Online casino slots cover all types of games. They have evolved over the years to include amazing graphics, professional soundtracks, and astonishing features, including life-altering potential wins. Nowadays, online slots come in many different shapes and sizes and cater to many kinds of player preferences.
Here are some of the popular types of online slot machines.
Classic slots are a nostalgic glimpse to the past. These games are inspired by the traditional mechanical slot games with a straightforward reel layout. Familiar symbols, like cherries, bars, and sevens, are a common sight on the reels of classic slot games.
Most classic online slot machines are an excellent option for beginners to get to grips with what slots might offer. Obviously, there are many experienced players who prefer the no-frills approach to their gaming.
Classic slots, like Fire Joker, tend to have extremely fast-paced gameplay and simple mechanics wrapped in a retro vibe, but they might include a more modern feature like progressive jackpots.
Megaways Slots have innovative mechanics, varying symbol sizes, and more volatile gameplay than average slots. Big Time Gaming developed the Megaways concept, which includes a ground-breaking format that can offer up to hundreds of thousands of paylines.
Players can easily recognise a Megaways slot game from its dynamic reels, and the best Megaways slots include various features, like cascading wins, expanding symbols, and multipliers.
The first big Megaways game was Bonanza Megaways, which still holds well today. For a little variety, you can also try Buffalo King Megaways or Big Bass Bonanza Megaways.
Jackpot slots are online slot games that can reward players with life-changing payouts. The games contain jackpots of varying sizes, with the biggest ones measured in millions of pounds. Legendary games like Mega Moolah have broken records with their huge jackpots.
The lure of a huge win from the best jackpot slots included in our game ranking has meant that the games have become very popular. Throw in some engaging gameplay, immersive themes and graphics, and exciting soundtracks, and these slots will keep players on the edge of their seats.
While providers have swayed away from massive progressive jackpot slots, there are still some new games popping up. Famous progressive jackpot slot Divine Fortune got a Black version in 2025, which changed some visuals and uses fixed jackpots.
Penny slots provide a perfect way to enjoy online gaming without breaking the bank. Playing penny slots online can help novice players get the handle on online casino games with very low stakes, as you only bet a penny per payline.
Penny slots strike a nice balance between affordability and entertainment. While the low bet level makes the games accessible, they can still feature vibrant graphics, bonus rounds, and even jackpots for a full gaming experience. As a game can have numerous ways to win with each spin, the cumulative spin bet can be more, even if the stake for a single payline remains one penny.
Games like Starburst have previously allowed you to play with as little as 1p per spin, but not any more. Now, you have to pick all paylines, which means a single spin is 10p.
Grid Slots have become increasingly popular as providers have been trying out fresh ideas. These games have a grid of symbols instead of reels.
The grid feature is a top-level mechanic, meaning the slot can have other features on top of that. The symbol grid might be cascading or have scatter pays, but it always follows the same structure.
The most common size of Grid slots is 6x6 symbols, which is in Le Bandit and Money Train 4. The grids can be as big as 8x8 in Star Cluster Megaclusters or 9x9 in Cash of Command and Dragons Clusterbuster.
Cascading slots have become popular among players due to their innovative gameplay mechanics. Instead of a single spin that decides a win, the cascade feature can offer several wins in a row, as winning combinations are removed and replaced with new symbols.
It is the dynamic and engaging gaming experience of cascading slots that has caught the attention of players. Games like Gonzo's Quest from NetEnt can rack up multiple wins with the added excitement of multipliers. Like many other types of slots, the animations and themes in modern cascading slot games are often top notch.
Multiplier slots are an excellent game choice for players who enjoy seeing their wins amplified. Multipliers bring extra excitement to spinning the reels and can boost payouts dramatically. For example, the free spins round in the Chaos Crew slot features a growing multipliers symbol that can go up to 10,000x your bet.
The multiplier slots have different ways of implementing the multiplier feature, such as Wild symbols, cascading wins, or the free spins feature. Some game stack multipliers for potentially breathtaking wins.
Single line slots are a fairly unique type of slots which take inspiration from the older Vegas-styled slots. However, they are not limited to only being classic slots, and there are numerous modern single payline slot machines available in the UK.
The core idea of all these slot machines is that you can only win from one payline. The number of reels can vary, and there are even slots with one single reel that also have just one payline.
For example, Emerald Diamond is a slot single line slot game that even looks like a physical machine. Halloween Luck, on the other hand, has just one reel with one visible symbol.
Generally, single line slots are lower in volatility and have fewer special features. They are often built around one feature or mechanic and very rarely have multiple bonus functions.
Scatter Pays slots take the idea of paylines and throw it away. These games pay out no matter how the symbols are lined up on the screen. Some may require that the symbols are touching, but not all.
Scatter Pays games have many similarities with grid slots, but they are not the same. Some grid slots use scatter pays mechanics, but you can find scatter pays slots with regular reels.
Perhaps the most popular scatter pays slot is Pragmatic Play's Sweet Bonanza. It popularised the concept of not having paylines, and just having the symbols somewhere is enough.
When you compare online slot games with physical slot machines, there isn't really any competition. Online slot games offer numerous benefits, from better mechanics to bigger wins.
Here are the top benefits of playing slots online:
Themes play a big role in slot machines. Stunning visual design, enticing soundscape and thrilling storylines can bring so much to a slot game. Finding your preferred themes can help you play more interesting games with features you like.
Here are just some of the popular slot themes you can find in UK online casinos.
Fruit slots are a blast from the past. These games feature traditional fruit symbols and mechanics that were common in physical slot machines you would find in pubs and casinos. They are often simple games and great for beginners.
These slots take inspiration from ancient mythologies and tales, including Greek Gods, Norse conquerors, and even dragons and magical beings. Games in this category are often very thematic and focus on the visual side.
