Leo Vegas may be the number one online casino in the UK, so it’s hardly surprising that their slots offering is of the highest quality.

If you’re hungry for slots, Leo Vegas will feed your appetite. With lots of three-reel and five-reel slots, there are over 600 titles to be played, including many big-name features, such as Book of Dead, Starburst, and Mega Fortune Dreams.

Slots users may be pleased to learn that Leo Vegas’s welcome bonus includes 50 free spins on the popular title Big Bass Splash. When you register for an account, you can also receive up to £100 in bonus funds.

There’s zero question of safety or reliability, and Leo Vegas has been one of the most tried and trusted slots sites in the UK for over a decade now. It is licensed and regulated by the UK Gambling Commission.

Overall, Leo Vegas, available on desktop and mobile, has high rates based on what it offers players. However, there are a few minor drawbacks, including the fact that there aren’t too many payment options, although both PayPal and Apple Pay features are positive.

Established in 2017, Casimba is one of the newer online casinos in the UK, but it certainly doesn’t rank poorly as far as we’re concerned.

If you’re looking for online slots, you’ll be pleased with what you find at Casimba. With over 750 slots to enjoy, Casimba offers more variety than many of its competitors. The slots are easy to play, and the graphics are good, too, thanks to lots of high-quality software.

There are, of course, lots of minor and niche online slots, but those looking for the big features won’t be disappointed, as you’ll find Big Wheel Bonus, Book of Dead, Gonzo’s Quest, Diamond Royale and Wild Portal, to name just a few.

Casimba’s welcome bonus is where it beats the competition. New slots players who register for an account at Casimba will be rewarded with a 100% deposit bonus on their first deposit, up to a maximum of £200. In other words, deposit £200 when you first join and get £200 in bonus funds. Better yet, you’ll also receive 50 free spins.

Casimba has a few other nice touches. First, the live chat is available 24/7, so you can get an answer to your query even at night.

Withdrawals are also fast, with most players reporting a withdrawal time of 24 hours or less. However, UK players have a weekly withdrawal limit of £5,000.

#3 – Plaza Royal UK Slots Site

BONUS

Up To £200 + 100 Extra Spins

80%
TOTAL SCORE

Plaza Royal, one of the newest UK slots sites, was established only in 2020, but I don’t think it has little to offer for a second.

On our overall list of UK Online Casinos, Plaza Royal ranks third, and there’s good reason for that.

The welcome bonus is great for starters, with new players getting up to £200 in bonus funds. Online slots players will be encouraged to see that they get 100 free spins when they sign up, double the industry norm of 50 free spins.

There’s plenty of table action to get stuck into, and the live casino options are good. However, if you like online slots, there’s enough to entertain you. Plaza Royal has tons of slots featuring three- and five-reel games. Popular titles include Golden Jokers, Buffalo Hold, Dynamite Strike, Book of Dead, and Eye of Horus.

You know you’re also playing with a safe site, as Plaza Royal is fully licensed by the UK Gambling Commission.

If we have one criticism of Plaza Royal, then it is the fact that the live chat support doesn’t work 24 hours, though if you have a query during the chat isn’t available, you can direct it to support@Plazaroyal.com.

#4 – Videoslots UK Slots Site

BONUS

100% up to £200 Bonus

FREE SPINS BONUS

11 Welcome Spins

TOTAL SCORE

Founded in 2011, Videoslots doesn’t necessarily have the big reputation of Leo Vegas or Betway Casino, but it is no longer a back number. This UK casino is one the best as far as we’re concerned, especially regarding online slots.

If you seek variety from your online slots provider, you’d be hard-pressed to find something with more options. Videoslots offers over 7,000 titles. All the big-name progressive slots, such as Classic Fruit, Lucky Diamonds, Cash Crazy, and Double Whammy, can be played, as can many lesser-known slots. There are also casino and table games, such as blackjack and roulette.

The action doesn’t stop there, oh no. There are jackpots and scratch games, too, including titles such as Gold Rush, Diamond Rush and Happy Scratch.

The welcome bonus is quite appealing. When you register as a new player and join Video Slots, you’ll get a 100% deposit match up to £200, which is more than the industry norm and certainly one of the better welcome offers.

Videoslots is licensed by the Malta Gaming Authority and the UK Gambling Commission, So It is reliable and safe.

Videoslots has many plus points. There’s a massive selection of games and a huge number of software providers, which helps with the variety. While they may be the king of online slots, they have many options.

