Types of Free Slots to Play
Demo slots come in all shapes and sizes. With various types of slots available, below are the most common types of slot games you’ll encounter:
Reel Style of Slots
Slots do not come solely in reel format these days. In days gone by when fruit machines would traditionally be a single win line with three reels, with a further two lines above and below in view, the permutations today are phenomenal.
You can indeed still find 3 reel slots, as well as 4, 5, 6, 7 and even more in some cases.
3 Reels: 3 reel slots are typically found in land-based casinos. Also known as classic slots, they have 3 reels and 1 singular payline. Winning combinations are created when you land 3 matching symbols across the middle of the screen.
5 Reels: More commonly found, the majority of slot games have 5 reels. The number of paylines varies but the standard range is between 10 and 50. To land a winning combination, you will typically need to see 3 or more matching symbols across any of the paylines. The more paylines winning combinations land on, the bigger the payout.
Big Bass Bonanza is an example of a 5 reel slot
All Ways: These slot games typically have 5 reels and allow winning combinations from matching symbols in any direction and anywhere on the reels. 243 or 1,024 ways to win slots are classed as ‘All Ways’ slots with the concept coined by Microgaming.
6+ Reels: Slot providers have increased the number of reels (as well as paylines or ways to win). With Light & Wonder (formerly Scientific Games/WMS) releasing Raging Rhino, it was the first game to have 6 reels and 4,06 ways to win. Providers such as ReelPlay added to this with Infinity Reels.
6 reel slot and even more are available, this is 6 reel buffalo blitz from PlayTech
Megaways: Created by Big Time Gaming, Megaways slots has become a phenomenon in the online gaming world. Normally played with 6 reels, the number of ways to win randomly changes on each spin. The more symbols per reel, the more Megaways. The typical number of Megaways is 117,649.
Cluster Pays: With no traditional reels or paylines, Cluster Pays slots are played on a grid with winning combinations formed when a certain number of matching symbols appear adjacent, either horizontally or vertically. The more matching symbols appearing in a cluster, the bigger the payout.
Scatter Pays: Similar to Cluster Pays games, Scatter Pays slots have no reels or paylines. Wins are awarded when a certain number of matching symbols land anywhere in view.
- Progressive Jackpots: Commonly known as jackpot slots, they are regular slot games which give you the chance to land a progressive jackpot. A portion of all bets goes into a progressive jackpot pot which is then randomly won by a lucky player. Increasingly popular, the largest ever progressive jackpot won was a cool €38.4 million on Microgaming’s Wheel of Wishes in December 2023.
Free Demo Slots on Mobile Devices
The desire for mobile demo slots has increased dramatically with most players opting to play free slot demo games on their smartphone devices. Created using HTML5 technology, all slots can be played on laptop, PC, MAC, tablet and mobile devices with no download needed.
Compatible with iOS or Android mobile devices, free demo play slots use a special Portrait Mode to maximise your full smartphone’s screen.
With most games being ‘mobile-first’, you’ll benefit from an enhanced playing experience when playing using a mobile device.
The good news is that your chosen device will be detected automatically with the appropriate dimensions applied automatically.

Best Paying Slot Games UK by Provider
If you are searching for the best payout slots in the UK, one of the most valuable strategies is to look at the slot providers themselves. Focusing on providers with a track record of developing high-payout slot games will narrow your search.
Some of the top slot providers of best payout slots in the UK include Pragmatic Play, NetEnt, Microgaming, and RedTiger. Another way to find the best payout slots is to read Slot game reviews from other players and industry experts, who can provide valuable insights into the best games available. Remember to also look at the game's RTP (return to player) rate and pick the greatest you can find.
| Provider | Slot | RTP |
|---|---|---|
| Playtech | Ugga Bugga | 99.07% |
| Relax Gaming | Book of 99 | 99% |
| Thunderkick | 1429 Uncharted Seas | 98.6% |

| NetEnt | Blood Suckers | 98% |
| Relax Gaming | Money Cart | 98% |

Best RTP Slots
High RTP (Return to Player) slots are essential because they offer players theoretically the highest chances of losing a smaller amount of their session spend. RTP is set over billions of spins, though, so bear this in mind, and long losing runs, even on high RTP slots, are not unusual.
RTP% = Return To Player percentage
RTP is the percentage of the total wager amount the game pays back to players over a specific and unimaginably long period of spins. A high RTP of 98% or more means that the slot game payout is programmed to return 98% of all stakes over that time. A 96% RTP slot sits lower, as you would imagine - But no matter the RTP, in an ordinary session of even a few thousand spins, RTPs can be much higher and, more frequently, much lower than the advertised theoretical figure.
One thing you can be sure of is that the longer you play, the closer you will get to the advertised RTP number.
What is Return to Player Percentage in Online Slots?
Return to player is the percentage of wagered money is return in winnings over time when playing slots on a casino app.
Long losing runs and good winning runs will over course be over a shorter period and will return lower and higher percentages will be useful in the short term, but once evened out over time, the RTP is an accurate view of how the slot is set up.
