Slots are the most popular online casino games, and that’s why many online casinos stock slot machines. However, without due diligence, you cannot distinguish the best UK slot sites from the hundreds of online sites that claim to be the best.
Here’s a guideline on how to identify the best UK slot site that is ideal for playing your favorite slot games. Some of the main features that you should look out for include:
You need to sign up at a slot site that caters to your gaming needs. As such, you should sign up at a UK slot site that stocks all your favorite slot games and more.
The best UK slot sites should also have a good variety of games from multiple software providers. This allows you to access all the games under one roof instead of registering at multiple sites.
But number and variety alone are not enough. The UK online slots sites games should also be high quality and fair to achieve the gaming experience players are looking for.
Confirming that the online slot site is legitimate protects you from losing your funds while playing the best slots at the site. The best UK slot sites must have acquired licensing from the UK Gambling Commission and/or other relevant gambling agencies.
The best bonuses for slots should be beneficial to slot players. For instance, the best UK slots bonus should include many free spins and spins with a reasonable value. In the case of deposit bonuses, the bonus offer should include a high match percentage such as 100% or 200% matched to your deposit.
The maximum wins attached to the slots casino bonus should also be high to avoid having to forego most of your winnings. While claiming the slots bonus, it is also essential to consider the wagering requirements, especially game weightings. Slots should contribute 100% to meeting the wagering requirements.
But that’s not all. The bonus validity period is also curial. The UK slot site should give you enough time to complete the wagering requirements.
All slot games are developed with specific statistics, including the RTP (Return to Player) rate, which determines how much the slot game is expected to give the players.
The best UK slot site should transparently display information about the slot game RTP so you can choose games with favorable RTP rates.
You should be able to gamble on the go on your mobile smartphone or tablet.
The best UK slot sites optimize their mobile casino slots, allowing players to wager on the games from wherever they are.
The best mobile UK slot sites should also be fully functional. That means you can make deposits, play on the go, and be able to withdraw your winnings from wherever you are on your mobile device.
You need a UK slots site that caters to its players’ needs and gives them access to efficient services. The best UK slot sites should ensure that your funds are secure and that you can withdraw your winnings without any problem.
The UK slot site should also have convenient payment options and banking limits that suit your gaming needs. In addition to secure banking options, the UK online slots sites should also attend promptly to its customer complaints.
You should be able to access customer support services whenever you require them. And the site needs to have several options that make it easy to do so. This could be through telephone, live chat, or email options.
Slot machine games are some of the oldest and simplest games in the online casino games industry. To a large extent, they are games of chance, and both novices and experienced casino players can play. Their popularity also stems from their features which include:
There are thousands of online slots casinos that you can find at the best UK slots websites. The games come in many varieties, from branded slots to simple classic slots and video slots with sophisticated graphics and storylines.
The slots, developed by the many software developers, also come with unique features that differentiate them from others. For instance, Big Time Gaming’s Megaways or Betsoft’s 3D slots stand out from the regular slot games and contribute to breaking the monotony by getting you a variety of slots with unique features.
Slots may also be developed with diverse bonus features that include free spins, wilds, and jackpot prizes, among other features.
Slot games do not require prior skills of playing them as they are games of chance. To win, you simply have to match symbols across the reels.
Any player can quickly sign up, click on a slot, place wagers and get the reels moving. The gameplay is unlike poker or other games where you need to make decisions or count cards to influence the game’s outcome.
Slots are some of the best casino games where you can reap great rewards. For instance, slots that feature progressive jackpots such as Mega Moolah and Divine Fortune reward players with huge wins, rising to millions of pounds.
Players do not also have to place large wagers to win slots jackpots, unlike in some games.

Software developers have come up with entertaining slot games that follow a familiar theme from a Television program, films, music, or music band.
For instance, the Game of Thrones slot game follows the familiar theme in the Game of Thrones American drama series. As a result, fans of the Game of Thrones TV series can identify some familiar aspects of the film in the accompanying music and symbols, enhancing their entertaining gaming session.
Other top branded slots include Rocky, Gladiator Road to Rome, The Black Knight, Sabaton, Wizard of Oz, Robocop, Rambo, Wonder Woman, Street Fighter 2, Jumanji, King Kong, and Jurassic Park.
These are the most common online casino slots hosted in most of the best UK online slots sites. Video slots are designed with diverse features that range from the number of pay lines and reels, symbols, bonus features, and themes. Popular video slots include Starburst, Tomb Raider slot machine, Gonzo’s Quest, Avalon 2, Wizard of Oz, Book of dead, and Thunderstruck 2.
Some slot games in most of the best online slots sites feature a jackpot prize. The jackpot prize could be a fixed prize amount or a progressive jackpot where the prize amount keeps rising as more players keep playing the game. A good example is the popular Mega Moolah, a progressive jackpot where the prize keeps rising and can grow up to millions of pounds.
These are simple slots that resemble the early slot machine games. They can be found on most of the best online slots sites. Classic slots have simple features and a few bonus features, and most are designed with 3 reels and a few pay lines instead of 5 reels found in many video slots.
Classic slots are also designed with familiar symbols such as bells, bars, and fruit symbols. Popular classic slots include Mega Joker, Jackpot 6000, Break Da Bank, and Triple Diamond.
These are new slots that operate on a unique pay mechanism. Each spin can turn up a random number of symbols on the reels, resulting in thousands of ways to win instead of the usual pay lines.
