What are online slots games?

Slots are simple games where you spin the reels to form a winning line. To form such a pay line, you need to land matching symbols. And when you do, you win. Told you, it’s simple.

The games are the adaptation of the physical land-based casino or pub slots that can be played on a desktop or mobile device. But with improved themes, features and gameplay.

One of the best things about slots is that there are so many different themes you can enjoy. From classic fruit and futuristic to fantasy and reality TV. Another great thing is that the software providers release new slots on a weekly or monthly basis. So, you’ll always find something to suit your playing style and budget.

Plus, you can play for real money or fun. Most of our recommended casinos have a good variety of games available in demo mode. Simply choose a slot and have fun without spending a penny.

We will explain in more detail what kind of slots you can play further down this page. But for now, let’s see how to spot a good online game.

Play slots and win real money

What makes a good online slot game?

It takes a little bit of practice to know what makes a good online game. But we’ve got some nice tips to help you pick the right slot. Here’s what you should look for when choosing an online game:

  • Bonus Features – A good slot game should have a blend of bonus features to help you form that winning line. And to be fun to play. Look out for bonus games and free spins feature, re-spins, multipliers, wilds, scatters. Also check if there are any expanding reels, colossal symbols, wins both ways, or 243+ ways to win. These make fantastic gameplay.
  • Compelling Theme – An exciting theme makes an exciting slot. Funny critters and mesmerising designs make games fun and immersive. Take the fabulous Book of Dead or Immortal Romance slot as an example. Or ancient Egypt themed slots like the Book of Ra. All have beautiful themes rich in colour and mystery.
  • Max and min bet – Min and max bets are important in slot machines and those that offer a max bet are the ones you should look out for. Especially because many of the online jackpots can only be won with the max bet. And in general, you get a higher payout percentage when betting max, depending on the slot.
  • Jackpot(s) – Who doesn’t love online slot games where you can hit a life-changing jackpot while having fun. While smaller jackpots might not be as attractive, big jackpots don’t get snagged very often. So, mix it up a little. Play a variety of jackpot slots.
  • RTP & Volatility – Good slots games have medium to high RTP. The higher the RTP, the better the payouts. But don’t rush to dismiss slots with lower than the average (96%) RTP. While many slots have a fixed return to player percentage, some can increase the more you play.
  • Mobile Slots – It’s always nice to have a high-quality mobile version of your favourite slot. Having the option to load up games on your smartphone is simply a convenience.

Why should you play online slots?

The excitement of potential winnings while having fun makes online slots some of the most popular online casino games. And, unlike table games, slots are easy to play and don’t require special skills. But there’s more to slots games than just easy fun. Let’s take a quick look at why you should play online slots.

  • Convenience – Not all of us have the luxury of jetting off to Las Vegas for a night of a lifetime. But, thanks to online gaming, you can join a casino online and play you favourite games anytime. More so, you can test many slots for free.
  • Wide Selection of Slots – Another perk of playing online is the infinite selection of slots available at online sites. You can access games with the best odds, the best graphics and the most entertaining gameplay, instantly. Check out our slot reviews to find out which ones are the top slots to play in the UK.
  • Play On The Go – You’ll never be out of slot action with mobile gaming. Most of the respected game developers create online games using HTML5 technology. This way they cater to players who love spinning on the go. Which is, let’s face it, the majority today.
  • Bonus and Special Features – Another reason to play online slots is for their extra bonuses, free spins and special features. Such components can positively impact your gameplay by creating more winning chances while enhancing your gaming experience.

These are just a few perks of playing at online casinos. Remember to check our recommendations for the best online casino sites in the UK.

What types of online slots can you play?

Find the Best Slots to Play Online

Not sure where to start to find the best slots? Have a look at the quick overview below. Here we’ve covered 4 most popular slot styles.

  • Video slots
  • Fruit slots
  • Jackpot slots
  • 3D slots

Video Slots

Derived from the traditional land-based fruit machines, video slots are the key games at many online casinos. Each of the games has a different number of reels, rows and pay lines. They can also come packed full of special features such as bonus games and free spins. Think of fun slots such as NetEnt’s Gonzo’s Quest or the legendary Book of Dead by Play’n GO. You just have to choose the right casino.

Fruit Slots

Fruit slots go way back to the days when online gaming wasn’t so easily accessible. They were simple pub slots that featured fruit symbols on the reels. Players liked them because they were easy and fun to play.

Today the best online fruit slots have added features, colour-bursting graphics and captivating soundtracks. Why not try Microgaming’s Deco Diamonds, Twin Spin by NetEnt or Imperial Fruit by Playson. We have them all at JohnSlots.

Jackpot Slots

These kinds of slots are known as millionaire-maker slots. Think NetEnt’s Mega Fortune or Microgaming’s Mega Moolah. Online jackpots here are linked across many different online casinos and grow until they’re bagged by a lucky player.

If you fancy giving it a go, check out our list of the top progressive online jackpot slots and where to play them.

3D Slots

3D slots are enriched with HD graphics making the games super fun to play on both your desktop and mobile. Jungle Jim El Dorado by Microgaming is a good example. Enhanced with beautifully crafted symbols it also comes with many special features.

