Different Types of UK Slot Games

There are thousands of online UK slots to choose from. What makes them great is that there are so many different themes and styles to choose from. Slots come in several different categories – here are some of the main ones.

Classic Slots

Some slots are designed to resemble the earliest slot machines that came out several decades ago. Known as ‘classic slots’, they were played on a grid 3x3 in size or smaller, and typically had no special features at all. Many people still enjoy playing these slots because of the simpler gameplay experience they offer.

Quite a few providers have released online classic slots. These are much more basic than other slots in terms of their gameplay, but they’re designed with high-quality graphics and sound effects just like other modern slots. Some providers even release classic slots with one or two special features added to make them more appealing to today’s online gamblers.

Video Slots

Video slots are any sort of online slots that use computer-generated video animations. All online slots fall under this category. In fact, any slot that uses a screen can be classed as a video slot. If you head to a land-based casino and play a slot machine that uses a screen, that’s technically a video slot too.

What’s great about video slots is that they’re constantly becoming more advanced in terms of their design and gameplay. They come in pretty much every theme imaginable and can have all sorts of exciting and innovative features.

3D Slots

As the name suggests, these are slots that are created with 3D graphics. They’re a lot more immersive and visually impressive than slots with regular 2D graphics and offer a much more engaging player experience. These slots have a very high standard of design, as well as lots of attention to detail.

With 3D slots, it certainly isn’t a case of all style and no substance. While these slots are very eye-catching thanks to their graphics, they also come with enough special features to make them well worth playing.

Jackpot Slots

Jackpot slots are games that offer jackpot prizes in addition to the regular prizes available in the game. The jackpot is usually won by triggering the jackpot feature during the game.

There are two types of jackpot slots to choose from: fixed jackpots and progressive jackpots. Fixed jackpots have a fixed prize pot that is always the same and does not change.

As the name suggests, with progressive jackpots the value can increase. Progressive jackpot games are often linked across different casinos, and the more people that play the game the higher the jackpot climbs, until it randomly drops!

The majority of slot machine games work in the same way. There's a grid with symbols on it and every time you play, the reels (or columns) spin and there's a new assortment of symbols on the grid. To win, usually three or more matching symbols need to land on a payline, which is a set line across the grid that covers one position per reel. Land enough matching symbols on a payline and you'll be paid, so long as the symbols are on adjacent reels, starting with the leftmost one.

Most of the symbols in a slot game are standard symbols. This means that they award a win if you land enough of them on a payline. However, slots usually have a few bonus symbols too. For example, there's the Scatter (which usually triggers the free spins round for three or more symbols on the reels) and the Wild, which can fill in for any standard symbol to hopefully help you achieve winning combinations.

FAQs About Slot Machine Games

Online Casino Slots in the UK vs Land-Based Slot Machines

There are two main types of slot: online ones and land-based ones. Let's compare the two. We'll have a look at online slot games first. These are digital, screen-based games that you can play at online casinos on all sorts of devices, including computers, laptops, smartphones and tablets. So long as your device is connected to the internet, you can visit an online casino and play some slots.

If you go to a land-based UK casino, you'll find some large slot machine games. These are gaming cabinets that you sit (or stand) on and play slots at. Most casino slot machines are screen-based video slots, though you may come across some that don't have a screen at all. Instead, these slots have a large drum that has the reels on it; there's a lever you have to pull to spin the reels.

So, which one is better? That's up to you to decide. Some prefer playing in land-based casinos because they enjoy the experience of going out and being entertained. Others prefer online slots because of the fact that you can play them from the comfort of your own home or on your mobile. If you'd like to give online casino slots a go, we've got lots of them for you to try out.

History of the Slot Machine

The history of slot machine games goes all the way back to the late 19th century. Back in 1891, a New York-based company called Sittman and Pitt created a five-card poker gaming machine. It had five reels and a single row, with playing cards used instead of symbols. It worked in a simple way: after paying, you would pull the lever to spin the reels and if you lined up a poker hand, you would win. These machines became popular in bars and were the foundation for the slot machine.

Shortly after this machine came out, Charles Augustus Fey created an updated version that had three reels and replaced the playing cards with symbols. His design was copied many times and slot machines became hugely popular throughout the beginning of the 20th century.

At first, the slot machine was known as the 'Liberty Bell' because one of the symbols was designed to resemble the Liberty Bell. However, most slot machines ended up using fruits as symbols and came to be known as 'fruit machines'.

Fast forward to 1976 and the very first video slot was launched. This paved the way for slots to become more advanced, not just in their graphics, but also in their features. Video slot machines became hugely popular at land-based casinos and still are today. Then in the late 90s the first online casino slots were launched, with mobile friendly slots coming out in 2004.
