Guide to Online Slot Sites in the UK 2024
This site is packed with the information you need on the best online slots. There are thousands to choose from so we have made your task easy by creating a list of the best slots to play, bonus offers and tips on how to play. Our guide covers high/low volatility slots, progressive jackpot slots, themed slots, classics and more. This page will cover all your questions and help you make a winning start.
Are Online Slots Rigged?
Any online slot housed inside a regulated online casino will be fair. Software providers at our recommended casinos are trustworthy because game manufacturers for licensed jurisdictions must have their Random Number Generator (RNG) certified by an independent agency. It is important to note that software providers create and control the games, casinos simply host them but are unable to influence how they work. Therefore, winning or losing at slots comes down to variance.
Slot providers only thrive if they are legitimate and fair, otherwise, people would simply stop playing. It is not in their long-term interests to rig slots. The UK Gambling Commission (UKGC) has strict licensing conditions regarding the setup of online slots. All of this means you can be fully confident that any slots we recommend have been tested, are fair and come from a trustworthy source.
Advantages of Online Slots Compared to Land Based Slots
Land-based casinos were the original home for classic reel slot machines, but we think online casinos have some pretty clear advantages when it comes to playing slots. For starters, you can play online from the comfort of your own home on your preferred device. You can do this anytime you want from any location. Online access also allows for a much larger player base and this means that progressive jackpots are much bigger online. Another key factor is game variety, you simply have a lot more choice online.
Online casinos are now home to literally thousands of online slots and you can search by software provider, theme, jackpot and more. You also enjoy great visuals, 3-D effects and razor-sharp sound effects. There is also the issue of bonuses; these are much more varied with online casinos and allow you to take advantage of free spins offers, specific game promotions and fun seasonal promotions. These bonuses are generally good value, always attractive and they give you more opportunities to play and win. The best online slots typically have much higher RTP's than land-based games so you are likely to win more money when your symbols match.
Advantages of Online Slots Compared to Other Casino Games
There are several advantages to playing slots online compared to other casino games - there are few games that are more accessible to newbies than slots for the following reasons:
- Low minimum betting limits.
- Large jackpots sometimes topping £1 million.
- No real skill required, just spin!
- Huge game variety and themed options
- Multiple ways to win due to bonus rounds
- Free spin promotions
Slots are also a huge amount of fun! The best slot games can keep you entertained for hours.
How to Win Online Slots
The best online slots in the UK are games that are fun and easy to play. Your appetite for risk and spending will play a role in how you approach games with an eye to winning. It always makes sense to manage your bankroll and select games based on your style of play and personal interests. If you like to play for a long time, then pick an entertaining low bet size and low volatility/variance game. If you’re not afraid of a little risk, then you can choose to play high variance/volatility and high limit slots in simple formats (3-reel classics etc) with a small number of paylines.
Take advantage of bonus offers to boost your spin time and winning chances. Games that display ‘all ways to win’ or ‘243 way to win’ have high hit ratios and tend to churn out more winners as do games with lots of paylines. It is best to avoid jackpot games as the overall RTP for normal spins on these games tends to be lower due to the jackpot contribution. Whatever option you go for, remember to play consistent and manage your bankroll properly. Discipline is important, no matter what casino game you are playing.
Do Online Slots Pay Real Money?
Yes, they do. Real money payouts are a common feature and this is ultimately why people play real money slots. The wins can be huge too, you can walk away with millions in fact- just like the lucky winner who won the Mega Moolah jackpot in September 2018 and took home a staggering 18.9 million euro!
How Do Casino Slots Work?
Online slot machines look similar the physical machines and most of the time, it is a simple matter of spinning the reels and seeing if you’re luck is in. One thing you will hear about at all of the best online slots is the random number generator (RNG). This is the software used to auto-generate the sequence of numbers that determines the position of the reels. It is the mechanic that makes online slots work while ensuring that all spins are fair and random. RNGs give everyone the same chance of winning, regardless of when they spin because they always produce random and different numbers every time you click the spin button.
