🏆 10 Most Popular Online Slot Games

There are literally thousands of slots available to play at online casinos and slots sites, and new games launch every single week. But despite this variety and fast-changing market there are a handful of slots that are timeless classics that British players come back to time and time again.

Welcome to our run down of the Top 10 Best Slots of All Time:

10. Wolf Gold

Pragmatic Play‘s Wolf Gold will leave you howling for more with its exciting bonus features and its promise of mini, major and mega jackpots. This beautiful game will transport you to a starry desert where you meet a range of wild west animals including an eagle, a puma, a buffalo, a stallion and of course the legendary wolf. Each animal will get you up to 500 coins, and the lone wolf counts as a wild symbol.

The special features of this 5-reel slot include stacked wilds, free spins, mega symbols, and a Money Respin feature to increase your chances of winning bigger prizes.

To play Wolf Gold, head over to 888 Casino and enjoy a generous 100% matched deposit bonus up to £200 to double your casino funds.

Best slot 10

Starting our Top 10 Best Slots of all time is the fantastic Wolf Gold from Pragmatic Play.

9. Mega Moolah

The Guiness World record for highest online slot payout of all time is held by a British man who won £13,209,300 on the Mega Moolah jackpot on 6 October 2015. This game is certainly Microgaming‘s biggest success story, and it can be found in many British casinos.

The original Mega Moolah has an African Savannah theme, and this is one Big Game worth going on safari for! The slot has five reels with 3 symbols showing on each, and 25 paylines in the base game. A cut of every spin goes into the progressive jackpot, and the kitty can grow to a nice six figure sum!

If you want to play Mega Moolah and be in with a chance of becoming a millionaire then head to Zodiac Casino where just £1 will get you 80 free spins!

Sticky Win Re-Spins will hold the winning cluster in place and spin the reels around it to try to increase the winning combo.

How We Review Slots Games

There are many different factors that make us consider a game as a great slot game. These are the elements we take into account when reviewing and recommending online slots:
1


Return to Player (RTP)

This percentage is the amount of money you can expect to win back from a game over a long period of time. Most online slots return 95-97p per £1.
2


Volatility

Low Volatility slots will pay out similar amounts for each win. Higher volatility slots have the bigger prizes, but these occur less frequently.
3


Software & Game Developer

There are hundreds of studios producing slots games on different software platforms, each with their own strengths and special features.
4


Free Spins

Many slots have in-game free spins that help make your money go further.
5


Bonus Rounds

Modern slot games have heaps of bonus rounds and features that increase the fun and give the potential to super-size your win multipliers.
6


Visuals & Sound

The latest software developments mean that players can enjoy 3D graphics, state-of-the-art animation and cinematic sounds when playing online slots.
7


Theme

There is an element of personal taste involved here, but we prefer games that take a fresh and original approach to a concept over those that are just trying to cash in on the latest hot slot.

🎰 Types of Online Slot Games

When the first slot machine was patented in 1894 the game was a much more simple affair than today’s more immersive and imaginative slots. We have come a long way from the early one-armed bandits and fruit machines where players just pulled a lever and matched three symbols across the centre of the reels. Here are some of the most popular types of slot games you will find in online casinos in 2022:

Classic Slots

There are many classic slot games that faithfully recreate the experience of traditional mechanical slots, with a modern twist. These games normally have a good RTP and a low variance, meaning that you can expect to win smaller amounts more frequently than when playing more high-octane slots. Classic slots normally come with 3 or 5 reels and only have 1-25 playlines making them easier to get the hang of. A popular classic slot is Starburst by NetEnt.

Video Slots

Technically all online slots are video slots, but normally when casinos and players talk about “video slots”, as opposed to other types of game, they are referring to slots that have a more immersive storyline with great visuals and sound. Video slots often have 5, 7 or even 9 reels., and offer more paylines, often boasting 243, or 1024 ways to win. Bonus rounds are a major attraction in this game, and these can step away from the reels and offer a different playing experience with exciting mini-games. A popular video slot is Gonzo’s Quest where we follow the protagonist in his search for the lost city of gold: El Dorado.

Branded Slots

Fan’s of popular culture can find their favourite shows, stars and bands in online slot form. The bigger game developers licence the rights to hit movies, popular TV shows, and even comic books. Our current favourite branded slots are Jurassic Park Online, Gordon Ramsey’s Hell’s Kitchen and Knightrider.

Progressive Slots

Most slot games in a physical casino have a jackpot prize that is set by the casino or developer. Progressive slots are different, and the jackpot grows every time a bet is placed. Some progressive jackpots are locked to just one slot at an online casino, but the larger jackpots will be shared across a number of games, meaning that you can be in with a chance of winning whatever your taste in slots. Although the odds of winning a jackpot are slim, the payouts are epic and can get to millions of pounds. Mega Moolah is a popular progressive jackpot slot.

