Online Slots

Online slots are by the far the most popular option for players at online casino to enjoy. The reasons for this are plentiful. They are the most straightforward to play, they come in all different shapes and sizes with different themes and gameplay and cater to all players regardless of budget or skill.

With so many free sots available though, the issue is finding the right ones for you. This is where this page comes in, as on it you will find everything you need to know about the newest and best slots on the market via reviews, as well as how to get yourself some great bonuses to use on them too.

Slots Online at JohnSlots

Our site is the ideal place to find yourself a new slot game to play, as our team of slot experts spend hours researching and playing the newest and most loved slots to ensure that we deliver to you the best ones on the market.

We have countless slots on our website already, which you can browse through already and search for the perfect slot for you. Plus, loads more of the most state of the art, recently released slots added to our catalogue each week, so you can always find the hot slots on the market to play.

But, how do we evaluate them? Well, through the following criteria:

  • RTP – The return to play percentage is the amount the slot, in theory, will pay back to the player on their investment into the game. It is ranked as a percentage with around 96% being the industry average. Thus, if a casino has lower than that, we will pull it up as an issue, while if it has higher than that, then we praise it.
  • Variance – This works alongside the RTP but is different as it determines the size of the payout a player receives over time. A high variance slot will pay out less regularly, but when it does, it pays out a substantial sum. While a low variance slot will pay out often but in smaller amounts. What is good for a player is more down to personal preference than the RTP is. However, we will keep you informed about how it fits alongside the RTP so you can decide if it suits your needs.
  • Reel Layout – Slot games come in all different sizes and gone are the days of the 3×3 format. There can sometimes be as many as 9 reels nowadays and different players prefer playing different numbers of reels. We will tell you how many reels and rows can be found on the game, as well as letting you know if they have elements like “shifting reels” or anything else that might be worth knowing about the reel layout.
  • Special Features – One of the biggest shifts that has happened because of the rise of online slots is new additional gameplay features, which alter the way the game pays out. There may be exploding symbols, slots that pay out in symbols clusters, or anything else that makes the game unique, whatever the case may be, if a slot game has a special feature, you will know about it.
  • Jackpot – Winning big is what is on every player’s mind. This is why you need to know what exactly the biggest prize on offer is, i.e. the jackpot. There are various types of jackpots too, so we will tell you which one it has. While if there is no jackpot, then we work out the maximum win on offer to you on that slot.
  • Bonus Features – Special features are great, but the opportunity to move away from the base game and enjoy something a bit different is always nice too. Which is why we check what sort of bonus features are on offer. These can be very diverse, and some may fit into the theme somehow or offer a completely new dynamic. Some may have numerous types available; some may have none. Whatever the case, we will let you know what it is.
  • Mobile Version – In this day and age, playing on the go is a quintessential part of the slot game experience. As such, it has to come into consideration when we evaluate a slot. Nearly all slots have this available as a given, however, some slots may not, so we always double check.
  • Graphics and Sound – We like to know what sort of aesthetics the game has on offer. Does it offer high definition graphics, or does it have a more jovial and cartoonish theme? Does it have intense music to immerse you into the gameplay, or is it just the conventional sound of slots? Perhaps it is in 3D? Some game designers put a lot of effort into the design aspects, but others can be a bit lacklustre. As such, we like to make sure that the look and sound of the game are suitable for players as often if they aren’t, then other aspects of the game aren’t either.
  • Bonuses and Free Spins – Finally, we want to know if players can enjoy some free gameplay on the slot, courtesy of the casino. Hence, why we check what sort of bonus and free spin deals are available to the player that can be used on the slot game. This not only gives the opportunity to try the game out for free, but they can also accumulate some funds too.

Play free slots and learn the game

Play free online slots and learn the game

One way to decide whether or not you should invest in a game is by playing free online slots. Nearly every UK casino you find online will have free slots to play for fun that you can enjoy with no card details and no deposit required.

