You may even pick up a jackpot or two on your travels.

While you may think going to a site with the most appealing deals and bonus codes is the best course of action to take, there are plenty of factors and features you’re going to need to bear in mind.

There are thousands of different games out there in October 2021 – how do you know which sites have the best online slots features?

Best Online Slot Sites

From our research, this is a list of the best slot sites:

Why Play Slots Online?

You can play slots online and win real money just like you would in a real casino. Still, there are a few advantages to playing at an online casino, such as:

• Better sign up offers
• Higher payouts
• Mobile slot availability

There is a vast selection of slots to choose from, with new online casinos being launched regularly. But how can you know which sites have the best bonuses, payouts, mobile experience, and game variety? Leave this to us!

How We Select The Best Online Slots Sites

In order to determine the best online slot sites, we use the following criteria when carrying out our extensive research in the slot site market.

Payouts

Payouts refer to how well the casino’s games payout and how quickly you can collect your money once you’ve requested a withdrawal.

We select slot sites with the highest RTP percentages, giving you more bang for your buck overall.

It is true that some of the biggest wins can come from the lower RTP games. However, these slot games are generally more volatile, meaning you will often go a lot longer without winning. If you are a high roller and want to speculate to accumulate, these could be the best slot sites for you.

All this information is covered in our latest slot game reviews.

Variety of Games

Variety of the spice of life! And this definitely applies to the best online slot sites.

Nobody enjoys playing the same games over and over again. Therefore, we award sites more points in our rankings if it has a large variety of slot games to play.

Mobile Compatibility

We give slot sites with good mobile compatibility the thumbs up when carrying out our stringent vetting process.

With more and more people now opting to play slot games on their mobile or tablet, we feel this is an important factor to consider.

Bonus Offers

With most decent slot sites offering some form of a welcome bonus, we try, test and handpick the best bonuses available and factor these into our selections.

The best slot sites have great welcome bonuses as well as rewards for existing customers. It is all well and good looking for the best welcome offers but we are also interested in loyalty for existing players.

Tournament Availability

Without question, slot tournaments are one of the most popular attractions that an online casino can provide.

Online slot players focus on accumulating points rather than gaining cash which can be a nice change from traditional slot gameplay.

Customer Service

We value good customer support extremely highly when listing the best slot sites.

It is always good to know that any problems will be met head-on and resolved quickly, especially if this involves payment.

Licensing and Regulation

Rest assured that our recommended slots sites are always secure and regulated by recognised bodies such as the UKGC and the MGA.

Furthermore, all of the mentioned slot casinos have SSL security certifications and are reviewed regularly to ensure that your game is fair and your data is held securely.

Online Slots Bonuses and Free Spins

In order to attract new customers, most casino sites provide an online slots bonus. They come in various shapes and sizes, and they all have different wagering requirements.

It always pays to search around for the best deals. For example, one site could offer a 200% welcome bonus up to £500 plus 50 bonus spins, implying that if you deposit £250, you’ll get £750 to play with and 50 additional spins.

A competitor may give a 100% match bonus up to £300, plus 300 extra spins. If you deposit £300 of your own money, you’ll get £600 to play with, plus 300 extra spins.

The wagering requirement, often known as the rollover requirement, is another essential factor to keep in mind. This refers to the number of times you must wager this bonus credit before you can withdraw funds.

For example: if you are given a £20 bonus with a 10x wagering requirement. This means you need to spend £200 on eligible slot games before you can withdraw any pending winnings gained.

When it comes to welcome offers or bonuses, there is often a time restriction on how long you have to bet the bonus before it is withdrawn from your account, so always verify the timeframe before betting. The time restriction varies from site to site and might range from 48 hours to 30 days on some slot sites.

You should aim for the highest matched deposit bonus, the most free spins, and the lowest rollover requirements possible. When it comes to casino bonuses, you usually have to make a compromise, but some sites provide an appealing, well-rounded bonus to entice new clients.

A free online slots no deposit bonus is also available at some online slots sites. If you come across a free online slot no deposit offer, take advantage of it since you will not have to deposit any of your own money, and you may be able to cash out if you are successful.

