Online Slots UK 2023

The selection of online slots has increased massively in recent years, from the classic 3-Reel to the more exciting 5-Reel slot machines, with unique features and multiple pay lines. As technology improves, software providers continually look for new ways to entertain players. They invariably offer a rich experience for a generation of players brought up with video games.

New & Popular UK Slots 

There are hundreds of new slots released every day, yet not all become famous. UK players get a vast collection of new slots by renowned game developers. Although it isn't easy to pick just three, these mentioned below are newly released slots online to win real money. We can thank the amount of premium new slots for paving the way for many new slot sites popping up in the UK

Egyptian Fortunes is a stylish Pragmatic Play slot release with 5-reels and 20 pay lines. The Egyptian theme takes you right into the heart of the magnificent pyramid, where you descend into the Pharaoh’s tomb in search of treasure and wins. The features include Energy Spins, whereby certain combinations activate the attractive element. Pirates Gold is a classic best UK slot released by NetEnt with many pirate booties to claim! 

Although somewhat different from typical NetEnt releases, the game is entertaining to play and offers fantastic payouts. With so many top-notch slots, it’s hard to pick out a few, yet these slot titles are among the best UK slots. One title deserves a special mention. Starburst is undoubtedly one of NetEnt’s most popular and endearing releases in recent years. Starburst uses a "Win Both Ways" game mechanic, providing winning combinations with both ways. Whenever the magic Starburst icon lands on your reels, it replaces others and activates the ReSpins.  

3-Reel Slots

3-Reel slots are primarily based on the classic, original Fruit Machine games in arcades worldwide. The purest form of online Slots games, 3-reel slots are easy to understand. A window shows three columns and three rows of symbols. 3-reel slots are a gentle and straightforward introduction to online slots. As you get more experienced, you can move on to more complicated slots, but will often return to 3-reel games as a form of pure, non-energetic relaxation!

5-Reel Slots

Known as video slots, 5-Reel slots are a more elaborate form of the game. Rather than just one pay line, 5-reel slots can have up to 100! That serves up many additional winning combinations, giving you a better chance of winning a payout. 5-reel slots also include special features such as wilds and scatter symbols to give you even more chances to win! Betting on 5-reel slots becomes more complex as you bet on each of the pay lines, so a £0.10 stake costs £5 a spin if you choose to bet on all 50 pay lines, and you need to have a decent bankroll management strategy

Bonus Feature Slots 

Bonus slots offer unique features such as extra free spins and bonus rounds unlocked via Wilds and Scatters, random symbols that act as wildcards, giving players many more chances to win on each spin.

Progressive Jackpot Slots

Usually, each slot game has a fixed jackpot which is individual to the game. With a progressive jackpot, every player playing the slot at whatever casino, wherever they are in the world, is playing for a steadily increasing prize. Every time someone plays, that jackpot increases. The games are sometimes linked, so the more players play, the higher the jackpot rises. Once the pot has been won, it resets and starts again. Such games can provide you with high payouts, and the largest recorded Progressive Jackpot payout was £11.8 million on Mega Moolah.

Other great jackpot titles include Lucky Leprechaun, Fruit Fiesta by Microgaming, and Mega Fortune by NetEnt. Lucky Leprechaun is another favourite that never fails to serve up twists and turns with high potential for a massive payout. Fruit Fiesta is a somewhat traditional slot which entertaining to play, providing high payout potential. Mega Fortune is renowned for its appealing qualities and substantial progressive jackpot payouts. Find out more about Progressive jackpot slots here.

Common Online Slot Features 

Bonus Games

Bonus games come in many forms and give you a chance to win extra payouts by playing the feature game. Bonus games are usually awarded when you line up certain symbols on the reels, and last for a short period before returning to the base game. Some bonus games feature sophisticated graphics, while others are simpler. Some require skill, while others are entirely random.

Free Spin Rounds

Free spins are a popular bonus feature which provides extra spins that boost your wins. A free spins round may be triggered in several ways, such as when specific symbols line up in a row on the reels. You are awarded free spins, and any winnings will stack up as you watch the turns revolve around the reels, one of the simplest and most common bonus rounds on slot games.

Scatter Symbols

The general rule of slots is that you have to line up certain symbols on a pay line to gain a win. This rule does not generally apply to Scatters, which is why they are sometimes called a player’s most valuable friend. They can appear on any reel and reward you with a win, or open up the bonus features such as free spins.

Wild Symbols

Wilds work like a joker in a deck of cards, and they can replace other symbols to complete a winning pay line. If you have 4 matching symbols and a wild symbol along a 5-reel pay-line, you are paid out as if you had 5 identical icons. Slot developers have experimented with various ways of using Wilds in their games, and they come in many forms, such as expanding wilds, shifting wilds, sticky wilds, cascading wilds, and stacked wilds.

Cascading Reels

Cascading Reels are an alternative to how slots work. Instead of a regular set of reels, the symbols cascade down to make room for a new selection, and any winnings also cascade down or disappear, allowing further icons to cascade and fill all the empty spaces!

Pay Lines

The pay line is the row upon which matching symbols must land to generate a win. The single pay line is the central row along the three reels on traditional three-reel slots. Your stake for every spin of the reels is split between pay lines, so if you are playing a 20 pay line slot machine, your stake will be 1 unit per pay line. Most slots allow you to select the number of pay lines you wish to play, and the amount you want to bet on each line.

Ways to Win

Some slot machines are developed with hundreds of ways to win across the reels without necessarily hitting traditional win lines. These kinds of slots are referred to as 243 or 1024 ways to win slots. Rather than the conventional straight pay lines from right to left, such slots payout no matter where your symbols appear.


The paytable is easily accessible from the main screen and provides crucial information about the slot, including the scatter and wild symbols, the payouts for winning combinations, and details of how bonus features are accessed.

Multiplier Symbols

This kind of symbol multiplies your winnings by a certain amount. They can range from a 2x multiplier up to 100x and 1000x multipliers, and depending on each game. They come in different forms, with some standard reels while others are only part of a particular feature or bonus game.

What are the Highest Paying Slots & What Does Slots RTP % Mean?

How can you find your favourite slot game? Do you play products by a specific slot developer? Or games with a particular theme? Perhaps you are looking for bonus features? Some players take advantage of a slot's high Return to Player rate. The UK best slots with high RTPs include the following, but a comprehensive list of the highest paying slots can be found here.

RNG Slots

Are slots legit? Random Number Generators (RNG) make the reels spin randomly and independently from the previous spins. When you press the start button, the RNG generates a unique number determining the eventual outcome of the turn. It is near impossible to predict the result of a spin. The games at online casinos are invariably checked by external testing agencies, with eCOGRA one of the more reputable ones. You can be sure that online slots are legit and hard to tamper with.

Slots Tournaments 

Slots Tournaments have become a popular feature at online casinos. You can find all kinds with various betting limits. The freeroll slot tournaments are the most popular of all, and some tournaments with buy-in fees go towards the pool. You can enjoy competing against other slot players for the coveted top position on the leaderboard.
