How to Play Online Slots
Online slots come in a variety of styles, designs, and sizes, with appealing graphics, innovative features, captivating gameplay, rhythmic music, and occasional large payouts. However, the basic rules and structure of the game remain the same; players place their bets, click spin, and hope for a win.
Online slot machines consist of reels and rows, the number of which varies depending on the game variant. For example, traditional slots usually have 3 reels and 3 rows (3×3), while video slots can have more than 5 reels and at least 3 rows. The goal is to line up symbols across the reels on active paylines to win.
Here’s a simple step-by-step guide on how to play online slots:
- Register at one of our highly recommended online slot casinos;
- Make a deposit, obtain the bonus, and select your favorite online slot game;
- Make sure you are familiar with the game rules and the value of each symbol;
- Choose the number of paylines you want to play (some slots have fixed paylines, while others can be adjusted);
- Determine your bet amount (you can choose anything from the minimum to the maximum or simply press the max bet button);
- If desired, select the autoplay option, which can usually provide up to 100 automated spins or more;
- Press the Spin/Start button to start the game and hopefully, win.
Factors That Make The Best Slots Games
Online slots generally look great aesthetically, but certain elements determine how much of an amazing slots experience players can get. The major slot characteristics are:
- Payout percentage
- Paylines
- Volatility
- Bonus rounds
A higher payout percentage slot will be more profitable to players, just as numerous bonus rounds would take the entertainment level up a few notches.
Game manufacturers use these factors to develop online slots, so it is important to understand them before you begin playing them. We will explain each one in more detail below.
Payouts and RTP
Understanding the concept of Return to Player (RTP) is important when playing online slot games. This percentage is an estimate of the money a game will return to the player over a long period of time, based on an average calculation.
RTP essentially gives insight into the house advantage. For example, if a slot game has an RTP of 94.75%, it means that the house will theoretically keep £94.75 for every £100 bet. However, because slot games are based on chance, some players will win while others will lose. That’s just the nature of the game.
The RTP gives you a rough estimate of the average return you can expect. Ideally, you should choose a game with the highest RTP. For instance, NetEnt’s Mega Joker has an RTP of up to 99%, and Jackpot 6000 offers up to 98.8%, making them some of the top slot games in terms of RTP.
When you browse the games on the best online slot sites, you’ll find a payout table. This chart shows symbol values and paylines, explains features, and provides jackpot information. The payout tables also list the winnings in either cash or a multiplier format.
For example, seeing ‘100x’ means you could win 100 times your single line bet. This chart gives details about bonus rounds in online slots, including the smallest and largest prizes. You can use this information to estimate your potential payouts on new online slots.
Best Paying Slot Games UK by Provider
When searching for the top-earning slot games in the UK, it’s essential to consider the game developers. Focusing on developers renowned for high-yield slot games can simplify your search.
Pragmatic Play, NetEnt, Microgaming, and RedTiger are among the leading developers of high-paying slot games in the UK. Another strategy to find the best-paying slot games is to read reviews from other players and industry experts. They may provide useful advice on the most profitable games. Don’t forget to check the game’s RTP (return to player) percentage and choose the highest one available.
Service Provider | Slot Game | Return to Player |
---|---|---|
NetEnt | Mega Joker | 98.90% |
QuickSpin | Jokers Strike | 98.11% |
Microgaming | Hot Ink | 98.00% |
YggDrasil | Jokerizer | 98.00% |
BluePrint Gaming | Fortune of Sparta | 97.04% |
Red Tiger | Wild Spartans | 96.43% |
Best RTP Slots
High RTP (Return to Player) slots are essential as they potentially offer players the best chances to reduce their session costs. But, keep in mind that RTP is calculated over billions of spins. Therefore, even with high RTP slots, long losing streaks can still occur.
RTP% stands for Return To Player Percentage
The RTP% is the theoretical amount of the total bet that is returned to the player as winnings, based on a large number of tested spins.
