What is a slot machine
The word ‘slot’ refers to the action of inserting a coin into a machine, and the name ‘slot machine’ is used all over the world to describe all slots games. Other names include fruit machines (named for the typical symbols on the reels), fruities, pokies and one-armed-bandits.
The history of slot machines goes back to 1891. The first known ‘gambling machine’ was invented by Sittman and Pitt in Brooklyn, New York. Effectively, it was a poker machine, where players would insert a nickel and try to get a winning poker hand. It proved to be incredibly popular, but the odds were hugely in favour of the machine, with some cards being removed in order to reduce a player’s chances of winning. The machine also wasn’t capable of paying out cash, so players would get rewarded in free drinks and cigars.
It was this machine that gave way to the Liberty Bell, which is widely regarded as being the first real slot machine. This machine used 3 reels with symbols, rather than playing cards, and the idea was to match the symbols to win a prize. This is still the premise that is used today, and although slots have come a long way, they still follow the same pattern as the Liberty Bell.
Modern-day internet slots don’t require you to insert your cash directly into a machine. And with software developers making new and exciting games every month, the possibilities are now endless. But we can still look back and thank the Liberty Bell and Sittman and Pitt’s gambling machine for the slot games we all know and love today.
RTP (Return to player) for slots explained
Return to player (RTP) refers to the amount of money a casino operator expects you to get back over a period of time when playing one game. This number is worked out as a percentage. So, for example, if a games says it has an RTP of 50%, this means you’re expected to get back 50p of each pound that you spend on the game. Luckily, slots RTP is much higher than 50%! In fact, some slots have an RTP of over 99%, so you have a much better chance of winning your money back.

Important when choosing an online slots casino
Playing online casino slots is a fun way to have a little flutter. There are loads of amazing new slots with incredible graphics and ingenious gameplay on the market right now. So it’s fair to say that there’s something out there for everybody. However, with such a huge selection of games comes the question of where to play.
You should take a number of things into consideration when playing slots online.
- Game selection: a big game choice can make it hard to decide where to play, but by the same token, it’s still important that there are plenty of games on offer. Not only does a wide variety mean more entertainment for the customers, but also that many different software companies are happy to be in partnership with the casino. This is a good indicator that they have a solid reputation in the industry
- Licensing: if you’re playing slot sites UK, then you should check that the site has a valid UKGC licence. It’s a legal requirement for any casino operator offering their games to players in the UK. Keeping yourself safe when playing online is super important
- Payment options: top slot sites will have lots of ways for you to make deposits and withdrawals. It can be really frustrating when you find a site you like after doing all your research only to discover that they don’t accept your preferred payment method
- Customer service: always look out for simple and clear lines of communication between you and the casino. There may be a technical hiccup along the way and you’ll need to contact them quickly to resolve any problems.
Featured slots game providers
Online gaming has seen many smaller casinos come and go over the years and the same can be said for software providers. It’s a tough industry to break into for anybody. Competition is fierce and those without a watertight business model fall by the wayside.
Today, the industry finds itself in an interesting moment where there’s a huge opportunity for growth. There are several big names that have made it all the way since casinos first went online 25 years ago and also some smaller independent studios who are proving that there’s still room for newcomers.
For more than two decades, NetEnt has been providing some of the most popular slots to casino sites across the globe. They focus on engaging games with incredible graphics and gameplay to create an immersive experience, which is much more than simply gambling. Starburst has been one of their most popular titles along with Gonzo’s Quest. The arrival of their new ‘Rome – The Golden Age’ slot is eagerly anticipated this year.
Playtech is one of the biggest software providers in the online gambling industry. They claim to be the largest casino software provider listed on the London Stock Exchange, which does go to show that they are certainly a force to be reckoned with in this arena. Their games have been entertaining the masses since the turn of the century, and they have grown in strength and statute during that time. Titles such as Age of The Gods and Batman Begins were both from this studio.
Microgaming has been around since the idea of online gambling was first thought up. They created their famous Gaming Club, which many believe to be the first online casino, in the mid-90s. Over the last 20 years, they have designed some hugely successful slots. They have constantly pushed the boundaries over the years, and are at the cutting edge of many new introductions to the sector. Back in 2006, they brought out their incredibly popular Mega Moolah progressive slot that has gradually turned into an entire range of machines all linked together to bring punters some of the biggest jackpots imaginable.
The Novomatic brand started out life in the early 80s as a physical slot machine manufacturer. Their products can be found all over the world and some say that they are now the largest in the business. They came a little later to the online party —so to speak— when they bought Greentube Internet Entertainment Solutions about 10 years ago. They are now highly regarded in the industry and players will often seek out their games.
Play’n go’s software has worked itself into a nice little niche in the gaming world. Their Omny-Channel Magic product means that a player’s game progress can be transferred through both digital and land-based casino devices instantly. A profile system stores your data and lets you enjoy the same gaming experience wherever you are. They have also created some amazing slots including The Faces of Freya and Thunderscreech.
SG has been involved in all areas of the casino business over the years. From lotteries to slot machines, there’s not much that they haven’t done. Several smaller brands have been taken under their wing giving them the ability to have a huge influence in every aspect of the gambling world.
This small Swedish studio has built itself a good reputation for breaking away from the traditional. Where many slots follow the same pattern, Thunderkick games add their own take on how things should look. Have a few spins on their fabulous game Esqueleto Explosivo and you’ll see how they’ve done it. Not only have they created an amazing graphical display with skulls flying out of the screen rather than simply spinning reels, but they have also introduced a ton of innovative ways to multiply bonuses and enjoy different types of features.
