Basics of Online Slots

Even though slots may be one of the easiest games to play, it’s a good idea to know the game basics before you press the Spin button.

A slot game consists of horizontal rows and vertical columns. The vertical columns are known as the slot’s reels. The reels have the game’s symbols on them. The rows and the reels together form a slot’s layout. So, for example, a slot with a 3×3 grid layout will have 3 reels and 3 rows.

Slot Rows

Slot Reels

After you choose your bet size and hit the Spin button, you’ll set the reels spinning. Wins are awarded according to the combination of matching symbols landing across the reels (known as a slot’s Paylines).

Slot Payline

Traditional classic slots came with only 3 rows and 3 reels. They generally had between 1 and 7 paylines that paid out from left to right. However, in modern 5-reel video slots, the paylines need not necessarily be a straight horizontal line, but can be anything from horizontal, diagonal, or even a zigzag pattern.

The exact patterns you need for a win will differ from one slot to another. Therefore, you should familiarise yourself with the game’s rule before playing. Each slot’s paytable, features, and rules are displayed inside the game’s interface.

In simpler games, three of the same symbol on a payline award a win. Today’s video slots can have any number of paylines, from one to several hundreds! A punter is allowed to bet on multiple paylines to improve his winning chances.

Special Symbols

Apart from the basic symbols, online slots come with some special symbols, the most common ones being the Wild and the Scatter symbol.

These special symbols boost your winning odds.

The Wild symbol can replace any symbol on the reels, except the scatter symbol, and helps in forming winning combinations.

Today’s’ video slots have more variations of the Wild symbol to increase the winning odds, namely, the Sticky Wilds and the Expanding Wilds.

Similarly, Scatter symbols also help your winning chances, typically by opening up the game’s bonus rounds, offering free spins, etc. The rewards you unlock by landing scatter symbols in a single spin vary, and depend on the particular slot game you are playing.

Online Slots Return To Player (RTP)

One of the important things to look out for when playing real money online slots is the Return To Player (RTP), or payout percentage of the game.

RTP values are expressed as a percentage of the total wagered money on a slot to the total amount of payouts awarded by that game. The RTP value of each slot is calculated over hundreds of thousands of spins, and over a long period of time.

As an example, for a slot having an RTP value of 96%, for every £100 wagered, the slot machine will return an average of £96 in the long run.

Why RTP Matters

The RTP essentially indicates the house edge in a slot. The higher the RTP of a game, the better chances you have of winning. While players will look to play games with the highest RTPs to gain more winning chances, the casinos benefit with lower RTP games.

The RTP value of every slot is preset and fixed by the game's developer. However, the twist is, that some developers allow online casinos to change the RTPs of their games to some extent. It follows that a slot may or may not be having the same RTP value across different slot sites.

Online slots usually have much higher RTPs (90%-97%) than those offered in brick-and-mortar casinos.

To help players make informed decisions, the UKGC has made it mandatory for all UK-licensed slot sites to publish every game’s RTP. You can check a slot’s RTP in the game’s interface itself.

Of course, the RTP is not the only thing you should look for in a slot. The game should also suit your tastes and preferences. The overall prizes and features of a slot matter a lot too.

High-RTP Online Slots in 2021
  • Mega Joker by NetEnt (RTP: 99%)
  • Book of 99 by Relax Gaming (RTP: 99%)
  • 1429 Uncharted Seas by Thunderkick (RTP: 98.5%)
  • Blood Suckers by NetEnt (RTP: 98%)
  • White Rabbit Megaways by Big Time Gaming (RTP: 97.7%)
  • Big Bad Wolf by Quickspin (RTP: 97.3%)
  • Bonanza Megaways by Big Time Gaming (RTP: 96%)

Online Slot Volatility, or Variance

One more important thing to check for when playing online slots is, how volatile a slot game is. Volatility or variance of a slot means how frequently the game generates wins.

Game developers classify volatility as high, medium, and low.

Usually, slots that pay out big have high volatility. High volatility slots offer handsome rewards, but you may have to spin a lot to achieve those wins. On the other hand, low volatility slots offer smaller but frequent wins.

You’ll notice that most of the jackpot slots, such as NetEnt’s Dead or Alive, fall under the high-volatility category. That’s because they involve more risks, and hence give out bigger prizes. High variance slots are usually favoured by high roller slots players, or those with big bankroll.

How to Pick a Great Slot Game?

