Casinos with Highest Slot Payouts

Slots are without a doubt one of the most entertaining casino games, but we should not forget that players’ main aim is winning. While it is true that slots are mostly game of luck, there is a way to increase your chance of winning. By choosing slot games with a relatively high RTP, you can be confident that a certain percentage of wagered money would be paid back to you. Thus, theoretically speaking, you should always select games with an RTP higher than 96%. Of course, it might be difficult to find the highest RTP slots and the casinos that offer them. To help you choose the most convenient operator for you, we have conducted extensive research to find out which slot sites offer the highest payouts and the most generous bonuses. In the table below you will find our top 5 casinos with highest slot payouts, and the top 3 high RTP slots that they offer:

Bear in mind, however, that all of the payouts stated above are theoretical and there are other factors that could affect the maximum payout. These include the maximum betting limit, bets per line and bets per spin. Moreover, the presence of wilds, free spins, bonus rounds and multipliers can also impact the game’s maximum win. Thus, apart from a high RTP you must always consider the presence of other details that could affect the amount of your rewards.

In order to be able to enjoy your favourite slot games fully, you must always make sure that you have enough funds to play as much as you like.

Shall you wish to withdraw any winnings to your bonus, however, you will be required to fulfil certain wagering requirements, usually for a certain period of time. Wondering what online casinos offer the lowest wagering conditions? For your convenience, we have listed the best slot sites with low wagering bonus requirements in the table below.

Unfortunately, while certain casinos may offer surprisingly generous bonuses, their wagering conditions might be almost impossible to complete. Thus, you must always read the corresponding terms and conditions before making a deposit. Generally speaking, you should avoid bonus wagering requirements of 50x or more as they are the hardest to meet. Meanwhile, medium wagers of 35x to 40x are easier to complete as long as you are given enough time. Technically, however, you should always aim for casinos with low wagering requirements of less than 30x, as they are the easiest to meet.

Best Slot Sites with No Wagering Requirement

Luckily, certain online casinos allow you to enjoy your bonus without having to meet any wagering requirements. In most cases, however, your bonus will consist of free spins and not of cash to play with. Nevertheless, you must bear in mind that the number of free spins that you receive might vary depending on how much you have deposited. You must also always check the bonus validity as some offers expire after a certain amount of time. While some operators may tie their free spins to a certain slot, others would allow you to use your bonus on each online slot you like. Wondering which is the best slot site with no wagering requirement? As you can see below, our top choice offers a welcome bonus of up to 50 free spins for an unlimited period of time. Click on the button below to claim your bonus and enjoy your favourite slot games.

Online Casinos Offering Free Slot Tournaments

Slot tournaments are without a doubt one the most exciting features that an online casino may offer. They work in a simple way. The basic structure of an online slot tournament involves accumulating points rather than cash. The tournament rules may vary depending on the game and the online casino you are playing at but generally speaking, players will be competing and trying to collect the highest number of points or cash before the time runs out. While some online casinos offer free entries, you might occasionally be asked to pay a certain amount to enter the tournament. However, you would be given a certain credit to play with aiming to win as much cash as you can for the duration of the tournament. Ready to join an online slot tournament? In the table below we have listed the best online casinos offering free slot tournaments and the prizes that you would be competing for

Online Casinos Free Slot Tournaments Prize Slot Site Rating Secure Link

NetBet Tournaments 100 Free Spins 4.70/5.00 casino.netbet.co.uk/tournaments

Most tournaments would often offer little prizes along the way as well as a big cash prize for the winner. The slot tournaments may have a set prize pool, or it might be continually growing depending on the number of players that have enrolled. As with all slot games, your ranking in the tournament would depend mostly on your luck. To increase your chance of winning, however, it is advisable to bet the maximum amount possible, spin fast and take the best advantage of the slot’s bonus rounds and free spins.

New Slot Sites

The constantly growing popularity of the slot games and the increasing player interest in them have led to the necessity of more casino sites that satisfy the customers’ need for a wide slot variety and generous bonuses. Thus, it comes as no surprise that in recent years we have witnessed the launch of many slot sites that have managed to become popular and to confirm their firm position on the gambling market in a short time. Wondering why? Most new slot sites count with rich collections of slots from various software developers, including Microgaming and Playtech. Eager to find out which are the top new slot sites in the UK? Take a look at the table below to find out:

The new operators offer many special promotions and lucrative welcome bonuses. All of our recommended operators offer a wide variety of desktop and mobile-friendly slots, many progressive jackpot slots and, of course, generous bonuses. Nevertheless, we remind you to always read the corresponding bonus terms and conditions at your chosen slots casino to avoid misunderstandings. Are you worried about your safety? We have tested and reviewed all of our new recommended slots casinos and all of them are licenced by official authorities such as the United Kingdom Gambling Commission and the Malta Gaming Authority, so you can be sure that your security and fair play are guaranteed.