Mobile Slot Sites

The days of being connected to your desktop or laptop computer to experience the exciting pleasure of online slots are long gone. You can now play your favourite slot games at any time and from anywhere, thanks to advancements in mobile technology.

All you need is an internet-connected smartphone or tablet to play a broad range of slots, from traditional 3-reel to modern video slots.

In the last few years, the demand for mobile gaming has grown at an exponential rate. The best slot developers make sure that whenever they release a new game, it includes a mobile-friendly version.

We have picked out the best and most secure mobile slots sites in our full review and analysis.

You’ll never have to miss out on a chance to take part in the fun again. Standing in a post office queue or waiting for a friend won’t be a problem with mobile slots since you’ll always have entertainment at your fingertips, not to mention the chance to become a millionaire by playing a progressive jackpot game.

Most online slots sites are now HTML5-enabled, allowing them to be played on any mobile or tablet device and any operating system, including iOS, Android, and Windows Phone.

Many of the top online slots casinos offer specialised mobile applications, while others can be accessed via your mobile browser. Mobile phone usage continues to rise with each passing year, and mobile casinos are becoming increasingly popular.

Best Slot Sites with Low Wagering Requirements

Online slot sites are becoming more fair and open with their promotions as a result of recent regulatory pressure. As a result, we see an increasing number of casino bonuses with better and lower wagering requirements, and in some cases, no wagering requirements at all.

It is usually a good idea to plan out how you’ll meet the casino’s wagering requirements before you start on a new welcome bonus. Most of the time, you’ll have at least 30 days to complete this, which provides plenty of time, but shorter timeframes may cause you to miss out on funds.

If you’re new to online slots, we recommend starting with the casinos with the lowest wagering requirements. This will offer you a greater chance of wagering on time and converting your free spins bonus into cash.

For the more daring players who wager more significant amounts, this may not be a concern, but this will take longer on lesser stakes.

If you can find a slot site with a welcome bonus that offers a 30-day window to wager, this is generally enough time. You can always choose auto-spin if you don’t mind letting the slot run on its own.

The wagering requirement on your bonus is the most essential item to look for; the lesser amount, the better. Around 30 times is a decent figure online right now, although there are also alternatives for lower amounts such as 10 or 20 times.

Another critical factor to consider when looking at the wagering requirements is if they include both your deposit and the welcome bonus since this will double the amount necessary; ideally, you want wagering requirements that apply to the bonus.

High Payout Slot Sites

Slot machines are without a doubt one of the most exciting online casino games, but it’s important to remember that the main aim of players is to win. While online slots are mostly a game of chance, there is a way to improve your chances of winning.

You can be confident that a significant portion of your wagered money will be returned to you if you choose to play the highest RTP slots. As a result, you should always choose games with an RTP of greater than 96%. You may also check out various free casino games to see which ones are best for you. The casinos with the highest slot payouts, as well as the top three high RTP slots they offer, can be found on our best payout slots page.

However, keep in mind that all of the rewards shown are theoretical, and other circumstances might impact the maximum payment.

The maximum betting limit, bets per line, and bets per spin are all examples of these. Furthermore, wilds, free spins, bonus rounds, additional spins, and multipliers can affect the game’s maximum payout. As a result, in addition to a high RTP, you must always consider other factors that may impact the number of awards you receive.

You should also consider the availability of Android gambling applications, which may be pretty valuable in terms of convenience.

Payouts and RTP

Return To Player (RTP) is a term that indicates how much a slot machine pays out to players over a number of spins, generally represented as a percentage.

For instance, a slot with a 97% RTP will return £97 for every £100 wagered. So, this piece of information essentially reveals how much money you may anticipate losing when playing a specific slot machine.

Some slots may pay out money on practically every spin. In contrast, others may pay out nothing for 50 spins before hitting a huge win, bringing the RTP to the same percentage as the slot that pays out regularly, but they would score quite differently on the volatility scale. You can find out the latest slot games with the best return to player on our best RTP slot game page.

Players that favour high volatility slots are searching for huge winnings, which you can find on slot games with greater multipliers. Low volatility slots are popular with players when it comes to wagering bonuses.

