How do Online Slots Work?
The first and most important thing that you should know is the technology that powers slots online. Game providers develop these games and optimize them for use at UK online casinos. Each slot comes with its own set of reels and rows.
In most cases, there are one of three ways to form winning combinations here. The first one is left to right, the second one is right to left and the third is both ways. Every game has a certain number of paylines. They show you the possible winning ways.
You gain wins with the regular symbols in the slot. In many cases, UK online slots feature a Wild symbol. It substitutes regular symbols and can help you form winning combinations. The payouts in the game depend on the following things:
- The size of your bet
- Type of regular symbol
- Number of identical symbols that form a win
- RTP and volatility rates
- Maximum jackpot exposure
Regular symbols in online slots are usually divided into two categories – low-paying and high-paying. The higher the rank of the symbol is, the higher the payouts are.
Before you spin the reels, you will have to set your bet. Each game has a minimum and maximum limit. Additionally, slot games have extra mechanics that are vital to know. These are the RTP rate, volatility, RNGs, and jackpots.
RTP and Volatility
Return to Player (RTP) indicates the returns that you can have over a longer period. The higher the percentage is, the better. The average RTP rate of UK slots is 96%. If you access an online slot that has an RTP of 96%, that means that you can expect £96 for every £100 that you wager over time.
As for the volatility rate, it indicates how often the jackpot drops and how rewarding it is. The higher the volatility rate is, the more rewarding the jackpot is. However, you will likely not trigger it too often.
There are three main volatility levels – low, medium, and high. Medium volatile slots are the most popular in the UK as they represent the best of both worlds. Their jackpots have decent exposure and drop often enough.
Speaking of the jackpot, this is the ultimate reward that you can receive when playing online slots. There are two types – fixed and progressive. A fixed jackpot means that its maximum exposure has a limit. Even if you cross it, the game will give you its max payout.
On the other hand, progressive jackpots do not have a maximum limit. Every time a UK player wagers on a game of this type, a portion of the bet goes to the jackpot. In many cases, the rewards in progressive slots go over £1 million.
Random Number Generators
One of the most common issues that players have with casino games is fraud and rigging outcomes. Game providers and UK casino sites want to provide clients with maximum security and fair play. Additionally, ensuring a safe gaming environment is a must, according to the laws in the country.
That is the reason why slots use Random Number Generators (RNGs). An RNG is an AI tool that creates random outcomes for every round. As soon as you press the spin button, the RNG will create an outcome. Hence, your chances of winning are the same as every other UK player at the casino.
In recent times, the concept of provably fair gaming is also gaining popularity. It is present at UK crypto casinos. Not only does it create random outcomes for every betting round in online slots, but this concept also allows you to check whether the round was truly random.
Advantages of Playing Online Slots
Online slots in the UK boast a plethora of advantages. These pros allow players to have the most entertaining gaming experience. Of course, bonuscasinossites is there to share all the details related to these games, which is why we are more than happy to share these advantages.
One of the biggest advantages of online casinos UK is the fact that they are available 24/7. You can access them at any time and place, from any device. That means that you can play online slots from your smartphone or tablet if you feel like it.
There’s just one thing that you must make sure of and that’s a stable connection to the Internet. Of course, if you want to play for real money, you will also have to register at the UK casino.
Next up, online slots are extremely diverse. They come with different reel sets, themes, bonus features, payouts, volatility levels, types of jackpots, etc. You will find something that meets your preferences.
To add up, you can also try out new types of slots. Thanks to that, you will never have a dull gaming experience.
While talking about the jackpots in slot games, we stated that their exposures can often go over £1 million. Fixed jackpot slots can also have decent jackpots. Some of them have a maximum cap of over 50,000x your stake.
Each licensed online casino that features online slots is as secure as you can imagine. These platforms hold a license from the UK Gambling Commission and use the latest SSL encryption security system. Furthermore, they allow players to register under aliases.
Each of these measures indicates that your sensitive data is always kept out of harm’s way.
Finally, we have the fact that online slots by the best game providers use Random Number Generators. They give all players equal chances of winning and make game rigging impossible. So, apart from enjoying maximum security, you will also play in a fair environment.
Online Slots Bonus Features
Slot games pack quite a lot of bonus features. They make the gameplay all the more exciting and unlock the path to rewards. Up until a while ago, the only in-game bonuses that you could come across were free spins and Wild symbols.
