What is RTP for Slots?
The best online slots games are those which, many would argue, pay well. This is measured by something called the RTP, or Return to Player ratio.
This measures how often or how much a game will pay out over its whole lifetime. It may not be an accurate measure of how much you stand to win overall throughout your plays, but it will give you an indication of how generous a game can be.
RTP aside, there are plenty of factors we bear in mind when it comes to rounding up the best slot sites UK players love to head to. Here is just a brief breakdown of the factors we feel you should always keep in focus.
- Look at current bonus codes and deals. Do they offer you plenty of money to spend on a variety of games, or are they restricted to certain games? What are the wagering requirements like? Will you have to pay back more money than is worth it in the long run?
- Mobile compatibility. Does a site work well across multiple, portable devices? Are there free apps and programs available for you to download? Will all the slots games work on smartphones and tablets? Visit our mobile slots page for more information on these features.
- Developers and technology. Which software developers are on board? Is there a live play option? What types of games are available to play, and do they compete well with slots catalogues elsewhere?
- What options are there when it comes to paying in and cashing out? Can you withdraw using the same method you pay in with? Does the site accept e-wallets, or just cards and bank transfers?
- Is the site fully secure? All good slot sites should have updated security certificates and should protect payments at all times.
- Does the site offer plenty of questions before you start? Is the FAQs section relevant, and are you confident that you want to go ahead and play?
- Is there plenty of customer support available? What are players and industry experts saying about the site and its games? Is there help available when you need it?
- Can you win progressive jackpots, and if so, what is the process for claiming? Are the terms and conditions for claiming and withdrawing generally reasonable?
- Are there regular promotions and deals which you can take part in once you’re a loyal player?
- Finally, do always check the licensing of a website before you get started. Most sites available to play in the UK will be fully regulated and licensed, however, it is still worth you doing the checks. Don’t worry – we only ever list and work with sites which are adequately licensed and fully regulated.
Check out the image below for a summary of the key factors we look at to assess the best online slots brands:
This may not be an exhaustive list of everything you wish to look for in a top slot site. However, these points form the basis for what we look for from great sites we list and review. We think there’s more to a great slot site than just the games and deals. Therefore, do make sure to look into all of the above before you get started.
Choosing Slot Bonuses
What makes for the best slots bonuses? These deals and offers can and will change, which means it is always worth keeping an eye on our reviews and guides to learn more. Big deals and bonus spins on selected games pop up all the time! Rest assured, we work to make sure the sites we partner with are always ready to splash the cash for new joiners and regular players alike.
The best slots bonuses out there in our collective opinion, however, are those which let you really dig into a wealth of different games. While free spins deals and bonus codes will let you sample new games for free, we think the best bonuses out there match your cash when you first sign up.
Claim Your Offers
If you’re serious about signing up for online slots sites, you will likely be putting real money in anyway – so why not double or triple it? A 100% cash matching deal will double the money you put in, and so forth. However, you should also always keep a close eye on wagering terms and conditions.
While some of the best slot sites UK have done away with wagering completely, it is much more likely you will come across a site which will expect you to invest real money before you take any away. High wagering, particularly 80x and above, may be seen as particularly restrictive. Therefore, it always pays to read up on that all-important fine print!
Top-Rated Slots Features
If you’re looking for the top-rated slot games online, we’re ready with lists you can depend on. Some of the most popular slots titles are those which have high RTPs, in the sense that they will be more likely to pay out more often. However, as mentioned, this isn’t always going to be guaranteed.
Some of the top slot games online are those which are simply a lot of fun to play. Big titles and brands such as Rainbow Riches have expanded their remit over the years, which means there are now three or four different takes on the game which you’ll find at sites across the web.
Some of the best-rated slot games include Book of Dead, Starburst, Legacy of Ra, Siberian Storm, and those connected with Jackpot King and Party Pots. These are progressive win titles, which give you the chance to play for thousands, even millions of pounds. You have to be in it to win it, as they say. Why not take a look through the best slot sites UK gamers go for and see what takes your fancy?
Are the Best Slot Sites Safe?
We only promote slot brands which are completely secure and safe to use. All the websites you find here will be fully licensed by an independent body. This means they have to follow guidelines relating to fair play and protecting your personal details.
Our aim is to find the sites which offer exciting games and promotions for players. We always check the security of these sites when it comes to payments and personal information. However, we would always recommend using a secure payment method like PayPal or Paysafecard when playing online.
We have picked out the best and most secure mobile slots sites in our full review and analysis.