Megaways Slots

Megaways slots are increasingly popular in the UK, and you can find Megaways versions of most of our favourite games. While traditional online slots have a fixed number of reels and paylines, Megaways games have a random reel modifier that changes the number of symbols and the layout with every spin. You can have up to 6 reels with 2-8 symbols showing on every spin, creating up to a maximum of 117,649 paylines. Bonanza was the first slot to use the Megaways Mechanic in 2016 and is still a great game to play years later.

🍒 Online Slots Basic Terminology

When you read a review of a slot game there might be many unfamiliar words and concepts. Here is a quick rundown of some of the main terms that will help you understand how an online slot game works:

Slot Reels

The reels of online slot games are generated by a software program that randomly chooses a symbol with each spin. The symbols of online slots can appear in any random order, and most online slots have between 3-9 reels.

Online Slot RNG

Online slot machines are run by a Random Number Generator (RNG) which determines where the symbols on the reels land in each spin. We only recommend slots sites licensed by the UK Gambling Commission (UKGC) which needs the casino to prove that the RNG is truly random and that it is checked regularly. This means that the slot games are fair, and that there is no way to fool the system or rig the wins.

Winning Combinations and Paytable

To win on a slot game you need to line up the symbols on the reels. Different symbols and combinations will give you different win multipliers, and you can check out the Pay Table in the slot game when you are playing. Wild symbols will normally swap in for any other symbol along the payline.

This is the Paytable for Starburst. If you are lucky enough to line up 5 BAR symbols along the reels your winnings will be the bet you placed x25:

Slots paytable

The Pay Table in a slots game lets you know how much you will win for each combo as a win multiplier.

Paylines

Traditional fruit machines only paid out when the right symbols were lined up along the centre row. Nowadays playing slots is much more exciting as most online games have a greater number of paylines along which you can find a winning symbol combination.

The number of paylines on a casino slot will determine how many ways you can win while spinning the reels, and these are normally read from the leftmost reel to the right. Starburst, for example, has 10 paylines as shown in the picture below, but this slot also pays both ways so you can also win from right to left!

slot paylines

Starburst has 10 paylines and you can win both ways!

Before you spin the reels in some games you can choose how many lines you wish to play and in which combinations. So if a slot has 24 paylines you can choose to bet only on 10 and specify which combinations i.e. paylines 1-6 and 21-24. You can also decide how much you want to bet on each line.

Max Bet on Online Slot Games

How much you can bet on a slot game will vary depending on its min/max bet limits, and the number of paylines. Every wager you make will deduct coins from your balance, and you will need to place a bet for every payline you select. The minimum bet is 1 coin, so if you want to play a slot with 10 play lines you will need to bet 10 coins minimum. The value of coins varies between slot games with some letting you play for pennies and others requiring a minimum bet of £1.

If you are playing a slot game to work through the wagering requirements of a free spins bonus or casino welcome offer, be aware that there may be a max bet limit attached to the deal’s Terms & Conditions. You often need to work through wagering requirements with many smaller bets rather than risking it all on a handful of spins.

Slot Games RTP (Return to Player)

One of the key statistics to check out before you start playing a slot game is the Return to Player (RTP) as this tells you how much money you could potentially win back. This is expressed as a percentage, so for a game with 95% RTP you would expect to win £95 for every £100 you bet.

This percentage is the statistical rate of payout over a long period of time, and so is not a guaranteed return. One player may play £100 and not win a penny, whereas another could hit the jackpot on their very first spin. This figure is most useful when you want to compare different slots.

Online slots are known to have higher RTPs than physical machines in land-based casinos, partly because of the lower overheads of running a slot site compared to a real-life venue (i.e. staff, rent, utilities etc). You can expect the majority of online slots to have an RTP between 95-97%, but there are some games that go even higher. Rainbow Riches Pick ‘N Mix, for example, boasts a max RTP of 98%, making it an ideal game to choose when playing through bonus wagering requirements.

🍋 Slot Games Bonus Features

It was very rare for old school slot machines to have many exciting features, as this was limited by the reels and software back in the day. Now in 2022 the potential for bonus features and more complicated mechanics is nearly limitless, making gameplay much more exciting and offering many more ways to win.

Slot Bonus Games

More and more online slots come with mini-games as a bonus round. These add a fun new dimension to spinning the reels online. You trigger these games by getting a certain combination of symbols, and if you beat the game you might win money, points or free spins.

There are loads of different bonus mini-games, some of which test your skill and others that rely on luck when you spin a wheel or pick a chest. If you want to play slots with bonus games try out mFortune – an independent casino site with some unique and imaginative slots that are chock full of exciting mini-games. Our favourite is the Buster Ghost slot which has three spooky mini-games: Psychic Shock Shack, Scare Stairs and Possession Session.

