Why do we believe this is the most accurate Top 30 Slots Guide Ever?

Top 30 Online Slots

1. Gates of Olympus™ Slot (Pragmatic Play)

RTP: 96.50%

Reels: 6

Rows:5

Pay Lines: 8 Same Symbols

Free Spins: Yes

Special Feature: Tumble Feature, Buy Bonus

Max Bet Win: 5000x

Fun to Play Score: 10 out of 10

As an online slot enthusiast and veteran with over 20 years of spinning reels, ‘Gates of Olympus™’ by Pragmatic Play has consistently grabbed my and many players’ attention.  It is currently, and has for some time, been one of the most popular online slots.

This slot game’s popularity isn’t surprising, considering its unique features, engaging gameplay, and the allure of Greek mythology wrapped in a digital package. Let me explain why we believe this slot is a must-try for every passionate player and deserves a top 3 spot.

The first thing that strikes you about Gates of Olympus is its stunning aesthetics. Set in the mythical Mount Olympus, home to the Greek Gods, the game is visually striking. The detailed graphics and a captivating soundtrack instantly transport you to another world, setting the stage for an immersive gaming experience. The design of Zeus, the game’s central character, is captivating and adds a touch of authenticity to the game’s mythical theme.

Now, let’s move to the core of any slot game – the mechanics. Gates of Olympus is a 6-reel slot with an ‘All Ways’ pay system, offering a staggering 20,704 ways to win. So this alone piques the interest of many players, as it promises numerous possibilities for striking a winning combination. The game’s volatility is high, paired with a return to player (RTP) of 96.5%, indicating the potential for some genuinely divine payouts.

What truly sets Gates of Olympus™ apart is its unique and exciting bonus features. The Multiplier feature is personified by Zeus, who occasionally throws multipliers onto the reels, which can significantly boost your winnings.

The Free Spins feature is another high point, triggered by landing four or more scatter symbols. This feature starts with 15 free spins, with the potential for even more retriggered spins and multipliers, leading to some potentially enormous wins.

The Ante Bet feature is yet another innovation that adds an extra layer of thrill to the game. By doubling your bet, you increase the chance of triggering Free Spins, giving you more control over the gameplay and adding a strategic element rarely seen in slot games.

Finally, the sheer unpredictability of the game is a huge draw for many players. With each spin, you never quite know what’s coming, and this suspense keeps you on the edge of your seat. The excitement is palpable when Zeus throws a multiplier onto the board or when you land on a scatter symbol and trigger free spins.

Gates of Olympus™ isn’t just another slot game. It’s an adventurous journey into a mythical world filled with big
wins, stunning graphics, and unique features. Its popularity among slot enthusiasts is a testament to its engaging gameplay and massive winning potential. So, whether you’re new to online slots or a seasoned player, Gates of Olympus is a game that deserves a spin. You never know – you might have the gods on your side on the best online slot ever!

2.Sweet Bonanza™ (Pragmatic Play)

RTP: 96.48%

Reels: 6

Rows:5

Pay Lines: 8 Same Symbols

Free Spins: Yes

Special Feature: Tumble Feature, Buy Bonus

Max Bet Win: 21175x

Fun to Play Score: 10 out of 10

As an online slot player who plays daily, I’ve been around the block a few times when spinning those digital reels. Over the years, I’ve tried my hand at thousands of slot machines, from the old classics to the newest releases. And one that continues to stand out for me is Pragmatic Play’s, Sweet Bonanza™.

First off, Sweet Bonanza plays differently than your typical slot. It uses a Tumble Feature, which means the reels don’t spin in the traditional sense. Instead, symbols fall from the top, and when you hit a winning combination, those symbols disappear, allowing new ones to tumble down into their place. It’s a mechanic that always keeps every spin exciting.

The overall design and aesthetics of Sweet Bonanza are a big part of its appeal. It’s like entering a virtual candy land with vibrant colours and beautifully rendered sweets and fruits. It’s not just about looks, though. The sound design is on point, too, enhancing the overall experience and making it a delight for the senses.

