However, you would be given a certain credit to play for the duration of the tournament. Ready to join an online slot tournament? In the table below we have listed the best online slots sites offering free slot tournaments and the prizes that you would be competing for.

Online Slots Guide
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 at the best online slots sites. 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, extra spins 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 slot games you can find at the best slot sites UK have five reels – or sometimes even more!
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 jackpot slots can offer some mind-blowing prizes. Depending on the casino policies, the money could be gathered from just this one game or from multiple slots, and even online slots sites, 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. This is a very unique type of game, because of these symbols and you can’t find a common system neither on the best scratchcard sites nor at casinos with blackjack and other table games. When identical symbols appear in a certain pattern, called a payline, you win coins 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 slot sites, 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 themes of the online slots 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 and get the free spins. Normally, the more scatter symbols you land, the more extra spins you win.
- 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 available in our list of online casinos for UK players. 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 and welcome bonuses, 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. Take the slots of Thunderkick as an 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 extra spins 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 some of the best online slots sites even provide 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 welcome bonus, slots bonus or another promotion.
Slots are a great game to turn that welcome 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 slot games can be quite noisy. The variety of those options depends on the slot site and the game itself. Newer games generally look way better and have more settings to play with. Of course, you can enjoy the best gambling games even if you are not a fan of 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. Some of the developers also provide table games at UK live casinos in addition to their slot games. 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.
- NetEnt 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.
- Microgaming 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. Their classic games include titles like Avalon II, Thunderstruck II, Terminator II, Immortal Romance, and the legendary Mega Moolah, which we already mentioned. 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.
- Playtech This company has been developing gambling software for more than 15 years now and is arguably the most popular one of its kind. Unlike other companies who just develop games, Playtech raises the level and supplies casino sites with entire multifunctional platforms. That is why they are the preferred developer for many of the top casino operators in the UK, such as Ladbrokes, Casino.com, William Hill, Gala and Titanbet. 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 commonly met at the best online slots sites are Monty Python’s Spamalot, King Kong, Gladiator, Pink Panther, Rocky and the Mummy, to mention but a few.
- Random Logic You will not find games by Random Logic on many websites. That’s not because they are not good – it’s just that RandomLogic is a part of the 888 Group, which means that it creates games exclusively for 888 Casino. They are doing an excellent job because the games look and play great – both in the desktop and mobile versions of the casino. What makes Random Logic stand out is the uniqueness of their slot games, bonus and extra spins features. You will understand what we are talking about as soon as you play one of the games – Millionaire Genie, Snack Time, Ultimate Universe, and more. They are also responsible for some of the best progressive jackpot slots found at 888 – like Pirates Millions an Ultimate Grill Thrills. Even though they are not among the most famous names in the business, their portfolio is full of quality games that are definitely worth playing. Visit 888 to give them a try!
