Types of Slots Online for Real Money in the UK

One of the joys of slots is that there are so many genres, themes, and variations. Each slot variant comes with its own design, mechanics, and features that affect how the game plays. In this segment, our experts have detailed six of the most common ones you will find at the best online slot casinos.

Three-Reel Classics

Simple slots online for real money that UK players can find at some casinos. These variations offer traditional symbols and straightforward gameplay. Whilst they are not as popular as they used to be, there is a fan-base that enjoys the nostalgic and simplified gaming experience with commands such as spin, hold, and nudge.

Multi-Reel Slots

A slot variant that offers players the opportunity to spin multiple reels on an enhanced grid. These games usually consist of 6 reels or more and usually offer a larger number of rows and paylines. Multi-reel slots can also have two sets of reels, both of which spin and can create winning combinations in the same round.

Video Slots

The majority of the best slots to play for real money at UK casinos fall under this variant category. They are among the most popular games played online and provide a modern gaming experience that is immersive and entertaining. This is in-part due to the advanced graphics, slick animations and thrilling bonus features they offer.

Progressive Slots

Progressive jackpots are slot games that pay real money in the form of a jackpot, alongside their usual multiplier prizes. The jackpots increase in size as bets are placed. This game variation means they have a prize pool that can be limited to a single game, or spread across a network of different slots. Each time you place a bet, a percentage of it will be put towards the jackpot prize.

Megaways Slots

Over the past ten years, the Megaways mechanic has been a part of the best slots to play online for real money. Variations developed with this feature offer an incredible number of ways to win (up to 117,649). The number of symbols on each row can vary with every spin, paving the way for tasty combinations of paylines and an unpredictable dynamic experience.

Other Online Slots

You can play slots online for real money in many other ways at the best international casinos. As the genre continues to grow, the industry is witnessing the popularity of other variations. These include 3D slots, VR slots, live game-show slots, and slots with cluster-pays, where you can match 4+ symbols anywhere on the grid.

Types of Bonuses for Online Casino Slots

There are different types of bonuses you can claim at online UK slots casinos. Each comes with its own qualities and benefits that you can use to enhance your experience. Below are some of the most popular offers found at the best slots platforms.

Welcome Offer

When you visit any of the top 10 best online slots casinos, you will find a welcome offer that is awarded upon signing up. This the very first bonus you can claim as a new player and will allow you to benefit from an immediate boost to your credits.

Some welcome offers are single-use deals, whereas others can be redeemed over multiple deposits or as part of a package. We recommend reading the terms and conditions for a welcome offer before making your first deposit in order to have all the info.

No Deposit Offer

One of the most sought-after bonuses in the industry. Play free slots with no deposit and keep winnings made from your gameplay. You do not need to spend any money to redeem these promotions and they are a great way to try out new games.

Bear in mind that these offers generally come with a cap on the amount you can withdraw, subject to wagering requirements. No deposit bonuses can be available for signing up, taking part in promotions, or simply for being active on the UK slots online casino.

Free Spins

Spin real slot machines online for free with bonus spins offers. Many top casinos provide a set number of free spins to use on one specific game. This may be as part of a new-game release or a popular title like Starburst. Whereas others allow you to choose from a selection of slots as outlined in the operator’s terms and conditions.

Free spins are usually played at the minimum bet, but you can also benefit from super free spins, or mega free spins, that are at higher stakes.

Reload Bonuses

When you make a deposit to your account, you can claim extra credits to use on your favourite real money slots. Reload bonuses work in a similar way to welcome offers, or first deposit bonuses, whereby the casino will match your deposit with a percentage of extra funds.

At the best casinos, reload bonuses typically vary from 50% to over 200%, up to a specified amount.


Cashback, sometimes referred to as a rebate, is a type of promotion that gives you a percentage of your money back to use again. When you play online slots for real money in the UK, you will be able to track how much you have won and lost between a set time period.

Bonuses with cashback allows you to recoup some of your losses in the form of free funds, such as 10% of your weekly loss amount.

5. Look at RTP and Volatility

5. Look at RTP and Volatility

When you gamble on online slots, you will notice that each game indicates an RTP (Return to Player) ratio. This value is a theoretical percentage that tells you how much is paid back to players over a period of time.

Volatility is also a metric used to determine the type of gameplay you can expect in relation to payouts. The higher the volatility level, the less frequently a game will payout, but the wins will be bigger when they land.

6. Use Demo Free Play Mode

6. Use Demo Free Play Mode

Many of the casinos with real money online slots in the UK offer demo versions. You can play each game in free play mode before risking any of your own money. This lets you not only familiarise yourself with the slot paytable, but also learn how to play slots and practise your gameplay or strategy.

How Do Online Real Money Slots Work?

When you play UK online slots for real money, there are a number of different features and mechanics that come together to make the game what it is. Whilst there are some variations between certain games, most slots have a consistent architecture that serve as the foundation pillars of the game.

PaylinesScattersWildsBonus RoundsMultipliers


Paylines are preset patterns on the slot grid that symbols must appear in a combination to trigger a payout. They typically pay from left to right and the number determines how you can win. This includes horizontally in straight lines and diagonally. Some of the best online slots have thousands of paylines, giving you more opportunities to win.


Scatter symbols are a special type of symbol in real money slot machines online and mobile. They are sometimes referred to as the bonus symbol, due to their ability to trigger the game’s bonus round. In a standard video slot, landing 3+ scatters is how you enter the free spins mode.


Wild symbols are present in almost all real money slots and substitute every other symbol except the scatter. This includes both the low-paying and high-paying symbols within the game, giving you more chances to land winning symbol combinations.

Bonus Rounds

Many people play slots online for real money with the aim of triggering the bonus round. It is a separate game within a game that typically offers enhanced payouts. Whilst the majority of slots have a bonus round with free spins, some offer unique modes such as a picking-bonus, online slots gamble feature, or board-games.


As the name would suggest, multipliers can multiply the payout from a combination, spin, or even from the entire bonus round. You can find multipliers added to wilds, which double or triple the payout they help create, for the free spins, thus winning several times more than usual, or for other features.

Volatility and RTP

Earlier in our guide to the best online casinos for slots, we touched on the importance of checking volatility and RTP. They are two of the biggest factors in calculating the slots odds in relation to payouts.

RTP stands for Return to Player ratio and is represented as a percentage. It shows you how likely a game is to pay out, if played continuously over a set period of time.

Generally, real money slot volatility comes in three main forms, including low, medium, and high. There are also slight deviations and crossovers between two values, such as low-medium. Ultimately, the lower the volatility level, the more frequently you will land wins. However, they will typically be on the smaller side compared with higher volatility games.

Payment Methods at UK Slot Casinos

eWallets like Neteller, Skrill, and PayPal are common at UK casinos with real money online slots.

Whilst this method is still fairly new to the UK market, it is becoming increasingly popular due to offering enhanced privacy and low fees. It is found at some top fast withdrawal UK casinos and can also be used for claiming online casino free spins plus other bonuses.