RTP% shows the part of the total bet that a game returns to players over a large number of spins. For example, a high RTP, like 98% or more, means that the slot game is designed to return 98% of all bets. A slot with an RTP of 96% is naturally lower. But, the RTP can be much higher or lower than the advertised number in a typical session of several thousand spins.
One thing is for sure, the longer you play, the closer your results will align with the projected RTP%. Here are some of the highest RTP slots available at the best UK-licensed casinos:
- Goblin’s Cave (Playtech) – 99.32%
- Ugga Bugga (Playtech) – 99.07%
- Ooh Aah Dracula (Barcrest) – 99%
- Mega Joker (Netent) – 99%
- Jackpot 6000 (NetEnt) – 98.86%
- 1429 Uncharted Seas (Thunderkick) – 98.6%
- The Catfather (Pragmatic Play) – 98.10%
- Rainbow Riches Pick n Mix (Barcrest) – 98%
- Blood Suckers (Netent) – 98%
- Jokerizer (Yggdrasil) – 98%
How to Find a Slot RTP
Thankfully, RTP information for most slot games can be found on the provider’s or casino’s website. By looking in the slot’s help or information sections, players can discover the RTP for specific games. This information can help players make informed decisions, preferring slots with higher RTP over those with lower values.
Slots RNG (Random Number Generators) and How they Affect Games
A random number generator (RNG) is a device that determines the result each time you spin a web slot game. RNGs are used not only in online games, but also in physical slot machines in casinos and arcades. They’re also used to determine outcomes in online casino games, like those on blackjack sites.
The randomly generated number is processed by the game’s software, leading to a definitive outcome – a win or a loss.
All licensed operators serving UK players are under the supervision of the UK Gambling Commission (UKGC). The UKGC monitors the RNG technology used by online slot sites to ensure its fairness.
Slot Paylines and Paytables
Paylines are patterns (or lines) on the reels that award a win when you land matching symbol combinations. Lines can be fixed or variable, and variable paylines allow you to set the number of win lines per spin.
Knowing the number of paylines a game has is important because it determines your chances of landing a winning combination.
Imagine a 5-reel video slot with 20 paylines and another with 50 paylines. You will have more ways to win with the 50-line slot than with the former.
You can find the paylines displayed within the paytable, alongside the game symbols and how much each pays when you land a matching combination. Always visit the paytable before playing online slots to better understand the game’s rules.
Paylines
- Reel Payout Line Wins
- Total Payout Line Wins
- Wins through Cluster Pays™
When considering a slot machine, not only the number of reels matters, but also the design of the reel. It’s important to know whether winnings come from aligning symbols on neighboring reels, on consecutive reels regardless of position, or if it is a Cluster Pay Slot.
We’ll start with the traditional reel-to-reel slots requiring adjacent symbols, before moving on to the modern and more complex versions.
Reels-Based Paylines on Slots
In the time of classic pokies and one-armed bandits, slot games usually had just one winning line. But, the development of video slots and online slot games has significantly broadened this idea. Today, there are countless options, including the ‘Megaways’ mechanic licensed by Big Time Gaming, offering up to 117,649 various winning combinations.
Select Your Pay Lines
Choose from a wide range of options, from as little as 5 to Megaways slots of 117,000 and beyond. The most popular payline choices are 10, 25, and 50.
Although the number of pay lines may seem impressive, the addition of more reels, rows, and innovative board designs makes it possible to achieve thousands of pay lines.
Note that the number of pay lines doesn’t affect your chances of winning in a slot game. The odds are determined solely by the return to player percentage (RTP).
Extra pay lines simply enhance the slot game’s layout and fun factor – they don’t guarantee a higher potential win on a single spin. Thus, don’t play multi-payline slots aiming to win bigger or more frequently – it doesn’t work like that.
- Starburst, a NetEnt creation, features a 5×3 grid with 10 paylines
All Ways Paylines
Megaways, also known as all-ways paylines, is a recent innovation in online slot gaming. It’s a product and a mechanic that can be licensed, but the broader term for all games using these paylines is ‘All Ways’.
