How BonusCodeBets chose the best online casino sites
Deciding which casino sites are the best ones to feature isn’t a simple task. Many unregulated sites would love to be featured in our tables on BonusCodeBets, but the safety of our visitors is always at the forefront of our minds.
The first step we take is to review the online casino sites for customers. There are a few factors we consider when choosing the best UK online casino sites to play at, and we have a detailed structure which helps enable us to find the best online casino sites around. Here are the factors that we take into account to work out how good the user experience is on online casino sites for customers.
- Online Casino User Experience
- Ranger of Casino Games Available
- Casino Sites Bonuses and Promotions
- Casino Sites Banking Payment Options
- Casino Customer Services
- Casino Sites Security
- Mobile site/app convenience and practicality
- Offers and promotions for new and existing customers
Online Casino Sites User Experience
- User experience can make or break a casino site. Ensuring the graphics look modern and the pages are intuitive to navigate is crucial when deciding the best UK casino sites to play at. With people constantly on the internet now, they expect the site to also run quickly, with no lagging issues or struggles when trying to load a page.
Range of Casino Games available
- While we all have our favourite slot games, having access to the widest choice and newest games can be the difference between sticking with the casino site you are on and looking for new casino sites to try out. Now, the experience on online casino sites is a lot different, with there now being live games which have presenters or dealers.
Casino Sites Bonuses and Promotions
- First impressions are crucial, so getting underway with a generous and easy-to-use new customer casino welcome bonus is key. Most of the sites we recommend offer a large amount of free spins to get you started.
Casino Sites Banking Payment Options
- It can be frustrating to be restricted to a single payment so we endeavour to ensure all our recommended casino sites offer a good selection of payment options. We check to make sure the casino sites offer smooth deposits and withdrawals, whilst we also check that they provide fast and free payment methods for both deposits and withdrawals.
It is also important that Casino sites have the most popular deposit and withdrawal methods, so we typically look out to make sure whether they have:
- Debit Cards
- PayPal, Skrill and Neteller
- Bank Transfers
- Google/Apple Pay
- Trustly
- PaySafeCard
Casino Customer Service
- Gone are the days of sending an email and waiting for days for a reply. Live Chat and Direct Messaging is the future, so look out for our chosen casino sites, which give you access to a helping hand in the shortest time possible.
Casino Sites Security
- There’s no point winning a big jackpot on the slots if you’re unable to access your winnings. Secure banking methods and player protection are vital for any platform that strives to be one of the top UK casino sites. We therefore ensure that all the slots sites included on BonusCodeBets have a regulated license, so your funds are completely secure.
Mobile site/app convenience and practicality
- We also look into how good their mobile site or mobile app is, making sure that it runs smoothly and that it provides a good experience for all users. It is crucial that the user experience on casino sites’ mobile apps is good so that customers can have an enjoyable experience on the move.
Online Casino Sites offers and promotions for new and existing customers
- New and existing customers will always be looking out for new offers and promotions, be it loyalty clubs, free spins, free bonuses or daily free games. We have a look at what each casino site offers to make sure we find the best casino sites.
- After we look into all these factors, our team at BonusCodeBets can look into rating each casino site. This is why we provide you with our top 10 casino sites at this current time. This list can change from time-to-time if we feel like another casino site deserves to be in the top 10, be it a very experienced casino site or a relatively new one which has impressed.
How to sign up for a casino site
Signing up for a casino site is a straightforward process, with dedicated landing pages and Live Chat facilities on hand to guide you through if you happen to hit a stumbling block. Realistically, that shouldn’t be necessary though. To give you an idea of the casino sign up process, here a step-by-step guide to signing up with bet365 casino, who are amongst our top rated casino sites in the UK.
1. Head over to the bet365 Casino site, and if you are registering for the first time, make sure you use the bet365 casino sign up offer link we have provided
2. Click the ‘Join’ button in the top right corner of the site.
3. Fill out the registration form, including your personal details and contact preferences.
4. Choose a secure username and password, and verify your details if asked.
5. Click the green ‘Join bet365’ button, at the bottom of the registration form.
6. Once you join, bet365 will direct you to the bet365 casino homepage. Here, you can make your first deposit and get playing.
Why play at online casino sites?
It has become far more appealing to choose online casino sites over land-based casinos in recent years. Some of the key benefits are below:
1. Most sites will have a free to download app, allowing you to play whenever and wherever you want, rather than having to abide by opening hours.
2. You can find a table that suits your needs. For some this may mean playing one-on-one so there’s no waiting around for others to make their decisions. For others, this will mean joining a live casino table to take in the experience of a live dealer and engage in chat with the dealer and other players.
3. You can play demo slots games to see whether a game is entertaining and what you’re after, as opposed to be forced straight into real money slots at a land-based casino.
4. As for any winnings, they’ll automatically be credited to your account, and can generally be withdrawn to your bank account within hours, so there really are plenty of selling points in favour of the online casino experience nowadays.
