Inter Milan attempted to sign of liverpool Curtis Jones in January. Although a deal fell through, they are still keen on the midfielder.

sports witness Covered how his exit from Anfield in the winter was dependent on renewals at the club. The Reds were offering him this but the midfielder refused, denying himself the chance to join the future Italian champions.

Since then, Jones has been a regular for Liverpool. He has started each of the last five games, being left on the bench only once since the end of January.

Inter depends on player efforts

Today’s Tuttosport – Go fcinternewsAccording to the report, Liverpool player Manu Kone is Inter’s option. While both players have different profiles, Christian Chivu is a big fan of the England player.

It is believed that Jones has had a ‘fall out with Slott’ and is still refusing to renew his deal at Anfield. The current contract expires in 2027, which could force the Reds to sell him this summer.

The Nerazzurri want to find out Liverpool’s asking price. This will help them evaluate the transfer in the best possible way, especially if a deal cannot be reached for Kone.

Willingness to leave is seen as positive

corriere dello sport Walk on the same path today.

He also believes Jones wants to leave the Merseyside club. This would help Inter get a better deal, as Liverpool would be forced to sell him.

The newspaper says that Cone and Jones are very different midfielders. This may cause confusion but Chivu remains a big admirer of the 25-year-old and that is what is driving Inter’s interest.

It is very difficult to see both midfielders coming in the summer. As a result, if Jones really wants to end up at San Siro, he may have to formally ask for an exit.

Our Opinion: Getting out of slots can be important

TuttoSport’s stance on the matter seems interesting. He feels Jones has a specific issue with the slot, indicating that the Dutchman’s exit could change things.

He is playing regularly and other than the manager he can have no other reason for leaving.

This suggests that Liverpool may still keep Jones. If the slot goes, the next manager will have to convince the Englishman of an important role in the project.

⭐Slot themes

Slot themes are the visual, audio, and narrative elements that shape the overall look, feel, and gameplay style of an online slot game.

Slot games today explore nearly every concept—from Egyptian tombs and Norse mythology to music festivals and fruit machines. A game’s theme affects not just the look, but the sound, mechanics, and even the paytable.

🎰 Learn how to win at slots 🎰

For example, Book of Dead immerses players in an ancient adventure with expanding symbols and high volatility, while Big Bass Bonanza delivers casual fishing vibes with free spins and wild features. Branded slots use slick animations and IP-based storylines. Whether you’re playing for the experience or chasing big wins, the theme can make or break how engaging an online casino game feels.

🎲 Everything you need to know about slot features

Modern online slots are powered by much more than spinning reels and flashing lights. While luck is always a factor, understanding how features like symbols, paylines, and bonus rounds work can help you make better choices and enjoy the experience more. Below, we explore the core mechanics that define every online casino game.

Slot symbols

Slot symbols are the building blocks of every spin. They determine wins, trigger features, and contribute to the overall gameplay.

11

Regular symbols

Regular symbols are the essential building blocks of any slot game, determining wins, triggering features, and contributing to the overall gameplay. These symbols typically consist of low-paying icons, such as numbers, letters, and themed images linked to the game’s design. For instance, in Big Bass Bonanza, regular symbols include fish, rods, and bait, while in Book of Dead, pharaoh masks and Egyptian artifacts take center stage. When players land three or more matching symbols on active paylines, they can trigger a payout based on the values in the paytable. Regular symbols provide the foundation for most wins and are crucial for players aiming to meet wagering requirements for bonus offers or free spins.

Wilds

Wild symbols act as substitutes for most other symbols to help create winning combinations. Much like jokers in a deck of cards, wilds can fill in the gaps in a player’s spin, increasing their chances of earning a win. Some wilds are sticky, meaning they remain in place for several spins, while others may expand across the reel or come with multipliers, which can significantly increase payout potential.

Games like Starburst feature expanding wilds that cover an entire reel, giving players a better chance to win big. In high-volatility slots, wilds can unlock significant payouts, especially when combined with features like cascading symbols or bonus rounds that include multipliers. Wild symbols are an essential part of many high RTP slots, such as those offered by Pragmatic Play and NetEnt, providing both a visual and gameplay advantage.

Scatters

Scatter symbols are typically the most exciting symbols in any slot game. Unlike regular symbols, scatters do not need to align on a payline to trigger a reward. They can appear anywhere on the reels and still unlock features like free spins or bonus rounds. For example, in Book of Dead, the scatter symbol, represented by the Book of Dead, unlocks free spins when three or more appear on the screen.

