Choosing the best online slots

With heaps of slots to choose from, determining which games to play is a challenging task. Just as you find rows and rows of slot machines in land-based casinos, the range of online games you’ll find on EnergyCasino - one of the best online casinos, is endless.

Which are the best slots to play? It’s important to keep in mind that the slot mechanisms and basic rules underlying online slots are practically identical. Therefore, the probability of winning more money from one particular slot to another is based on luck and not on the mechanisms of the slot itself.

Here are some factors you need to consider if you want to select the best slots for you, regardless of your level of expertise:


  • Most entertaining theme: Online slots should primarily be about having fun, and then just hope luck will befall you some time or another. Which theme appeals to you most? Fruit-themed or Egyptian-themed slots?
  • Desktop or mobile: If you’re more into playing on the go, you need to choose mobile-friendly slots. Why not check out NetEnt’s Touch game versions?
  • Payout rate (RTP): How much money (in relation to your stake) will the slots pay out over time? The higher the return to player rate, the better! But do remember that this is just an average which evens itself out over thousands of spins.
  • Cost per spin: A spin’s minimum bet may be as low as €0.10c in certain slot games, but it could be higher in other slots. How much are you willing to stake? Find casino games which are within your budget to protect your finances!
  • The number of paylines: This ties up with the previous point, as the cost per spin is calculated by multiplying the number of coins being played by the number of active paylines. A higher number of active paylines may increase your chances of hitting a win.
  • Volatility: Slots can be with a high, medium or low volatility. High volatility slots will pay more, but less frequently, while low volatility slots will pay less, but more often.
  • Jackpot size: Many slots have a higher chance of providing you with small and medium bonus wins, while those with progressive jackpots may lead to bigger wins, if you lucky. Do remember that you must wager the maximum bets to win the maximum rewards, and keep in mind that the odds of hitting the jackpot are quite low.



Most popular slots on EnergyCasino

Now that you know what to look out for when selecting online slots, it’s time to go through some of the best slots on our online casino. In this guide, we’ve infused both recent slots and classics which haven’t aged a day and keep attracting thousands of users.


Mighty BF Games

BF Games is a modern game development studio that offers some of the most interesting online slots. With vibrant, colourful symbols, great visuals, exciting action, immersive soundtracks, and innovative bonus features, BF Games’ portfolio gives the most popular gaming themes a modern twist. Which casino slots have proven to be the most popular amongst our users?

Stunning Hot Slot

BF’s Stunning franchise remains a favourite go-to slot for experienced and new players alike, and we’re not surprised. The classic fruit theme is timeless, and despite its familiar symbols and simple gameplay, the Stunning Hot slot manages to blend the old with the new quite effectively. More modern visual effects and additional special bonus features make the gameplay more exciting than other fruit-themed casino slots and the optional gamble after each win may even double your reward. The other slots in this series: Stunning 27, Stunning Hot 20 Deluxe and Stunning Snow have all gained popularity, but Stunning Hot is one of those slot games which will stand the test of time.

Apart from Stunning Hot, other popular online fruit-themed slots have been developed by this game provider. In Fresh Fortune, BF Games have given the familiar fruit slot a refreshing twist. Taking place underwater, you’ll love the ice cubes and the fresh fruits bobbing on the screen; the water droplets on the fruits give the online slot such a fresh look.

With Royal Crown, they manage to give the fruit theme a Medieval twist, getting players to search for the precious bonus crown jewels in a fortified castle. Jewels World is another casino slot new players cannot miss. With a higher RTP than most other online slots - 98.05% to be exact, this slot has a lot of potential. The gold and treasure chest symbols are those you should be looking out for. What’s more, it’s fully mobile-compatible. You may even win 15 free bonus spins with a multiplier attached to every win

Book of Gods Slot

This Egyptian-themed Book of Gods slot allows you to travel back to the ancient Egyptian world to discover its most precious treasures. Its engaging graphics and soundtrack will take you through temples and pyramids in your quest for the mystical tome: the Horus book - the fabled book of the gods. The two-in-one scatter and wild symbol in this casino slot may even provide you with free spins! If Egyptian themes are your thing, we also recommend taking a look at Ramses Rising, a casino slot launched a year later by the same developer. You’ll find intriguing symbols in the form of feathers, scarabs, cobras and the eyes of Horus. Will you be able to unlock the treasures of the Pharaoh?