Why are free slot games a great option? Well, several reasons, including:

  • Low On Bank Roll – If you are low on bankroll and don’t want to spend the last of your funds on a game you don’t know, playing free slots can help prevent this. You can play free slots for no deposit and see if you like it. If you don’t, then you haven’t wasted any cash, if you do, then go ahead a play for free money.
  • Practice Makes Perfect – Even though slot games are pretty straightforward, each is different in its gameplay. This means that starting a new slot can be tough at first. By practising for free, you don’t make any rookies mistakes on a game you would make as a beginner playing the slot for the first times. This allows you to rid yourself of any teething issues so that when you are ready to play for money, you are playing at the best of your ability.
  • Master Bonus Rounds – Similarly, if a game has a bonus round, then you should master this before you to start playing for real money, as a bonus rounds might be seldom triggered. With this in mind, if you start a game fresh, have no idea what to do when the round starts and then waste it, you might not get a chance to benefit it from it again. Mastering bonus rounds is essential to making the most of a slot game.
  • Do You Like It? – This sounds like a no brainer, but they also can help you decide whether or not you actually like a game. There are hundreds of games out there, and you can’t possibly try them all with real money. Playing for free can help you decide whether or not you actually like that game and if not, you can just play countless other free slots until you find one you do like.

One way to enjoy free slot games is with free spins and bonus spins. While if you are looking to learn how to get to grips with slots, then our how to play slots guide can help you before you find yourself some free games to play.

Play slots and win real money

Play slots online and win real money

Once you have mastered the free play mode, it is time to play slots online with real money. This is where the real fun comes in. The intensity of the gameplay and the benefits of playing are much higher when you play slots with real money as there is more to win and also, more risk. Both of which provide gameplay on a whole new level.

Once you get ready to play for real money, then the best way to kick things off is with a slot bonus. Slot bonuses are a lovely little perk of playing online that gives you more playtime for your coin. Nearly every online casino offers you one as an incentive to join or return to their casino for your online slot playing experience.

The most common are cash bonuses, whereby you can benefit by seeing your deposit increased by a percentage to give you that much more playing time for free in bonus cash. For example, a 100% bonus will double your money, so if you deposit £100, you will get another £100 in bonus cash. Allowing you to start playing with £200 on the site.

What is most lucrative for those who want to play slots with real money are free spins. These will essentially reward you for making a deposit with spins to use on selected games. Often these will be awarded on big name slots such as Starburst or Gonzo’s Quest. You can receive anywhere from 5 to well over 100 free spins, which is essentially a number of opportunities to play for free. Head over to our casino bonus page for more information about bonuses.

Once you start to play slot with real money, it is also important to aim big. This is why jackpot slots are a great option as these can really change your life. Mega Moolah is a good example, as it holds the world record for biggest ever online payout. Earlier this year, Mega Moolah also paid out a whopping €13,328,028.16, which obviously isn’t to be sniffed at either.

Best online slots from your Favourite Game providers

There are many online game providers on the market that offer online slots to UK players. However, for the best online slots in the UK, there are a handful of game developers that far exceed most others on the market.

While, of course, it is all down to a matter of preference, if you are looking for UK slots that are guaranteed to blow you away, then the below UK slots game providers are the ones you need to make your first stop.

NetEnt

NetEnt would be considered by most to be the best online slots UK game provider in the business. They have been in the slot game business for over 20 years and during that time they have brought to life some of the most loved games by UK slots players. Two of the best known and found at nearly all casinos are Starburst and Gonzo’s Quest, but the list could go on and on.

Today, they remain on top of their game when it comes to the online slots UK business, and their games continue to be ground-breaking and exciting. Over the last two years, they have brought more exciting concepts to life, such as Jumanji and Planet of the Apes, which came chock-full of great unique features and ground-breaking bonus games.

However, the company still shows no signs of slowing down though and should be at the top of the game for a long time to come.

Play N’ Go

Hot on the heels of NetEnt is Play N Go. Despite being ten years the junior of NetEnt, over the past 10 years or so they have taken the casino industry by storm with a whole host of great games.

Potentially, their most popular option is the Book of the Dead slot, but other well-known games include Mystery Joker, Leprechaun Goes to Hell and Moon Princess, but really, the list is endless.

Play N’ Go are a game provider who is constantly updating their slot game choices, with several dropping every single month. They have been dropping more unconventional slots of late and really pushing the boundaries.

For example, Queen’s Day Tilt which has 3×3 Grid Slot, which is constantly moving, and Wild Falls, which takes its name from the fact that Wild’s float down a virtual river and land on the reels for more wins.