Playing the best slots online for real money is one of the most thrilling recreation activities. So what makes a slot game ‘the best’?

Different people look for different things when they enter an online casino. Some look to play the latest slot games for pure entertainment, while others head straight to the jackpot slots section to try for a life-changing win.

Whatever the individual preferences may be, there are some standard features which makes a slot game, great.

  • The Slot’s Payout – Well, it’s a real money slot machine, so it better have some decent winning options! The slot’s RTP for one, should be above average (> 95%), and for a game offering mediocre top reward, the slot variance (the risk factor) should be mid to low.
  • Features – New slot games usually come feature-loaded. Cascading Reels, Expanding Wilds, Sticky Wilds, Multipliers, In-Game Free Spins, Re-spins, Bonus Rounds, Megaways Engine, are some features which increase your winning chances and also make the games more thrilling.
  • Jackpot – Some online slots feature juicy jackpots apart from regular wins. These slots can have progressive or fixed jackpots. Some games even offer random jackpot drops – jackpot that get activated on a random spin!
  • Graphics: We live in a digital era of 3D graphics and animations, and so expect nothing less from the slot games. Thanks to advances in technology, today even mobile slots sport eye-catching 3D graphics and cinematic gameplay.

How To Play Slots Online

Much like in a land-based casino, online slots have the same mechanics, except that you play them on a computer or on your mobile phone.

  1. First, decide whether to play slots for free or real money. If playing in real money mode, it is better to go slow initially (set small bet sizes per spin) and understand the game.
  2. Decide on how many paylines you want to bet on. Playing on maximum paylines will offer better winning chances. However, it will also erode your cash balance quicker.
  3. Online slots can be played in manual or auto mode. In autoplay mode, the slot machine automatically spins the reels for a fixed number of times.
  4. The wins and prizes depend on the symbols produced on the grid after hitting the spin button. The rules and payouts of the winning combination varies from game to game.

Different Types of Online Slots

Traditional land-based slot machines, also known as fruit machines, usually consisted of a 3×3 grid of symbols. The symbols could be anything, from fruits, veggies or animals, depending on the game’s theme.

With the advent of slot sites, slots also diversified, and today are classified into various categories based on the number of reels, themes and payouts.

Online slots are classified into Classic or 3 reel slots, 5 reel or Video Slots, 3D Slots, Megaways Slots, and, the famous Progressive Jackpot Slots.

Video slots are also categorized based on their payouts as low, medium or high variance slots.

A high variance slot will generally have payouts far greater than a low variance slot, but at the cost of higher risks. A high variance slot may offer huge wins, but they may be few and far between. On the other hand, a low variance slot will generally give out frequent but smaller wins.

1. Classic 3-Reel Slots

3-Reel Online Slots are the online version of the traditional fruit machines that started out in the brick-and-mortar casinos. They are the simplest slots to play, and are thus great for new slot players.

3-Reel slots feature 3 columns (known as the Reels) and 3 rows. Generally the middle row is the only payline. Getting 2 or 3 matching symbols (usually from left to right) on the payline will award you the wins. The win amount will depend the value of the symbols and on the game’s payout table.

Newer 3-reel online slots have introduced more paylines to the games for bigger rewards and more engaging gameplay. Nowadays, many classic slots also come with the Wild and Scatter symbols. 3-Reel slots such as Super Joker Megaways even come with the Megaways mechanics (more on Megaways below) for more thrills and bigger prizes.

So, before playing, quickly check the game’s rules and get acquainted with the symbols and the winning patterns you need to get.

Some of the most popular 3-reel slots are:

  • Mega Joker by NetEnt
  • Break da Bank by Microgaming
  • 7s on Fire by Barcrest
  • Fire Joker by Play’n GO
  • Diamond Duke by Quickspin

2. Video Slots or 5-Reel Slots

5-Reel Slots, popularly known as Video Slots, are the bread-and-butter of slots sites. Hugely popular with the players, you’ll find them in the hundreds in all top casinos.

Video Slots built up on the classic slots, with the addition of more reels, more bonus features, newer themes, and newer ways to play and win.

Sporting 5 reels, 3 rows, and multiple paylines (some games boast of hundreds of paylines), video slots come with life-like graphics, engaging soundtracks, interesting gameplay, and numerous ways to win.