Book of Ming Slot

BF’s first Chinese-themed slot delivers great gameplay while providing stunning Oriental graphics. The dragons, Ming vases, the fabled Ming book… it’s everything new players would want to see in an Oriental-themed video slot. Finding the book of Ming should be your main objective, and the retriggerable free spins can help you reach this target. Definitely a successful slot by BF Games! Other Oriental-themed slots, aside from Book of Ming, include Dragon’s Power, Pagoda of Fortune and Koi Kingdom.

Wild Jack Slot

Fancy setting out on a wild west adventure? This Western-themed casino slot will have you bustling over golden horseshoes, revolvers and sheriff badges, but what you should be looking out for is Jack himself as the Wild bonus symbol.

Fibonacci Slot

If you’re on the search for more unique themes by BF Games, Fibonacci is a slot new players cannot miss. What’s in the name you might ask? Fibonacci is the name of an Italian mathematician who discovered what is now called nature’s golden ratio - whereby each number is the sum of the two preceding ones. Released in 2019, this casino slot offers a unique setup symbolising this specific sequence, and despite not having any bonus wilds or free spins, is still a very intriguing slot.

Powerful NetEnt Games

Swedish gaming giant NetEnt is another veteran video slot developer, having been operating for over 20 years now. Considered as one of the most popular gaming networks in Europe, it has thrived to become an unmistakable presence in this industry. Today, it handles tens of billions of gaming transactions per year, has over 1,000 employees around the world, and boasts a catalogue of over 200 slot games. Digital entertainment is their passion and their portfolio is packed with thrilling and epic slot games. If you’re more of an on the go player, new players may consider taking a look at NetEnt’s Touch Games series. This gaming giant created the first-ever mobile slot- the classic Gonzo’s Quest. Optimized for both iOS devices and Android, these touch slots can be played on both smartphones and tablets wherever you are, and you may even find special mobile-related bonuses on your first deposit!

Here are some of NetEnt’s popular releases which surely deserve a spin:

Starburst Slot/ Starburst Touch

Although several years have passed since the launch of this slot, Starburst is a classic which has remained a favourite amongst many online casino players. Still considered one of NetEnt’s biggest hits, Starburst is packed with enticing bonus features, such as the win both ways mechanic and expanding Wilds which may lead to generous payouts. Apart from the intriguing gameplay, the dazzling stars and mesmerizing jewels glistening on your screen will captivate all casino players. We can expect its popularity to persevere and stand the test of time.

Gonzo's Quest Slot

Another classic popular slot of this decade is Gonzo’s Quest! Venture into the Peruvian jungle with Gonzalo Pizzaro, a noted historical Spanish conquistador and have a go at finding the Eldorado - the lost city of Gold. The thematic graphics and sound effects all serve to get you in the mood for a mysterious expedition. NetEnt was also one of the first providers to feature avalanche/ cascading reels which enables the possibility of more than a single payout in a spin.

Wild Wild West: The Great Train Heist

If a Wild West adventure is your kind of fun, NetEnt has got you sorted. This Western slot is an immersive slot which is packed with bonus features! A free spins mode is activated with three or more scatters and a Wild Selector Wheel will render four different Wilds- a regular, expanding, multiplier and spreading Wild, which may increase your winning chances. Embedded in this slot is also a Pick and Click mini-game which is triggered by three bonus symbols on the reels. This will present you with three golden safes with a different prize in each.

Grand Spinn Superpot

Released in 2019, Grand Spinn Superpot is one of the latest NetEnt hits which has already won the favour of many casino players. This jackpot game has three possible jackpots to be won, including a progressive super jackpot, thus making it a better version of its predecessor - Grand Spinn slot. In contrast to classic jackpots where prizes are fixed, in a progressive jackpot, the payout increases while the user is playing the slot. This slot’s multiplier Wilds, and nudging bonus feature, promise big wins if you’re lucky and every spin can trigger a big jackpot. Featuring authentic vintage slots with bars and sevens, it contrasts to most other casino slots as it has only a single payline - just like traditional slots in land-based casinos. If the concept of a progressive jackpot sounds interesting, you can also consider other such casino slot games like Mega Fortune™ and Divine Fortune™.


Best Microgaming Slots

Microgaming, an Isle of Man-based game developer, is one of the trailblazers of the online gaming world, having been involved in online gaming since 1994. Its imaginative casino slots are loved by players all over the world, and its games are unique in their own way.

