Top 10 Best Online Slots

The number of different slot games out there is almost endless, and with themes ranging from Ancient Egypt, to animals, to classic-style games, there’s something for everyone. The slot games you’ll love will depend on your own personal preferences when it comes to not only the themes, but also the game’s special features like bonus rounds, special symbols, and paylines. If you’re looking for your new favorite slot game, these are some of our top picks:

Age of The Gods

There’s a whole series of Age of the Gods slots, and you can play them at top online casinos like BetVictor. Brought to you by Playtech, these games are themed around ancient Greek mythology, so you can expect really immersive graphics, animations, and soundtracks to transport you to this different world. With special features like extra wilds and multipliers, plus 20 paylines, the Age of the Gods slots all come with a good chance of a win. The best thing about these games is that they hold seriously huge progressive jackpots, so you could be walking away with a prize of up to six figures.

Zeus Thunderbolt

Dream Vegas and other top UK online casinos have lots of games themed around mythology, and Zeus’s Thunderbolt is one of our top picks. With 30 paylines and a maximum bet of £5 per line, you could be in for a seriously huge win.

Land five of the Zeus icons and you’ll win 2,500x your stake, plus the game comes with wilds, and a respins feature. There are also scatter symbols, which award the special bonus game of 10 free spins, but you’ll also have the option to purchase your way into the bonus round so you don’t have to wait for it to trigger.


If you’ve ever played at an online casino, you’re more than likely to have come across Starburst at some point - this NetEnt title is widely regarded as one of the most popular slots of all time. You can play Starburst at LeoVegas, which is no surprise given how impressive their game selection is.

Starburst doesn’t come with any complex gameplay or bonus rounds, and the simplicity means that it’s the ideal game for newer online casino players, so you could look to use any free spins on it. There’s a “win both ways” feature which gives you extra chances of winning, and it comes with a pretty high RTP of 96.1%. You’ll even have the chance to win a maximum top prize of £50,000.

Book of Dead

There are loads of “Book of” slot games that you can play at top casinos like Casimba, but Book of Dead by Play’n Go is among the best of them.

Set in an ancient Egyptian tomb, you’ll be going on a journey with explorer Rich Wilde, and when you play you’ll need to look out for the special book symbol which acts as the scatter and awards you the free spins round! There are also expanding symbols to increase your chance of a win, plus Book of Dead comes with 10 paylines and an RTP of 96.21%, so it’s an excellent game to try.

Eye of Horus

Eye of Horus is one of many Ancient Egyptian themed games that you can play at 21 Casino. Created by Reel Time Gaming (a smaller studio), Eye of Horus is themed around the mythical Egyptian god, and the slot comes with a whole lot of special features like symbol upgrades, a bonus round of 12 free spin that can be re-triggered, and the chance to win an impressive fixed jackpot of 10,000x your stake! Eye of Horus has an RTP of a higher than average 96.31%, so you might just get really lucky when you play.

The game is by Triple Edge Studios, and come with 5 reels, and a total of 720 paylines - that’s a lot of ways for you to win! If you get really lucky, you might win the top prize of 5,000x your stake.

This slot game is absolutely jam-packed with special features, like Wild Stacks (where wild symbols merge together), a collection pot, an increasing free spins multiplier features, and a free spins round that comes with a 5x multiplier. There’s even a jackpot wheel that can award you with a cash prize.

Big Bass Bonanza

You don’t have to be a fisherman to love the Big Bass Bonanza game (available at Karamba Casino) and its whole line of spin offs. The game comes with an above average RTP of 96.71%, and high volatility, and of course the impressive graphics and gameplay that you can always expect from Pragmatic Play titles.

If you land enough special symbols to trigger the bonus round, you could be awarded up to 10 free spins! The bonus round comes with multipliers, and cash symbols, plus you can re-trigger the spins. If you’re playing with the maximum stake, you could win over £500,000 if you’re lucky enough to reel in the top prize.

Emperor Of Rome

Emperor of Rome is a Playtech title that’s part of the Mega Fire Blaze series, available for you to play at bet365. This game is a pretty recent release, and it comes with an RTP of 95.88%, and a low volatility.