This means that symbols don’t need to be adjacent on the reels. As long as the same symbol is anywhere on each reel, it results in a winning line.
Potential for 117649 winning combinations with Megaways
Considering 6 rows and 7 possible symbol appearances for a ‘full-screen’, it gives 7x7x7x7x7x7 = 117649 possible winning combinations.
Having two or more identical symbols on a reel leads to extra winning line variations. For example, a 6-in-a-row winning symbol with the quantities 1-2-3-2-1, results in 12 winning combinations.
A simple way to understand this is by multiplying – 1x2x3x2x1=12.
So how do Megaways Slots make 117649 possible winning lines?
With the setup of up to 7 symbols on each of the 6 reels, the total possible winning combinations can reach a staggering 117,649. This figure is achieved by multiplying the possible symbol occurrences on each reel, so the calculation is 7x7x7x7x7x7 = 117,649.
Cluster Pays™ Slots
We’re exploring cluster pays™ slot mechanics, where a ‘cluster’ of symbols triggers base game wins.
These slot games typically feature boards with hundreds of squares instead of standard reels and rows. A 6 x 5 board, dropping 30 symbols, is common.
To win, you need a cluster of 5 or more identical symbols. The larger the cluster, the higher the multiplier applied to the stake, increasing the win amount.
This can work in one of two ways:
Adjacent Clusters
In neighboring clusters, victory is attained when a certain number of symbols are grouped adjacently. For instance, the Sugar Rush from Pragmatic Play game uses a 7×7 board. Here, a cluster of 5 adjacent symbols results in a win.
Clusters Anywhere
Clusters anywhere means that symbols can be placed randomly on the board to win, without being adjacent. For instance, in the Gate of Olympus game, a win is triggered by at least 8 identical symbols. The winning symbols then disappear and are replaced, potentially leading to more wins with multipliers.
The Sweet Bonanza slot game from Pragmatic Play is a popular example of this concept, due to its standard board setup.
Slot Machine Volatility
Simply put, volatility (also known as variance) describes the behaviour of a slot game. Online slots can have low, medium or high volatility. Low volatility slots will pay out small amounts frequently. The terms of maximum win is they happen less often with high volatility slots. And medium volatility cuts right through the middle.
With volatility, there is no better or worse kind. It all depends on what you expect from your gameplay – whether you’re looking to earn a couple of extra bucks with constant payouts or you’d rather hit it big on a lucky spin.
Bonus Rounds And In-Game Features
The latest online slots are all about the bonus features, commonly:
- Wild symbol – Wild symbols are a special game character that substitutes for regular symbols to complete a winning combination.
- Scatter symbol – a special game character that triggers the bonus game and often awards instant cash prizes.
- Multiplier – used to multiply the amount of a winning combination. It can be as high as 10x or more.
- Bonus game – the highlight of casino slots, where you can benefit more from wilds, scatters and multipliers. The riches bonus game is often a free spins round but can also be a pick-and-click game or some other special feature.
Special Symbols
Unique icons in online slot games can be a player’s best friend. They provide features that can greatly enhance your odds of winning, such as wilds, scatters, multipliers, and free spins. Wilds are special icons that help create winning combinations by replacing other symbols on the reels. Scatters trigger bonus games or free spins, depending on the number you land on the reels. Multipliers boost the total win of a spin, while free spins enable more wins without reducing your funds. Understanding the power of these unique icons can significantly improve your slot game experience.
Symbols for Free Spins
Free spins are an excellent way to unlock higher rewards in online slot games. To get these free spins, players need to watch for free spin symbols that appear randomly. These symbols come in different forms, often related to the game’s theme, and offer free opportunities to potentially win a payout. Most slot games also have special features like bonuses or mini-games, which provide opportunities to increase your winnings or trigger free spins. The characteristics of these features vary depending on the game.
