If you are a UK player, interested in testing your luck at progressive jackpot slots, the following article may be of interest to you since it contains detailed information on how to choose a reliable UK-friendly casino and which the most lucrative progressive jackpot slots are.

Choosing UK Casinos to Play Jackpot Slots at

There are literally hundreds of casinos available online but the question many players from the UK are probably asking themselves is how to choose an online gambling provider they can trust. There are several key criteria to look for prior to opening an account at any online casino.

First and foremost, UK players are recommended to make sure their preferred online casino welcomes customers from their country. The good news is all of the online casinos we have reviewed welcome players from the United Kingdom.

Before you complete your registration, it is advisable to first check which regulatory bodies have issued the licenses of your casino of choice. This information is typically displayed at the bottom of the casino’s homepage, so if you see the UK Gambling Commission listed there, this would mean the gambling operator is legitimate. Other stringent and well-respected regulatory authorities to look for include the Gibraltar Gambling Commission, the Maltese Gaming Authority and the Alderney Gambling Control Commission, among others.

It is always a good idea to check which methods of payment the online casino accepts and whether or not they are suitable for UK players. Some of the most widespread payment solutions, recommended for UK players, include Visa, Mastercard, PaySafeCard, Neteller, Skrill, and PayPal. Checking whether or not your preferred casino processes payments in GBP is a must as using your own currency will help you avoid currency conversion fees. When it comes to withdrawals, it is always a good idea to opt for an online gambling operator that is well-known for its quick and hassle-free cash-outs.

It is always worth checking which software developers the gambling operator has partnered with. Reputable online casinos typically team up with some of the leading names in the industry to ensure their players enjoy a seamless, high-quality gaming experience without any issues or glitches. Some of the most respected software suppliers to look for include giants like Microgaming, Playtech, NetEnt, BetSoft and IGT.

Sometimes players may face an issue with managing their account or may simply require more information on given matters. That is why, it would be best to register an account at an online casino that respects its customers, caters to their needs, and offers them adequate and time-efficient customer support via a dedicated live chat facility. All respected operators in the industry typically have friendly support agents that are on stand-by around the clock to answer players’ questions or help them resolve any ensuing issues.

The last two criteria that define established UK casinos are mobile compatibility and the bonuses on offer. Typically, renowned casino operators reward both new and existing players with various promotional offers and free spins. And the best part of all is that you get to keep the winnings you have accrued with the bonus funds.

Finally, if you insist on being able to play on the go, make sure you check you are opening an account at an online casino that is mobile-responsive. This way, you will be able to load the games directly in your portable device’s browser. Some established casino operators offer dedicated iOS and Android applications that are available for a free download, so installing these apps is yet another convenient option.