This game is set in the Colosseum, and you’ll be looking out for high value symbols like helmets, shields, and characters like Julius Caesar and even Cleopatra. If you land enough of the special Colosseums symbols, you’ll open up the bonus game, and if a coin symbol appears on the reels, you’ll double your win. These are some really unique and exciting special features.

Gold Blitz

If you love games themed around cash, you’ll love Gold Blitz, available at BzeeBet. The game is produced by the aptly named Fortune Factory, and features a game grid of 6x4 reels, and a massive 1,024 paylines.

While you’re playing, look out for the wild symbol that substitutes for other symbols, or land the collect symbol that rounds up more wins on your game grid. There are two different free spins features, both of which come with wild multipliers, and the ability to re-trigger the bonus round.

Types of Online Slot Machines

Classic Slots

If you picture the type of slot games you’d expect to see in a old-fashioned casino, you’re probably thinking of a classic slots games. These classic slots are usually very straightforward when it comes to gameplay and have a limited number of paylines and special features. The online versions of these games are designed to mimic the look of retro slot games, and the symbols you can expect are along the lines of bars, sevens, and fruit.

Video Slots

Video slots are the more modern-looking cousins of classic slot games that you might find on casino apps. These are the ones that tend to each have their very own theme and special characters, along with extra features like wilds, multipliers, and free spins. Video slots are highly immersive, and even come with animated elements and fun soundtracks! The symbols are also highly themed, so depending on the game, you could be looking out for magic carpets, huge fish, or illusive books.

Progressive Jackpot Slots

You might have come across some progressive slots (like Mega Moolah), where the top potential payout can go up to seven figures - these are usually progressive jackpot slots. The progressive jackpots increase every time someone anywhere in the world plays those jackpot slots games, that’s why it can get so big! Progressive jackpots can drop at any time, and usually the progressive slots have a few different levels of jackpots, so even if you don’t win the biggest one, you might still be lucky enough to get something special from jackpot slots.

Megaways Slots

When you play megaways slots, the number of ways to win is dramatically increased and can potentially go into the hundreds of thousands! This is because the number of symbols that land on each reel changes with every spin on megaways slots, which makes things really exciting. Megaways slots have been popular for years, and many of the top providers make them and can be found at many Apple Pay casinos.

Interactive Online Slots

While every online slot game uses Random Number Generator technology and has a built-in RTP, there are some games where you’ll feel a little more like you have some control of the outcome (even if you don’t!). Some slots come with a gamble feature, where you need to guess the outcome of what is essentially a virtual coin toss, to stand a chance at increasing your winnings, and other slots let you choose your special feature, adjust the volatility of the game, or spin a wheel to get a prize.

Slots With Bonus Games

Many online slot games come with a special feature where you can win yourself some slots bonuses. Usually in the form of bonus games or free spins. You’ll usually trigger slots bonuses by landing enough of the special “scatter” symbols anywhere on the reels, and then you could get anywhere between about five and 20 free spins, depending on the game. You have a chance of a real win with the free spins spins, and any free spins winnings will be added to your balance.

Best Online Slots Site Offers

Claiming special offers is a great way for you to boost your bankroll at a new online casino and use your increased funds to try out loads of fun slot games! Almost all online casinos have a new player offer, but freebies shouldn’t end there - top UK slot sites also have special offers for regular players, and even VIP programs for the high rollers.

When you sign up for an online casino account through a link at Bookies.com, we’ll make sure you’re eligible for the very best possible offer, whether that’s a big matched deposit bonus, handy free spins, or even some cash back on your early losses.

These are the types of online casino offers you should look out for.

Free Spins

Free spins are exactly what they sound like - these are spins that you don’t need to spend any money on, but you can use them on top real money slots and stand a chance at a real win. Some online casinos give you free spins just for signing up, while others require that you make a deposit first, and then you might get your free spins all at once, or in batches each day. Free spins are usually restricted to use on certain games, which can be a great way to discover games you wouldn’t have played otherwise.

Bonus Games

“Bonus games” is a term that some online casinos use interchangeably with “free spins”, when you need to make a qualifying deposit to get them. The active bonus spins are usually given on one game or a choice of a few, and you might need to meet wagering requirements before you can withdraw your winnings, just like you would with a welcome bonus. Don't forget bonus funds expire, so be sure to read the terms and conditions.