The downside, however, is that the website is a little dated and lags behind some of its main competitors in that respect. However, you won’t find too much to complain about if you can get past that.

#5 – Betway Slots UK Site

BONUS

100% Match Bonus up to £50

80%
TOTAL SCORE

In the UK, Betway is one of the biggest online slots brands. From sports betting to casino games and online slots, Betway has it.

With many slots and casino games, Betway Casino rates as one of the best UK slots sites. You may not find as many options as you would at Leo Vegas or Video Slots, but that doesn’t mean the options are lacking, and you’ll still find all the biggest and most popular titles.

The new-player bonus at Betway Casino is far from disappointing. If you’re signing up to try your luck on the slots, the welcome offer is a great way to boost your starting funds.

Register for an account to take advantage of the welcome offer, and Betway will give you a 100% deposit match up to a maximum of £50. If you deposit £50, you’ll get £50 in bonus funds. Likewise, if you deposit £25, you’ll get £25 in bonus funds.

One of the main reasons Betway Casino is so famous for online slots is that it is easy to use. Both the desktop site and the mobile betting app feature slick designs. In truth, there aren’t any negatives for UK players.

What are online slots?

Online Slots UKIf you’ve ever been to a brick-and-mortar casino, you’ll know what a slot machine is. It is that little machine that you see flashing bright lights, sit in front of, and pull a lever, hoping that the symbols will match up and you’ll become a winner. Online slots are the same, except you can use them from home on your PC or mobile.

While real-life slot machines often come with three reels, an online slot machine takes this further. The concept is the same, where you will spin the reels so the symbols match up, but you can add a ton more reals and other special additions, which can lead to bigger winnings.

How do online slots work?

To play online slots, you first need to sign up for an account at the online casino of your choice. Once you have done so, you will need to make a deposit. This deposit can be any amount under the casino’s maximum and should only be what you feel comfortable spending. After you have money in your account, you can play a fun and exciting online slot.

As mentioned, you’ll often find most physical slot machines with three reels. Online slot machines have the same but can also come with many more, depending on the game. To start a game, you must stake the pay lines from your deposit amount and then spin the reels. You will know you’ve won money when the symbols on the reel match up. It will often need a minimum of three matching symbols, but this can depend on the game.

Online slots have no logic or strategy, and you can’t do anything to ensure you win. If you’re playing at a trusted online casino, it will have a random number generator built into its system. Each outcome is entirely due to luck; there is no way to rig the game and ensure the symbols match up. It makes the game much more thrilling and is fair for every player on the site.

Online Slots Terminology

You may come across some specific words and terminology when playing online slots, and it is useful to know what they mean to get the most out of your gameplay. Below are some of the most common terms associated with online slots:

Blank

You’ll find a blank between your symbols when unsuccessful at winning.

Bonus

A bonus provides you with a special chance to increase your winnings. You may receive free spins or credit to your account to use on a game.

Coin size

The value of the bet you have placed on the online slot.

Credit meter

How much money or game credits have you left in your account to use on the online slot?

Jackpot

The most money you can win from the online slot.

Paytable

The table shows all the potential winnings you can earn in a specific online slot game.

Payline

Your matching symbols need to land on a pay line so you can win.

Reels

The horizontal columns in the game display the symbols.

Scatter symbol

A scatter symbol can unlock a special bonus anywhere on the reels.

Finding a Reliable Online Slots Site

Finding the perfect online slots casino is best once you’re ready to start playing slots. You want one that is reliable and fair, so you can follow these steps to ensure you’ll be getting the most out of your experience:

Look at reviews

The best way to tell whether an online slots casino is reliable is to look at what other players have said about it. Searching for site reviews will tell you all you need to know about the casino and its online slots. Other players will also say how good the payout time is and whether the games are fair.

Check it has a license

A reliable online casino will be licensed and registered with an authority. If the slots casino has no license, you should avoid it at all costs. The licensing should be mentioned somewhere on the website, but it can be difficult to find, so your best option is to use Google or see what the reviews have said.

Choose quality over quantity

You may be drawn to the online slots casino that offers over 1,000 slots to play. However, don’t let this tempt you. Often, it is too good to be true, and they may not have great payouts or RTP rates. It is best to go for a trusted online casino with fewer quality slots than those offering everything.

Review banking options

Some banking options are more reliable than others, and you should only use online slots sites that offer deposit and withdrawal methods you are comfortable with. A casino that offers the typical debit and credit card options is likely reliable. However, you can also double-check these by looking at the reviews.