Online Slot Games Variations

There are hundreds of different slot variations and themes available at your fingertips. A slot machine, for example, may have a progressive or non-progressive jackpot. Progressive jackpot slots have the potential to provide some incredible payouts. The money might be collected from just one game or from many slots, including multiple online slots sites, depending on the casino’s regulations.

With so many different types of slot games to select from, it’s important to know which one would best fit your style of play. This might range from large jackpot games to branded slots featuring your favourite movie characters.

Branded Slots

A branded slot has a theme based on films, television series/shows, music, musicians, board games, superheroes, or even cartoons.

The theme is easily recognisable and specific to a particular brand, in comparison to a general jungle theme for example.

Classic Slots

Classic slots refer to online video slots that resemble traditional-style slot machines. Many video slot software companies create new games based on classic slot machines.

Video Slots

Video slots are the most popular online slot machine, with these games consistently being the most popular at casinos and online slots sites. When you go to your favourite casino or slots site, you’ll see that most games are video slots.

Video slot games also include various features, including pay lines, slot bonus rounds, side games, stunning visuals, and even mini-games integrated within the main game. The software developers took a classic slot game and modernised it, giving it a far more engaging experience for online gamers.

Progressive Slots

Progressive slots are a category of slot machine with a massive additional jackpot that keeps growing with each spin of the reels.

It’s no wonder that progressive slots are one of the most popular types of play at online casinos, with jackpots that may reach millions of pounds

Boiling Point Jackpot Slots

When water reaches a boiling temperature, it begins to bubble and explode. When a boiling-point jackpot hits a particular level, one lucky player is rewarded with a massive payout in a similar way.

Autoplay Slots

The slot game Autoplay feature allows you to play a preset number of spins without interruption.

Autoplay can save players time, especially when looking to bet the welcome bonus as part of the wagering requirements.

3D Slots

3D slot machines are video slots with visuals that appear in three dimensions on the screen. You do not need to wear 3D glasses like when watching a film.

The game’s developers are aiming to provide this experience. The objective is to make the activity on-screen as realistic as possible.

3 reel classic slot machines

The classic 3 reel slot is based on the original physical machines. All slots were once classed as 3-reel machines. Mechanical operations, few paylines, and even fewer bonus rounds defined these ‘Classic’ games.

5 reel slots

5-reel slots, as the name implies, add two more reels to the traditional three-reel games. In addition, the extra rows added, allowing the player to hit more possible paylines.

Mega spin slots

Mega Spin slots are a contemporary spin on Vegas-style slot machines. Three of the series’ four slots have three reels and a single payline.

One MegaSpin slot machine is linked to the Major Millions jackpot system, allowing you to win a huge progressive jackpot with only one lucky spin.

Multipliers

Multipliers are special features featured in slot machines that can double or triple your wins by a specific amount. The primary goal of these is to increase your chance of winning, in some cases, by 100 or 1000 times.

Multi-payline slots

The more paylines a slot machine has, the more likely it is that players will win. Paylines in slots are simple lines on which specific combinations of matching symbols must appear in order for players to win and collect money.

Best Slots Software Providers

Online casinos have had a significant influence on the gaming industry, and the demand for high-quality online slots has risen dramatically in recent years. As a result, there are businesses dedicated only to developing slots software for online casinos.

We have put together a list of the best and most well-known online casino slot software providers:

• Microgaming – one of the most well-known name in online slots software creation, and while the business is still among the industry’s top names, its clout has waned slightly. Despite this, they have hundreds of slots and are adding to that number all the time.
• NetEnt – The Swedish firm is responsible for creating a mix of licensed and unique games, which has proven to be a popular choice among gamblers who love their games. NetEnt also offers some of the best progressive jackpots available anywhere in the world.
• PlayTech –  Risen to the top of the casino slot software development industry since 1999 and are now one of the world’s largest gaming software development companies.
• Play’N Go – Many people are familiar with Play’n Go because of their mobile software, but their games are also available at many online casinos.
• Yggdrasil Gaming – Formed in 2013, Yggdrasil is the newest addition to the list of the top software companies. Their slots all have a distinct design and excellent visuals, making them highly enticing to a wide range of players.
• IGT –  One of the largest slots software development firms is responsible for some of the greatest slot games available in brick-and-mortar and online casinos.
• Novomatic – This software firm company was founded in 1980 in Austria and has since expanded throughout Europe and Asia. Their slot machines are now available in online casinos.