These bonus features are highly sought after, as they give players the chance to win without placing additional bets. Scatters are also often associated with cashback rewards or bonus funds, which are credited during Drops & Wins tournaments, providing players an added opportunity to earn prizes without extra costs.

Multiplier symbols

Multiplier symbols boost a player’s payout by multiplying the value of their winnings by a specified amount. These symbols often appear during bonus rounds or free spins and are instantly recognizable due to the large multiplier values displayed on them.

For instance, in Gates of Olympus, multiplier symbols can drastically increase winnings when they land on the reels, especially during time-limited tournaments or knockout tournaments where maximizing your stake is key. Multiplier symbols are a significant feature in high-volatility slots and provide a thrilling element for players looking to increase their win potential by taking advantage of these amplified rewards.

Bonus symbols

Bonus symbols are the heart of a slot’s most lucrative features, unlocking special rounds where additional features or larger payouts are up for grabs. These symbols often trigger free spins, pick-me games, or access to the progressive jackpots in games like Mega Moolah.

In Immortal Romance, bonus symbols unlock a special round with multipliers and additional spins, while in Big Bass Bonanza, players can trigger a pick-me bonus where they can win extra rewards. These bonus rounds are where the real excitement happens, offering the chance for larger payouts and increased stake opportunities, often tied to promotions such as cashback rewards or special bonus offers during live casino events.

Expanding wilds

Expanding wilds are a popular variation of the standard wild symbol, as they grow to cover an entire reel when they appear. This increases the chances of creating winning combinations on multiple paylines. For example, Starburst uses expanding wilds that stretch across the entire reel, offering the opportunity for big wins.

This is especially useful in high RTP slots, where players can maximize their potential payout. Expanding wilds work particularly well in games with cascading symbols, such as Gonzo’s Quest, as the expanded wilds can help trigger additional wins on subsequent spins.

Cascading symbols

Cascading symbols are a modern feature in many video slots and involve the removal of winning symbols from the reels, making space for new symbols to fall into place. This mechanic increases the potential for multiple wins from a single spin. For example, in Gonzo’s Quest, each winning symbol disappears, allowing new ones to cascade in, often triggering bonus spins or additional wins.

This feature is common in medium-to-high volatility slots, where players can accumulate a chain of wins within a single round, significantly boosting their chances of hitting a big win. Cascading reels are particularly effective when combined with multipliers, making them an exciting feature for players aiming to maximize their payout potential.

Paylines

Classic slots might have just a few paylines, while modern titles feature dozens—or even thousands—of ways to win. The more paylines a game has, the greater the chances of forming a winning combination—but it can also increase the minimum bet per spin. Some slots allow you to adjust the number of active lines, giving you control over both max bet and risk level.

Other ways of winning

Beyond fixed paylines, newer slots use systems like 243 ways, 1024 ways, and even Megaways, where the number of active symbols changes with every spin. In these setups, payouts are based on matching symbols in adjacent reels, starting from the left. These game mechanics are part of why slot selection has grown so diverse, especially across top-rated platforms like LeoVegas and MrQ.

Bonus rounds

Bonus rounds are what make online slots more than just repetitive spinning. These features break the core cycle and offer chances for bigger wins and interactive elements.

Free spins

Triggered by scatter symbols, free spins give you a set number of turns with no minimum wager deducted. Some deposit bonuses or welcome packages also include free spins, often valued at £0.10 per spin. Winnings may be subject to wagering requirements, so always check the t&cs.

Pick-me games

These are simple interactive features where you choose from a selection of hidden prizes. You might reveal instant cash, bonus rewards, or extra spins. Pick-me games are common in branded slots with rich graphics and slick animations.

Respins

Respins allow certain reels to spin again while others remain locked. They often appear in slots with expanding wilds or stacked symbols and are used to build tension or chase a bigger payout. Some games trigger respins after near-misses, giving you a second shot at bonus entry.

Average RTP

Average RTP (Return to Player) is a key metric when choosing real money slot games. For example, a slot with a 96% RTP will theoretically return £96 from every £100 wagered. UK Gambling Commission-regulated casinos must display accurate RTP data to ensure fair play.

Switched around, the house edge is 4% – the difference between 100% and the slot RTP. The higher the average score across a casino’s entire collection of slots, the more payout potential you can tap into.

