A video slot, or simply, a slot, is a type of casino game, where it is possible to play for money expecting some return (including a jackpot). The history of slots runs over 100 years. First, they were gambling machines where the spinning of reels was initiated by pushing a lever, which was then replaced by a button (to make it easier and more convenient for all audiences to play). Modern video slots played on the Internet are operated with a mouse or finger and they have a number of settings, themes, and possibilities. They also widely differ by graphics, manufacturers, year of issuing on the market, and simplicity/intricacy.

The basic gaming process is as such: a person bets money to spin the reel and if some winning combination occurs, he or she is rewarded with won money, the volume of which depends on the strength of the combination. Also, if a slot has more than 1 payline, then the chances of winning are multiplied by this number but also are the bets. The market is captured today by slots having 3 and 5 reels. It is possible to meet others (like having 4 or 6 reels) but their number is so humble that it’s nearly indistinguishable from the absence.

The basic knowledge you have to know about slots is as follows.

There are many symbols on the screen. Some of them are regular and form winning combinations, while some are special, and they’re called ‘wild’, ‘scatter’, and ‘multiplier’.

Wild is a player’s best friend, as it can substitute all other symbols but scatters and thus, improves the chances of winning. It can occur in any line and reel.

Scatter is a reward symbol, which can give some bonus, start a bonus game, or grant free spins (FSs) – that’ll depend on the conditions of each particular slot.

Multiplier allows increasing current winning by some specific number, let’s say, by 10. It is possible to receive a combination of multipliers, which will go up, bringing huge winnings to a gamer.

Also, there can be combinations of those mentioned, which, depending on the game, can result in significant bonuses and winnings.

There is also a possibility to make settings in slots (especially modern ones):

  • quality of graphics (for stronger/weaker computing devices of users) and sound level (to adjust comfort)
  • the size of a bet (from min to max) with up/down arrows, as well as through the usage of a button ‘Max Bet’ that’s usually embedded in every slot’s interface
  • played paylines (in slots offering more than 1 payline, a gambler can choose a number of paylines to bet for each spin)
  • quick play (simply spin the reel with default settings – to avoid thinking too much about the gaming adjustments)
  • autoplay (allows defining the number of reel spins, which the game will initiate automatically based on additional conditions). Most modern games offer such user-defined conditions: the number of spins to undertake & when to stop (like reaching the level of balance, winning, bonus round start), how long in the time will this autoplay act.


Quick start and Autoplay features save time and allow to simply get plunged into the game without thinking and extra actions like hitting the start button over and over.

There are other features of slots like available special symbols, the RTP level, volatility, participation in the bonus programs of the casino (all slots will have from 0% to 100% contribution to site-specific wagers), and taking part in progressive jackpots. As for the latter, progressive jackpots often are the utmost attractions of gamblers, who desire to become rich thanks to winning them. As a rule, they are from tens of thousands of Euros to millions of Euros, and they’re collected from 1 slot or several slots, one or more than 1 best slots sites.

What is Slots Site?

A slot site is the website of an online casino, where a punter decides to play. The design and interface of every such website (including the newest slot sites) allow a player to fulfill basic actions required to play slots in the best slots sites UK:

  • Register (because anonymous gambling for money isn’t allowed in most jurisdictions of the world, the same as anonymous withdrawal, whilst anonymous deposits are pretty frequently allowed in small sums even on the best slots sites)
  • Pick a slot in one of the newest slot sites based on likable criteria
  • Deposit money to a gaming account to form a bankroll
  • Receive bonuses and extras from the best slots sites UK and from slots themselves.

Best Online Casino Slots

Best online slots slots

There exist thousands of various online slot sites containing games of over a hundred gaming manufacturers. It is hard to find an economically advanced country with at least a mid IT level of its development and infrastructure, where there would not be at least 1 gaming manufacturer operating for the best slots websites. Some are as old as 80+ years, operating since the 1940s (first, catering to land-based casinos, then adding online games to their activity pool).

While we’re talking about slot software providers for the best online casino slots in the next chapter, here we’d like to highlight some great video slots having 3 or 5 reels. We’ve arranged them by the Return-To-Player (RTP) rate, starting with the best (that have over 99% RTP) and moving further down to 97+%. What you should know – anything above 96% RTP is your friend. Oh, by the way – we took information about RTP from our sources but it is a possibility that our readers find another information on the Internet. If there are any discrepancies found, please inform us about them so we can make the corresponding changes after the rigorous checks of each particular case.