Online Slots Tournaments

Slot tournaments are competitions between players of our video slot games at online casinos. You may participate in tournaments to see who the best slot gamer is, just like when players compete in poker games. A slot tournament is far more reliant on luck than strategic poker games.

The Tournaments will have a time limit for accumulating points and may need a buy-in to participate. So, when you’ve paid in, you’ll need a lot of luck to win since you’ll be trying to win as much money as possible to earn points and advance up the leaderboard.

Some casino sites may provide free tournament entries, allowing you to join in the action without having to buy in.

Prizes vary between slot sites and tournaments, but the most frequent is a cash prize for the top finishers, with free spins or bonuses awarded to the other participants, some of which are earned during the tournament itself. This may be a lot of fun for slot enthusiasts, and there are some amazing prizes to be won, but as with other casino games, chance and strategy are necessary!

Online Slots Rules: How to Play Online

The method of playing slots is the same, whether you play online or offline: you deposit money, make a wager by pulling a lever/selecting a button, and then win or lose based on a combination of spinning reels.

A random number generator determines the combination you obtain after you put your wager (RNG). RNGs imply that the outcomes of slot machines cannot be anticipated. Thus your chances of winning at any particular machine are the same whether you’re wagering for the first time or the thousandth.

On land casinos, you put your bet by inserting money into a slot on the machine, hence the name. Land-based casinos use a monetary system to operate their slot machines.

The action in slot machines comes from columns of images – traditional slots are known for employing representations of fruit, which is why they’re called “fruit machines.” Each column of pictures on a slot machine is known as a reel, and the rule for getting a winning combination is to construct a line (also known as a payline) from your reels.

When playing slot machines, the number of possible winning combinations is determined by the number of paylines you choose. For example, on a three-row slot, choosing one payline means you’ll need a winning combination from the centre reel, two paylines means you’ll need a winning combination from the top and bottom. Three paylines means you’ll need a winning combination from all three rows.

•  Mega Fortune – NetEnt.
• Mega Moolah – Microgaming.
• Mega Moolah Isis – Microgaming.

We generally tend to recommend the best software providers around however there are occasionally new kids on the block with huge progressive jackpots and welcome offers.

Slots Payment Methods

One of the main areas of concern for many players when it comes to playing online slots is making safe online payments.

As a result, we only suggest online slots sites that provide players with various safe banking alternatives. This is especially true now that the government has passed new regulations prohibiting UK online gaming companies from accepting credit card payments (although debit cards and wire transfer are still accepted).

The best online slots sites will provide you with a wide choice of deposit and withdrawal methods. Visitors to online slot sites in the United Kingdom frequently use credit and debit cards to make purchases.

You may also use an e-wallet like Neteller or PayPal, but you will likely be unable to collect a bonus if you use Neteller or Skrill. This is done to keep bonuses from being abused. Many new online slots sites allow vouchers like a PaySafeCard, as well as other prepaid cards.

Withdrawal times differ based on the online casino and the withdrawal method used. Bank transfers are typically much faster than receiving a check via post. Because this is a licensing requirement meant to prevent money laundering, you should expect to receive withdrawals using the same method to make a deposit.

Slots Random Number Generator (RNG) and How it Affects the Games

Random Number Generators or RNGs determine the outcome of all online casino games. The RNG is a microprocessor, similar to those used in desktop computers, whose primary function is to choose numbers from within a specific range.

Typically, the RNG generates and chooses numbers ranging from zero to many billions. Using a predefined algorithm, the software generates lengthy sequences of random numbers many thousand times each second.

Regardless of how long the jackpot has been unclaimed, no online slot is ever due for a hit. The RNG is only interested in numbers and is unconcerned with the amount you wager. Whether you play with extra credits or not has no bearing on the program. In the interest of fairness, the RNG is employed to ensure that all players have an equal chance of landing a winning combination.
