At Best non Gamstop Casinos, we take our responsibility as casino critics very seriously. Any online casino recommended on this site has been playtested personally by our experts. As part of our hands-on approach, we create an account, complete identity checks, deposit funds, claim bonuses, play games, and, hopefully, withdraw winnings. All while assessing the site’s design, features, and security.
Below are the key factors we consider when testing and rating casinos.
- Licensing and Security
The first thing we check when reviewing any online casino is its licensing. We only recommend gambling platforms licensed by recognised authorities, such as the UK Gambling Commission, the Malta Gaming Authority, or the Gibraltar Gambling Commissioner. If a casino is unlicensed, we simply let it go.
Equally important to licensing is site security. We only recommend casinos that employ appropriate security features to protect their players’ personal and financial details. Every casino on our list utilises advanced security technologies, including SSL encryption, secure gateways, anti-fraud systems, and two-factor authentication.
- Community Reputation
A casino site’s reputation is something we always consider carefully when weighing up whether or not to recommend a site. We search for real player opinions on online gambling forums and social media platforms.
If the general sentiment around a site appears positive, we continue our playtest with high hopes. But should we see too many frustrated or disenchanted players, we consider this a red flag and proceed with caution.
- Game Variety
Next comes the fun part, getting stuck into the games. We try to recommend casinos that offer a wide variety of games, so that we can be sure they have a broad appeal.
Ideally, our recommended sites will offer multiple variations of online slots, table games, live dealer games, and casual games. We also give preference to sites with games from leading developers like Playtech, Blueprint Gaming, Evolution Gaming, Microgaming, and NetEnt.
- Bonuses and Promotions
We only recommend casino sites offering generous bonuses and excellent ongoing promotions. New players should expect to receive matched deposits and free spins, while regulars can look forward to cashback, reloads, prize wheels and loyalty schemes.
Of course, we don’t rate casinos solely based on the potential value of their bonuses, as the reality of what you will receive is detailed in the terms. When examining a site’s bonuses, we consider the wagering requirements, eligible games, minimum deposits, validity periods and more. Only casinos with reasonable and achievable terms got a place on our list.
- Payment Methods
Next, we analyse the available deposit and withdrawal methods. Before we can consider a casino, we check that it accepts a decent range of payment options. As a minimum, we expect good sites to support transactions via debit card, prepaid voucher, bank transfer, and e-wallet.
Naturally, payment speed matters too. We rank most highly those sites that can facilitate instant deposits and same-day withdrawals. Bonus points for sites that do so without charging transaction fees.
- Mobile Experience
This is 2025, so we expect every casino to offer an exceptional mobile gaming experience. We test each casino site on different devices and screen sizes to see how well it performs. Only casinos that run excellently on both desktop and mobile devices earn our recommendation. Casinos with a dedicated mobile app typically rank highest in our estimations. That said, an app is not a vital requirement for us, as long as the website is well-optimised for mobile use.
- User Experience
If a site’s interface is hard to use, its other positive qualities don’t mean much. At any good casino site, it should be easy to register, fast to deposit funds, and straightforward to find games. Most importantly, though, there should be very little wait to withdraw from the casino. We only recommend online casinos that feature sleek, user-friendly interfaces.
- Customer Support
We want you to be able to find help fast if anything goes wrong. Our expectations for quality customer support are high. So, we only recommend casinos that offer round-the-clock customer support. Sites should also be contactable via multiple channels, including live chat, email, and phone.