  1. Goblin’s Cave (99.32% RTP). It’s allowed to bet just 1 cent for 1 spin on the best online slot sites, allowing a maximum bet of 75 Euros per spin. It’s a PlayTech’s 3-reel game with 3 paylines and x150 max jackpot. It does not have multiplying symbols, free spins, or progressive jackpots but it does have wild symbols, bonus game, scatters, and the option of autoplay. The theme of the slot is an old goblin that spins the reels of the slot allowing a player to take some from his possessions (gold, precious stones, and chests) or takes money from luckless gamblers.
  2. Ocean Princess (99.07%). It is another slot by Playtech with 3 reels and only 1 payline, playable on the best online slot websites. The jackpot is x1,000. It only has a wild symbol and autoplay from the rest of the gaming features, which aren’t present.
  3. Ugga Bugga (99.07%). The release of this slot was in 2013; it’s made by Playtech. It is possible to achieve an x1,000 jackpot on any top slot site. It does not offer free spins and has low volatility. Its 3 reels give 10 paylines with the betting volumes from 0.01 Euro per 1 reel to huge 250 Euros per 1 spin. The theme: aborigines and symbols of their lives: colorful masks, drums, sheds, exotic food, and things used for rituals. The drum-based music makes a player feel like being on some exotic island on a dream-like vacation.
  4. Mega Joker (99.00%). This slot by NetEnt has 3 reels and 5 paylines on its 3*3 classic gaming field, offering progressive jackpot, high volatility, and a super-game mode. The year of release is 2011. The minimum bet is 0.1, max is 10.
  5. Jackpot 6000 (98.90%). The slot of 2014 was released by NetEnt. It has 3 reels, 5 fixed paylines, and it is themed as a vintage game with joker & fruits having bonus rounds. It does not offer free spins, progressive jackpot, or multiplying symbols, as well as there is no Autoplay button (but there is a quick spin). Bets per 1 spin are from 0.1 to 10 Euros.
  6. Pikotaros Pineapple Pen (98.41%). The manufacturer is Ganapati company. There are 5 reels with 40 paylines. The game offers wild symbols, scatters, free spins, and bonus rounds. The minimum bet is 0.4 per spin, the max is 120 Euros. This is a simple-graphic video slot, where fruits, veggies, and simple items like a shoe, a pen, or sunglasses make the main sequence of gaming symbols.
  7. The Legend of Big Foot (98.00% RTP). A slot with the theme of the hairy creature by SG Gaming. Offers nice graphics and many options of free spins.
  8. Blood Suckers (98.00%). Obviously, no other theme but the vampire one would be suitable for this video game. This low-volatility slot has 5 reels and 25 paylines. The max jackpot is x1,014 of the bet. It was developed by NetEnt gaming studio. It is possible to bet from 0.25 to 50 Euros. Amongst the bonus features are wilds, multipliers, scatters, and free spins. Depending on the number of scatters a gamer sees on the screen, the bet increases as such: 2 scatters = 2 times; 3 scatters = 4 times (+ 10 FSs); 4 scatters = x25 (+10 FSs); and 5 scatters = x100 (+10 FSs).
  9. Starmania (97.87%). The provider of this 5-reel 3-row slot is NextGen Gaming. The number of paylines is 10. Possible bets range from 0.1 to 20 Euros per 1 spin. It is possible to win a thousand times of the bet at most on any of the top 10 slot sites. The Autospin button works as usual – allowing up to 100 automatic spins (player-established conditions like stop when a bonus round starts or when a huge win occurs also apply). The visual design of the slot allows feeling the simplicity and airiness, not providing any boxed-like symbols. Here, they rather occur in the air on the symbolic cosmic background. The symbols are represented by order-shaped stars and many-edge precious stones, where wild and scatter symbols appear on the background like a disco of the ‘80s. In the free game, it is possible to receive up to 10 free spins. The year of release is 2015.
  10. Kings of Chicago (97.80%). This 5-reel 5-payline video slot looks like a classic one. Major symbols on its playground are cards of different values (from 4 to Ace). The company-manufacturer is NetEnt. What’s different about this slot is a nice win: 10,000 times of the bet. Also, rather than matching individual symbols as in the vastness of other slots, the goal here is to collect poker hands – with the rules of poker applied completely. So, the winning combinations are all types of flush, all types of the straight, full house, and 3/4/5 of a kind. So, here, a gamer has to be acquainted with poker rules. It’s possible to bet from 0.10 to 50 Euros per 1 spin. The slot does not provide a bonus game or progressive jackpot but it does provide wild and scatter symbols, multiplier, the option of autoplay, and free spins.
  11. Golden Tour (97.71%). This slot was developed by Playtech. It has 5 reels and the same number of paylines. The max winning is x2,000. It does not offer free spins, progressive jackpot, or multipliers but it has bonus rounds, wilds, scatters, and autoplay. The min coin size to bet is 0.01, the max is 5. The theme of it is golf and playing it.