However, one of the main reasons I keep coming back to Sweet Bonanza is its high volatility. Yes, it can be a roller coaster ride with wins not always coming on every spin. But when those wins come, especially in the bonus game’s free spins, they can be substantial. It’s this balance of risk and reward that makes the game so thrilling.
When it comes to features, Sweet Bonanza™ doesn’t disappoint.

The Free Spins round, triggered by landing scatter symbols, is where the game really comes into its own. During these rounds, you can rack up wins without touching your stake, and there are also multipliers on offer that can seriously boost your winnings. It’s a rush that only a few online slots can give you when you hit a big multiplier. When it comes to features, Sweet Bonanza doesn’t disappoint.

Let’s not forget about the maximum payout potential. You do not see the chance to win up to 21,175x your stake in every slot. This big win potential keeps players like me coming back for more.

Finally, I have to mention the Buy Feature. You can buy your way directly into the Free Spins round in Sweet Bonanza. It’s an excellent feature for those times when you can’t wait to get to the bonus action. But remember, this comes at a cost, so use it wisely.

That’s my take on Sweet Bonanza, a slot that’s keps me entertained for countless hours. While it is one of the most popular slots in 2023, it may not be for everyone. However, its unique gameplay and features make it stand out in online slots. But as always, remember to gamble responsibly. Happy spinning on this top game!

3. Starburst™ (Netent)

The 5th slot game on the top list is the all-time most popular online slot. The Starburst game is always busy at online casinos. Starburst™ by NetEnt is a fantastic 5-reel, 20-pay line video slot with an RTP of 96.09% and wins payout both ways. Most of its popularity is down to its easy play and low variance, which means regular payouts and plenty of entertaining action

RTP: 96.09%

Reels: 5

Pay Lines: 10 Both Ways

Free Spins: No

Special Feature: Respin

Max Bet Win: 500x

Fun to Play Score: 10 out of 10

Starburst has been designed with a classic feel but with stunning graphics, and its popular bonus feature is that of the expanding wilds. These can land on any of the 5 reels, and when they do, they will expand to fill the entire reel. Not only that, when these expanding wilds land, they will lock the reels they landed on. You will then win free re-spins on the remaining reels, where any new winning combos will pay out accordingly. Furthermore, the expanding wilds can be retriggered up to three times in a row, giving you chances of massive payouts.

4. The Dog House® Megaways (Pragmatic Play)

RTP: 96.55%

Reels: 6

Rows:7

Pay Lines: Up to 117649

Free Spins: Yes

Special Feature: Megaways, Sticky Wilds With Multipliers, Buy Bonus

Max Bet Win: 12000x

Fun to Play Score: 10 out of 10

Pragmatic has released several great online slots lately, bringing many loyal players. One of the best ones, undoubtedly, is The Dog House Megaways Slot.

With 6 reels, 7 rows and 117,649 ways to win, this slot can produce payouts of over 12,000 times the total stake. So there is enormous payout potential, especially in the free spins, where wilds become sticky wilds.

So the exciting free spins game is why many players love playing The Dog House Megaways.

To trigger the free spin feature, you need to land 3-6 Scatters on the reels, or you can use the Buy Bonus button for a price of 100 times the total stake. Depending on the number of Scatters you get, you are rewarded 7 to 20 free spins with up to 7 Sticky Wilds on each reel.

If you choose the Raining Wilds feature, you can win up to 30 free spins with up to 6 Wilds on each spin, but wilds are not sticky. The best part of the free spin feature is that the Wilds can come with an attached x2 or x3 Win Multiplier.

When we play The Dog House Megaways, we always choose the free spins with sticky wilds, and if it pays a big win, we choose the 30 free next time.

The Dog House Megaways is real fun and exciting online slot with many fans, and it deserves a 6th spot on the 30 best online slots list.

This feature gives players more opportunities to form winning combinations and significantly boosts the game’s thrill factor.