There are so many slot games online that it’s only natural that you’d be at a loss which one to choose. And since there are a few things to take into consideration when picking a game, a short but informative overview of a slot might save you a lot of time and money. That’s why we have prepared reviews of the games you might be interested in. In these, we provide an objective opinion on the pros and cons of each slot and give you the chance to try them in practice mode. If you need help picking a slot game that satisfies your needs, have a look at some of the most popular titles among British casino players:

We hope you’ve found our selection of game reviews useful. And even though it includes quite an impressive number of games, it might happen just so that you can’t find the title you’re looking for. If that is the case, don’t worry. The current one is not the final version of our list of top online slots. We are constantly adding dedicated pages for games, so make sure you check back with us regularly for more slot reviews.

Game Overview – Gameplay & Variations

We doubt that there is a person alive who doesn’t know how slot machines work. Even if you have never played one, you have certainly seen someone playing them, either in person or in the movies. Still, we could all use a little refresher, so here are the basics of how slots work. We’ll start with the different types of slots. Then, we’ll give you a list of the special symbols and their combinations. Finally, we’ll focus on the software and how to personalise your game.

The Different Types of Slot Machines

The first slot machine was invented at the end of the 19th century. Since then, there have been a lot of imitations. Originally, all slot machines had three reels – that characteristic stuck for quite some time. Nowadays, most slots you will come across at both online and land-based casinos have five reels. The greater the number of reels, the more the possible combinations – hence, more opportunities for wins and bonus rounds. So, keeping things simple, this is the basic categorisation when it comes to slots – 3 vs 5 reels. The classic 3-reel format is still quite popular to this day, especially for fans of retro looks, but 5-reel slots have been leading the way for some time now. Most of the new video slots you can find online have five reels – or sometimes even more!

Classic 3 Reel Slots

5 Reel Video Slots

Even without considering the number of reels, there are literally thousands of different slot variations and themes. There are, of course, other characteristics that could put slots into different categories. For instance, a slot could have a progressive or non-progressive jackpot. Progressive jackpots get bigger and bigger each time a player plays them. Depending on the casino policies, the money could be gathered from just this one game or from multiple slots at the same time. Progressive jackpots often get huge, and you will see them featured on the home page of many online casinos. The Guinness World Record for the largest jackpot paid out by an online slot machine is £13,209,300 – it was won by Jon Heywood, a UK citizen, who was playing Mega Moolah at Betway Casino. The record is yet to be broken, though it has come close a few times.

Combinations & Special Symbols

Slot machines have 3 or 5 reels with symbols all over them. When identical symbols appear in a certain pattern, called a payline, you win a sum of money depending on the number of identical symbols and their value according to the paytable. At land-based casinos, you spin the wheels by pulling a lever or hitting a button. At online casinos, you click the ‘spin’ button. Once you initiate a round, all you can do is hope that three or more of the same symbols will land on a payline. Usually, the symbols need not only to appear on a payline but also to start from the leftmost reel.

As far as symbols go, these can be pretty much anything you can imagine. They fit the theme of the slot beautifully and add to your gaming experience immensely. However, certain special symbols are featured in almost all slot machines in one form or another. You’ll love these for their special powers. Let’s take a look.

  • Wild – In its simplest form, this symbol substitutes all others except for the Scatter symbol. This means that the Wild can be used to complete any combination on any payline, which makes it your best friend. Some variations of the game have different uses for the Wild. For example, some slots have Wild Multiplier symbols – it not only completes your combination but multiplies the winnings from it.
  • Scatter – This special symbol can reward you with a winning payout, free spins or even a bonus game. There are certain conditions that need to be fulfilled for it to work, though. They are different from game to game. For instance, on this one slot machine that I enjoyed playing, you had to be lucky enough to get three Scatter symbols at once anywhere on the screen in order to unlock the bonus level.
  • Multiplier – This symbol serves to increase your winnings several times and they usually add up in time. A good example would be the excellent game Gonzo’s Quest, in which the multiplier can reach up to x15!