  12. Devil’s Delight (97.60%). Another slot by NetEnt. The theme is based on 7 commonly known deadly sins. If you’ve forgotten them, here is a quick reminder: sloth, gluttony, lust, envy, wrath, greed, and pride. Basically, a set of standards things, strivings, and wishes, which define the everyday life and the behavior of every living person on Earth in the 21st Despite an eerie topic, the visual design of the slot is actually fun: winged hearts, attractive she-devil, the confused Reaper, un-scary tombstone from graveyards, various smaller-range devils, pentagrams, and so on. The game was launched in 2013, offers 5 reels with 20 selectable paylines, wild symbols, scatters, and multipliers, as well as one of the hugest jackpots we’ve encountered: x200,000 of the bet. It is possible to receive free spins, bonus rounds, and expanding wilds should they occur at some specific places. The bet per 1 spin is from 0.20 to 40 Euros.
  13. T-Rex (97.50%). The slot was made by Real Time Gaming. It has 5 reels, 25 paylines, offers free spins, scatter & wild symbols, autoplay, and a progressive jackpot. It does not have a bonus game or multiplier. The volatility is medium. The theme is prehistoric creatures looking like dinosaurs but they do not make up the entire gaming field. In addition to them, there are standard card-inspired symbols like 9, 10, J, Q, or A, amongst others, and various greenery and hatching eggs. The betting range is from 0.01 to 0.25 coins per payline.
  14. Green Light (97.50%). Another product of Real Time Gaming. It was released in 2011. It offers 5 reels, 3 lines, and 20 win lines. Medium volatility. The theme is car races (adrenaline, speed, and so on). The minimum bet is 0.2, the max is 100 Euros per spin. All gaming features but a bonus game are available: progressive jackpot, wilds, scatters, multipliers, autoplay, and FSs.
  15. Enchanted Garden (97.50%). This Realtime Gaming slot was launched in 2011. The features are as follows: 5 reels, 20 paylines. All standard gaming features are included. The volatility is low; the bets are from 0.01 to 0.25 per line per spin. The theme is soothing and resembles a shaded forest on a good summer day – not too hot, not too cold, just right to watch as various symbols appear on the screen: butterflies, precious stones, card symbols, wilds & scatters. It feels like a magic forest fairy is watching at a player from behind the trees.
  16. Crystal Waters (97.50%). This video slot dives a gamer into crystal deep waters of the ocean, where one finds items like sea creatures (fish, crabs & shells), sea-surface yachts, and supporting elements like card values. This RTG-manufactured progressive slot has 5 reels representing 5 paylines, with the bets ranging from 0.01 to 0.25 per line per spin. All standard gaming features but a bonus game are present here.
  17. Coyote Cash (97.50%). This RTG slot has absolutely the same gaming features as the previous position on this list. What differs it from the previous is the graphic – it is a cowboy-themed game, with a classic American desert with cactuses in the background. In addition to regular card items amongst the symbols, the gambler will meet a bus, a cash sack, a snake, bones of cattle, and others.
  18. Mermaid Queen (97.50%). This slot is manufactured by Barcrest company. It has high volatility, 5 reels, 3 lines, and 10 paylines, the minimum bet is just 0.10 but the max is 500 Euros. The jackpot is x250,000. It features symbols of wild, scatter, multiplier, has free spins, and a bonus game. The theme of the slot is nautical but instead of an ‘under-the-sea’ background, there is an old ship made of wood. The game corresponds to pretty much standard expectations in the visual design of its symbols: cards, pretty/handsome people, jewels, wooden ships, treasure map… It is too elegant and too polished to be a snapshot of real life.
  19. Simsalabim (97.50%). For those who desire pure magic, similar to the one shown on the stage, it might be a good idea to play this slot. All popular attributes of magic tricks are here: wand, cards, magic chest, disappearing pigeon, rabbit, and others. The slot by NetEnt offers 25 paylines with 5 reels, takes bets from 0.01 to 0.5 per line per bet, and offers an x7,500 jackpot. It is not progressive but it has all other features of the slots: bonuses, special symbols, auto-plays, free spins, and multipliers. It has medium volatility. The year of release is 2011.
  20. Couch Potato (97.43% RTP). This is one of the most classical slots on the market, as its design has 7’s, Bar’s, and all old symbols humanity has seen on the screens of one-armed bandits for over a century. The manufacturing company is Microgaming. The number of reels is 3, and there is only 1 payline. As for special symbols, there are only two: wild and multiplier. The minimal bet is 0.25, max is 15. There’s no jackpot, no free spins, and the available bonus is just 200 Euros. The date of release is 2014.