Among many captivating 3D slots, the epic Yggdrasil’s Vikings go to Hell slot has also been stealing the headlines. Loaded with plenty of bonus features it’s worth giving a quick spin.

All of the favourites – slots, table games and progressive jackpots – are here, under one roof.

2. Mr Green

There are casinos and there’s Mr Green casino. Stylish, friendly and very intuitive, the site is home to some of the best and most popular casino games. With over 800 exciting titles from NetEnt, Yggdrasil, Play’n Go, and Microgaming, it’s an award-winning gaming site not to be missed.

3. Genesis

Imagine a place where you have access to 1,300+ casino games. Where you can play slots designed and built by some of the industry-leading software providers. What if we told this place exists? In a faraway gaming galaxy Genesis, home to the most popular slots games.

4. Genting Casino

With more than 50 years of experience in the online and offline casinos, Genting sure knows a thing or two about the casino business. Expect a good mix of entertaining mobile-optimised slots from top providers as well as mega jackpots to win you some of that cash.

Best Online Slots Games

With an infinite amount of games, how do you even begin to decide what are the best slots to play online. We feel your pain so we sent our slots team to do the digging. They say the top 10 online slots below are a good place to start.

Gonzo’s QuestNetEnt
Mega FortuneNetEnt
Book of DeadPlay’n Go
Immortal RomanceMicrogaming
Mega MoolahMicrogaming
Vikings Go To HellYggdrasil
JokerizerYggdrasil
Blood SuckersNetEnt
John Hunter seriesPragmatic Play

1. Starburst

This gem of a game is one of the most recognisable slots in the iGaming industry. Players just can’t get enough of its dazzling gem-encrusted theme and win both ways expanding wilds.

It’s also a medium variance slot meaning that the wins here are frequent. And despite the lack of in-game bonus features, Starburst is still one of the top online slots from NetEnt.

2. Gonzo’s Quest

Beautifully crafted, equipped with tumbling reels and increasing multipliers, Gonzo’s quest is one of the best slots to play online. It’s highly entertaining, with frequent payouts and beautiful Aztec jungle theme.

Just like Starburst, Gonzo’s Quest slot is not a game of many special bonuses and yet it’s stolen many players’ hearts.

3. Mega Fortune

Known as the millionaire-maker slot, Mega Fortune is well-known among the slots enthusiasts. It’s all about the luxury here. The yachts, the sparkle, the champagne. NetEnt sure knows how to create immersive gameplay.

And with 3 jackpots up for grabs, it never stops featuring among the top 10 online slots to play in the UK.

4. Book of Dead

If we had to list the best online slots in the UK, the Book of Dead slot would make the cut. The graphics here are stunning. This high variance game comes with many in-game bonus features to help you win including free spins, expanding wilds and scatter symbols.

A risky game though. Just like the many other online slots by Play’n GO.

5. Immortal Romance

Immortal Romance is such a vivid online slot and one of the top slot games from Microgaming. It comes with 243 pay lines, a multifold of bonus features and big payouts.

The supernatural vampire theme is exceptional too, expertly executed with detailed graphics and an eerie soundtrack. We can’t fault this game.

6. Mega Moolah

Microgaming’s Mega Moolah is another record-breaking slot game that could bring you many riches.

It’s rigged with 4 progressive jackpots: Mini, Minor, Major and Mega. Each starts at 10, 100, 10, 000, and 1 million respectively. And because the slot pays out randomly, you can win on any spin. As a rule of thumb, the higher you bet, the bigger the payout.

7. Vikings Go to Hell

A strong favourite by Yggdrasil is the hardcore Vikings go to Hell slot. The last but not least in their Viking-themed trilogy, the slot is brilliant, beautiful and extremely high-risk.

It’s not your ordinary gentle game from Yggdrasil’s slot collection. But if you think you can handle the pressure, then join the Vikings, collect your rage points and go battle the fallen angel.

8. Jokerizer

This Yggdrasil slot grows on us each time we play it. It’s fun, well made and pays both ways but comes as a high variance game. It has one special in-game feature, the Jokerizer Mode, to help you win some cash. If you are lucky, you can win 600x your bet here.

Don’t expect to win too often but do give this slot a spin. It’s the players’ favourite for a good reason.

9. Blood Suckers

UK players love the vampire-slaying Bloodsuckers. With endless payouts and rewarding bonus features, it makes a fun and spooky gameplay.

More so, the slot comes with lots of great in-game features and a 5-level bonus game. Here you could land a 2x or 3x multiplier, depending on your luck.

10. John Hunter

We’re super excited about John Hunter since we haven’t had the chance to mention any of the Pragmatic slots yet. The adventurous Indiana Jones inspired online game comes with several bonus features and astonishing 7,776 ways to win.

It’s also volatile so beware of lack of payouts. You’ll need 5x or higher multipliers to land a win. A piece of quick advice would be to stay calm and look out for those bonus spins. This is where the real treasure lies.

Best Slot Game Providers

Many online games providers deliver on their promise to create fun video slots. But only a handful put their heart and soul into the slot development process. And only those that do, have made it to our shortlist of the top game developers in the UK. Take a look.