Deposit Bonus

A deposit bonus is a form of casino credit that you get when you make a qualifying deposit of a specified amount. The most common variation of a deposit bonus is a matched offer, where you’ll get a certain percentage match on your deposit, for example 100% or 200% up to a specified amount. Deposit bonuses offer a lot of flexibility, as you can generally use them on any slot game (sometimes with a few exclusions).

No Deposit Bonuses

A free spins no deposit bonus is a rare type of offer, but you should definitely look out for these as they are pretty much risk-free. Some online casinos give you a small amount of free casino credits to use on games of your choice, or a few free spins on a certain game. No deposit bonuses are the perfect way to decide if you like the game selection and features of an online casino, before you play for your own money.

Loyalty Programmes

While almost all online casinos have something for newbies, the best online casinos keep on rewarding you throughout your journey. Loyalty programmes might award points for your play, allowing you to move up levels and get better bonuses, or they might simply give you special bonuses and promotions as often as every day!

The big slot game providers like NetEnt, Pragmatic Play, and Games Global release new games on a regular basis, usually in batches of about two or three at a time, so the variety at your favourite online casino won’t ever get stale! We’d recommend checking the “new games” section in the online casino lobby every time you log in to see what’s new. You should also sign up to marketing emails from your online casino, so that you can get all the news about the latest releases delivered straight to your inbox.

How to Play Online Slots

Even if you’ve never played online slots before, you’ll have just as much of a chance at a win as the next person. There’s no strategy for playing slot games, and because it’s all up to chance, there’s not much you can do to increase your chances of a win. Put simply, it’s as easy as pressing the “spin” button!

To make sure you understand the gameplay and ways to win, you can check the payable within the game info of the slot once you’ve opened it up. Here you’ll see all of the ways to win, as well as the different symbols and their value. Remember, you want to see the higher value symbols land on the reels, as these will give you a bigger win! All that’s left to do is select your bet per line and number of paylines, and start spinning. Almost all slot games have an “auto play” feature, so you don’t need to click the button manually to spin each time.

Most slot games work the same way - you need to match the same symbol on adjacent reels from left to right, on active paylines. This varies for some slots, for example games that have “cluster pays” or the “win both ways” feature. Thanks to Random Number Generator technology, you don’t have any influence over which symbols land.

Online UK Slots Sites Offers Terms and Conditions

It’s safe to say that all casino offers come with their own set of T&Cs, and we’d be a bit worried if we saw an offer that didn’t have any terms! There’s a pretty standard set of terms that apply to most online casino offers, but they do vary a little between the different casinos, so we’d recommend reading the T&Cs in full before you claim your offer.

Wagering Requirements

Most online casino promotions come with wagering requirements. This is the number of times you need to play through your bonus, deposit and bonus, or free spins winnings, before you’ll be eligible to withdraw. It’s always best to look for an online casino offer that has the lowest possible wagering requirements, and some offers even forgo these entirely, so you can withdraw your winnings immediately.

Time Limits

You shouldn’t be too concerned if you see a time limit applied to your deposit bonus or free spins - most online casinos have these. You might be required to claim your bonus within a certain timeframe after becoming a new player, use your free spins or matched offer within a specific amount of time, or meet the wagering requirements within a certain amount of time to be able to withdraw.

Win Limits

Win limits usually apply to no deposit bonuses, so for example if you get 10 free spins on deposit, your win limit from those spins might be £10. However, win limits can also apply to deposit bonuses, so it’s a good idea to read the T&Cs carefully, as anything over your win limit might be forfeited.

Game Restrictions

Game restrictions can apply to free spins or matched offers, and they refer to the games you can use your bonus on. This is particularly important if you’re claiming a free spins offer, because you’ll need to check which games they’re valid on (usually just one game or a limited selection). Most deposit matches can be used on all slots, but there are sometimes exclusions like very high RTP games, jackpots, and live dealer games.

Withdrawal Limits

Many online casinos have a withdrawal limit, which can be per day, week, or month. Withdrawal limits are usually in the thousands, so they shouldn’t impact you unless you have a massive win, and in that case you might be able to ask the support team to raise your limit. VIP players also usually have higher withdrawal limits.
