Best Slots Sites Guide: Everything You Need to Know

Get all the info about the Slots machines sites in the UK: games, bonuses, best mobile apps. Our expert made a complete slot guide for all the UK players.

What Are the Most Common Types of Slots Games?

The types of online slots games that are out there vary based on a number of factors. Those factors can include the denominations the game is being played for, the number of reels that can be spun, the type of game that is being played, among other factors. Here is a breakdown of the different types of slot games that are available at the best slots sites.

What are denominations?

Denominations can vary in online slots games based on what game you are playing. They can vary from a simple penny slots game, which is rare in the current online slots arena, all the way to higher stakes games that accept multiple betting units per spin. Higher stakes games have become more common in the present era of online slots. As you would expect, the higher the amount wagered, the higher the payout you can receive generally is.

What types of games are available?

The number of reels that can be spun on each turn can also vary. Most commonly you will see three and five-reel slot games at the best slots sites. Although there also exists the occasional machine with six or seven reels. What type of slots game you are playing can also vary, as players can enjoy the basic machine with pictures of fruit or can get involved with video and 3D slots to spice things up.

Perhaps the game types that draw the most interest surround the different types of jackpots that are available at the best slots sites. Both standard and progressive jackpots have become common in the industry, with both having their benefits. Standard jackpot slot games offer smaller payouts traditionally, but may be less expensive per spin to be in line with that. Progressive jackpot games, meanwhile, feature payouts that increase with every wager made by the community. In the case of online slots, that means that bets made around the world have an impact on how the jackpots increase.

What are single and multi-coin slots?

Single and multi-coin slot machines are both common in online slots, with multi-coin machines usually being more popular. Players have the opportunity to use several betting units, usually up to five, per pay line. The more pay lines used, the better the player’s chances of winning on a given spin. This is an interesting way to play, as players are able to determine their own win probability in a way.

How Do You Play Online Slots Games?

Playing online slots games is easy, with the best slots sites offering something for everyone to enjoy. Here, you will learn the basics of playing online slots so you will know what to expect right from your first spin.

How do I bet in online slots?

The first thing you will want to do is set a bet size. Depending on the type of game that you are playing, this can be done in one of two different ways. The first way would be to simply choose a bet size for a single unit game. For multi-unit or multi-coin games, you will have the option to choose how many units you want to place on each pay line you open up. Perform this step with the idea in mind that you do not want to exhaust your budget right away, but want to make sure you can get a decent payout out of your game of choice also.

How do pay lines work?

For multi-pay line players, the next step is to choose the number of pay lines that are available to you. Generally speaking, the more pay lines that are opened up to you, the better your probability of winning on a given spin. This is because each pay line represents a different way on the screen that symbols can match up to result in a winning spin. Be sure to check your game of choice ahead of time to find out what pay lines are available so you can see the directions in which symbols can match up for you to win. The best slots sites offer games that clearly display this information before you start spinning.

How do I win in online slots?

You are almost ready to spin, but first you should know what to look for when you do. Each game has a different set of symbols that will activate payouts when the right combinations appear. Be sure to take a look at the pay table for each game you play ahead of time to see which symbols correspond with different payouts. Also, be sure to know what your wild and bonus symbols are ahead of time, so you are not surprised when they are activated. Again, the best slots sites will make this information readily available so you know how to win at each game ahead of time.

From there, it is time to start spinning. Some players like to keep spinning as quickly as possible in the hopes that they are able to rack up some winning spins quickly, while others like to play slowly in hopes that they can get their funds to last a decent amount of time. How you play with regards to the pace of your spins is up to you, but now you know how to play online slots.

Can I Play Online Slots on My Mobile Device?

Absolutely, you can play online slots on your mobile device! The best slots sites realise that players no longer want to be tethered to a computer in order to be able to play slots online. For that reason, many of them offer mobile versions of their sites so that players can take their favourite online slots games wherever they go. There are some things to be aware of when it comes to these mobile sites. Keeping these tips in mind will ensure the best mobile slots experience.

Is there anything I should know about playing online slots on my mobile?

First, mobile versions of the best slots sites feature fewer games than their desktop counterparts. This is a product of the fact that not every online slots game is compatible with mobile devices as of right now. This is a situation that is rapidly improving, as sites continue to optimise their games for mobile before they do so for desktop at this point. That decision is fuelled by the fact that more and more players want to take their slots with them. The online slots landscape has evolved, and mobile slots are certainly the future.

