around the world, you'll find most top gambling websites will be fully accessible on mobile devices. Top online casino sites have built some of the best gambling apps around that include highly unique features. You'll commonly find two-factor security, unique mobile bonuses, plus app-exclusive casino games. Below are just a handful of some of our best gambling apps for 2024.
Benefits of gambling online
Whether you live miles from Las Vegas, or even your nearest casino, the truth is most 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 that 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 bingo and poker rooms attached. Funds can easily be transferred from one tab to another, giving real-money players in Japan even more choice. Simply log into your preferred casino website to play hundreds of slots games, craps, blackjack and roulette.
Big bonuses and free bets
Online gambling sites offer lucrative welcome bonuses to new players. These bonuses give you huge amounts free cash in return for choosing them as your number one casino. You may get free spins on the latest slot, which is a great way of earning real money with minimal risk.
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.
Convenience
Players across the globe can log in to a gaming account from their mobile device and access the best in 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 some top tips…

Use a trusted site
Don't hand over any money 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. All of our recommended casinos will fit that bill.

Choose the best payment options
Always check whether your local currency is available, and make sure you're eligible to make real-money transactions. Now you can even gamble at crypto casinos if you prefer more anonymity and speedy transfers. Some banking options for online gambling are free to use, and the best casinos provide quick deposits and withdrawals. However, there may also be some form of ID verification process before a withdrawal is authorised.