The biggest talking point of Video Slots are the bonus features they come with. Apart from the Wilds and the Scatters, these games come with a host of extra features such as Sticky Wilds, Avalanche Wins, Expanding Symbols, Multipliers, and in-game Bonus Free Spins. All these features are designed to offer an engaging and rewarding experience to the players.

The only downside of playing some newer, more complex video slots is the extra learning curve to get to know each game’s rules.

Some of the best and most popular Video Slots are:

  • Starburst, Twin Spin, and Gonzo´s Quest by NetEnt
  • Book of Dead by Play’n Go
  • Immortal Romance and Thunderstruck 2 by Microgaming
  • Book of Ra by Novomatic

3. 3D Slots

3D slots are the next-generation video slots that feature high-end HD graphics to give you a 3D- like visual experience.

They usually come feature-packed, offer the best animations and sounds, and boast of incredible graphics. Not only are the visuals stunning, but many of the new titles come with interactive gameplay, story lines, and varied themes.

Today, you have a great choice in 3D slots as more and more gaming developers are offering these high-end games. Some acclaimed suppliers of 3D slots are Microgaming, NetEnt, Yggdrasil and Betsoft.

Below are some 3D slots that are a must-play.

  • Vikings Go To Hell by Yggdrasil
  • Safari Sam by Betsoft
  • Big Bad Wolf by Quickspin
  • Cleopatra by IGT
  • Jumanji by NetEnt

4. Megaways Slots

Megaways Slots are video slots that feature a revolutionary mechanism, originally developed in 2015 by gaming studio Big Time Gaming.

Regular slot games have a fixed number of reels and paylines. However, Megaways Slots sport up to 6 reels and use a random modifier to change the number of symbols on each reel after every spin. This means, that the number of paylines change after every spin, and there are potentially thousands of ways of landing a win!

Each reel will have 2 to 7 symbols. The more symbols there are on a reel, the higher the number of paylines, and thus more ways to win.

For example, for a slot having 6 reels and 7 symbols per reel, the game will offer up to 117,649 Megaways (7 x 7 x 7 x 7 x7 x 7). Identical symbols on adjacent reels from left to right will form winning combinations. Usually, you’ll need at least 3 matching symbols on adjacent reels, starting from reel 1.

Nowadays, many top gaming providers are offering Megaways Slots. There are more than a hundred Megaways Slots that are packed with rewarding features, such as bonus rounds, respins, and multipliers.

Below are some of the best and most popular Megaways Slots.

  • Gonzo’s Quest Megaways from Red Tiger
  • Great Rhino Megaways by Pragmatic Play
  • Wheel of Fortune Megaways by IGT
  • The Dog House Megaways by Pragmatic Play
  • Aztec Gold Megaways by iSoftbet

Online Progressive Jackpot Slots

One of the attractions of playing slots online are the progressive slots. Also known as jackpot slots, these games come with massive jackpots that can go as high as several million Pound.

Progressive Jackpot Slots are usually networked over several casinos. The jackpot money is pooled into one big ‘pot’ from the players’ wagers. As the number of people playing the game increases, the pot also keeps growing until some lucky player wins the jackpot. 

Many people who play slots online dream of hitting these life-changing  jackpots. In most progressives, you must play with the maximum bet size to be eligible for a chance of hitting the big jackpot.

The biggest and most popular online progressive jackpot slots are:

  • Mega Moolah by Microgaming – The ‘Million Maker’ features 4 jackpots: Mega, Major, Minor and Mini.
  • Mega Fortune by NetEnt – its mega jackpot starts at £150,000.
  • King Cashalot by Microgaming – jackpot starts at £100,000.
  • Hall of Gods by NetEnt – biggest win of £7,800,000 so far.
  • Age of the Gods by PlayTech – comes with 4 progressive jackpots.
  • Divine Fortune by NetEnt – 3 different jackpots includes a progressive Mega Jackpot.

The biggest jackpots are known to have paid out winnings running into millions. Of course the odds are also staggering, and in the end it all boils down to one’s luck.

Online Slots Tournaments

Online slots tournaments are a fun way to play slots with a chance to win handsome prizes. Sometimes called slot races, a slot tournament is a competitive live event that is held between players over a limited amount of time.

Although the finer details and the rules of online slot tournaments can vary from one casino to another, the basic premise remains the same.

  • The slot game/games are pre-selected by the casino. You will need to play these games for a set amount of time (usually for a few minutes).
  • The players earn points on the winning spins or by completing various challenges of the game.
  • Once the time runs out, the players who gather the most points on the leaderboard win various prizes. The prizes can range from cash rewards to casino bonuses.