Slots Software Providers

Today, there are over a hundred gaming providers operating all over the world. Not each is reliable, as well as not everyone obtains a trustful license. Through the years, some ceased to operate but their games are still playable. Some are newcomers on the market, having released just a few or a dozen games. Also, there are providers, which operate 20+ years having hundreds of successful games in their portfolio. Let’s review only those companies, which are considered reliable today & playing the games of which brings unbiased fun.

Microgaming. The company works since 1994 and has managed to create 340+ games (including slots) up to now. It is considered the most well-known and the most reliable company on the market.

Novomatic. It works since 1980 and as of the moment, it is the main rival of Microgaming. The number of games is comparable: 330+.

Playtech operates since 1999 and has nearly 200 games. The company is known for its amazingly high-quality graphics in games and the smoothness of their work.

NetEnt started its work in 1996 and has 150+ games in the portfolio.

IGT. 120+ games. Works since 1990.

NextGen Gaming works since 1999 and has made about 110 games for the period.

EGT. 100+ games; works since 2002. Originated in Bulgaria.

Play’n GO. 1997. Nearly 100 games.

Booming Games. A market freshman with slightly below 100 games.

Aristocrat. It was born in 1953 as a caterer to land-based gambling venues. Today it offers 75 online games.

Barcrest Company dominated the market in the 1970s but was acquired by IGT in 1998. It has over 50 own games.

Endorphina only operates for several years and has released 44 games so far but it actively competes.

BigTimeGaming is another newcomer with 23 games so far but increasingly more online casinos include the company’s games in their catalogs.

Pragmatic Play works since 2015 and it’s not too active in making new games, having made only several dozen of them.

Other known names include such companies: Wazdan, Realtime Gaming, Amatic Industries, ThunderKick, Tom Horn, YGGDRASIL, Softbet, and Betsoft.


Playing any of the named will be fruitful and reliable. Yet, not only one must look at the slot itself – but there is also a casino on top of that. If the casino owners will lead a biased game, changing the gaming mechanics and chances, this won’t be good. Eventually, a casino is a sole responsible entity for the quality of games – as it can change games on its website without the knowledge of manufacturers, make it impossible or unfair for people to play there, including blockage of accounts with positive balances out of the blue. That’s especially what unlicensed casinos do. So before starting any gambling in any funhouse, make sure to rigorously read all pieces of feedback for this casino online on as many third-party websites as possible.

How to Play at Online Slot Sites

There is nothing simpler than playing an online slot. First of all, choose one of the casinos (from our list or by googling) based on their bonuses, feedback of other users, supported channels of financial flows, available games in their catalogs & general likability, which is only your personal impression.

Then register and start playing after depositing some real money. Not depositing is also possible but it won’t lead to winnings of real dough, at least, not a large one.

Should you win, decide on whether you’d like to withdraw money or use it as bankroll for further bets.

Once in a while, return to the casino to check for new bonuses, gifts, and games.

Slots Payment Methods

Payment methods of every modern casino are adjusted to the needs of gamblers. They most often include Visa and Mastercard bank cards, Neteller, Skrill, e-wallets, PayPal, maybe bitcoins, and bank account debit/credit possibilities. A certain list of channels shall be found in each casino, as everyone strives to establish their own rules. Also, these rules include min and max deposit and withdraw volumes per channel & per day/week/month.

When playing in a UK-registered casino (being a UK resident), it is possible to find at least several suitable channels, which provide the lowest transaction fees and better time of execution of payments.


Playing the best slots sites UK is fun. Their overwhelming part doesn’t require any specific knowledge to start playing. But the things also depend on gaming houses, which are direct providers – some of their rules may be inappropriate for you, or their bonuses may be too small. So, study the situation as a complex: casino + slot + payment channel + your preferences. The outcome of the combination is only up to you, as with the newest slot sites and the number of modern games, only the sky is the limit.
