History of Slots

A decade before the turn of the 20th century, a young Bavarian, living in San Francisco, Charles Fey, invented the first slot machine (circa 1889-1895) a one-armed bandit, which he named the Liberty Bell. With automatic payouts and reels filled with playing card symbols and fruits, the biggest prize was a tidy 10 nickels. The Liberty Bell was the first Slot Machine to be mass-produced and rolled out across the States, seeing great success. If you’re a history buff, Fey’s first Liberty Bell is still on display in the Liberty Bell Restaurant, Reno- if you live in the area or ever find yourself near, go take a look at this early Slot Machine.

Since this landmark moment, Slots have gone through distinct periods of evolution and change; in 1964 as electricity because accessible electromechanical Slots came into being; by 1952 the first Video Slot was invented for the Hilton Hotel, Las Vegas; the late 1990s brought the internet and online payment gateways creating the ability for online gaming and starting a period of non-stop innovation; and by the mid 00s, Mobile Slots had been created for players on the go.

Online Slot Software made Slots mainstream, it opened the gaming market to players worldwide and removed the traditional barriers to innovation for Slots such as physical machine size and reels which limited the paylines, structure and form of the game and bonus rounds. Since, Video Slots have become mainstream as have Progressive Jackpots and many other new ideas can now be piloted as online software provides unlimited opportunities to create new types of game.

Breaking it Down: What is A Slot Machine?

A Slot Machine is a game made up of reels, symbols and paylines. When a coin is inserted to a Slot Machine, it activates the reels, which spin. When they come to an end if the symbols shown on-screen match according to any payouts shown in the game’s paytable, you’ll win the corresponding amount.

Not so complication right? Well, things have changed a bit since the early style machines. Unlike physical Slots and older machines, which were created with a fixed number of payouts, symbols, and betlines, the best Online Slots are games that are created using game software, which does not have the same physical limits of creation or gameplay.

Online Slots are far more complicated, programmed with winning patterns and possible outcomes, RNG (Random Number Generator) is used to ensure that every spin is individual and random, selecting one of the mapped outcomes.

As there are no physical reels, the best Online Slots UK can have any number of winning combinations, paylines and additional bonus rounds, which are often played out on new reels or a new game screen with everything mapped into the software and chosen at random during the gameplay- this is why playing Online Slots in the UK is about luck.

What do RTP and Volatility Mean in Slots Online?

Modern Slots come with modern terminology, that players need to have a handle on as it can help you to understand an Online Slot and to pick which you want to play!

RTP: Return to Player is the total amount of players stakes a Slot Machine returns. It is always expressed as a per cent of 100, which the remaining amount reflecting the casino’s profit. Note that RTP is the outcome of ALL players and not an individual experience.

Volatility: As the RNG provides random results from every spin, Volatility is used to describe how the Slot generally pays out. For example, High Volatility means that wins are often few and far between, but of larger amounts, Medium Volatility provides a good balance between the number of wins and amount and a Low Volatility Slot provides small wins often.

Ideally, players should combine the RTP and Volatility stats to decide which game they will enjoy playing most and potentially profit from. Slot reviews are a great way to find out about RTP and Volatility, but also most games publish the RTP in the game rules.

The Different Slots You’ll Find Online in the UK Today

When you first start playing Online Slots UK, you’ll probably be baffled by the amazing array of titles on offer. You’ll generally find that they fall into one of three different categories: Video Slots, Classic Slots, and Progressive Jackpot Slots. You can find out about each of these different slot types when you read below…

  • • Video Slots: The most common and popular type of Online Slot UK is the mighty Video Slot, and this generally has enhanced graphics, multiple bonus features, and an interesting theme. The jackpots at Video Slots are at a set level (unlike progressive jackpot slots, as you’ll see shortly) and it is sometimes possible to alter the number of paylines. Playing the highest number of paylines possible is generally the best strategy though, and some have thousands of different ways to win. Video Slots are where the most innovation is seen as they are the most popular with players Modern Video Slot trends include Megaways from Big Time Gaming, that provide thousands of ways to win, levelling up through bonus rounds like IGT’s Ghostbusters Plus or moving through mapped areas, such as Castle Builder 2 from Rabcat!
  • • Classic Slots: these are simpler machines – games that hark back to the golden days of the fruit machine when all you’d find were three reels, a couple of paylines, and certainly no spectacular bonus rounds. Classic Slots aren’t for everyone, as some people find that they are boring to play, but others love the simplicity they bring and advocate fewer paylines with better payouts. Despite their basic appearances, Classic Slots do differ from one to the next, and they’re an integral part of all UK Slot Sites.
  • • Progressive Jackpot Slots: these can fall into the category of Video Slot or Classic Slot, however, they are different from most Slot Machines in one important way: the prizes.

While standard Slots have a jackpot that remains the same, Progressive Slots have jackpots that keep rising as more people play the game, with each bet depositing a percentage into the pooled pot.

Progressive Jackpots are generally very hard to win, but this means they can sometimes accumulate to well over £10,000,000, especially the most popular titles like Microgaming’s Mega Moolah Slot, or NetEnt’s Divine Fortune- both of which have smashed through records for paying out over £15,000,000! Even if you don’t win the progressive jackpot, you can still manage to win some impressive prizes when you play them at UK Slot Sites.

Who Are Microgaming, NetEnt and Playtech?

