How I choose the best casinos to play online slots

Given that the vast majority of UK online casinos feature slots, it is not easy to separate the best from the rest. However, when choosing which slots are best for you, be sure to consider the following factors, among others:

• Bonuses available
• The RTP percentage (look for over 96%)
• Amount of slot games available
• Which slot providers are listed (NetEnt, Microgaming, and Pragmatic Play being the most popular)

How do online slot reels work?

Reels are the vertical sections of a slot that spin top to bottom once you have placed a bet. It is here where symbols will land, potentially forming winning combinations. Most slots now come with 5 reels, along with 3-4 rows. However, classic slots generally have 3 reels and the same number of rows.

What are the most common slot game types in UK online casinos?

We have already mentioned the great variety of slots that are available to players in the UK today. This is thanks to the increasing number of game types. Below, we take a closer look at the most common types of slots: 

Regular slot games

Known as video slots, this is the most common form of slot available online. They feature additional types of media, along with the traditional reels and buttons. They are animated and often feature standout graphics and sound effects. As a result of such factors, they are often compared to arcade-style games. Those playing video slots may well be able to take advantage of different levels, bonus rounds and paylines. Starburst, Mega Moolah and Book of Dead are prime examples. 

Free slot games

Many slots now come with demo modes. This makes it possible to play for free, ideal for beginners. It also caters for those simply looking to play for fun. Of course, there are no opportunities to win real money. However, you will also not put your own cash at risk. Free slot games are available on both desktop and mobile in most cases. 

Mobile-specific slots

Given the demand for mobile slots, some developers create games that are specific to smartphones and tablets. Meanwhile, the majority of slots are now available on mobile devices, thanks to HTML5 technology. 

Megaways slots

One of the latest forms of slot available online is Megaways. Big Time Gaming was the first software provider to create such a game. Today, many other developers have followed suit. Megaways slots come with up to 117,649 paylines, along with additional features, such as cascading reels, free spins and multipliers. White Rabbit Megaways, Gonzo’s Quest Megaways and Big Bass Bonanza Megaways are popular examples. 

Jackpot slots

With this slot type, a proportion of each bet is added to the jackpot. As such, they offer large payouts, often reaching millions of pounds. However, with higher variance, your chances of winning are smaller. Despite this, Aztecs Millions, Mega Moolah and Cleopatra’s Gold remain hugely popular.

⚡ Best slots at UK casino sites

Now that you understand the different types of slots available, it is time that we discuss some of our favourites. Below, we have given our top 10 slot games, along with a quick guide on how they work:

1. Book of Dead

Created by Play’n GO and released in 2007, Book of Dead has long been one of the most popular online slots. With an RTP of 96.21% and 10 paylines, Book of Dead theme centres around Ancient Egypt. Bets can be placed between 10p and £100 per spin, with the maximum win being 5,000x your stake. With high volatility, players can look forward to regular payouts. Book of Dead’s graphics are excellent too, with the slot having been optimised for mobile use. 

2. Starburst

Starburst comes from NetEnt and attracts players thanks to its regular payouts, expanding wilds and colourful design. The RTP is 96.1%, while 10 paylines are spread across five reels. The top win is 250x your bet, with a re-spins feature also being available. Released back in 2012, Starburst features on many of the best slot sites in the UK. 

3. Mega Moolah

Powered by Microgaming, Mega Moolah is a jackpot slot that features an African Safari theme. With 25 paylines, a maximum win of 1,955x and two bonus features, there is much to like about Mega Moolah. The RTP is just 93.42%, which is to be expected from a jackpot slot. Mega Moolah holds the record for the highest ever jackpot win, at over £16 million! 

4. Big Bass Bonanza Megaways

The first Megaways slot to make our list comes from Pragmatic Play. With up to 46,696 paylines, six reels and a top win of 4,000x your bet, this is a remake of a popular video slot. The underwater theme is nicely done, with both free spins and multipliers being on offer through bonus rounds. This slot also comes with a variable RTP, between 94.62% and 96.7%.

