Every one of the online slots sites on our list has been licensed and regulated by the UK Gambling Commission, which means that they are completely safe and legal to play at. However, there are a number of other factors we take into account, including the quality and the quantity of the slot games available, the amount of jackpot and progressive jackpots, the amount of mobile friendly slots as well as the best bonuses and promotions available for new players looking to sign up, and existing customers looking for value.
The Best Slot Sites Available in the United Kingdom
Because of the sheer number of sites out there offering quality online slots, competition is strong. So, in order to stand out from the others, online slot sites try to offer players something that other sites don't offer. Many try to get a player through the casino door by offering a hefty and generous welcome bonus with extra spins on top. Some offer players a 100% welcome bonus amount, some have a large number of free spins to try the site for free, and others offer free spins with no wagering requirement attached, so you get whatever you win. This means that because there are so many online slot sites, the only winner is the player. Slot players in the UK are now completely spoiled for choice. They can pick their new site based on the bonus offer, or it could be on other factors like progressive jackpot slots, generous terms and conditions, low wagering requirements, high return to player rates, quality of tournaments, free spins on offer or the variety of new titles and exclusive slots. You can choose your slot site based on what you are looking for.
Because of the competition, any player signing up is precious, so the best slot sites will not only offer new customers a generous welcome bonus amount when they make their first deposit. Most also offer a VIP or loyalty program to help keep the players once they have signed up. Generally, players can gain loyalty points by playing on slot games. The more you spin, the more you can win. Moreover, unlike other casino games, slot games normally contribute 100% to wagering requirements. Any slot player that knows what they are doing, understands that they can take advantage of the generosity of slot sites and will sign up with a number of top UK slot sites so that they can benefit from the strengths of a number of different sites.

This is a 3-payline game with a hold feature. However, it is the multi-spins gameplay and ability to hold symbols that make the game an excellent mix of luck and skill - and makes it one of the highest RTP online slots.

You can then choose which symbols you want to lock in and hold. Again, this adds an element of skill and takes the RTP up to over 99%.
- Mega Joker - RTP of 99.00%:This time it's a NetEnt game that takes third place.