Wild Slots

Wild symbols are the most common type of bonus feature in online slots. When they appear they can stand in for any other symbol and make more winning combinations. Some types of wilds go even further and can help you score even bigger wins:

  • Expanding Wilds: stretch horizontally or vertically and can even cover the entire reel.
  • Sticky Wilds: hang around on the reels for the next spins.
  • Shifting Wilds: can move from one reel to another.
  • Random Wilds: show up when you least expect them and can act in surprising ways.
  • Stacked Wilds: will expand to cover more of the reel they land on.
  • Walking Wilds: will shift along the reels as all the other symbols benefit from free respins.

Scatter Slot Games

Scatter symbols do not need to be aligned on a payline to trigger a bonus or win. In most scatter slots, when 3, 4 or 5 scatter symbols appear anywhere on the reels the bonus will be paid, or a feature game will launch. NetEnt‘s popular slot Dead or Alive has a sensational scatter symbol that triggers some great win multipliers.

Win Multiplier Bonus

Many of the slots bonuses you win while spinning the reels online are Multiplier Bonuses. In this type of bonus round you normally progress through several stages earning a higher multiplier for each one you overcome. These rounds can help transform an average winning combination into a much higher cash prize.

Win Both Ways Online Slots

In most slot games the paylines are read from left to right, so if you line up three symbols starting from anywhere other than the first reel the winning combination will not be counted. In Win Both Ways slots combinations are also read from right-to-left, giving you almost twice as many chances to win.

243 Ways to Win Slot Games

Some video slots do away with the idea of paylines and just give you 243 Ways to Win instead. These 5-reel slots show 3 symbols on each reel and the wins are read left to right, but it doesn’t matter which position the winning symbols are in (top, middle or bottom) as long as they are on adjacent reels.

Before you spin you choose how many coins to bet, but you do not need to select paylines to place a stake on as you will get paid for every possible winning combination. This makes playing the game much more simple, but be aware that these games have low volatility and smaller wins because there are so so many ways to win.

A classic 243 ways to win slot is Immortal Romance by Microgaming, which has a popular storyline of vampiric love.

1024 Ways to Win Slot Games

Like their predecessors, the 243 ways to win slots, 1024 slots offer even more ways to win! These games show an extra symbol on each reel, upping the number of ways to line up the combinations across the five reels to a maximum 1024 wins in a single spin (4 x4 x4 x4 x4).

A good 1024 ways to win slot is Lucky Panda by PlayTech.

Free Spins

In-game Free Spins are a bonus feature that give you extra chances to spin the reels without betting your own money. You normally collect these in a game when a certain combo of Free Spins or Scatter symbols appear on the reels.

Slots sites also have Free Spins promotions where they give players the chance to play games for free. This is a great incentive to try out a new online slots site, or sample a new game, and you can find the best free slots bonuses in our list above.

Cluster Pays Online Slot

Cluster Pays are another type of slot games that doesn’t have paylines. Instead you win by forming a group of 4 or more symbols that are attached either horizontally or vertically anywhere on the reels. One of the most popular titles is Aloha! Cluster Pays and you can collect 100 bonus spins on this game from Slotnight when you make a minimum deposit of £10.

📱 Mobile Slot Games

If you want the convenience of playing slots on your phone you no longer need to hunt for a special mobile slots site or dedicated slots app because virtually all casinos are fully optimized for mobile players. Not only can you expect the same quality of gameplay on your phone compared to your desktop, most games are now designed on a mobile-first principle, so they are best played on mobile devices.

Most online slots can be accessed through the browser on your mobile for instant play, and many slot sites have mobile apps for both Android and iOS devices.

🎁 Free Online Slot Games

It is possible to play most online slots in demo mode before you decide to bet with your own cash, but it is much more exciting to play real money slots with a free casino bonus. Most slots sites give new players free spins or cash credit to try out their platform and best games.

The UK Gambling Commission regulations dictate that that you must be registered at an online casino before you can try a game in demo mode, so why not grab a free sign-up bonus from one of these great sites:

FAQ

1️⃣ Are online slots rigged?

Online Casinos have absolutely no way to control the outcome of any of their slot games. As part of the UK Gambling Commission’s licensing process slot sites need to guarantee that the outcome of every spin is random by having their Random Number Generator (RNG) certified and regularly tested.

2️⃣ Can I play online slots for free?

Many online slots sites give new players the opportunity to play for free so that they will try out the site. You can win real money playing slots with free bonuses, but be aware that you will need to meet the wagering requirements before you can withdraw your winnings as cash.

3️⃣ Should I only play casino slots with high RTP

Many slot reviews will tell you that bigger is always better when it comes to a game’s return to player percentage, but this is not necessarily true. Because this figure is calculated over long-time frames you are in no way guaranteed to make back that much money as online slots use random number generators.