Bonanza Slot

Bonanza™ was one of the first casino slots to introduce the Megaways concept - a random reel modifier system invented by Big Time Gaming that allows any spin to produce a different number of symbols across the reels. Thus, this feature may increase your chances of hitting a winning streak. Full of unique bonus features and alluring visuals, Bonanza’s captivating graphics make it a lively slot not to be missed. A very unique feature is its mining carts. These may roll out precious symbols which you won’t find in the reels, and thus will help you activate the paylines. A free spins bonus game is also embedded within this slot!

Extra Chilli Slot

Following the same concept of Bonanza, Extra Chilli has also made a hit with many casino players. Powered by the Megaways mechanic described in the previous slot, it features a bonus horizontal reel which may carry special scatter symbols, increasing the number of ways you can win at this slot. Apart from its intriguing mechanics, it also features eye-catching graphics, especially the bustling marketplace in the background of the slot. Prepare to spice up your free time with Extra Chilli!

Who Wants to be a Millionaire™

Follow one of the world’s most famous TV shows on this online slot created by Microgaming! Also based on the Megaways system, you have higher chances of hitting a win. You can in fact win up to 50 free spins while you’re on the Hot Seat as well. It offers a venture which conveys the same excitement of being on a TV show.

Biggest Hits by Pragmatic Play

Pragmatic Play is another game development company which has graced our casino platform with innovative multi-award-winning slots loaded with bonus features. Here are some of its best slots:

John Hunter and the Tomb of the Scarab Queen

Embark on a series of adventures with the famed John Hunter to find lost Egyptian treasures. With a chance for free spins and a Money Collect bonus feature, hitting a win may be possible on a lucky day.

Wolf Gold

Here’s an animal-themed casino slot with a twist! Featuring spirit creatures which were worshipped by the Indians, you’ll definitely be eyeing the three possible bonus jackpots (Mini, Major and Mega), which may lead to bigger wins. If you’re a buff for animal themes, the recent slot The Dog House is another slot you should try out. Catch the four pure-bred dogs, which are the highest paying symbols, and stay alert for the dog house- which is the game’s Wild. A bonus mechanic you’ll definitely like is the sticky wilds feature. Ready to make some furry friends?

Mustang Gold

Another Wild West slot, by Pragmatic Play this time, is Mustang Gold. This casino slot is loaded with bonus features. It boasts unlimited re-triggers and a Money Collect Feature. The latter features golden horseshoes marked with random money values, which may trigger the Jackpot Reveal bonus game!

Pirate Gold

Who doesn’t love a good old pirate theme? Set out to sea and embark on your quest for the treasure chest! As soon as you hit eight treasure bags you’ll enter the bonus Respin Round which promises potential jackpots, multipliers and treasures!

Best Slots by Play’n Go

Play’N Go has become a leading game provider, creating only top quality casino slots and a bunch of great releases! As a global game-changer, new players can expect nothing but the best by these slot giants. Biggest slots by Play’N Go include the following:

Book of Dead Slot

One of the favourite Egyptian-themed slots by Play’N Go is definitely this slot here: Book of Dead. Travel back in time to ancient Egypt with the favourite slot explorer - the noted Egyptologist Rich Wilde, meet several Egyptian gods and hope to find the Book of Dead - which stands for both the Wild and Scatter bonus symbols. If you’re a jackpot fan, this is a casino slot which is worth a try! Go on another quest with Rich Wilde in the recent slot Rich Wilde and the Tome of Madness. Packed with bonus features, this slot offers cluster reels and several winning combos which may trigger a gripping bonus round. Who knows, you may even summon the Mega Wild!

Egyptian slots galore

Play N’ Go hasn’t stopped experimenting with the Egyptian theme after the success of Book of Dead, and has come up with several great hits: Encounter Egypt’s most legendary deities and personalities in Legacy of Egypt: Sekhmet, Sobek, Anubis, Ra, King Tut and Cleopatra. A Wheel of the Gods may even grant up to 20 free spins. In Doom of Egypt, you will be transported to the Egyptian underworld where you’ll be rewarded with free spins if you find the expanding symbols of immortality- the scarabs. Ankh of Anubis is given a sci-fi twist and is set in a futuristic Ancient Egypt. Apart from the great visuals, you can also trigger a bonus game and find a potential jackpot prize.