For players who want to play mobile slots right now, they should do their research. Find out which of the best slots sites offers the most games for mobile devices. Once they have that information, it should be smooth sailing in deciding which of the best slots sites is right for them. Of course, other factors have to be considered as well, but the quantity of mobile slots games should weigh into the decision.

Apart From Signup Bonuses, What Other Types of Bonuses Are Available?

There are many different types of online slots bonuses that go far beyond the reaches of signup bonuses. For players who want bonuses beyond just their first deposits, these options should do well. There is something for every step of a player’s time with the best slots sites. From account reloads, to loyalty bonuses, and more, making sure the slots site of your choice has these bonuses can be a make or break part of your online slots experience.

What are deposit and reload bonuses?

Deposit and reload bonuses are perhaps the most common type of bonuses available at the best slots sites. Players will receive a bonus good for a percentage of a deposit to reload their accounts. These deposits are usually good up to a certain amount of funds, which gives players the ability to make a deposit that will get them the maximum bonus or one that will earn them a smaller bonus. At the end of the day, the ability to receive a bonus just for reloading an account is always a positive, as it incentivises a player to do something they may have already intended to do.

What are some other bonuses in online slots?

Another common form of bonus comes in the form of a no deposit bonus. Players who frequent the best slots sites may receive no deposit bonuses according to the terms of the site. These usually come in the form of bonuses that are available on specific days of the week or on certain games on a promotional basis. Rather than giving out funds with these bonuses, players generally receive no deposit bonuses in the form of free spins. These are fun ways to potentially rack up a little extra cash without having to make a material risk on the front end.

Other forms of free spin bonuses are also available, as they can be awarded as a form of bonus when a player makes a deposit as well. These are great for players who want a little extra something on top of a financial bonus when they make a deposit.

In addition to the above bonus types, players can also take advantage of the bonuses that come with loyalty programs. Most of the best slots sites have some kind of loyalty program to take advantage of. As players continue to use the online slots site of their choice, they have the ability to move up the ladder when it comes to those loyalty programs. The higher up the loyalty structure a player goes, the better the chance they have of receiving bonuses. Some of these loyalty bonuses can come in the form of deposit bonuses, reimbursements on deposits at the end of each month, free spins, and many other forms. This is the best way for frequent players at the best slots sites to make the most of their time there.Slots

How Do I Sign Up to an Online Casino?

  • Go to one of the best slots sites of your choice.
  • Read the rules and terms and conditions of the site.
  • Click the button that says Join or Sign Up at the top of the site.
  • Fill out the information requested and verify as needed.
  • Make your first deposit.
  • Start playing online slots!

Online Slots Reviews

In order to identify the best slots sites our casino experts did a punctual analysis of Uk Casinos offers. In the following paragraphs you will find their opinion about the best casino app, the best bonuses, the Customer services and games.

Online slots bonus: Best sign-up offer

When it comes to the best sign-up offer among the best slots sites, Spin and Win simply cannot be rivalled. The site has a welcome bonus that blows the doors off of its competition. Spin and Win is offering players a jaw-dropping £500 in bonus funds on their first deposit on the site. If a player was to deposit £10 their first time, they would start playing at Spin and Win with a huge bonus up to £500. 

Mr. Play’s welcome bonus also deserves a mention here as one of the best slots sites is also offering a strong welcome bonus. But there is just no way that another site is going to be able to contend with that giant offer from Spin and Win. And, by the way, Spin and Win offers its players another £500 in bonus funds on their next two deposits. The second bonus is good for 100% with up to £250 in bonus funds, and the third deposit bonus is worth 100% with another £250 in bonus funds up for grabs. There is no overstating how good this sign-up offer is, and it puts Spin and Win in the lead among the best slots sites.

Online slots games: Who has the best variety?

Variety is absolutely the name of the game in the online slots industry. With slots games looking similar to the untrained eye, a site needs to have a real wide array of games to keep players interested and coming back to play. Fortunately, all of the best slots sites offer a solid variety of games to choose from. But one of these sites managed to just point their noses out ahead of the competition to solidify their place as the site with the best online slots variety.