These three special symbols are the most common ones but, in fact, there are a lot more. We’re not going to go over all the possibilities here in detail because, when it comes to the variety of slot machines, the sky is the limit. We’ll do something better. Make sure you check out our slot reviews, where we give you all the important info on each game separately. We believe that would be a much more helpful way for you to discover the particulars of special symbols.

Software & Settings

There are many advantages of playing slots online rather than at a brick-and-mortar casino. There is a great variety of games, no doubt, but there are also multiple ways to enhance your experience that are not available offline. Those personalisation options not only customise your game but can actually help you save time and get to those big winnings faster. For example, you can easily adjust your stake by decreasing or increasing the ‘coin value’ and the ‘bet level’ – the wide range of options lets you play with your stake and settle on the one most comfortable for you. Once you’ve done that, you can easily take care of any time-wasting actions. You can do that in two ways. On the one hand, there’s the awesome ‘Quick Spin’ option, which significantly reduces the time it takes for a spin to finish. Sure, it takes away from the suspense of the game, but it’s really helpful if you want to get to those bonuses and big wins quicker. On the other hand, there’s the handy ‘Auto Spin’ option, which takes away the boring clicking on the ‘spin’ button. You can choose a preset number of spins to be performed and sometimes you even have the option to auto spin until reaching a bonus round, which is really great. Both time-saving options come handy when you need to play through a bonus. Slots are a great game to turn that bonus over the required number of times because they contribute 100% to the wagering requirements. Certainly, you can also adjust the technical aspects of the game – graphic quality, sound level, etc. Those options are especially useful as slots machines can be quite noisy. The variety of those options depends on the game itself and how old it is – newer games generally look way better and have more settings to play with.

The Best Slot Machine Software Developers

The online gambling industry keeps on growing and evolving and there are plenty of companies that create cutting-edge software for it. When it comes to online slots, there are quite a few companies out there. For the purpose of this review, however, we will take a detailed look only at the most popular ones. These are the top gaming software developers and they have stood the test of time and proven their quality over and over again. Moreover, they’re undergoing constant changes to become even better in the process. In the table below, you will find listed the biggest software developers along with their most popular slots.

Each of the aforementioned software developers has a rich slot collection and is constantly developing new and challenging games. Furthermore, the software developers that we have recommended are not only well-established in the industry but also safe and certified. Bear in mind, however, that each slot’s betting limits may vary depending on the online casino you are playing at. Eager to find out more about the software developers? We have listed further information below, alternatively, you can read each developer’s review by clicking on its logo in the table above.

Software Houses That Develop Great Online Slots

When it comes to excellence in online gambling software, the name of Net Entertainment is sure to come up. Their portfolio is not the biggest one, but it has some of the best online slots we have ever played – like Gonzo’s Quest, Jack Hammer, Jack and the Beanstalk, Starburst and many more. Players who have been around the block will probably recognise a NetEnt game simply by looking at it, as the superior graphics and interesting themes are a huge tell. The games developed by NetEnt are thoroughly tested and proven to be 100% fair by several independent agencies and gambling authorities – including the UK Gambling Commission, The Malta Gambling Authority, and the Gibraltar Gambling Authority, among others. NetEnt has always been spearheading innovation in both graphics in gameplay, and we are always excited about what they do.

This company was responsible for the creation and launch of the first online casino ever. Microgaming has been around since 1994 and is truly a force to be reckoned with. Given the years that they have in this business, it will probably come as no surprise that they have a catalogue comprised of more than 1000 games – and most of them are slots.

We have to be honest – when it comes to graphics, those games can hardly compare to the quality that NetEnt provides. However, the newer slots Microgaming creates are looking great, and their overall gameplay sets new standards in the field. We are talking about titles like Game of Thrones, Jurassic Park, The Dark Knight, and others.

This company has been developing gambling software for more than 15 years now and is arguably the most popular one of its kind.

As far as their portfolio of online slots goes, Playtech offers a huge selection of over 500 titles, the most popular among which are based on famous movies or TV shows. The easiest way to recognise a Playtech-powered casino is by taking a look at its game library. Some of the most popular titles there are Monty Python’s Spamalot, King Kong, Gladiator, Pink Panther, Rocky and the Mummy, to mention but a few