Scatter Symbols
In slot games, scatter icons are valuable symbols that can offer various rewards to players. They can appear in many forms, and when several show up, they may trigger special features of the slot game. Depending on the game, these scatter icons can initiate bonus spins, multipliers, or mini-games like ‘choose-a-prize,’ where players can win credits. Even without the correct scatter icon combination to activate these bonuses, players can still benefit as scatter icons can often provide wins even when they don’t appear on active pay lines. Whether a beginner or an experienced player, understanding scatter icons can greatly improve your slot gaming experience.
Bonus
Online slot games offer various bonus icons and features to enhance your gaming experience. These unique symbols can trigger bonus features, providing extra spins or bonus cash. These can increase your chances of winning, offering features such as bonus mini-games, multipliers, rounds, and jackpots. So, while playing online slots, watch out for these bonus icons and features, as they can lead to larger wins than expected!
Wilds
Untamed elements are a common and powerful feature of online slot games, helping you secure big wins. These Wild symbols act as substitutes, allowing players to create winning combinations. There are several types of Wilds, including Sticky, Walking, Expanding, and Stacked Wild symbols. Sticky Wilds stay in place while the rest of the reels spin, and Walking Wilds move horizontally across the reels until they drop off either side of the screen. Expanding Wilds can stretch, usually vertically but potentially in any direction, to cover their respective reels and rows when they contribute to a win. Stacked Wilds fill an entire reel, turning into multiple Wild symbols stacked on top of each other, often combined with multipliers – this adds extra excitement to your gameplay!
Multipliers
Online slot games often include amplifier symbols. These features can increase players’ gains by a set amplifier value, ranging from 2x to 500x. The size of the amplifier symbol dictates the value.
Some amplifier symbols may require landing a specific number of symbols in one spin to qualify for an amplifier bonus. It’s crucial to fully understand the game’s layout and instructions before playing to increase the odds of getting amplifiers with each spin.
Types of Slots
The variety of online slot games is immense, with different shapes, sizes, styles, and types. If you’re a regular slot player, you might have your favorites, but exploring and understanding other types can be interesting.
Reel-Based Slot Games
Modern slot games are not limited to the reel format. Unlike old-school fruit machines, which typically had three reels and one win line, plus two more visible lines, today’s versions offer a wide variety.
While 3-reel slots are still prevalent, you can also find ones with 4, 5, 6, 7, and sometimes even more reels.
3 Reels Slots
Playing a 3-reel slot game allows you to match three identical symbols on one line. These games typically have a 3×3 grid, with three lines and three reels. This layout usually offers five chances to win – the three horizontal lines and two diagonals from left to right.
Usually, you need three identical symbols to win, but there can be exceptions. For instance, for high-value symbols, sometimes only two are needed on a winning line.
4 Reels
- Big Time Gaming’s “Donuts” game is a classic example of a simple 4-reel slot.
A 4 Reel slot includes an extra reel, providing more winning symbols and potentially higher multipliers for a four-in-a-row win.
These 4 Reel slots are sometimes called 4×3, representing 4 Reels and 3 Rows.
The addition of the fourth reel increases the possible pay lines. Depending on the slot’s setup, the previous five win lines could grow to 10, 15, or even 20, giving players more opportunities to secure four reel wins.
5 reels
- Big Bass Bonanza is a slot game with 5 spinning wheels
Considering the 3-row structure, 5-reel slots are often represented as 5 x 3, indicating five reels and three rows.
The inclusion of an extra reel increases the possibility for more winning lines, typically not exceeding 50 unless an ‘all-ways’ or ‘megaways’ format is used.
The result is usually between 10 – 50 pay lines, with 25 being the most frequent. However, using all-ways winning where symbols are not necessarily directly connected, it’s possible to achieve 243, 1024, and even more depending on the number of rows in the game. Still, some slots might have 243, 1024, or even 16807 pay lines.