However, as the industry kept evolving, so did the slots. Nowadays, suppliers make sure to add tons of features to these titles.
The Megaways payline mechanic is one of the biggest and most popular inventions in recent history. Big Time Gaming created it. Slots that have this mechanic usually have an extra horizontal reel on top of the main grid.
With this feature, each spin has a different amount of paylines. The upper limit goes as high as 117,649.
Cluster Pays is another payline mechanic that was developed by one of iGaming’s biggest giants – NetEnt. It reinvents the way to forming winning combinations. Instead of winning symbols having to land left to right or right to left, wins here are formed in clusters.
In other words, matching symbols need to touch horizontally and/or horizontally. In most cases, if you want to trigger a win, you must activate clusters of at least 4 or 5 matching regular symbols. Then, winning symbols disappear from the grid and the ones above them drop down.
While speaking about paylines, it is worth noting the Infinity Reels mode by ReelPlay. When you’re playing slots that have this system, each time you form a win, an extra reel shows up on the grid. In doing so, the number of paylines also increases.
Infinity Reels slots will provide you with a certain cash reward if you add at least 12 extra reels on the grid.
There’s no denying the fact that free spins are the most popular and most loved bonus feature. Usually, if you want to trigger them, you must land at least 3 Scatters on the reels. The number of free spins depends on the number of Scatters that you land.
Some games might allow you to re-trigger this mode an infinite amount of times. Others have caps on the maximum number of spins that you can receive. On rare occasions, you might not even have the chance to re-trigger free spins.
Many novice players confuse respins with free spins. They think that they are the same thing. On the contrary, a respin is a separate bonus mode. Triggering it depends on the rules of the slot. Some require you to land a special symbol. Others will give you a respin if you land 2 Scatters.
Next up, bonus rounds are interesting modes as they feature various prizes. During bonus rounds, you might end up with one of the following:
- Cash rewards
- Bonus spins
- Jackpot rewards
One of the most common types of bonus rounds is the bonus wheel. Once you activate it, you will have to spin it. The reward that you receive is adequate for the field where the wheel will stop.
The one feature that you can come across more often than free spins is the Wild symbol. Apart from forming wins on its own, it can substitute regular symbols as well. That way, it helps you trigger regular wins while playing UK slots.
Expanding, Split, Jumping, Nudge, and Mystery Symbols
Slots in the UK are as diverse as you can imagine. Hence, the Wild and Scatter symbols are not the only special symbols that you will come across. Additional specials include:
- Expanding symbols
- Split symbols
- Jumping symbols
- Nudging symbols
- Mystery symbols
All symbols in slots have a 1×1 layout. When you come across an expanding symbol, you will notice that its layout is 2×2. Often, it can be as big as 3×3 or 4×4. Split symbols are the opposite. A 1×1 symbol may split into 2-4 smaller symbols.
Jumping symbols transfer from one position to another and thus, give you extra chances of winning. Nudging symbols are similar to jumping symbols. The difference is that instead of moving to a random position, nudging symbols move to a spot where they can be a part of a win.
Finally, mystery symbols reveal their value when the reels stop spinning. In many cases, they can be a missing part of the puzzle when forming a win.
While talking about the mechanics that power UK online slots, we noticed that there are two types of jackpots – standard and progressive. Progressive jackpots often have several levels: Mini, Minor, Major, and Mega.
Each of these jackpots has a minimum and maximum limit. The Mega jackpot is the only exception as this reward does not have a maximum limit.
When you trigger the locked reels mode, one random reel on the grid freezes and its symbols stay there for the duration of the next spin or the next couple of spins. Depending on the rules of the UK slot online, you may even have the chance to lock multiple reels.
Just as the name itself suggests, multipliers increase your potential win by multiplying it. They come in various shapes and sizes. You can win them in the base game, during free spins, or when you land a Wild symbol. Sometimes, you may even come across a slot that has multiplier symbols.
Slots that have the Cluster Pays system usually utilize tumbling reels. This means that the symbols that trigger a win disappear from the grid. Then, the ones above them drop down. This process is called tumbling reels.
Thanks to it, you can form several consecutive wins. Multipliers might also apply and increase with each tumbling win.
Each online slot in the UK has a main bonus feature. In most cases, it’s free spins. If for some reason, you cannot trigger the main feature, you can purchase it with Bonus Buy. The cost of it varies, depending on the slot. Often, when you use Bonus Buy, the RTP of the slot also increases.