Quite simply, the higher the RTP, the higher the percentage of money wagered is returned in winning spins and bonuses.
98.9% RTP Example
How long is “time” in this case?
Well, there is actually no defined ‘time’ as it were, it certainly can’t be narrowed down to an exact number of spins, and of course, if it were a very tight timeline it would make it impossible to win on slots in the short term, which, of course, you certainly can.
The advice is simple, if you get ahead, regardless of the growth of your original bank, eventually you will lose in the long term, so stopping while you are ahead has never been more apt.
RTP Levels are to ensure the Casino Wins.
You will already have figured out that if you flip the percentage RTP, you will have the house edge.
So in this example where we are looking at an RTP of 98.9%, the house edge on this game is 1.1% which is generous in comparison to standard single zero roulette house edge of 2.70%
If you are playing any slot with an RTP of at least 97.3%, you are getting better odds than if you play Roulette.
When choosing a slot and best payout percentage, try to keep your choice to the recommended RTP level as outlined above or consider this handy guide:
| RTP Level | When to Play |
|---|---|
| 97% | Most Often |
| 95-97% | Less Often |
| 93-95% | Rarely |
| Under 93% | Try to Avoid |
Paylines
- Reel Based Paylines Wins
- All Ways Payline Wins
- Cluster Pays™ Wins
In addition to the number of reels that can be found on a slot, there is also the consideration of the reel style and whether wins are achieved by lining up on adjacent reels, anywhere on consecutive reels, or falling into the category of Cluster Pay Slots
Let's start with traditional style reel-to-reel slots requiring adjacent symbols before moving into the more modern and complicated version
Reels-Based Paylines on Slots
Once upon a time, there would be only one win line on a slot game in the days of the old pokies and one-armed bandits. These days with the evolution of video slots and online slot games, the permutations are almost endless, with many slots, including the Big Time gaming licensed 'Megaways' mechanic, offering anything up to 117,649 ways to win.
Choose your Pay Lines
This number of pay lines seems fantastic but with increased reels and rows and imaginative board creations, thousands of pay lines are achievable.
It should be noted that the number of pay lines make no difference to the likelihood of winning on a slot game. The chances of winning are determined by the return to player percentage (RTP) only.
Additional pay lines are only for the design and experience on the slot game and the entertainment value - it doesn't even determine a greater possible win amount on a single spin. So don't play multi-payline slots in the aim to win bigger or more frequently - it doesn't work that way.
Starburst from NetEnt has 10 paylines on a 5x3 board
All Ways Paylines
Often referred to as Megaways, all-ways payline slots are a newer form of online slot play. Megaways slots is a licensable product, mechanic and name - The correct term to include all games using these paylines is All Ways
Quite simply, this means that symbols do not need to appear adjacently on the reels; rather, as long as the same symbol appears anywhere on each of the reels, you will have a winning line.
Up to 117649 possible winning lines on Megaways
Should you have 2 or more same symbols on a reel, this equates to more winning line permutations; so for instance, if you had a 6-in-a-row win of a symbol, with the following quantities - 1-2-3-2-1, this would represent 12 winning lines
The easy way to understand this is to create a simple multiplication - 1x2x3x2x1=12
Best Megaways Slots Guide 2025
So how do Megaways Slots make 117649 possible winning lines?
With up to 7 symbols per reel and 6 reels on a game, the possible number of winning lines is an incredible 117649 and this is arrived at by multiplying the possible symbol appearances by each of the 6 reels. Thus, the permutation calculation is 7x7x7x7x7x7 = 117649
Cluster Pays™ Slots
Now we have covered traditional reel and row win lines, and then the all-ways winning line possibilities, we move into the newer slot mechanics of 'cluster pays™'. As the name suggests, a 'cluster' of symbols are required to trigger base game wins here.
The boards for these types of slots are often different in that rather than reels and rows, a board made up of sometimes hundreds of squares is played. Most often we will find a 6 x 5 board in this form of slot game, providing a drop of 30 symbols.
Within the 30 symbols, we could be looking for a cluster of 5 or more matching symbols for a win. The larger the cluster of symbols, the higher the stake multiplier applied to the win.
This can work in one of two ways
Adjacent Clusters
With adjacent clusters, a minimum number of symbols that are adjacently joined will gain the win. Here we use Sugar Rush from Pragmatic Play, which features a 7x7 playing board where a cluster of 5 adjacent symbols will trigger a win.
In the example image below, we can see the green stars and the Pink lollipop tops are both clustered in groups of more than 5, which would both pay wins
Anywhere Clusters
With anywhere clusters, we are looking at a minimum number of symbols falling anywhere on the board. They do not have to touch. In Gate of Olympus, a minimum of 8 matching symbols triggers a winning spin where the symbols disappear and are replaced for potential further wins with multipliers and more.
Let's take the Sweet Bonanza slot game from Pragmatic Play as an example here, being the most common board configuration
Volatility
The volatility of slot games is a measure of the winning style and frequency of a game, and can be a consideration for many players when selecting which slot they like to play.