Online slot games tournaments come in a few variations. There are freeroll tournaments, that as the name suggests, do not require you to deposit any real money to play. They are not very lucrative though, and the prizes will mostly consist of small casino bonuses.

The most popular and rewarding tournaments are the buy-in slot tournaments. To enter them, you need to pay an entry-fee (usually about £50 or so) and the casino will give you some fixed credits to play the tournament’s games. Buy-in tournaments generally have handsome prize pools. Often, the top players on the leaderboard will be awarded real money prizes, while the lower ranked players are rewarded with bonuses.

Tips to Play Slot Tournaments

Although playing slots is mostly about luck, there are a few things you should keep in mind before playing in a tournament.

  • Play only in UK-licensed slot sites to enjoy safe and fair gaming.
  • Check the entry fee. Never spend more than you can afford to lose.
  • Go through the tournament’s rules, eligibility criteria, prizes, and the schedule.
  • As you’re playing with bought credits and not spending real money on every spin, bet max and spin as fast as you can.
  • Use your entire credit before the time expires.

The best slot sites in the UK regularly hold slot tournaments that feature top games and offer generous prizes. Casumo’s Reel Races Events are exciting online slot tournaments with juicy cash prizes. Similarly, Genesis Casino holds weekly tournaments and Daily Prize Drops on thrilling slot games.

Free Spins with No Deposit

No-deposit free spins are much in demand in online casinos. However, they are mostly offered only to new players at the time of signing up with a casino. By playing with your free spins on slot games, you can win real money without depositing any real cash in the casino.

Like all casino bonuses, no-deposit free spins offers also come with certain terms and conditions that you must fulfil before you can cash out any winnings.

If you’re looking to win actual money from free spins, do check that the offer’s wagering requirement is reasonable (such as 35x on Bonus, or lower). The maximum cashout allowed from the free spins’ winnings is usually about £100 only.

However, as no deposit free spins are almost always given to new customers only, existing players will find it very hard to claim this kind of offer.

In that case, your best bet is to claim free spins offers that are given after you make a minimum real money deposit. Though technically they can’t be called free spins, most casinos do give a generous amount of free spins on deposits as small as £10.

Also, worth noting is the game for which you are getting the free spins. Do you like the game? Does it offer a good winning potential? What’s the slot’s RTP? Usually, it’s harder to get free spins offers on popular, new games, and on jackpot slots.

Top Slots in UK Slot Sites

Below are some slot releases that we’ve grown fond of lately. We feel they are worthy to be counted among the best online slots. You will find all these games, and more, in the best UK slot sites listed above on this page.

Age of Asgard Slot by Yggdrasil Gaming

Released in 2019, Age of Asgard is a medium-high volatility slot that takes you to the realm of the Norse gods. It has an RTP of 96.2, bet range of £0.20 to £200, and a max win potential of £488,800. The game’s layout is striking, with two reels sets that spin separately, each having a 5×3 block and 20 fixed paylines.

The slot offers several rewarding bonus features, such as, Respin, Stack Wilds, Clash, Randomizer, Free Spins and a Ragnarok Free Spins. The Ragnarok is the most exciting and lucrative bonus round of the game which is triggered when you land 6 Free Spin symbols (3 in each ‘block’). Ragnarok features only high value symbols and can land you a win up to 1,200 times your bet.

Money Train 2 Slot by Relax Gaming

Money Train 2 is a high variance Relax Gaming slot with an RTP of 96.4% and a max win of up to 50,000x. Released in October 2020, Money Train 2 sports a Wild West theme and adds a couple of great, extra features to its predecessor, and now sports a Respin feature and a Money Cart Bonus feature.

The Respin feature is triggered when you land 2 bonus scatter symbols. The reels then respin with a x1 multiplier added until you score a win.

The Money Cart Bonus is triggered when you land 3 or more standard scatter or golden scatter symbols. Three re-spins follow, and multipliers in the range of 1x to 10x for the standard scatter and 20x to 200x for the golden scatters are added that increase your winning chances.

Money Train 2 slot also features a ‘Buy Feature’ that increases the base game’s RTP to 98%. You can directly enter the ‘Money Collect Bonus’ round by using the Bonus Buy feature for 100x your base bet. However, due to the UK gambling regulations, this feature is not available to British players.