The final feature that you can come across at UK online slots is Gamble. This allows you to double your winnings or lose it all. When you trigger a win, the slot will give you a chance to gamble the winnings for a higher reward. Keep in mind that if you lose, you will not receive the amount that you won in the first place.
Most Popular Online Slots Providers in the UK
UK online casinos partner with dozens of providers. Each brand is known for its unique features. Some of them can stand out from the competition as they provide players with the best entertainment. With that being said, let’s take a look at some of the most influential ones in this country.
Coming in at number 1, we have one of the biggest giants in the online gambling industry – NetEnt. Some of the slots that NetEnt created over the years include Starburst, Gonzo’s Quest, Twin Spin, Aloha! Cluster Pays, Dead or Alive, Divine Fortune, and Narcos.
UK players are extremely fond of each of these games. They are packed with bonus features and have unique gameplay. These two features create the perfect recipe for a good gaming experience.
Yggdrasil is known for creating slot games that have above-average RTP and ground-breaking graphics. If you access and play slots such as Orient Express, Valley of the Gods, Vikings go Berzerk, Spina Colada, Holmes and the Stolen Stones, Jokerizer, or Beauty & the Beast, you will see what this supplier is all about.
There are several reasons why Pragmatic Play is a common pick for British players. Not only does it have quality games in its portfolio, but its partner casinos often feature the Drops&Wins promotion. As for its most notable titles, some of them include:
- Chilli Heat
- Wild West Gold
- John Hunter & Tomb of the Scarab Queen
- Mustang Gold
- The Dog House
- Sweet Bonanza
- Gates of Olympus
- Fruit Party
One major advantage that Play’n GO has is the fact that its slots are always eligible for bonuses and promotions at UK casinos. You can use these promos to maximize your winnings at these sites. To make things even better, all Play’n GO games offer decent payouts and have numerous features.
Moon Princess, Reactoonz, Book of Dead, Fire Joker, Honey Rush, Viking Runecraft, Wild Blood, and Mermaid’s Diamond are just a few of its most notable releases.
The fifth most popular online slot provider in the UK is Quickspin. This is another brand that creates games with breathtaking graphics and numerous bonuses. Pirates Charm, Big Bad Wolf, Sakura Fortune, Hidden Valley, The Wild Chase, and Mighty Arthur are just a fraction of the titles by Quickspin that you can come across at UK casinos.
Online Slots vs Land-Based Slots
Land-based gambling in the UK is almost as popular as online gambling. According to the Gambling Act 2005, these establishments are more than welcome to offer their services to residents who are of legal age. Of course, they need to have the proper accreditation.
When thinking of playing slot games, many UK players are debating whether they should do it online or at brick-and-mortar establishments. Below, we’ve compared the two options, so let’s see which one comes out on top.
✅ Massive diversity at UK casinos
✅ Numerous available cashout methods
✅ UK casinos are extremely secure and efficient
✅ You can use various bonuses and promotions
❌ Do not boost social skills
❌ Easy accessibility can lead to gambling harm
✅ Boost social skills
✅ Better option for responsible gambling
❌ Not as diverse as online slots
❌ You can withdraw winnings only via cash or cards
❌A fraction of available bonuses for players
❌ Often situated at distant properties
As you can see, both types of slots have a few pros and cons. Let’s start with land-based slots. Their biggest advantage is the social factor. You can make friends with other players at the respective establishment. You also can gamble more responsibly as you have better bankroll management.
However, they face quite a lot of disadvantages as well. You don’t have a lot of cashout methods at your disposal, they are not too diverse, and land-based properties do not offer a lot of bonuses.
According to the laws in the UK, land-based casinos must be a part of a multi-purpose establishment, such as a resort. That means that you may have travel far to reach them.
On the other hand, online slots boast tons of advantages. They are as diverse as you can imagine, you can cash out via numerous methods and online casinos are as secure as you can imagine. Since you are playing alone, they do not boost your social skills, though.
Additionally, you can access online casinos at any time and place. Some might argue that the easy accessibility may lead to a risk of gambling harm. This is true, but only to an extent. UK casinos must partner with RG organizations and offer self-exclusion programs to players. Hence, they have a license obligation to keep track of the spending power of the players and suspend them if they spend more than what they can afford.