Microgaming

Microgaming has been involved in the casino business since 1994, and in fact, claim to have opened the first-ever online casino. However, they have since directed their effort away from providing online casinos, and today, focus purely on games.

This is great news for online slots fans from the UK, as they have launched loads of awesome games since making the switch. What they are best known for is the Mega Moolah progressive jackpot slot though, which holds the record for the biggest ever online slot payout of £13,209,300.

However, other well-known games include the Halloween slot, Immortal Romance and the Playboy slot.

Microgaming is another game provider team who are always adding new games and when you take a look at their website, you will find a catalogue of new games for every single month of the year.

They are one slot provider who takes inspiration from pop-culture quite a lot. Two mentioned already are the Playboy slot and Halloween slot, while others include the Terminator slot, or The Love Island slot, based on the popular reality TV show.

Yggdrasil

Compared to the other 3 slot game providers mentioned so far, Yggdrasil is quite young to the game developing business, only opening their doors in 2013.

However, in a short period of time, they have become a household name in the online slots UK world. Bringing well-known games Vikings Go Bezerk, Vikings Go To Hell, Valley of the Gods and Spina Colada.

However, they are keeping up with some of the bigger name providers in the business, and there are always new slot games hitting the market designed by their team, with 2 or 3 new ones on offer every month.

Quickspin

Games by Quickspin are easily recognisable by their bright orange interface on which you operate the game. Perhaps this was done on purpose, as they too are fairly young in comparison to some other big known providers, opening their door in 2011.

However, since that time they have proven their worth by winning multiple awards over that time to cement themselves as a force to be reckoned with. Three of their best-known slots include Eastern Emeralds, Sticky Bandits and Spinions Beach Party.

However, there are a total of 50 games on offer, 45 which are available on mobile and 13 more due to be added in 2019.

If you are looking to places to play all these game providers games in the UK, then you are in luck, as they are available at most. However, to double-check, visit our UK casino page which will detail all there is to know.

New online slots releases

We have mentioned some of the best-known providers and their games, which you are able to find at most top online casinos already. However, every single month there are free and new online slots that hit the market.

Each with their own unique themes and dynamic gameplay that allow for new and fresh slot game experiences every single month. You can easily find 10-20 new slots on the market each month, from a whole array of different providers, sometimes even more. Most casinos will list these either right at the top of their slot page, or you can find them in a specific “new slots” section.

Naturally, at that rate of upload, not all of them are going to be ground-breaking, but that doesn’t mean you shouldn’t play new online slots. In fact, on the contrary, you should try as many as you can.

This is because new slots usually come with exciting new gameplay, with new bonus rounds and other special features for you to benefit from. This is due to the high level of competition which means slot providers must compete with one another, and the best way to do that is with unique and interesting themes and gameplay.

As such, you can benefit a lot more from new slots as opposed to old slots. Most of the time. With some being a lot better than others. This is why you should use our site to find new slots, read reviews about them and then play them for free before you commit.

It is just new slots that are always appearing on the market, but new slot sites too. As well as having all the newest games, they have more impressive bonuses and other services because they too must compete with a growing casino market. You can find these on our new casinos page. However, for news of both new slot sites and new online slots, check out our news page.

Why should you play online slots?

Online slots trump land-based casino slots in pretty much every aspect of how they work. Some of the top reasons include:

  • Convenience – Slot games give quick and easy gameplay. This is removed when you have to travel to a nearby casino or other location where they offer slot games. Online, this is no issue, as all you need is to log on to any online casino from the comfort of your own home and start playing.
  • Wide Selection – Online casinos have practically unlimited space. This means that they can hold many, many more online slots then a land-based venue could ever hold. This allows you to have much more options to pick from, each in a different style and with different gameplay for you to enjoy.
  • Play On The Go- Online mobile slots also give you the freedom to play as and when you want, giving you the option to play when you are out and about or even on the train somewhere via your mobile. Thus, meaning you never have to stop winning while you are on the go.
  • Bonus and Special Features – Online slots are loaded with bonuses and special features. This brings a whole new experience to the forefront of your playing experience. Rather than the conventional way to play, online slots provide so many more possibilities.
  • Bonuses and Free Spins – A land-based casino will hardly ever give you a freebie to play at their casino. Online slots do, which allows you to get more gameplay for your money and win more funds more often for less.

These are just the main perks of online slots, with loads more on offer to you that become prevalent over time as you play.

