How To Play Online Slots

Before you load up any online slot game, you should evaluate whether you can afford to play it. What we mean by this is whether the stakes or bet are achievable for your budget; the minimum bet per spin may be out of your price range. Every slot game offers a minimum and maximum stake, and some may be suitable and some may not because your bankroll will be swallowed up before you see any real wins come in.

As an example, ff a game has a minimum bet per spin of £1 and your budget is £10, then this type of slot isn't recommended as your balance will be swallowed up pretty quickly. The trick is to start small and increase your stakes (if on a winning streak) or increase levels if you’ve built up substantial winnings. Keeping your stake amount low will also ensure your bankroll lasts as long as possible.

All slots can appear the same from the outside looking in, but despite a great theme and amazing in-game features there's a lot of differences behind the pretty HD graphics; understanding minimum and maximum stakes is the first step to understanding online slots a bit better. The next important aspect to understand about slots online is its RTP % and variance:

Understanding Slots RTP % & Variance

Every casino game and slot has an inbuilt RTP % which stands for "Return To Player %". A slot RTP is the percentage given back to players from a slot over a period of time. All slots have a house edge or margin and the RTP % determines what's won back. To help explain how RTP's work, here's an easy example:

Let's say a slot game has a 96% RTP. If you were to hypothetically stake £100, you’d win back £96 on average and the casino would gain £4 (the remaining 4%). However, it is critical to keep in mind that the RTP % is generic and don’t necessarily apply to your game session. A game RTP % is calculated over millions of spins. The RTP % reflects the course of a slot’s cycle (which is normally 1 year), that it will pay out the advertised amount. There are third-party testing labs, which are UKGC compliant that test and make sure games payout their stated RTP%'s at UK online casinos.

A slots "variance" is something a bit different to RTP % but still important to understand. When we talk about slots variance, we mean the risk involved in the slot game. Usually, a slot is considered a ‘high variance slot’, a ‘low variance slot’ or a 'medium variance' (which sits nicely in the middle of low and high). Slot variance is can also be called slot Volatility.

The variance of a slot will affect your gameplay and potential payouts as it denotes the frequency of winning combinations. Here's a brief overview of each type of slot variance and how they are designed to affect the outcome:

  • High variance slots: High variance slots are usually considered high-risk but high-reward online slots, where wins can be less frequent but when they hit, they can be huge. Experienced slots players tend to prefer high variance slots as they usually chase big rewards and life-changing payouts only available when you play high variance slots. Top examples of high variance slots include Dead or Alive 2 (Netent) and Starburst XXXtreme Slot (Netent).
  • Medium variance slots: Medium Variance slots are, without sounding too obvious, are medium risk and medium reward games. Top payouts in these games can be decent and show up pretty frequently. Medium variance slots are well-balanced and compatible for all types of players.
  • Low variance slots: Low variance slots are games that offer players a low risk but low reward. Expect to see lots of wins but smaller in reward. You can win big in these games but it's highly unlikely that they will pay out big regularly. Low variance slots are the perfect mix for those who are new to playing online slots or those with a smaller, modest budget. A great example of a low variance slot is Netent's Starburst Slot.

Best UK Online Slots

The topic of online slots is huge; there are thousands of premium slots games available from an array of different game providers. From the pioneers who gave us the first online slots a few decades ago (Microgaming) to the many other than each bring their own style and innovation to the table.

The most popular slots in the UK are provided by a long list of game studios which include Netent, Microgaming, NYX, Play 'N Go, Elk Studios, Quickspin, Yggdrasil, No Limit City, Gameburger Studios, Hacksaw Gaming, Slingo Originals, Big Time Gaming, Tom Horn Gaming, Eyecon, Gold Coin Studios, Gamevy, Barcrest, IGT and NextGen. The list could go on.

Thankfully, many online casinos in the UK have all of the top software providers integrated into their site so that you can access the best slots and the newest slots online, all from one casino and one account.

Below you'll find the most common types of online slot games available at online casinos. We explain the differences between the types of game and what they mean:

Classic Slots

Classic slots are considered the 'originals' when it comes to online slots. They are what slots started as, and are loosely based on land-based fruit machines you'll find in Pubs and Arcades. Classic slots typically have 3 reels and 1 single payline. A win can be formed by getting 3 matching symbols across the middle of the screen. Newer classic slots usually offer the original concept, but newer features include free spins and bonus games.