It is important to note that the software providers create the games and the online casino is a platform that hosts these games. The software providers supply these games to thousands of online casinos around the world.
Progressive jackpot slot games work a little differently: they are all linked across machines, games, websites, and casinos - this combination is what leads to those massive total payouts. As soon as there is a winner, the game is reset and the jackpot begins to build up again.
Best Online Slots with the Highest RTP
Return to Player (RTP) is the percentage of all the wagered money an online slots game will pay back to players over time. For example, if you make a hundred £1 bets on a machine which has an RTP of 90%, you would expect to get back about £90 in wins. It’s a key statistic that many players look out for but should not be your ultimate indicator of whether a slot game is worthwhile or not. A high RTP on a low variance game will result in regular small wins but not many big wins. This may suit if you tend to spend long periods playing slots but will not suit if you are hunting down a big win game. For this, you need a combination of high RTP and high variance. Below are some slots with the highest RTP:
- Mega Joker: 99%
- Chess Mate: 98.7%
- Cinema Classic: 98.5%
- Lucky mermaid: 98.5%
- Ways of Fortune: 98.12%
Slots Betting Limits
Slots betting limits will vary depending on the game and online casino. However, every online slots game will have a minimum bet and a maximum bet. This will be a cash amount (i.e. GBP) or a coin amount (a credit that's worth a certain amount). In general, the smallest coin (or cash) amount you'll be able to stake online is £0.01. At the majority of online casinos, the upper spin limit sits between £200-£400 for new or standard players. VIP players who have been long-time customers often get rewarded with higher spin limits that can be customised around their favourite games.
How Many Paylines do Slots Typically Offer?
Pay lines are one of the key features of all slot games and they show you the ways you can win. Online slots have advanced a lot and they now feature a variety of different paylines. This means more chances for you to win but note, each payline requires an extra bet so 50 or more paylines means 50 or more individual bets. You will encounter the below 2 paylines a lot:
243 Ways to Win
- This format lets players win on a five-reel slot game for any three matching symbols from left to right. This low variance format proved to be a hit with casual players and can now be found on nearly all online slots. Basketball Star and The Dark Knight are examples of 243 ways to win slot games.
Win Both Ways
- This format breaks from the traditional left-to-right fashion and pays out based on both left-to-right and right-to-left combinations. Sometimes called “2 way pay” slots, they offer more chances to win and are very popular.
How Many Reels Do Slots Typically Offer?
The majority of games you'll find online will be 5-reel slots. However, many of the best slots sites also offer 3-reel slots. 5x reels and 3x rows is a very common format these days. In some instances, you can even find 6-reel slots, though the sixth reel is often a bonus feature that's only unlocked at specific times. Some classic 3-reel slot games are Double Diamond and Super Times Pay while examples of 5-reel games would be Starburst and Cleopatra. Sometimes you get niche slots with unique reel features. An example is the Spartacus Gladiator of Rome online slot which has 2 sets of reels, a 5x4 and a larger 5x12 set of reels.
Reading an Online Slot Payout Table
Modern online slots offer you a variety of ways to win and the payout table shows information on how the slot will pay out its winnings based on symbols, bonus rounds and other possible winning combinations. In general, each symbol will be shown in its own box and the payouts for three, four and five matches will be shown to the left. Some online slots will display the actual cash amount (e.g. three symbols = £2) while others will show a multiplier. If you see a multiplier (i.e. three symbols = 3X), you simply multiply your single line stake by the number shown to calculate your potential winnings.
The payout table is important as it can help you decide which slot you want to play. It will tell you which symbols are high and low paying, which are Scatters, Wilds etc and it may also tell you how many free spins you can get. Some games will have minimum betting requirements, and these will be displayed here. Here is also where you learn how to trigger a bonus as well as finding out how many spins are required for the bigger jackpots. This is also the place where RTP info is stored so paying attention to the payout table makes sense.