Medium/High Volatility and Winning Potential

As a medium/high-volatility slot, Viking Fury Spinfinity appeals to many players, especially thrill-seeking players looking for significant wins. It might not pay out as frequently as low-volatility slots, but the wins can be substantial when it does. With a maximum win potential of up to 50,000x your stake, it’s clear why players are drawn to this high-seas adventure.

Free Spins Average is 1 in 470

Max Win: $/€282,646 or 50,000x your stake

Finally, Viking Fury Spinfinity scores top ponts for its accessibility. Blueprint Gaming has optimized the game for mobile devices without compromising the quality of graphics or smoothness of gameplay.

The free spins bonus is unique as it revolves around Sticky Wilds and multipliers up to 10 on each wild, increasing on every free spin—like The Dog House slot but with an increasing multiplier on wilds each spin.

There is also a Mad Respins Feature, triggered by the Paw symbols, where mystery symbols can reveal a symbol from the paytable or cash symbols for potential rewards.

The game’s high volatility may not be favorable to some players, and the feature buy could deter low-roller players.

1. 1. Toro Goes Berserk when the Bull and the Matador symbols land in the same spin. Toro will knock all Matadors off the reels, leaving a trail of Wilds behind him.
   2. Land the Silver or Gold Matadors to trigger the Matadors Re-spin feature. The win multiplier attached to the Gold Matador increases with every re-spin.
   3. When Toro knocks out a Gold Matador, the Matador Knockout feature is triggered. The multiplier value is transferred to Toro, and he becomes a Walking Multiplier Wild.
   4.  Land a Matador symbol on the screen to trigger the Expanding Reels Feature. An extra row shows up on top of the reels, increasing the overall number of winning paylines.

Why not play the best-paying online slot machine with an impressive 99% RTP.

Book of 99 is a new excellent slot release by Relax Gaming, and this Greek-themed slot game will allow you to explore the deepest mysteries of the tombs as you go on a quest for treasures.

Once you access the game, you will spot a grid that contains 5 reels and 3 rows. Book of 99 is fully optimized for mobile and desktop use, which means you can also enjoy it on any Android and iOS device.

The most prominent feature that Book of 99 has is its Return To Player. The RTP rate of this slot is 99%, which is quite astonishing. Not only that, but it does have a few fun bonus features.

The first feature is the Free Spins feature, in which you will win 10 Free Spins if you land at least 3 Scatter symbols. The free spins can retrigger. Before the free spins start, you get a random symbol that expands during the free spins.

There is one more way you can win the free spins, the Wild symbol in the Book of 99 has two purposes. First, it can replace regular symbols but also fills up the Collection meter. Each time a Wild is landed, the Collection meter increases by 1 step. The Free Spins feature is also triggered when the meter hits 99. 

When playing the game, it is nice to know you will win free spins when it hits 99 because most of us have tried waiting too long for 3 Scatter symbol to appear on a slot game.

Book of 99 has 9 fixed paylines, and you can bet between a minimum of $/£0.10 and a maximum of $/£100. Once you’ve set the bet, all left is to spin the wheel. I have played this online slot machine a lot, and it pays back a lot more than other online slots. Book of 99 will become a player’s favourite.

A firm favourite among high-rollers, Jack and the Beanstalk, is an older online slot still going strong at online casinos. Popular due to a very high variance, which means a longer time between payouts, which is usually huge when they arrive.

Fun to Play Score: 9 out of 10

If you were to ask any players that have been playing online slots frequently for years to name 20 of the best slots of all time, we would bet that most would name Gonzo’s Quest by NetEnt among them.

The Gonzo’s Quest slot machine launched in 2010, the 20-pay line slot carries an RTP of 95.97%, and it has cascading reels, which means the symbols all fall into place from above. So on every win, those winning symbols will disappear, and more symbols from above will fall into the vacated spaces.

That cascading feature can bring in multiple payouts after each spin as the new symbols drop into place, but some multipliers are attached to the rewards above the reels. After each consecutive win due to the cascading tiles, this multiplier increases by one, which means there is some good potential for big wins. Other bonus features on Gonzo’s Quest include free spins, wild symbols, and scatter symbols.