Video Slots

These are the most common type of online slot and normally incorporate 5 reels, however, some newer slots offer crazily designed reels, colossal reels and the latest innovations. Most online slots fall into the video slot category and will be packed full of entertaining bonus features like free spins, wild symbols, scatters, multipliers and bonus rounds.

Jackpot Slot

These are typically video slots that offer a progressive jackpot prize. Progressive jackpots allow players to win mammoth jackpots which can reach 7 or 8 figures on some slots Microgaming’s Mega Moolah, which paid out a world-record €19.4 million in April 2021.

Mobile Slots

Mobile slots are online slots that can be enjoyed on mobile and tablet devices. Many new slots and older, popular slots are available (with the latter being adapted with modern HTML technology) to give players the chance to play their favourite games on the go. No matter which is your preferred operating system - iOS, Windows or Android, mobile slots can be loaded up in your mobile browser to be enjoyed on the go without any compromise. To get the best mobile slots experience, make sure you play at the best mobile casinos UK.

Themed Slots

No matter the theme, we're in no doubt that you'll find a slot version of it! Themed and branded slots will fall into the categories above, but some players like to play certain themed slots, such as Egyptian, Greek Mythology. Super Heroes, Dragons, Mythology, Movie, and Cartoon themed - the list goes on!

Megaways Slots

Megaways are a new type of slot game from the Australian casino game powerhouse Big Time Gaming. Megaways slots are played with up to 6 reels where the number of symbols on each reel changes with each spin. What happens next is the number of potential ways to win changes randomly with each spin. The more symbols to display per reel, the more Megaways paylines will be created. So popular are Megaways slots, that BTG has collaborated with many other game studios to create many different kinds of Megaways slots. You will be able to find Megaways slots at top online casinos in the UK.

Slingo Slots

Slingo slots combine the best elements of online slots and bingo! Slingo™ games are one of the greatest innovations of recent times and are available in droves at most casinos online. Popular Slingo games include Slingo Starburst, Slingo Advance, Slingo Deal or No Deal, Slingo Centurion, Slingo Lobster Mania and Slingo Britains Got Talent.

Free Online Slots

We all love to play online slots, but sometimes you will want to give a new slot a test drive first. There are some free slots (demo slots) available when you log into UK casinos. We recommend playing slots for free before you dig into your own pocket and play for real money. Playing free online slots allows users to test the slot first to get a feel for how the game works. Playing free slots online will also allow you to see the graphics and animations and try out the bonus features for free. Free slots will help you make your mind up before you play with your own money.

Another way to play free online slots is to grab a free casino bonus. They are harder to come by at UK casinos, however, some UK casino websites do offer free spins no deposit on your registration. These are great because the casino will give you a real casino bonus to play slots and casino games without you having to trump up with your own money first.

Not all casinos online offer no deposit slot bonuses, however, if you compare the list of casinos above, you will be able to see which ones do. From there, simply create a new account, claim the free bonus and play some free online slots. If you're happy with your choice, and you're happy with the slots that you've just demoed, top casinos will also give customers a high-value match deposit bonus on their first deposit.

Slot Game Providers

As mentioned above, there's an umpteen amount of game providers available at online casinos.

Luckily for you, we have done all the work so you don’t have to! Above is a handpicked selection of trusted slot sites and UK casinos that have passed our rigorous tests here at UK-OnlineCasino.org.uk.

What are Wager and No Wager Free Spins?

These are a type of casino bonus playable on slots. Wagering free spins come with a wagering requirement on any winnings derived from using them, whilst those that are wager-free do not.

Slots RTP stands for "Return to Player." RTP % indicates the expected payout to players which is given theoretically over an infinite amount of game rounds/spins of the game.

This way, when you play at UK online casinos that are UK Gambling Commission licensed, you know you will be playing fair and unrigged slot games.

What Online Slots Are The Best To Play?

This ultimately depends on what you like playing as a player. Every slots player is different. Some players like classic 3 reel slots, some enjoy free slots only, some enjoy playing Megaways Slots, Monopoly Slots or Rainbow Riches Slots and some enjoy slots only from a specific game provider. Popular slots and the latest slots to launch in the UK are all available at our recommended slot sites in the list above. We're sure you will find plenty of slots that you'll enjoy plus new games to try out.