6 Reels or More
- Slots with more than 6 reels are available, including the 6-reel buffalo blitz by PlayTech
A variety of 6 Reel slot games are available, offering 6 consecutive winning opportunities with potentially high returns. However, this usually means giving up many small wins for three consecutive matches and often requires at least four free spins or scatter awards to trigger bonus features.
This also increases the number of possible pay lines, with six reels being the most commonly used layout for Megaways slots.
Slot Game Themes
The variety of slot game themes is endless, encompassing different individual motifs, combinations, and unique themes.

Jackpot Slots
Several of the top UK online slots are jackpot slots, e.g. Megabucks. These offer the chance to win huge amounts of money on a lucky spin. These prizes are fixed, so you already know how much you can win if you hit the pot.
You will have to trigger a jackpot by landing a specific combination of symbols or playing a bonus game. It isn’t hard to find these games as many slots feature one or more huge jackpot prizes, including slots like:
- Wacky races
- Mustang Gold
- Star Joker
- Wolf Gold
- Crazy Time
Progressive Jackpots
While regular jackpots are fixed, progressives like Playtech’s Green Lantern accumulate by taking a small portion of every amount wagered on a spin. So the prize continues growing as players keep on playing.
That’s why progressives are called millionaire-makers. These amounts aren’t just huge but life-changing. And the best part is that you don’t have to make the max bet. You can win even with minimum deposits and the smallest stakes.
Microgaming’s Mega Moolah remains the top progressive jackpot slot with a record €18,915,872.81 payout. Other standout progressive slots include:
- Mega Fortune
- Hall of gods
- Major Millions
- Arabian Nights
- Age of the Gods
Fruit Machines
Fruit machines are some of the most common slots in the UK. Their name comes from the fact that most symbols on the reels are fruit icons, alongside bells, 7s, and bar symbols.

These features help increase your chances to win at slot, and it’s worth noting that fruit machines often come with multiple jackpot prizes.

Casino Bonuses and Free Spins on Slots
These days, every online casino site offers welcome bonus offers to new players to make them join the site. You often get one bonus offer per player, but some operators will extend these rewards to the 2nd deposit, 3rd deposit and even 4th deposit. Not to mention continuous ongoing promotions for players who keep coming back.
Free spins are one such grand ivy casino bonus specific to slots. They allow you to spin the base game reels several times, free of charge. The best online slots UK casinos will offer as many as 200 or more free spins on your first deposit. Some sites will also provide wager free casino offers in the form of no deposit bonuses. The slots casino may offer bonus spins on selected games, or you may be given a free hand to play your preferred titles.
Although this slots bonus is a major player magnet, just like any other casino promos, t & c apply.
Bonus wagering requirements are the most prominent conditions because you have to fulfil them before receiving a payout on your winnings. Consider you receive a bonus of £100 and are subject to 35x wagering the total bonus amount. You would have to bet £3500 to withdraw your winnings. Game weighting applies in cases where you end up with wagering requirements from a welcome bonus.
The wagering requirement can be between 20x and 50x of your free spins winnings, but a 30x wagering bonus or lower is recommended to play responsibly.
You also get the bonus valid for a specific time frame (usually 7 days, otherwise, any unused bonus shall be removed). The bonus funds contribute towards wagering, so the latter is valid until the bonus funds expire.
In addition, you will find other restrictions like a max bonus bet to comply with. At montycasinos.com, we advise players to read the bonus T&C before accepting any welcome offer.
Fairness of Slot Machine Outcomes
Casino online slots like Buffalo Blitz run on a random number generator (RNG) software, which determines game outcomes. The RNG ensures that every spin’s result completely depends on chance.
To verify that bovada casino RNGs work as they are supposed to without any external manipulation, they have to be tested by reliable audit services like eCOGRA. Only the top online licensed sites have a seal of approval from eCOGRA. These top slot casinos are regulated by the UK Gambling Commission and are trustworthy and reliable, so you can also expect fair play from their games. Operators like Paddy Power and Jackpot Village have multiple licenses from the UKGC and the MGA (Malta Gaming Authority).
