What makes a great online casino?

Every player is looking for something different when they search for the UK's best online casinos. Some want the best welcome packages; others want the widest game selection. The user experience, the payment options, the on-site community and the ease of access to help services can all sway a player.

The very best casino sites will either cater to all these types of player at once, or become the market leader in their particular specialism. For example, an operator might strive to have the biggest welcome bonus, or to allow the greatest number of payment options.

Focusing on one area might limit the number of players who flock to that site, but it should help them capture the market share of players who want one particular feature.

Below, we explore some of the critical USPs and benefits any online casino should consider.

The welcome package

Most new players at any online casino will want to know about the freebies and bonuses available to them. The best online UK casinos will have cash rewards, free spins, deposit match bonuses, or some other benefit available only to new site members. For example, Slot Strike Casino currently offers a £/€50 deposit bonus to new players, plus 50 free spins!

There are usually some restrictions applied to welcome bonuses, such as a wagering requirement that must be played through before the player can withdraw their winnings. Bonus funds and free spins often have a time limit attached, as well. However, these packages are always optional, and they do give the player a chance to explore the site and its games using these perks of new membership.

Online Casino Bonus Tracking

Tracking bonuses collected from the different casinos you've visited has never been easier with our exclusive casino bonus tracking tool completely free to use. Find out more about bonus tracking and starting making the most of your casino bonuses.

The user experience

From the way the site looks to how the player moves through its menus, the website itself is very important to an enjoyable online gambling session. If the games are hard to find, or if their performance is poor, then all the free spins in the world won't make it fun to play there!

That is why the best UK casino sites all tend to have a consistent design theme, and a simple layout with games, account details, money transfers and more all available in just a couple of clicks. They also source their games and their operating software from leading developers, so you are guaranteed reliable game content that doesn't lag or stall. There is nothing worse than a frozen reel spin or dropping out with a live poker hand in play!

The customer service

In the event that something does go wrong, players need to know that they can speak to a real human being who can work to resolve that issue. Great online casinos will have a number of contact options, often including email, telephone and live chat support. These support agents will be helpful and friendly, and they will be able to fix all manner of technical issues, answer questions about the games, and look after the players on the site.

A bad online casino will have very little contact with players, and getting any issues with payments, games or the account can be very difficult. Before signing up with a site, always check the contact page and make sure you would be able to reach the service team. Of course, the casino sites in our top rated list all have incredible customer service!

The community

Many online casinos encourage members to interact with each other. This includes playing in table games together through the live casino function, or in bingo lounges. Plus, there may be a live chat or messaging function so that players can interact this way - often these chat rooms are ‘hosted' by an administrator who can also answer questions by players.

Game leaderboards, social share buttons and big winner lists are another popular way to engage players. Adding a competitive element to the online casino, and allowing players to share their big wins with their friends, can really add to the online gambling experience.

Other communal features include progressive jackpots and linked prizes, which can be part of a video slot's gameplay or the side bet in a table game, for example. Some of the best online casinos are those with a strong sense of community - and of competition!

The payment system

In order to play casino games online for real money, you will need to deposit funds. If you win during your play session, you may want to withdraw that money. Both transactions will require a registered payment method. Which payment methods are accepted, and how long transactions take each way, varies greatly between online casino operators.

Great online casinos tend to offer players a whole selection of payment options. Almost always, a debit or credit card will be accepted: usually the only exceptions are non-money casinos, such as some video gaming sites that allow gambling for cosmetic items, and cryptocurrency casinos. In addition to payment cards, other methods may also be accepted.

Depositing funds to your account is usually very fast, no matter where you play. Often it takes just a matter of minutes to confirm the transaction. However, withdrawing funds can take longer: anywhere between a few hours and a few days. This varies according to the operator, but also to the payment method.

The best online casinos in the UK are known to only accept trusted and reliable payment methods. These sites use encryption software to protect your financial and personal information, so you can play with confidence. All of our top rated casinos are licensed and verified operators who take great care with players' details.

The games

Of course, one the biggest deciding factors in choosing where to play is the casino games on offer. The best mobile casinos and online casinos are those which are stuffed full of fantastic games from all of the top operators. After all, it makes sense that the more choice you have, the greater the chance that you'll find a game you love!

Some casinos will specialise in one or two kinds of games. Bingo sites and online slots sites are two examples of this. Some of the slot-orientated casinos we recommend highly are Fruity Casa, Sloty, and Royal Slots. While these specialist gaming sites often include some other types of game among their catalogue, they focus heavily on their own area, and have an impressive array of those games.

Other casinos will create a balanced set of games that caters to all players. This usually includes slots, electronic casino games, and live casino tables. Bingo, Keno and scratchcards or instant win games are other popular additions to online casino sites.

Best online casinos for slots

One of the most popular games at any online casino are the slots. Even casinos that focus on table games or bingo still tend to have a few slots available! Slot games include classic slots, based on old-style fruit machines and featuring simple gameplay, and the more complex modern video slots. Today's online slots often feature interactive bonus games, high definition graphics and state of the art graphics - not to mention some huge prizes!

Slot games that can be played on mobile devices are extremely popular. That is why the Uk's best online casinos tend to licence games developed using HTML5 software. This advanced programming language allows for a seamless integration of game content onto desktop and mobile devices: perfect for online casinos which welcome both platforms.

Look for casinos that feature content by top game studios. Names such as NetEnt, Microgaming, Barcrest, SG Digital and Play'N Go are a good sign that you're in for a great playing experience. On the other hand, don't be put off by casino sites that have their own independent game content - such as Nektan branded casinos - or those that give lesser known developers a chance. Our top rated casinos list above includes sites with a variety of big name and indie slots, casino games and more, with something to suit every player.

Best live online casinos

Live casino gaming is becoming increasingly popular. Online casinos which offer these games will appeal to anyone seeking a realistic casino experience. Live gambling is just like stepping into a physical casino, except you can do it from the comfort of your own home! The games are streamed from real tables, often with human hosts, and players can bet in real time on the outcome of roulette wheels, blackjack hands and other favourite casino games.

The nation's best online casinos usually include a comprehensive suite of casino games, including electronic casino and live casino variants of blackjack, roulette, poker, baccarat, and Wheel of Fortune. Often, there are high and low limit versions of each game available, so casual gamblers and high rollers alike can enjoy the same great gambling content.