Many Megaways feature a maximum of 117,649 ways to win. Megaways slots may also feature more than 5 reels, in some cases bearing as many as 76 or 7 reels.
They also pay when you match symbols in adjacent reels, unlike the usual slots that usually pay from left to right. Popular Megaways include Bonanza, White Rabbit, Jammin Jars, and Gonzo’s Quest Megaways.
You can play Megaways slots at Big Time Gaming slot sites UK such as Play Ojo, 888 Casino, Betfair, and Leo Vegas casino.
Before playing online slots at the best slot sites UK, it is advisable to understand the main features and how to play slot games.
Slot games have different symbols that determine how much you win in any spin. The different symbols bear different values, and your winnings are determined by how many symbols you match on the pay lines. Most slots award you a win when you match 3 or more symbols across the pay lines.
These are the lines where winning symbols line up. They are used to determine whether you score a win or not.
Slot machines may have fixed or variable paylines, which you can bet on. In fixed pay lines, you have to wager on all the paylines, while in variable paylines, you have a choice on the number of pay lines to activate or bet on.
When playing slot games, you may manually spin the reels one after the other or use the Autoplay feature if it is provided.
The Autoplay button operates by spinning the reels automatically up to the specific number of spins you have chosen. You can choose from 10, 50, or 100 automatic spins, saving you time instead of clicking on the spin button.
The best online slots have one or more bonus features that help to boost your overall payout in the game. Some of the primary bonus features are borne out of special symbols that include:
These are special symbols that can substitute regular symbols to help in completing winning combinations. For instance, if landing 3 matching symbols results in a win, and you land 2 matching symbols and a wild symbol, you can get a pay-out if the wild substitutes a symbol to the required matching symbol.
In most slots, wilds also have higher values than the regular symbols, and you stand to win a higher payout if you land many wilds on a spin. Wilds could be stacked; in which case they are clustered as 2 or more symbols.
These are special symbols that are usually the key to activating a bonus round. The scatter symbols pay from any position on the reels.
Scatter symbols are also important in activating bonus features. When you land 3 or more scatter symbols anywhere on the reels, you could be granted free spins
Some of the best slots UK have jackpot features attached to them. The jackpot amount could be a fixed prize that you can win when you land a combination of specific symbols. It could also be won when you complete a certain feat in the slot game.
Some slots feature a mini, minor, major, and grand jackpot prize.
In progressive jackpot slots, the prize keeps rising as a certain percentage of the bets placed on the game are pooled together and added to the prize. This can be found in popular slot games such as Mega Moolah and Divine Fortune.
Some slots have a multiplier feature that is attained when you land some special symbol combinations.
The multiplier might be fixed, or it might cumulatively increase as you hit more special combinations. The multiplier increases your winnings by multiplying the payout that you win in the spin or round.
Multipliers might be standalone, such as X5. In such a case, if you win £100, with a multiplier of X5, you end up with a payout of (100×5) or £500. They might also be a combination where getting a multiplier of X5 and X2 gets you a total multiplier of x7 on your pay-outs.
Some of the best UK slots give you a chance to gamble your pay-out to increase your overall win. If you make the correct prediction, the gamble feature may award you double or quadruple(x2 or x4) of your winnings.
However, you should note that it is risky, and you might end up losing all your prize if you make the wrong prediction. On the bright side, though, if you get a payout of, say, £500 and gamble correctly, you could end up with a total payout of (500×4) £2000.
The volatility of an online slot determines the frequency of winning in the game and the maximum amount that you can win from the slot game. For instance, slots with high volatility tend to get you huge winnings, but the frequency of hitting the huge winnings is low.
You should also be ready to endure long periods of dry spins before you can hit the huge wins.
On the other hand, slots with low volatility tend to hit winnings more often, but the payouts are of lower amounts. Your choice of either low or highly volatile slots will determine how much you can win when you play the slot game at the best online slots site. Fortunately, the best slot sites UK host slots with all types of variance to suit your gaming needs.
The online casino industry is home to thousands of best UK slots with varying features. Therefore, it can be a bit overwhelming for a new player who is joining online casino gaming to identify the best slots to play.
From Mermaids Millions slots, Thunderstruck, Life of Brian slot, Irish Eyes, Starburst, or Tomb Raider slot, to a million other slots machines, it can be hard to settle on one, especially if you don’t have any information about them. Below are some of the best UK online slots you can start with when you log in to the best UK slot sites.
The popular Mega Moolah is a progressive jackpot slot developed by Microgaming. The slot game, an African jungle-themed game, features a Mega jackpot, Major jackpot, Minor and mini jackpot, an RTP of 88.12 %, and low volatility. Its popularity stems from its huge jackpot wins, taking it to the Guinness Book of World records for the gigantic jackpots, which could rise to more than 18 million pounds.
It is Big Time Gaming's most popular slot game and among the first of the unique megaways slots. The slot game features 6 reels and the megaways pay mechanism where the maximum way to win for the game is 117, 649.

Wagering requirements affect the amount of bonus you end up with, how much you spend to convert the bonus to cashable amounts, and the duration of time it takes you to convert your bonus to a credit balance.
The higher the wagering requirements, the harder it becomes to wager the bonus and convert it to cash.
For instance, wagering requirements of 50 times on a bonus of £100 means that you must wager £5000 on games before you can enjoy your bonus as a credit balance. On the other hand, wagering requirements of 20 times on the same bonus of £100 means that you only need £2000 to convert your bonus to a withdrawable bonus.