The average RTP for slot games in the UK is around 96%. So, if a slot site has an overall ratio that’s below that, I wouldn’t recommend it to my players unless it had some extremely enticing features to offset that issue.

Software providers

Variety is the spice of life, particularly when it comes to casino slots. Every software provider creates unique features, themes and franchises. For example, NetEnt has licensed deals with movie studios and record labels.

Yggdrasil slots are known for their storybook themes, while Big Time Gaming has the ever-popular Megaways mechanic. Slot sites that have games from a wide variety of software providers typically offer the best overall experience.

Game variety

Quantity doesn’t automatically equal quality. However, the more choices there are, the better your chances of finding games you enjoy, including live casino games. As a standard, I like casinos to have at least 300 online slot titles.

Slots bonus

Top-end value matters when it comes to slots bonuses. For example, a slot sites with a welcome bonus that gives you 100 bonus spins is better than one that offers 10. However, I always tell players to consider the wagering requirements in conjunction with the max bonus. 

A great-looking offer can fall down if the amount you can win is capped at £5, or you need to wager 100x the value of your prize before making a withdrawal. Put simply, wagering requirements determine the true value of a welcome bonus and bonus spins promotions.

On top of the wagering requirements, a player needs to keep an aye on restrictions and t&cs when claiming bonuses. For example, player’s first deposit amount must meet the wagering requirements in order for the bettor to claim the bonus. Secondly, there might be payment method restrictions. For example, Casushi offers welcome bonus of match deposit and 20 free spins, however depositing with Skrill and Neteller will not meet the wagering requirements.

🎰 The most common slot types in UK online casinos

The variety of online casino games in the UK is driven by the sheer number of slot formats available today. Whether you’re chasing max wins, clearing a welcome bonus, or aiming for consistent cashback rewards, choosing the right slot type matters. Below is a breakdown of the most common—and most strategically useful—slot formats found on the best UK slot sites.

Classic slot games

Classic slots, sometimes referred to as 3-reel or traditional slots, mimic the layout of physical fruit machines. These games usually offer a lower number of paylines, a minimum bet starting around 10p, and straightforward gameplay with minimal features.

They’re best for players looking to fulfill wagering requirements slowly and steadily, often as part of a welcome package or loyalty scheme. While the graphics are simple, the random number generator (RNG) ensures fair play like any modern title. Examples include 777 Strike and Triple Diamond.

Video slots

Video slots are the most common format found on UK slot sites. These 5-reel games include interactive graphics, sound effects, and themed gameplay—ranging from mythology to pop culture. They typically feature bonus rounds, scatter symbols, and expanding wilds, offering a broader selection of rewards during regular play.

Titles like Book of Dead, Big Bass Bonanza or Starburst are often tied to free spins or deposit bonus offers due to their broad appeal and bonus-friendly math models.

Megaways slots

Megaways slots use a patented dynamic reel mechanic developed by Big Time Gaming that changes the number of paylines on each spin—often up to 117,649. These slots are typically high volatility, with cascading reels, random multipliers, and max win potential exceeding 10,000x your bet.

Big Bass Bonanza Megaways, Gonzo’s Quest Megaways, and Space Wars Megaways XXXtreme are just a few examples, featured at sites like Casumo, Mr Vegas, and sport BET. They’re ideal for players claiming welcome bonuses with higher max bet flexibility or for those who want to test volatility before committing larger deposits.

Jackpot slots

With progressive jackpot slots, every spin contributes a portion of the stake to a growing prize pool. These games are known for delivering life-changing wins, but often come with lower RTP scores and high variance.

Titles like Mega Moolah, Jackpot King, and Immortal Romance Mega Moolah can be found on sport BET, where players have access to over 50 progressive titles, including daily jackpot drops. Just be mindful: the path to those big payouts can be long, but the maximum win potential makes them worth a spin—especially with cashback rewards softening the risk.

High RTP slots

High RTP slots are games with return-to-player rates above the UK average of 96%. These games aren’t a formal category, but they deserve a mention due to their utility in bonus clearing, particularly on no-wagering sites like MrQ or Casushi.

Games such as Blood Suckers Megaways (RTP 97.66%) and Book of 99 (RTP 99%) are often featured in free spin packages, making them among the best options for players who want consistent returns during promos.

Drops & Wins slots

Drops & Wins is an exciting series of slot tournaments that offer players a chance to win prizes through both prize drops and tournaments. Players can participate in these events by playing selected slots games from a particular software provider, with wilds, multipliers, and other bonus rounds increasing the chances of hitting significant rewards.