While Ancient Egypt is a theme that could be a part of Mythology-themed games, it is so popular that it deserves its own category. Egyptian history, both factual and fictional, is very common in slots. These games also have clever game mechanics that support the theme.
Slot providers have adapted many classics of the silver screen to online slots. These games feature familiar characters, themes and even music from the movies. All the special features in them are also themed after what happens in the film.
Online slots are no strangers to delving into the macabre. Horror-themed slots have creepy designs, eerie music and chilling features. If you don't want to be spooked, there are also fun horror slots with a comical twist.
Bright colours and playful visuals are the name of the game in candy slots. Common features in these games are cluster mechanics, volatile gameplay and cascading symbols.
Natural themes and animals are popular bases for online slots. From fishing to stampeding buffalo, from kings of the jungle to kings of the forest, animals play a huge role in slot themes.
Irish mythology and themes are commonly associated with luck, which means they are a gambling staple. Four-leaf clovers, pots of gold, rainbows and leprechauns can all be found in numerous popular online slots.
Enjoy chasing treasures and trying to find your way through ancient ruins? With these online slots, you can join a daring adventurer and hunt down ancient treasures buried in lost and dangerous places.
The best paying slot games have one of the biggest pull factors of online casino games: they have the best return-to-player ratio, or RTP for short. The higher the RTP of a game is, the larger portion of the money played is returned to players and the better paying the slot is.
You can see the best UK-licensed RTP slot games below:
| Rank | Game | RTP | Provider |
|---|---|---|---|
| 1. | Money Carlo | 99.99% | Storm Gaming |
| 2. | Mega Joker | 99% | NetEnt |
| 3. | Book of 99 | 99% | Relax Gaming |
| 4. | Jackpot 6000 | 98.9% | NetEnt |
| 5. | Thrones of Persia | 98.8% | Tom Horn Gaming |
The highest RTP slots return around 99% of the overall money played. These games are extremely rare, and when you go down to 98% or 97% RTP slots, you get a ton more options. It is worth noting that the RTP is a theoretical value. It does not mean that your RTP for a single gaming session is by any means guaranteed.
Thrones of Persia was also among the 98 RTP slots highlighted by our casino experts.
Online slots are packed with mechanics and features that shape how each slot plays and pays. While the reels and symbols are what you see on the surface, it's the underlying mechanics, like RTP, volatility, paylines, and bonus rounds that define the experience.
We explain the most important aspects of online slots below:
When you play online slots, you have access to different kinds of bonuses aimed at slot players. Online casinos have different ways of welcoming new players, rewarding active ones and promoting games by giving you free perks and extra funds for games.
Finding what slot bonus types are good for you can help you get more play time with the same amount of money. Knowing how to use bonuses can also help you turn them into withdrawable cash more easily.
Here are the common types of slot bonuses.
[text-box]
The slots welcome bonus is a booster for your first deposit. When you make a deposit as a new player, you get bonus money or bonus spins on slots on top of your regular deposit. The most common offer is to match your deposit and add a handful of spins on selected slots.
The bonus funds are great for trying out different games and seeing how the casino works. What you win from the sign up bonus slots can also be converted into withdrawable cash.
Free spins are some of the most coveted bonuses there are. These are spins you get simply by joining a casino. You don't need to deposit anything at all, so you are not risking your own money.
Because the no deposit free spins UK casinos have are so valuable, the number of spins is usually quite low. However, by following the terms, you can turn the spins into real money.
Wagering requirements are what makes some bonuses significantly better than others. They are a term that requires you to use the bonus money in the casino a certain amount of times before it is turned into real money. The higher it is, the likelier you lose the bonus before the requirement is fulfilled.
When you pick an online casino with low wagering requirements on bonuses, you can turn those bonus funds into cash faster. When you go all the way to no wagering slots, everything you win from them is immediately paid in cash.
Reload bonuses are deposit bonus offers you get when you are already a customer in a casino. These are deposit bonus offers for your second, third, or any subsequent deposits.
We have listed casino reload bonuses in the United Kingdom, which are suitable for those players who like to find a good casino and stay there. These sites can even have bonus calendars with repeating reload bonuses.
Cashback is a bonus that keeps on giving and is great as a long-term bonus. A cashback bonus will give you back a portion of your net losses. The most common one is 10% of your weekly losses, which is paid in wager-free cash.
Some UK casinos offer permanent cashback, and some have even higher percentages for loyal customers. An online casino offering cashback on losses is a good pick if you prefer minimising your losses over maximising your chances of winning.
Once you've got a slot site pinned, it's time to compare the slot bonus terms and conditions. These pay a heavy role in how much value the promotion can directly give you.
When you find a bonus offer, make sure you check the following terms:
Playing slots on your own is fun, but slot tournaments can make the games even more exciting. Now you can play the game and compete with other people at the same time. The best part is that you can win extra prizes at no cost to you.
The tournaments have different goals, but the idea is always the same. Play the slot and do better than other participants to win more.
You can find all the current slot tournament events on our dedicated tournament page. There, you can see which casinos are hosting tournaments right now and what kind of competitions they are running.
Slot tournaments work by you joining the event, playing the selected game or games, getting a leaderboard score by winning in the slot, and then seeing if you did well enough to win any of the prizes.
The goal of the tournament can vary, and knowing what to shoot for is vital. Here are some of the common tournament types you can encounter:
You can always check your score on the leaderboard and see how well you are doing. When the tournament timer goes to zero, the tournament is over, and the best players win.
The quality of slot games comes down to the slot providers behind them. Fortunately, UK slot sites have online slots from the best slot providers in the industry.
All slot providers offer something different, whether it's unique bonus features, signature game mechanics, or a consistent stream of new releases.