What types of online slots can you play?

As we have mentioned, the options for online slots are extensive and diverse, with players with different tastes also enjoying different styles of slots. This section offers a rundown of the most popular slots you will find online.

What types of online slots can you play?

Video slots

Video slots are what you will predominantly find at online casinos and essentially offer everything that we have so far mentioned. This means that they offer loads of different special features, varying paylines and unconventional reel formations.

As such, they flip what a slot machine should traditionally function as and just do so much more with the concept. Finding video slots online is easier enough, but you need to make sure you find a top-quality one which is where our site comes in.

3-reel slots

3-reel slots are the most compact slots games that are available, and so the gameplay unfolds on a smaller area. These may fit into what might be known as “classic slots”, which is the more basic version of slot games but are still enjoyable to some.

Here you generally have one payline and no bonus features, for more straightforward gameplay.

5-reel slots

5-reel slots are the more conventional style of slot games you find online. Most video slots will have 5-reels, but not all. 5-reel slots can cover a wide selection of different slot games and are the most commonly found slots available.

High limit slots

High limit slots are slots for the high rollers of you out there. They will let you play with bigger amounts, as well as win bigger amounts. High limit slots can vary but can see you spend £500 per spin.

As such, you should always be careful that you don’t accidentally get involved in one of these if you don’t have the funds to back it up.

Find the best slots to play online for you

There is no definitive answer to what is the best slot to play, with what are the best slots varying from player to player.

This is due to the variety on offer, as some players might like more bonus features, others a higher RTP or more outstanding design. Here you can find the best slots for various different popular varieties online.

Best RTP slots

Return To Player or RTP is an important part of any slot game as it details to you how much of the money you will put in, will come back to you. We have previously mentioned 96% is the average, but the best RTP slots will exceed this.

There are a few slots out there that have in the range of 98%, such as Blood Suckers and Uncharted Sea, but the highest you will find on the market is Mega Joker by NetEnt, which has a whopping 99% RTP and is the best slot to play if you are looking for this.

Best volatility slots

Choosing the best volatility slots isn’t exactly black and white as there are plenty that offers a similar rate of volatility. However, there are few recognisable games renowned for their high volatility, as well as their gameplay.

Two of these include NetEnt’s Dead or Alive and Play’n Go’s Book of the Dead.

Best Scatter Slots

There are countless games out there with scatter symbols, as such, the best is truly a matter of taste. You will find plenty of great ones on the market, so it is, in this case, better to shop around and find the best slot for you with scatters.

Some good examples that you could use as a jump-off point if you are new to the world of scatter slots are The Best of British Slots and Spinions.

Best jackpot slots

The best jackpot slots are clearly the ones with the most to offer in terms of wins. As such, a standout slot for this is Mega Moolah, who we have mentioned twice for some incredible payouts won by players in the past.

However, two other slots that have great progressive jackpots and can be found at loads of online casinos are Arabian Nights and the Hall of Gods.

Best fruit machines

Online fruit machines combine both the best of the old school and the new school, with the same classic symbols on show, but with more features that are available on video slots.

Deco Diamonds is a great option offering 1,000x their stake or the bright and fun Twin Spin Deluxe by NetEnt. However, these are nothing compared to Mystery Joker 6000, which offers 6000x the coin value and has an RTP that reaches as high as over 100%.

Best 3D slots

If you have ever played a Betsoft slot, then it would likely have had a 3D design. While others have ventured into this market, Betsoft is by the far the leader.

As such, for the best slot provider in this style, these are the guys you need to find, but other well-known providers have also thrown their hat into the ring as 3D slots have grown in popularity.

However, Betsoft ‘s Who Spun It and Good Girl, Bad Girl are great for design as well as RTP sitting a 97.79% apiece, and Gypsy Rose and At the Copa who have RTPs in the range of 97%

The best slot sites

Nearly every casino’s widest selection of games are slots. However, they vary greatly in the number on offer. Some slots sites will have a few hundred, but the best slots sites will have a few thousand casino slots for you to enjoy.

If you are looking for the most variety in casino slots as possible then it is the latter casinos you want to look for. The biggest selection belongs to the aptly named VideoSlots who have well-over 3,000 slots. However, SlotsMillion is always a great choice for variety too as they offer over 2,600 and growing.