Morgana Megaways Slot by iSoftBet

Featuring King Arthur’s arch enemy, the evil Morgaine or Morgan, the Morgana Megaways slot offers 2 to 7 symbols each on its 6 reels. The game has a 95.98% RTP (without Bonus Buy) and offers up to 117,649 ways to win.

2 to 6 matching symbols on adjacent reels (left to right) gets you the wins. Two features make playing the Morgana Megaways Slot totally worth playing.

Firstly, the Max Megaways feature, which randomly instructs every reel to show all 7 symbols to allow the max 117,649 ways to win.

The second great feature is the free spins bonus game. It is activated by landing 3 or more scatter symbols and can award you up to 30 free spins. In the bonus game, your goal is to collect symbols of the same type using your free spins. If you manage to collect 8 Morgana symbols the highest reward of 500x bet, 1 extra free spin, plus 117,649 Megaways, is all yours.

Imagine the adrenaline rush if Morgana Megaways Slot also had the cascading wins feature! Nevertheless, this Megaways slot is a lot of fun, with plenty of action and handsome rewards.

Online Slots FAQ

Are online slots random and fair?
Yes, if you play at a reputed British-licensed online casino. This is because the best slot sites in the UK offer games by reputed gaming providers only. For complete fairness of the outcomes, their slot games use the Random Number Generators (RNGs) – computer algorithms that produce random outcomes in the games. Furthermore, even these RNGs are tested and certified by reputed third-party auditors such as GLI (Gaming Laboratories International) and London-based eCOGRA (eCommerce Online Gaming Regulation and Assurance).
What is a slot machine’s RTP (Return To Player)?
RTP or a slots’ payout rate is a measure of how much that game will pay back to the players over a long period of time. It is expressed as a percentage of the total wagered money to the total winnings handed out by the casino for a particular slot game. The RTPs differ from one slot to another. It is set for each game by the game’s software developer. The higher the RTP of a slot, the better it is for the players. Today, most online slots have an RTP of 95% or more. Top UK slot sites display the RTP’s of all their games, and the UK Gambling Commission mandates the display of the games’ RTP in all UK slot sites.
Can slot sites change a slot machines’ RTP/payout?
To some degree, they can. Some gaming software providers do allow online casinos to change the games’ payout rates, but not to a great extent. UKGC regulations have made it compulsory that all casinos must display their games’ RTP values. You can check each game’s RTP in the game’s interface itself.
Are online slot sites rigged?
If you’re playing in a UK-licensed slots site, then you have nothing to worry about. All their games are rigorously and periodically tested for fairness by independent and renowned testing agencies, such as UK’s eCOGRA. However, if you’re playing in an unlicensed casino, then not only can their games be manipulated, but you can also lose your winnings and financial data. Always check a casino’s licensing details that are found at the footer of their website.
Do I need to install any software to play slots online?
No. These days, almost all casino games are developed such that they can be played right in the web browser, whether on desktop or mobile. If a casino offers a mobile app, you may download and install it for a better gaming experience on-the-go.
Which slot sites offers the best odds?
Most casinos do not publish their payout rates. However, UK-licensed slot sites must display each game’s RTP (Return To Player percentage). You can easily find the RTP value displayed inside each game’s interface. Higher RTP games will technically give you better winning odds. Look out for sites that offer high RTP games, great variety and hundreds of online slot games.
What are Free Spins in slot games?
Many online slots have in-game bonus rounds that awards free spins to players (not to be confused with free spins casino bonuses). To enter the bonus round, a player needs to get the correct symbols and patterns on the reels. Depending on the game’s rules you can win a number of free spins to play extra rounds of that game.
Can I play free slots online in the UK?
Yes, you can play slot games in free/demo mode, but only after signing up with a slots site. Only persons over the age of 18 years can register at real-money online casinos.
What are Progressive Jackpot slots?
Progressive Slots, also popularly known as Jackpot Slots, are online slots that offer mega jackpot prizes running into millions of Pound. These slot games are usually connected with their counterparts in other casinos and pool a part of the bettor’s wagers that keep accumulating in a central ‘pot’. The jackpot gets reset when some lucky player bags the prize money.
Can you play online slots for real money on a mobile?
Yes, of course. All top slot sites offer the latest online slots for mobile users. Almost all the slot games launched nowadays are mobile compatible, and many of the old classic slot games have been converted for mobile play. Online casinos also offer mobile casino apps for iPhone and Android phone users.
Do slot sites give out bonuses?