5. Gates of Olympus

Also from Pragmatic Play is Gates of Olympus. Set on six reels, this highly volatile slot comes with an Ancient Greek theme. Bets start at £0.20, rising to as high as £100. With a top win of 50,000x, it is easy to see why many players enjoy this slot. You can also trigger free spins and multipliers when playing Gates of Olympus. 

6. Bonanza Megaways

Arguably the most popular Megaways slot on the web is Bonanza Megaways. Developed by Big Time Gaming, this 6-reel slot features up to 117,649 paylines! With three bonus rounds, a 26,000x max win and unique design, Bonanza Megaways is something of a cult classic. There really are no faults with the game, with it being mobile-friendly too. 

7. Gonzo’s Quest

From the might of NetEnt, Gonzo’s Quest is a visually pleasing slot that comes with up to 15x multipliers in free spins, a 2,500x top win and medium volatility. Based in the lost city of gold, the aim is to find the El Dorado character. Gonzo’s Quest also comes with an avalanche feature, wild substitutions and free fall wins. 

8. Immortal Romance

Launched by Microgaming in 2011, Immortal Romance features 243 paylines, a maximum win of 12,000x your stake and four bonus rounds. With a unique theme, based on the vampire genre, Immortal Romance is one of the best slots in terms of visuals. The RTP of 96.86% is also appealing, while a demo mode can be utilised too. 

9. Aztecs Millions

Created by Real Time Gaming, Aztecs Millions has 25 paylines and a progressive jackpot. Released in 2009, up to 25 free spins are also available, while the non-progressive jackpot is 5,000x your bet. Bets are fixed at £5 per spin, with 5x logo scatters needing to land in order to trigger the jackpot. 

10. Sweet Bonanza

Our final pick is another slot from Pragmatic Play. Sweet Bonanza is certainly colourful, while also offering 8 paylines, a 21,000x top win and cascading wins. Set in a land of candy, the catchy soundtrack helps to keep players entertained too. The RTP is 96.51%, while the volatility of Sweet Bonanza is high. 

How many paylines do online slots have in the UK?

The number of paylines vary greatly between online slots. Players in the UK are in a position to bet on classic slots, featuring just a single payline. Meanwhile, Megaways slots can feature as many as 117,649 paylines. While it is nice to know how many paylines are available, it should not be the sole reason for playing a particular slot. 

Slot volatility : what it is and why you should care

Volatility refers to the risk of a slot. This is because some games are less predictable than others. Slots are either low, medium or high in this area. Low volatility slots will pay out more regularly, albeit in smaller amounts. Meanwhile, a high volatility slot will pay out less often, but the amount will be considerable.

What welcome bonus is the best for slot players?

It is important to know the difference between them before you get started. Below, we have outlined the most common symbols: 

• Scatter symbols – Scatter symbols are used by developers in order to deliver bonus features to players. The exact rules vary between games. However, scatters often trigger bonus rounds, where free spins and multipliers can be won. 
• Standard reel symbols (classic symbols) – fruit symbols, card symbols, food, diamonds, etc.
• Wild symbols – Wilds can substitute all other symbols in most cases. As such, they can be used to form winning combinations. For example, matching symbols appear on reels 1 and 2, before a wild lands on reel 3. 
• Multiplier symbols – Simply put, multiplier symbols will multiply your earnings by a specific amount. They are generally instantly recognisable. 
• Bonus symbols – Such a symbol will activate a bonus round, where additional features and greater payouts are available.

Book of 99, 1429 Uncharted Seas, Blood Suckers and Jokerizer are among the best in this area, coming with an RTP of 99%, 98.6%, 98% and 98%, respectively.

Which payment methods can I use to play online slot games in UK casinos?

If you wish to win real money from online slots, you will first need to deposit money of your own. The best casinos in the UK accept a variety of payment methods. These include debit cards, e-wallets and PayViaPhone. It is important to select a casino that processes payments quickly, especially withdrawals. Also consider any potential fees and whether a potential payment option is eligible for bonuses. 

Which slot game developers make slot games for UK online casinos?

These include Microgaming, NetEnt, Pragmatic Play, Big Time Gaming and Play’n GO. Such software providers are known for creating entertaining, rewarding and visually pleasing slots.

Can you play slots on mobile?