The tournament structure usually involves tracking players’ progress through different levels and rewarding those with the most wins. With drops, players can earn random prizes as they play, giving a fun twist to traditional slot gameplay. Big Bass Bonanza and Book of Dead are popular examples where players can earn free spins and bonus rewards through Drops & Wins tournaments.

Slingo slot games (bingo slots)

Slingo is a hybrid between slot games and bingo, often refered to as bingo slots. The so-called bingo slots offer a fast-paced, grid-based experience that appeals to players looking for something beyond reels and paylines. Instead of matching symbols, you’re spinning to reveal numbers, aiming to complete lines across a 5×5 grid.

Each spin reveals a new set of numbers, and special symbols like jokers, free spins, or multipliers add layers of strategy. A full line earns you a prize, with additional bonus rounds often triggered during play. Slingo games are commonly low to medium volatility, which makes them ideal for players using welcome bonuses, cashback rewards, or chasing loyalty promos.

Popular bingo slots titles like Slingo Starburst, Slingo Rainbow Riches, and Slingo Deal or No Deal are now a regular part of the slot selection at UK casinos, often accessible with a minimum deposit or as one part of a package that includes traditional slots.

Due to their structure, bingo slots typically have lower max win potential compared to high-volatility slots, but they compensate with consistent gameplay, short session times, and better alignment with bonus wagering requirements. As always, make sure to review the t&cs, especially if Slingo games are excluded or limited in bonus contribution.

High volatility online slots

Slot volatility describes how often and how much a slot pays out—a key factor when choosing where to play. High-volatility online slots tend to pay out less frequently, but when they do, the payouts are significantly higher. This means longer dry spells, but a bigger chance of hitting a major prize when the wins do come.

Slot games like Big Bass Bonanza, Money Cart 2, and Gates of Olympus are excellent examples of high-volatility slots. They often come with bonus rounds, multipliers, and high max win potential—ideal for players chasing that one big moment. These slots are also commonly featured in Drops & Wins tournaments and free spin promotions across top-rated slot sites like Grosvenor Casino, LeoVegas and MrQ.

Slot volatility levels explained

Volatility isn’t just jargon—it helps you match your playing style to the right type of game. Here’s how it breaks down:

Low Volatility Slots – 🟢 Frequent wins, but smaller amounts. Great for casual play and meeting wagering requirements.
Example: Crystal Vault

Medium Volatility Slots – 🟡 A balance between risk and reward. Decent hit rate with moderate payout sizes.
Example: Book of Dead

High Volatility Slots – 🔴 Rare wins, but with huge jackpot or max win potential. Best suited for players using cashback rewards or bonus funds.
Example: Big Bass Splash, Money Cart 2

High-volatility slots usually have more complex mechanics—like expanding wilds, cascading reels, or cluster pays—which can lead to massive payouts in a single spin. While the RTP might be similar across all volatility levels, your gameplay experience and bankroll swings can differ dramatically.

Whether you’re playing with your welcome offer or chasing prizes in a slot tournament, understanding volatility levels helps you make smarter decisions and enjoy more tailored slot sessions.

Branded & feature-rich slots

Branded slots are built around licensed themes from movies, music, or sports. They often come with multi-level bonus rounds, animated cutscenes, and slick designs that appeal to casual and competitive players alike.

Although not always the best for RTP, they’re frequently included in slot tournaments and promos, where engagement and game familiarity are key. Examples include Narcos, Rick and Morty Megaways, and Jimi Hendrix.

📱Best casino software providers for slots

💡Our top 5 tips for playing online slot games

There’s no guaranteed way to win at online casino games, but a smart approach can stretch your budget and improve your chances of landing meaningful wins. Whether you’re chasing a welcome bonus, trying out a new title, or entering a slot tournament, keep the following tips in mind:

Don’t overuse the max bet function

Using the max bet button can lead to fast wins—but also faster losses. Some t&cs even restrict max bets during bonus play. Unless your strategy and budget allow for it, avoid defaulting to max bet, especially when meeting wagering requirements tied to deposit bonuses or cashback rewards.

Play according to your gambling budget

Before spinning any reels, set a clear minimum and maximum budget for the session. The best slot sites offer responsible gambling tools to help manage spending. Remember: slot play should be entertaining, not stressful. Stick to your limits, and don’t chase losses just to recover a past result.