Additionally, slot game features such as free spins, wilds, extra spins, bonus rounds, and multipliers can also have a huge impact on the slot game's maximum win. So, not only should you look at the game or slot site's RTP, but you should look at all other factors that could affect your winning potential.
There are slot sites always making inroads into the list and are increasing their payouts as time progresses, so it's always a good idea to check these out regularly as these can change from time to time.
Online Slot Sites With No Wagering Requirements
The very best slot sites are those that offer new players a welcome bonus or free spins and extra spins with no wagering requirements attached, although these online slot sites are very few and far between. So, they are well worth taking advantage of when you find them. Generally, you will find that these welcome bonus offers will be free spins rather than a specific deposit bonus amount. However, the number of free spins you get with no wagering requirements can vary greatly, from 10 free spins to 50 free spins or more. This depends on the slot site and can also depend on how much your first deposit is. Remember to check the bonus offer terms and conditions and validity as some may have other tough terms attached, including short expiry dates.
Often, the slot site in question will make these no wagering free spins available for set games only - very occasionally will players be able to use these free spins on the game of their choice. Remember, different slot sites have different terms attached.
The Best Slot Site for No Wagering Free Spins
Although there are a number of slot sites that offer no wagering free spins on sign up, such as Paddy Power, the one slot site that really stands out in this regard is PlayOJO as all of its free spins and extra spins bonuses come with no wagering requirements as standard.
PlayOJO - Welcome Bonus 50 Spins No Wagering Requirements
PlayOJO has a USP that sets it apart from all other online slot sites out there. It isn't a huge bonus amount, or hundreds of extra spins, it is the value of its offer - 50 free spins on sign up with no wagering. This isn't just it though. Every free spins and extra spins bonus offers all come with no wagering requirements, which is what makes it stand out. This slot site also has hundreds of excellent slot games and jackpot games, it offers its players unique loyalty rewards and has cashback offers on all games.
Terms and Conditions:Full T&Cs apply. 18+. First deposit only. 50 Free Spins on the Book of Dead slot. New players only. Min deposit £10. Excl. new players in N.I. Each Free Spin valued at 10p. No wagering requirements. OJO’s Rewards and Game Play policy applies. Must be used within set time period.
Best Slot Sites with Low Wagering Requirements
No all slot sites can offer no wagering requirement - and, indeed, not many do. Slot sites put wagering requirements into place because they need to control how much they pay out in bonus funds and bonus winnings. Slot sites can't simply give away cash. As such, even the best online slot sites attach wagering requirements to bonus funds and free spins. However, what we do expect from a good slot site is reasonable, preferably low wagering requirements.
If you are looking to enjoy playing slot sites, then you want to know that you have enough money in your account to play your favourite slot games. This can be aided by generous welcome bonuses and bonus offers. But these have to be worth your while or they can cost you more than you make. Before a player signs up for an online slot site and claims the offer it is vital to read the terms and conditions attached, especially the wagering requirements. Here are the best online slot sites for low wagering requirements attached to the bonus offer.
BetZest - £5 Completely Free Welcome Bonus
BetZest may not offer a huge amount in bonus funds, but the £5 that it does offer new players is completely free, which means there is no min deposit. Not only is it a no deposit welcome bonus but this is one of the slot sites with the lowest wagering requirements, set at just 15-times wagering.
Terms and Conditions: New customers offer. Geo Restrictions apply. 15x wagering requirements. Mobile verification required. Max Bous £5. Full Terms apply; 18+.
William Hill - No Deposit 50 Free Spins Offer
William Hill is well renowned for excellent offers and bonus amounts. One of William Hill's new player offer is No Deposit 50 bonus spins. Not only is this a no deposit offer, but with just 20-times wagering requirements, this is one of the lowest slot sites out there in regards to wagering requirement terms.
Terms and Conditions: New customers only. Opt in required. 1x per customer. Max 50 free spins with 20x wagering. Stake £10 stake & get 100 free spins on completion with 20x wagering. Selected slots only. Free spins expire 24 hours after issue. Eligibility rules, game, location, payment method and currency restrictions and terms and conditions apply
Mayfair Casino Slot Site - Up to 50 Free Spins
Mayfair Casino stands out from other slot sites because of the quality of its welcome offer for new players. New customers making their first deposit can enjoy up to 50 free spins on selected slot games with a min deposit of £10. There is an alternative welcome offer of up to £200 cashback with a min deposit of £50 - with a max bonus for the cashback offer £200. Compared to other slot sites, the terms are very fair, with just 20-times wagering requirements.
Terms and Conditions:T&C -New Customers Only. First Deposit only. Minimum Deposit Balance £10 for Spins. Minimum 10 and Maximum 50 bonus spins on selected slots only. 2x Conversion, 20x wagering. Max Free Sins winnings may apply. Min Deposit £50 for 10% cashback on 1st deposit based on slot net losses for 24 hours. Max Offer Cashback £200. Elk Gaming Slots excluded. T&Cs Apply.
Most of the slot sites that offer low wagering requirements for their welcome offer also come with low minimum first deposit amounts, which makes the offer perfect for a player looking to play the small stakes. This is really important to look at, as it is not unusual now to see huge welcome bonus offers - up to £500 at times, but coming with wagering requirements that can go up to 65-times to bonus amount. This means that if you take a 100% welcome offer up to £500, you need to deposit £500 to claim the full bonus. If your bonus funds come with a 65-times wagering requirement, then in order to withdraw the bonus and winnings, you will need to stake £32,500 in the set time limit. This is a huge amount of betting. However, some even stipulate 65-times bonus + deposit, which would double that amount to £65,000! We would recommend that you favour bonuses with wagering requirements of 40-times or less. However, the lower the better.
Best Online Slot Sites For Tournaments
One of the most exciting things for dedicated slot players is the opportunity to enjoy slots tournaments. The very best online slots sites will offer players gameplay involving cash drops, missions and tournaments. Tournaments are very simple and they really encourage players to keep playing on the slot site. A player simply needs to play on a specific slot game but instead of accumulating real money, they will build up points. Tournaments can vary from slot site to slot site, but the general rule is that players are competing against each other, trying to win the most points before the slots tournament comes to an end. However, generally, free spins winnings will not count on the leaderboard.
Generally, the best online casino and online slots sites will not charge a player to enter the tournament, but on occasions, a slot site will ask for an entry fee. In this case, a player would normally then get free credits to play on the slot game. Not all online casino sites offer slot tournaments, but here are some that do.
Unibet - Deposit £10 Get a £40 Casino Bonus
One of the best online slot sites for tournaments is Unibet, which offers players a number of tournaments with real money, cash prizes, tech prizes and even holidays for the winners. Examples of this include Unibet's £100,000 February Frenzy. In order to take advantage of the tournaments available, players need to sign up for the site. On registration, the new player offer is deposit £10 get a £40 casino bonus.
Terms and Conditions: 18+ begambleaware.org. New customers only. Min deposit £10. Money back as casino bonus. Bonus must be used within 30 days. Wagering requirements apply. Further T&Cs apply.
Most of the online slot sites also offer smaller prizes to players as the slots tournaments progresses, this could be additional bonus funds to play on the games, free spins and extra spins - and then a huge prize pool with a big lump sum for the slots tournament winner. Often the online slot site will have a set prize pool. However, sometimes it might work the same as jackpot slots where it grows depending on the number of online slot players that join in and start playing. As is the case with all online slots, where you end up on the leaderboard is often about luck. However, there are ways to increase your chance of winning the online slots. It's better to make the maximum bet, get the spins going as quickly as possible and try to get on the slot games free spins and bonus features.