Ted is another popular online slot that has hit online casinos in the last few years, and there is an apparent reason why it is so popular. It’s Bonus rounds – probably the most we have ever seen in an online slot.

With an RTP of 95.81% and a low to medium variance, you can expect fast-paced action on this 5-reel, 20-pay line online slot, and you will soon see that there is never a dull moment when playing.

You will see five unlockable bonus rounds when you land three scatter symbols on your reels. Every time you unlock one of the bonus round, you automatically move up to the next one.

Almost anyone who has played online slots for an extended period will have heard of Mega Moolah or played it. This legendary progressive slot by Microgaming is so well known for its ability to pay out massive sums of money that it is fittingly known as the ‘millionaire maker’ at online casinos.

Having been around since 2008, Mega Moolah actually holds the record for the single largest payout ever won on an online slot. That magic number was a staggering 17,879,645 euros.

How we Rate Online Slots

Which Slot Developer Has the Best Games?

OnlineCasinos.net now exclusively utilizes our Smart Rating system to assess each online slot machine in our top 30 list. This has led to some adjustments in the slot rankings, notably elevating many Pragmatic slots higher up the list. Pragmatic now holds the top two spots for the best slot games, surpassing Elk Studio, previously in the lead. However, due to the RTP of only 95%, Nitropolis 3 from Elk Studio has been shifted down to the 10th spot. There is no doubt Elk Studio makes some of the best games, but to rank in the top 3, they need to offer at least around 96%, which is the industry average for online slots, to satisfy us.

Pragmatic slots have consistently stood out in recent years for their high-quality, inventive, and thrilling slot games. Notably, they have become the most popular choice in casinos, featuring titles like Sweet Bonanza, Gates of Olympus, and Sugar Rush.

Many of Pragmatic’s slot games are characterized by high volatility, offering fewer frequent wins but the potential for substantial payouts. One example is Pragmatic’s The Dog House Megaways Slot, showcasing their prowess in developing highly volatile and quality slot games.

In the past six months, another notable game provider that has gained prominence in our top 30 list is Games Global (Including Microgaming Portfolio), with two new video slots securing spots in the Top 10.

Games Global has expanded its influence, with 37 independent game developer studios contributing to their slot portfolio. Several of these studios have produced outstanding slot games, marking a resurgence for Games Global as one of the top game providers in 2023. The industry is witnessing the fruition of its efforts, with Games Global releasing high-quality slots that have solidified its position among the leading game providers.

We decided to make some changes on who makes the best slot games online before we had Netent as the number one game developer. However, we all agree here at OnlineCasinos.net that someone else deserves the spot more, and that’s Pragmatic.

Play’N Go

These slots have always been one of my and many others’ favourite slot providers, and they make some of the best online slots out there. Moreover, they never seem to disappoint, releasing at least 1 to 3 of the best-released slot machines each year.

Thunderkick

They are also keeping up, but this slot developer is still not entirely up to the mark of Microgaming. Thunderkick is one of the newer developers on the scene, only breaking into the online slots industry in 2012 with some remarkably different slots.

The diversity Thunderkick has added to the diverse array of online slots available is nothing short of brilliant. The company entered the slots industry with some daring slots that were relatively simple in design. However, Canadian and UK players loved the simplicity and took Thunderkick slots like a duck to water.

Their fast-paced, action-packed themes have turned heads of the company’s inauguration into the online slots world. So keep your eyes peeled for more online and mobile slots from this developer because things can only get better.

Relax Gaming

Relax Gaming really impressed us last year, coming up in 2022 with some unique designs and highly entertaining slots like the Snake Arena and 4 Secret Pyramids slot machine. We can’t wait to see the games they launch in the rest of 2023.

Last but not least

Yggdrasil Gaming is a high-quality online slot maker. They create some of the best slot machines online. Furthermore, many of the games they make have a unique style and gameplay; for example, the excellent the game Age of Asgard, listed in the top 10 above and is definitely worth a try.