Try out demo slots

Many top UK slot sites let you play demo slots without spending real money. This is a great way to test features, bonus rounds, and paytables. It’s especially useful when exploring new slot types like Slingo, branded slots, or high-volatility games—without risking your bankroll or bonus eligibility.

Read the paytable

Each slot’s paytable shows how symbols pay, how many paylines are active, and whether features like wilds, multipliers, or free spins exist. It may also outline the maximum win or jackpot potential. Understanding the paytable can help you evaluate a game’s selection of rewards before placing real-money bets.

Pick slots with suitable RTP and volatility

A slot’s RTP and volatility impact your experience more than flashy graphics. High-RTP slots (above 96%) are great for bonus clearing and consistent slot wins, while high-volatility games suit those chasing bigger payouts. Match the numbers to your goals, whether you’re playing for fun or aiming to beat the wagering requirements.

🏆Online slot tournaments

If you’re the competitive type, slot tournaments offer a thrilling twist on standard spins. As discussed earlier, tournaments pit you against other players to see who can rack up the most wins or points during a set timeframe.

🔎Laws and regulations regarding online slots in the UK

I only recommend slot games, casino bonus offers and payment options, such as PayPal, which comply with UK Gambling Commission regulations. These regulations ensure every aspect of your online gaming experience is safe, legal and fair. 

Some of the regulations UK Gambling Commission-licensed casinos must comply with are:

• Verified RTP and RNG technology: The UK Gambling Commission doesn’t impose minimum RTP values, but software providers and casino operators are required to display a game’s RTP. Additionally, the RNG (random number generator) technology that powers a game must be certified as fair by an independent organisation such as iTech Labs. 
• Safety and security: All slots and casino platforms must provide secure software. Additionally, data must be encrypted and payments processed by approved processors. 
• Payouts: All winnings and casino bonus payments must be honoured in accordance with an operator’s terms and conditions. 
• Responsible gambling: Legal UK online casinos are required to provide responsible gaming tools, including customisable betting limits and timeout options. 

The message here is simple: protect yourself and your bankroll by sticking to UK slot sites that are licensed by the Gambling Commission. 

📌Conclusion

The UK online slot market offers something for everyone, whether you’re into traditional games or new high-volatility options. By opting for casinos licensed by the UK Gambling Commission, you ensure a safe and secure environment.

Prioritize RTP, generous bonuses, and mobile optimization when selecting your site. Whether you seek big wins or fun features, there’s plenty to explore, and with a responsible mindset, the rewards can be great.

UK best slots FAQ

1. How many paylines do online slots have in the UK?

The number of paylines vary greatly between online slots. Players in the UK are in a position to bet on classic slots, featuring just a single payline. Meanwhile, Megaways slots can feature as many as 117,649 paylines. While it is nice to know how many paylines are available, it should not be the sole reason for playing a particular slot. 

2. What welcome bonus is the best for slot players?

When signing up at an online casino, if you have your eyes on the best slot games, then here are the bonuses you should look out for:

3. Which online slots have the highest payouts in the UK?

Book of 99, 1429 Uncharted Seas, Blood Suckers and Jokerizer are among the best in this area, coming with an RTP of 99%, 98.6%, 98% and 98%, respectively. 

4. Which slot game developers make slot games for UK online casinos?

We have recommended slots from a host of developers, of which the most belong to Games Global, NetEnt, Pragmatic Play, Big Time Gaming and Play’n GO. Such software providers are known for creating entertaining, rewarding and visually pleasing slots. 

5. Can you play slots on mobile?

The majority of their best slot games are accessible on mobile. HTML5 technology is used in most cases. This means that players can place bets on their favourite slots using their smartphone or tablet with ease. Meanwhile, all of our top-ranked mobile casinos are mobile-friendly, with many coming with a downloadable app.

6. What are loose slot games?

A loose slot is one that generally pays out more than another. While the house edge is still with the casino, loose slots will appeal to many players. Loose is another word for the term low volatility, meaning more regular payouts at smaller amounts. 

The majority of slots available in the UK today feature either medium or high volatility. However, it is certainly still possible to find low-volatility games, also known as loose slots. Examples include Starburst, Enchanted Garden II, Bloodsuckers II and Wild Scarabs. 

7. Are online slots for real money?

Yes. The majority of slots at UK-licensed casinos are real-money games, meaning players must deposit funds to place wagers and are eligible for cash winnings. Many slot sites also offer demo modes for practice, but real payouts are only possible when playing with real money.