The Joker-themed slots by Play’N Go

The Joker series has made a hit amongst many players on EnergyCasino. From the very first Mystery Joker released in 2014 to Chronos Joker launched in 2019, this theme has brought one success after another. Each one is loaded with special bonus features, lots of wild symbols, multipliers, mystery spins and bonus rounds which promise big potential wins. Take a look at the Mystery Joker, Fire Joker, Mystery Joker 6000 (a modern twist to its classic version), Star Joker, Inferno Joker and Chronos Joker.

Here’s a quick look at some other popular hits on EnergyCasino:

Reactoonz Slot

This unique casino slot features unique and fun graphics and exciting alien action which gets even more intriguing with the series of bonuses this slot has to offer. From cascading symbols to Energy and Gargantoon Wilds and special Quantum bonus features (Alteration, Implosion, Demolition, Incision), your chances of winning are pretty good if you’re lucky. Don’t worry - each time a bonus is triggered, the name of the feature is announced, making it easier for you to grasp the underlying mechanics of this casino game.

Wild Frames

This is not the usual slot you’ll find, and its very uniqueness has made it a popular casino slot! You need clusters of five symbols for a win, and with every win, you’ll fill up the charge meter, according to the number of symbols in the winning cluster. When the meter is full, you’ll be able to unlock bonus features. Upon hitting 80 charges, you’ll also trigger the game’s Wild Frame- whereby all symbols within the frame would be transformed into Wilds.

Rise of the Olympus

Are you up for an adventure with the gods? In this slot, Hades, Zeus and Poseidon are each endowed with a singular power. Hades destroys non-winning symbols, Poseidon offers more bonus wilds and Zeus transforms symbols to help create more winning combinations.

Responsible Gambling

  • Take advantage of any no deposit bonuses you can acquire.
  • Play the free demo versions: This will help you understand the slot’s bonus features better, helping you bet more responsibly and enjoy the casino game more.
  • Remember, it’s totally random: There’s no actual strategy you can adopt to ensure a winning streak while playing casino slots online; it all depends on luck.
  • Enjoy the game! Playing online slots should primarily be done for fun!


Before proceeding to play online, make sure you go through the Terms & Conditions to learn about how bets and paylines work and any minimum deposit you need to place before you start playing. Gambling is risky, and you should never depend on this activity as a source of income. Play responsibly and stay alert while gambling! Visit the EnergyCasino site today to get a welcome bonus and start playing slots. Good luck, and have fun!


⭐ What are the best online slots to play?

Most online slots employ the same slot mechanisms and rules, and, therefore, the probability of winning is primarily based on luck and not on the game itself. Although the return to player rate and the number of paylines may make a slight difference in your potential payout, there is no significant effect on the winning probability.

⭐ When is the best time to play online slots?

We recommend you only play online slots when you have some free time and money you can afford - and have budgeted - to lose. If you stick within your budget, playing online slots will be more fun, and the risks of this activity becoming a financial burden will be much lower.

⭐ Which online slots’ payout is best?

To determine the payout of each casino slot, you must look at the RTP percentage, which would usually be found in the information section of each slot. However, do keep in mind that this percentage is calculated on thousands of slot games, so the actual probability of winning is not equal to the slot’s RTP.

⭐ Which are the best free online slots?

Online slots can be enjoyed without risking a wager! Log in to your EnergyCasino account and search for the best slot you’d like to play. Hover over the thumbnail of the game until you see a grey DEMO button, click and enjoy the free DEMO version of any slot which sparks your interest. Depending on your jurisdiction, you may be asked to register and complete the verification process in order to access the DEMOs. In cases where verification is not necessary, you may be able to play as a visitor.

⭐ Which is the best online slots site?

EnergyCasino is one of the world’s fastest-growing online casinos, where you can find an extensive range of slots from different game providers. Each player will benefit from a welcome bonus, first deposit bonuses, various promotions (dependent on geographical location) and a fast payout system to guarantee an excellent casino experience from start to finish.

⭐ Can you win money playing online slots?

When you are ready to raise the stakes, you can place real money wagers on any game of your choice at EnergyCasino. All you have to do is log in to your Energy account, search for any slot, and get ready to spin! Winning symbol combinations pay a multiplier on the amount you wager; thus, the amount you win is directly proportional to your wager. For example, if you bet €1 and win 5x your bet, you will receive €5. If you bet €10, you will receive €50. As with all casino games and betting as a whole, there is no fail-safe strategy, so we encourage you to play responsibly.
