Top 30 Online Slots All Time

Check out our mega top slots guide below, created especially for all online slots fans!

Since 2001 we have been playing and testing thousands of slot machines online. So we decided it was time to make an all-time top list with the 30 best.

After much deliberation, we have narrowed down a list of the best 30 online slots ever made. But we didn’t want to leave you with only a slot name title. So we have added a short description of each slot machine. In our opinion, all the below deserve their ‘Top 30’ status.

It took a lot of work to make the top list below. It was one of the most challenging tasks since we started OnlineCasinos.net. Because there are so many good slots online, it was also challenging to cut the top list of nominees down to only 30. So in the future, we will extend the list to 50 as we had to leave some excellent slot games out. Furthermore, many new slots are also released each month.

All the games below you can also play on your Android, Windows, and iOS mobile devices.

13. Gonzo’s Quest

Gonzos Quest Slot Machine Rank 11

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

The Gonzo’s Quest slot machine launched in 2010, the 20-pay line slot carries an RTP of 96.00%, and it has cascading reels, which means the symbols all fall into place from above. When wins are created, those winning symbols will disappear, and more symbols from above will fall into the spaces that were vacated.

Gonzos Quest Slot Ranked 11 Bonus Game

That cascading feature can bring in multiple payouts after each spin as the new symbols drop into place, but there are also multipliers that 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.

However, it doesn’t end there as six other bonus rounds can occur randomly during any spin when the ‘Ted’ character wakes up from his sleep to give you the potential for some handsome payouts.

Pink Elephants appears on this list as one of Tunderkick’s best releases. It has become surprisingly popular, and that popularity is probably down to several reasons. One of those reasons is that this is a 5-reel slot with 4,096 ways to win.

Furthermore, Pink Elephants has a medium to high variance and a jackpot of 820,000 on offer. We all like the idea of having the potential to win amounts that have to be considered life-changing, and that’s what the Pink Elephants slot machine has the potential to do.

A good number of game features will also be a factor in the popularity of this 96.1% RTP slot as there are lucrative free spins rounds and wild symbols and scatter symbols for players to take advantage of.

We feel that this slot machine will be popular for quite some time, and for that reason, we feel it deserves to be placed on this list.

30. Theme Park Tickets of Fortune

Theme Park Slot Machine Rank 28

Theme Park Tickets of Fortune by NetEnt is one of those online slots that we feel is underrated and does not get the credit it deserves. Released in 2016, this 5-reel, 25-payline slot has a lot going for it and is a slot machine game that we find highly enjoyable.

Why is it so enjoyable? Due to many bonus features that can be found present in the slot. For example, there are six mini-games, stacked wilds, and a fun Claw feature.

Couple those excellent features with HD graphics and animations that work seamlessly regardless of your device. Then you have an online slot that looks great and provides endless hours of fun.

Theme Park is a low variance slot. That means regular payouts, and it has an RTP of 96.52%. So this makes it an excellent choice for those with limited budgets who want to enjoy some long-paced action at online casinos.

31. Hong Kong Tower

Hong Kong Slot Machine Play View

Hong Kong Tower is an online slot released in 2017. Some players have claimed that it was one of the best releases of 2017. Created by ELK Studios, this aesthetically beautiful 99-payline slot was designed in a mobile-first manner, and it looks fantastic no matter what device you are using to play it.

Another big reason for its popularity is, no doubt, the big jackpot of 300,000 dollars/euros that is on offer if you bet the maximum spin amount. That is huge for a local jackpot and is essentially 3,106x the total spin bet. So it is not strange that so many players like this fun online slot.

Hong Kong Tower does not let you down with its features either. The game is a 96.30% medium variance slot has stacked symbols, wild symbols, scatter symbols, and its main bonus feature, the Wheels of the Sky. Admittedly, a lack of free spins is a little disappointing at first, but these features more than make up for it.

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. That would be $19,948,498.72 if you were playing in dollars. The jackpot was won by Englishman Jon Heywood back in 2015.

Which Slot Developer Has the Best Games?

The leader of the best online slots provider is still, for now, Netent. I would have hoped I could have added some more Microgaming slots to this ‘Top 30’ list. But unfortunately, it seems Microgaming has for some years forgotten how to make great, UNIQUE, exciting slot games. However, this has recently changed, and now in 2022, Microgaming has signed deals with 12 independent game developer studios. These studios are to create new exciting slot games for them. You can read more about this here.

Admittedly, Microgaming has introduced some excellent new concepts over the last few years, including the none-payline 243 Ways to Win slot. Microgaming even shared the 243-Ways concept, so developers like Net Entertainment could release their slots using the no-payline idea.

Coming in second, just being clipped by NetEntertainment, is Elk Studio. They now have the 2 top spots on our all-time top list with the Wild Toro 2 Slot and Nitropolis 3.

This up-and-coming developer has surprised us positively with the unique, exciting games they have made. I hope Elk Studio keeps up the great work. Having new slot developers like Elk Studios releasing new games with a different dimension to every one of their latest slots is a breath of fresh air.

It also shows that Elk Studios have taken the competition seriously. The company has realized that every new release needs to be as unique as the last slot for its games to stand out in a competitive online slot machine industry. Well done, Elk Studios!

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.

Last but not least

Yggdrasil Gaming and Pragmatic are high-quality online slot makers. They create some of the best slot machines online. Furthermore, many of the games they make are highly volatile slots, which means less often wins, but chances of big payouts. For example, pragmatic’s The Dog House Megaways Slot is one of their top highly volatile slot games. And for Yggdrasil Gaming, the game Age of Asgard, both listed in the top 5 above and is definitely worth a try.