Mr. Play takes this category on both the sheer number of games that they offer and their quality. In all, players at Mr. Play can take part in over 500 different games, with the vast majority of those games, as usual, being online slots. Nearly all of the online casinos we’ve mentioned have hundreds of games to choose from, as one would expect from the best slots sites. But the ability of Mr. Play to push their number of games, while also making sure not to compromise in terms of quality makes them a major player when it comes to game variety.

Also helping Mr. Play is the fact that they boast some of the best progressive online slots. Of course, jackpots can vary based on the day. Depending on when a jackpot was last won and a number of other factors. So, your mileage may vary. However, with so many high-quality titles to choose from, players will feel like they hit the jackpot at Mr. Play.

casumo have the best slot variety

What is the best mobile app to play online slots?

Having a mobile app is not necessarily a requirement for online slots players anymore. The reason for this is the fact that players can now just use a mobile version of the best slots sites to get their action in from anywhere. This move toward optimising mobile slots sites without requiring an app has been a smart one, as players can get the same games without having to download anything.

In this battle of the best slots sites, Mr. Play gets the nod for having the best mobile site. The site was clearly designed with mobile users in mind first, as evidenced by the menu on the side of the screen. The functionality of the mobile website mirrors that of its desktop counterpart perfectly. Unsurprisingly, everything at Mr. Play scales down perfectly regardless of what device is being used. Details like this make it easy for mobile users to get involved with the best slots sites. So, Mr. Play deserves plenty of credit to that end.

At this point, websites in any industry would be remiss if they did not feature a design that is fully responsive. In the online slots world, this means having games that work without any issues across different device categories. It also means menus that are easy to navigate no matter which device is being used to view the site. Sites like Mr. Play, with their attention to details, are not only making things easier for their players, they are making things easier for those who are trying to figure out where to open an account.

All of this comes with the caveat that not every player is going to want to play on mobile. Some online slots players do prefer desktop action, which is fine. The key is to make sure that you know that whatever sites you play your slots on will offer support on your devices.

Which online slots site has the best customer service?

Customer service is key on any online slots site. Fortunately, the best slots sites all seem to have that memorised, as they all have solid customer service portfolios.

VideoSlots earns the title of having the best customer service among the best slots sites, though. They tick all of the boxes you would want from one of the top slots sites. Their customer service is available 24 hours per day, and they offer live chat services to go with their more traditional methods.

Matchbook also has a solid customer service situation, with a help section for players to browse through before they reach out to a person with an inquiry. For players who are new to online slots, this resource is extremely valuable. Not only does it prevent the need to make a phone call to answer your question, but it can also help you learn about slots sites. By reading the answers to your questions and items that you otherwise did not know about, you will become very knowledgeable about slots sites.

At this point, the more trusted slots sites will have some kind of phone, email, and live chat services available. It is important to find out what the hours are for each site you are interested in. This will make sure that you are able to use these services when you need them. After all, having a site’s customer service be closed when you need it is anything but helpful.

Furthermore, making sure that each site you want to play with has the methods you want to use for customer service is a huge deal. If you prefer to chat with someone as opposed to calling them on the phone, you need to make sure you use a site with live chat functionality. Otherwise, you are going to be stuck feeling uncomfortable every time you have an inquiry.

Customer Care

Best Slots Sites – FAQ

Generally speaking, it is definitely safe to make deposits and withdrawals at online casinos. However, doing so underscores the importance of using a trusted online casino brand. When using one of the best slots sites, you are working with a trusted brand in the industry. As such, those sites are regulated and subject to oversight from the UK’s gaming commission. A part of those regulations is making sure that their deposit and withdrawal services are secure, to ensure the financial safety of their customers. Failure to abide by those regulations can result in severe penalties against the best slots sites. These sites also have reputable customer support in place to resolve any inquiries related to deposits or withdrawals.

On the other hand, going with a casino brand with less of a reputation can result in players not having the same level of security. Anyone can start a website that looks like a reputable slots site. Making sure the one you choose is licensed and in compliance with the rules that are out there for online slots sites is extremely important. This is not something you want to check after the fact. Taking the time to do so before signing up to any slots site is a great decision.

This highly depends on how much you actually wager and on the type of slot you are playing. But mostly you need to look at the RTP percentage of a slot. The RTP or payback percentage is a calculation of how much the machine expects to pay back to the player over time. For example, if a game has a 95% RTP percentage, over the long run, the slot will pay back 95% of its winnings. The other 5% is the house edge. That’s how much the casino expects to keep to itself.