There’s something that many people don’t realise: the sites don’t generally make the games themselves. Instead, these games are made by software providers, and the three biggest names are Microgaming, NetEnt and Playtech, but there are many, many, more like IGT and Scientific Gaming, but they are less popular.

You will find at least one of these software providers at every site we recommend to you, regardless of whether the site is well-established, or whether it’s one of the many New Slots Sites started almost every week, ensuring that you’ll always find great games, regardless of which recommended casino you decide to join.

Don’t think that casinos only have games from these three suppliers though, as there are also loads of others producing great games too. Some of these companies are larger and trying to push the big three, and these include companies like Betsoft and Quickspin, while some are smaller, such as Rabcat and Elk Studios. When all software providers come together though, they should create a site that is diverse and incredibly enjoyable to play at and it is possible to find Slots Site that stock games from more than 30+ software developers, although it is up to the casino, which games from each developer they stock.

UK Slot Sites & Online Casinos

Now you’ve got a firm grasp on the world of Slots, let’s take a look at where you can play them- Online Slot Sites and Casinos.

How to Select the Best Slot Site

Picking the best UK Slot Sites is a tough process, as there are loads of different things you need to consider. We’d recommend that you start by looking through our list of the top 10 Slot Sites for UK players though – a list that has been compiled by expert online gamblers and casino critics, who have thought long and hard about which sites to include. Once you have selected two or three sites from the list, read the full review and narrow down your choice by considering the following:

  • • Which site offers the best bonus for you?
  • • Which site has the kind of games you most enjoy playing?
  • • Which site’s general look and feel appeals to you?
  • • Which site offers the payment methods you want to use?
  • • Which site has games from your favourite software provider?

Of course, you don’t necessarily need to whittle down the number of Slot Sites though, as it’s perfectly acceptable to join more than one! By doing so, you’ll be giving yourself access to the largest number of games possible, plus you’ll also be able to get loads of fantastic bonuses, including a number of first deposit bonus offers and many free spins – free spins that could help you win a massive pile of cash!

Features of Top UK Slot Sites and Casinos

All of the Slot Sites on our list of the top places to play are unique, which helps to ensure that everyone finds something they love. They do share some important features as well though, as good slots sites absolutely must exhibit some important qualities. These are:

  • • Safety and Security: All Slot Sites that UK players can use must be properly regulated, licenced by the Uk Gambling Commission and also have systems in place to protect your data, such as SSL encryption. We will never recommend a site that doesn’t make your safety and security their top priority.
  • • Solid Games Collection: All good Slot Sites should absolutely offer a massive range of games to gamblers, including a large selection of Slots. Most Online Casinos will offer hundreds of slot games, as well as loads of table games and live dealer games.
  • • Great Bonuses and Promotions: Every site on our list has great bonuses, however the most important of these are the welcome bonuses. We believe a site should always give something back to their players, and this comes in the form of bonuses.
  • • High Levels of Customer Support: You probably won’t think customer support is too important until you finally need them for something! Our recommended sites have many contact options, plus the customer service is both fast and helpful.
  • • Great Reputation: Finally, all the casinos we recommend to you must have a fantastic reputation within the UK gambling community. If they don’t and have founded complaints or sanctions listed against them, they won’t make the cut.

The Best Online UK Casino Bonuses for Slot Players

While the game selections, security features and customer service are all important, we recognise that bonuses also play a massive role when someone is looking through new casino sites. So, we make bonuses a top priority when reviewing sites.

In general, you’ll find two main types of bonuses at a casino: deposit bonuses and no deposit bonuses. The former is generally expressed as a percentage and are given to those making a deposit, while the latter, as the name suggests, is completely free, with no requirement for the player to ever add their own money to the site, simply sign-up and start playing with free credits.

There are other bonus types too though, and one of the most important for Slot fans is free spins. These are often given as part of a welcome bonus, and they are also sometimes given when a new slot is released, as the site is anxious for people to try it out and enjoy it. The loyalty scheme is also a vital part of many online casino sites, as well as online bingo sites and online sportsbooks, and this gives points to those playing at the site, encouraging people to stay loyal to the site and not move elsewhere.

When we look through the bonuses offered by a site, we’re not only going to look at the amount of money though. This is because bonuses are more complex than that, and we want you to get the entire picture. So, we’ll also look at things like the rollover requirement (the number of times you must wager the bonus before withdrawing), as well as the amount of time the bonus is active for and any other specific rules you need to be aware of. By doing this, we know you’ll only get the best bonuses around and run a much smaller risk of losing a bonus by breaking the terms and conditions.

How to Stay Safe at Online Slots UK Sites

Some people are concerned about how safe Slot Sites are, and we understand this. After all, to the uninitiated eye, it can look like Slots are easily manipulated, and that they, therefore, aren’t entirely trustworthy. This couldn’t be further from the truth though, as all reputable casinos are fully regulated by the UK Gambling Commission – a legal requirement for all casinos accepting UK gamblers – plus good sites also have their games scrutinised by an independent company, the largest of which is eCOGRA, but also keep an eye out for iTech Labs.

Of course, there are some things you can do to keep yourself safe though such as never inputting your banking details when on an internet connection you do not know or trust, like a coffee shop wifi connection. Instead, only ever deposit and withdraw when using your connection, or that owned by a friend or family member. Another thing to remember is this – don’t leave yourself logged in when using a shared computer, and don’t save your details on a mobile, laptop or tablet just in case you accidentally lose it.