Slot Volatility Explained: How Risk Levels Impact Your Slot Play
Understanding volatility is also crucial for your slot gaming enjoyment. Some slots even allow you to choose the volatility level for your game.
- High Volatility = Fewer but bigger wins
- Medium Volatility = Average Wins, medium value
- Low Volatility = More frequent wins but at a lower level
Regardless of volatility, the RTP will almost always be the same.
High Volatility Slots
High volatility slots can be high risk and high reward. While high volatility slots will often pay fewer wins than lower volatility, the wins you receive are usually of a bigger value. This means that high volatility slots can lead to quick big wins; however, it is important to remember that high volatility also implies long and expensive losing streaks. If you are looking for an exciting gambling experience to win high stakes, high-volatility slots may be the right choice. Just remember to use caution and gamble responsibly.
Example of High Volatility Slots
- Book of Dead (Play'n Go)
- Big Bass Bonanza (Pragmatic Play)
Medium Volatility Slots
Medium volatility slots are a great option for players wanting to experience some thrills without risking too much. While these slots may not offer huge payouts like their high volatility counterparts, they do provide more consistent wins and average prizes - perfect mediums between large rewards and low risk. medium volatility slots make it easier to manage playing funds due to the absence of long-lasting losing streaks. On the other hand, players can still make good wins occasionally, providing them with enough motivation to keep playing. If you want to play slots on a budget and with less risk, medium volatility slots could be just the thing for you!
Low Volatility Slots
Low volatility slots are ideal for players who are looking to experience frequent winning spins and small but steady wins. By the same token, they feature the same chance of losing, so are no more sure than high volatility, but it may take longer to get further into the red. Unlike high-volatility slots that feature big wins, low-volatility slots have smaller payouts more frequently, with spin values typically ranging from 0.1x up to 1x. While low-volatility slots don't typically give out huge jackpots (as is the case with high-volatility slots), they also offer far fewer 'dead' spins between wins - meaning more continuous fun and bonus features. If you're an occasional casino player, low-volatility slots offer a great way to keep up your enjoyment.
Extreme Volatility Slots
Extreme volatility slots are a fast-growing area of slot play and those considering playing them should proceed very cautiously. It’s important to understand that big losses can occur swiftly and dramatically; it would not be unusual to spin thirty or forty times without luck and lose your balance in the blink of an eye. Extreme volatility slots often tout ‘unlimited win potential’, as well as incredible maximum wins like 50,000x, but it’s worth recalling that these figures are theoretical - actual achievements of such wins being extremely uncommon in real-world play. Ultimately, be aware that playing extreme volatility slots is an extreme action itself, and risks should be considered before taking the plunge.
Online Slot Features
One of the biggest attractions in selecting a demo slot to try is the features included in the game, on the reels and the symbols. Personally, this is the deciding factor when I choose the new slots I want to try.
Base Game Wins
When playing online slot games, base game wins refer to a win on each spin without triggering a feature or bonus round. Unfortunately, base game wins are usually low and can be as little as 0.1x your stake, meaning the spin is actually still a losing spin in terms of your balance. E.G You may be spinning at £1 a spin, but a 0.1x win would return just £0.10 meaning a 90p loss on the individual spin. It's possible for base game wins to land some higher value wins occasionally but these are generally far and few between, meaning that players must rely on bonuses like free spins or feature rounds in order to secure larger wins. This is why it's important to read through the game's rules and information before playing, so you know what you can expect from base game wins.
Low-Value Symbols
Low-value symbols are those items in online slot games that typically don't pay out great odds. These symbols may be represented by low-number card symbols, like 9, 10, J, Q, K, and A, or can take the form of low-value items like more basic graphics or less colourful.
Low-value symbols tend to appear frequently on the reels, giving players many opportunities to accumulate low-paying combinations. Although low values symbols usually don't pay out great amounts, they can still help build a half-decent win if full-screen or full-row wins are achieved. To understand low-value symbols, players should keep an eye on paytables that display the range of prizes associated with combinations of low-value symbols.
Low value symbols on Fishin Frenzy are the card based numbers and letters, with imagery for the premium symbols
High-Value Symbols
High-value symbols provide the potential for larger base game wins and free spins wins when playing online slot games. Symbols vary depending on the game and can range from high-definition graphics to enhanced versions of low-value symbols. Often base game wins of combinations of these premium symbols will pay a minimum of 1x your spin-stake when landing in the required combinations.
Special Symbols
Special symbols in online slot games can be a gamer's best friend. These symbols provide features that can help increase your chances of success - from wilds and scatters to multipliers and free spins. Wilds are special symbols that help to create winning combinations by replacing other symbols on the reels. Scatters, meanwhile, will trigger bonus games or free spins depending on how many you land on the reels. Multipliers will multiply the total win of a spin, while free spins give the chance to get extra wins without using up any more of your bankroll. Special symbols truly make all the difference when it comes to enjoying a slot game, and understanding their powers could help you gain real success.
Free Spins Symbols
Free spins are a great way to trigger chances of winning larger prizes than base game wins when playing online slot games. To be eligible for free spins, players must look out for free spin symbols which appear randomly during gameplay.
