Guide to the Best Slot Sites

Online slot machines are without doubt the dominant force in the world of online casino games. Everywhere you turn, online casinos are packed to the brim with spinners of all shapes and sizes. From jackpot video slot games, these games are as varied as the players that play them. In fact, if you're a UK gamer looking for a new selection of casino sites in 2019, it should be considered a red flag if a platform doesn't have a ton of slots games. Naturally, finding the best slot sites isn't always easy if you're a newbie.

Yes, there are hundreds of slots online, but not all of them are worth spinning and, moreover, not all of them will suit your playing style. So, with this in mind, we've come up with a quick guide to the best online slots sites. Now, we could simply say, here's a list of our top rated slot sites, go join them. But we realise that everyone is different, so we want to give you the knowledge to find your own casinos and games. In the following few paragraphs, we'll take you through the process of finding the best slot sites and casinos. Using this information, you can then tailor your searches to your own preferences to ensure 2019 is the year you spin in style.

Finding the Best Casino Slot Sites Online

As we've said, all the best online slot sites will offer tens, if not hundreds of slots. Now, if you review the top-rated online slots sites, you'll find a number of games crop up time and time again. As you'd expect, if the same game is available at several slots sites, then it's probably one of the best spinners in the industry. In this sense, these games are probably worth playing and, therefore, the site is worth joining.

However, what happens when you find games at slots casinos that aren't readily available elsewhere? What if an online slot site has its own unique collection of games? In this instance, you need to look to a few features to ensure you're getting the best experience possible. Basically, as a UK player in 2019, you should be looking for the following at the most popular slots sites:

  • Make sure there is a variety of video and jackpot slots.
  • Make sure you can play games for free and for low stakes.
  • Make sure the slots site has a selection of slots bonuses.
  • Make sure the site has a number of established developers, including NetEnt and NextGen.
  • Make sure you can play for progressive jackpots of at least £100,000+.

There are also lots of slot games based on movies that are worth checking out. Playing a slot based on your favourite movie is great fun!

Types of Online Slots

The types of slots you can play online is marked. From size, style and the amount of money you can win, the variations of slots out there is what really makes these games a favourite for players of all persuasions. As a UK spinner in 2019, you'll be able to enjoy the following online slot variants when you join one of our recommend casino sites:

  • Video Slots | The most numerous slot type, video slots include live-action backgrounds, in-game animations and interactive bonus rounds. The best games of 2019 include: Starburst, Big Bad Wolf and Game of Thrones.
  • 3D Slots | Everything from the reels to the betting bar in these games has been given an extra layer of depth. Games like Amazon Queen and Cleopatra take you into a fully immersive world of reels, symbols and prizes.
  • Progressive Jackpot Slots | The leading light in the online slots world, progressive jackpot games have a top prize that's always increasing. A small portion of each player's stake contributes to the jackpot, which means you can win millions from slots such as Mega Moolah and Major Millions.
  • Fruit Machines | These games typically have classic symbols such as fruits, bells and the famous 7. They'll also typically have three reels and some of the best games available in 2019 include Cash Stax and Call of Fruity.

Online Slots Strategy: Reading the Payout Table

Of course, the best part of playing online slots is winning. As part of your online slots strategy, you need to know how to read a payout table. Basically, when you scroll through the potential payouts, you'll notice that everything starts with the paylines. In simple terms, all winning combinations have to start from the left and move across to the right. Although some slots will offer payouts on two matching symbols, it's typically the case that you'll win a prize if you match three, four or five symbols.

Payout tables will either list the prizes in cash amount or as a multiplier. If you see something like 100X, this means the prize will be the size of your single line bet multiplied by 100. Beyond the standard payouts, bonus features also give you the ability to win some cash. These are typically awarded as instant cash amounts or free spins which then credit cash to your balance.

Online Slots Rules: How to Play Online

The beauty of online slots is that they're easy to understand. In fact, it's almost not worth asking how to play online slots because the mechanics are that simple. As long as you follow some basic slots rules (see below), all you have to do is set your bet and hit the spin button. Now, when it comes to slots rules, there really aren't that many. Two things you have to remember are to bet at least the minimum and that all wins read from left to right. Also, if you want to win a progressive jackpot, you'll have to set the max bet per line at your chosen stakes. Finally, any timeouts or technical glitches and the game will restart at the last previous spin.

Top Rated Online Slots Games 2019

Everyone has their own ideas about which slots games are the best in the business, but a few names crop up again and again.

Online Slots with the Biggest Progressive Jackpots

The online slot games with the biggest progressive jackpots are a top commodity in the UK. Casino sites offering these slot titles with the largest jackpots can draw in an unprecedented amount of new and returning players. Here is a list of the online slot titles offering the biggest progressive jackpots and who is offering them:

How Do Players Claim Online Winnings?

Claiming your winnings from a game is easy, especially when it’s a small prize. Any winnings earned during normal game play will automatically be added to your account and can be withdrawn to your bank account at your convenience but can also sit inside the account until more winnings are earned if players prefer to wait to withdraw it all at once. Players who win massive jackpots or uniquely large payouts will need to check the online operator’s withdrawal terms to confirm how much can be withdrawn at a given time. Some gambling sites require the player contact them directly for the larger winnings to confirm their identity and the legitimacy of the claim.

Random Number Generator (RNG) and How it Affects the Games

Online gamblers in search of the best games often come across references to a ‘random number generator’ but what is the RNG and how does affect the odds of the games? Random Number Generator (RNG) is software used for games of chance to generate a sequence of numbers, cards or symbols that cannot be predicted at a higher rate than random choice. So basically, RNG is the bedrock of the randomness of online slot, table and card games which solidifies the legitimacy and fairness of all the games. Without RNG technology, players couldn’t be assured the games were fair and random.

History of Slot Machines

Slot machine history starts with the infamous Liberty Bell. After experimenting with various mechanical spinners from 1887 onwards, Charles Fey finally rolled into life in 1895. Offering three reels and fixed payouts, this game essentially started a gaming revolution in the US, which eventually spread to the UK and Europe. Companies such as Bally Technologies came on to the scene a few decades later with a selection of video slots and by 1963 Money Honey made slots a digital affair. These video-based games then paved the way for the slots we know today.

In fact, were it not for these digital fruit machines, there might not have been an online slots history. Fortunately, thanks to innovations by companies like Bally Technologies, online slots finally came into being around the turn of the millennium. Since that time, thousands of titles have been developed by dozens of companies. In 2019, there are now more slot machines than ever before.
