How We Rank UK Online Casinos – Key Criteria and Qualities
The team at OnlineGaming4u have been living and breathing iGaming since 2006 and we know the industry inside and out. Over the years we have gained valuable knowledge and experience of online gambling and have worked closely with casino websites in and around the UK. This has allowed us to put together our ultimate checklist of criteria so that we can vet UK online casinos thoroughly and rank operators from best to least attractive.
We know exactly what to look for, so we recognise the differences between a top online casino and a mediocre website. With a keen eye for new online casinos, we review brands hot off the press, so that we can provide exclusive bonuses directly to you, including free spins on slots, first deposit offers, deposit-match bonuses and loyalty rewards among others.
As part of our extensive service to put players’ interests first, we are happy to share some of the information we collect and use when comparing different casino sites in the UK. You can see exactly what makes a best-rated operator from the ground up.
Casino Bonuses
The type and size of casino bonuses at UK online casinos is one of the first things British players look for. For this reason, we compare a variety of both new and existing player promotions that range from deposit-match offers upon first deposit and sign-up bonuses, through to free spins and no deposit deals. Our casino site is packed full of free bonuses that are rated and reviewed based on value for money, size and wagering requirements.
Game Selection
An online casino without a substantial game selection is nothing. At the very core of the best online casinos is an extensive offering of quality casino games that is updated regularly and categorised by type, theme, jackpot and mechanic. Top games include slots, roulette, blackjack, live dealer games and video poker among others.
Software Developers
Online casino sites in the UK partner with multiple software developers that supply games to the operator for customers to play. We look at the quantity of games, as well as the quality of the software developers partnered with each website. Some of the best casinos on the global market offer games from a mixture of long-established and new developers in the iGaming industry.
Payment Methods
Multiple payment methods is a must for any top casino that wants to accommodate as many players as possible and be flexible for its customers from day one. Players should be able to deposit and withdraw money in a variety of ways and in the quickest time possible, including Bank Transfer, Visa, Mastercard, PayPal, Skrill, Neteller and Apple Pay.
Player Experience
OnlineGaming4u is big on player experience and stresses the importance of an easy to use casino website and customer satisfaction. Not only do we like our referrals to be able to find exactly what they are looking for quickly and efficiently, but solid, long-term relationships are built through experiences that are enjoyable, rewarding and memorable. High satisfaction points include games, registration, bonuses, payouts and jackpots.
Mobile Compatibility
Any online casino website that is not mobile-friendly is never listed within our database and is outranked due to poor service. Modern online gambling now takes place across a variety of devices, including laptops, Android tablets and IOS mobiles. Therefore, players should be able to enjoy casino games for money on any device they choose, and even switch between multiple devices using one member account from any location.
Safety and Security
Security on the front-end and back-end of an online casino is crucial to providing a trusted service and a safe environment that gives peace of mind to its players. Keeping customer data secure and processing payments securely through the use of encrypted connections, privacy tools, identity verification methods and industry standards compliance is of paramount importance.
Customer Support
Online casino sites that want to be taken seriously must, in our eyes, have a minimum of 12-15 hours of daily support available to players that is accessible via multiple channels, including social media, live chat, email and telephone. As casino players ourselves, we understand the frustrations and drawbacks of a gambling operator that is lacking good customer support.
Licensing and Regulation
The legality of all online casinos comes down to the licensing and regulatory information to ensure that it has been granted permission to legally operator in its active jurisdiction. In order to operate within the UK gambling market, casino sites must be licensed and regulated by the Gambling Commission as part of player protections, compliance and industry best practice. Some gambling operators hold multiple licenses at the same time, including Malta Gaming Authority and Gibraltar Gambling Commissioner.
