Online casinos have known an incredible growth the past few years. It’s not a surprise, seeing how good they all are. You can play just like in a land-based casino from your desktop, your couch or even your bed. What’s not to like about this? This is especially thanks to the incredible amount of slot machines you can play on that online casinos are getting even more popular.
There are thousands of online slot machines ready to be played 24/7 on the best online casinos. Some of them are themed on Ancient Egypt, while others are about Vampires, Ireland, Mythology or even Wild West. It is nearly impossible to get bored when playing online casino, thanks to all the various games it offers. There are slot machines, but also live casino games (Blackjack, Poker, Crazy Time, Mega Ball…), original games (Hi-Lo, Mines, Plinko…), video poker, and even sports and esports betting.
How we picked these 10 slot machines
We tried to establish the most neutral and objective selection. In order to be a part of this selection, a slot machine has to check multiple criteria. It has to be:
Featured on multiple casino’s Popular page
To determine whether a slot machine is popular among players, it has to be featured on at least five casinos’ popular page. A lot of online casinos have this kind of page, where you can check what are the most popular games of the moment. This page is usually there to help players who are in lack in inspiration when it comes to trying out new slot machines.
We based this selection on our partner casinos. All these casinos are trusted and feature an extensive selection of slot machines from various game providers.
Older than six months old
In this selection, we do not want games that were released less than six months ago. Why? Because when games are new, they can be a fad. This is not a selection of the most trending games, but a selection of the best games of all time. Setting an “age limit” is thus an acceptable solution to establish a ranking of the most popular slot machines of all time.
If a game is at least six months old, and is on multiple casino’s popular page, it is eligible to be in this selection. But there is one more criterion.
Free from any ongoing promotion
Finally comes the last criterion to build this list of popular slot machines. There has to be no ongoing promotion on this game, such as a tournament or a special event. If there were, there would be no way to tell if the game is popular by itself or because of the current event.

The 10 most popular online slot machines ever
There we are. You are about to discover which slot machines are the most popular ever. If you are an avid online casino player, you probably have played on most (if not all) of these slot machines. If not, what are you waiting for?
These slot machines are in no particular order. Enough talking, let’s discover which games players like the most.
Rich Wilde and the Book of Dead (Play’n GO)
Book of Dead is a quite old slot machine, but it is far from being outdated. It is in fact the most popular slot machine around the world, and it has been for quite some time now. Its popularity is due to two things. The first one is that this game design is timeless. It came out in January 2016 and yet its design still looks fresh! The second reason why this game is popular is thanks to how easy it is to play and understand it. It’s a classic slot machine from the “book family” with 3 scatters that trigger free spins with a special paying symbol. You can win up to 5,000 times your bet on this game.
Sweet Bonanza (Pragmatic Play)
Sweet Bonanza is an online casino game that was released on June 25 2019 by Pragmatic Play. It is the most played slot machine of this great casino games provider. It features fruits, just like a classic slot machine, but it is far from being classic. To enter into the free spins feature, you need to have four lollipops on the reels. Every spin from the bonus round can be boosted by one or various sugar bombs. These bombs are of random values going from 2x to 100x. Only the current spin gets multiplied. The multiplier gets reset between every spin.
The Dog House Megaways (Pragmatic Play)
You enjoy playing on Dog House from Pragmatic Play? We are sure you will like playing on Dog House Megaways even more. It’s like Dog House but on steroids thanks to Big Time Gaming’s Megaways feature. This feature allows this game to have between 64 to 117,649 paylines. Get three dog paw prints to land on the reels and you will unlock the free spins. You can choose between two bonuses: sticky wilds or raining wilds. The sticky wilds bonus is the most volatile. During this bonus, dog houses are sticky wilds with random multipliers (1x, 2x, 3x).
What you want in order to hit a big win is to have 2x or 3x wilds on reels 2 to 5, with a maximum of Megaways and premium symbols on the first and last reels. This game is really exciting to play, and you can even buy the bonus feature if you don’t want to wait.
Legacy of Dead (Play’n GO)
Book of Dead is a great Play’n GO slot machine, and so is Legacy of Dead. It is actually its sequel and it has the same maximum potential win of 5,000 times your stake. The major difference resides in its bonus feature. When 3 scatters land during free spins, you not only receive more free spins, but you also get an additional paying symbol. There are up to 9 symbols you can unlock: 5 classic symbols, and 4 premium symbols.
Razor Shark (Push Gaming)
After Play’n GO and Pragmatic Play, it is now time for a Push Gaming slot machine to be part of this selection. This studio has not released a lot of games, but all of them are high quality. The one that is featured in this selection is Razor Shark. It was released in August 2019. This extremely volatile slot machine has no maximum win. When seaweed lands on the reels, it activates the Mystery Stacks feature. It can reveal either matching symbols, or Golden Shark Coins. These coins can multiply your bet per 1, 2, 5, 10, 25, 50, 100, 1000 or 2500. The free spins last as long as you have seaweed on the screen. After every spin, the global multiplier increases. Imagine getting a 2,500x coin with a 8x multiplier? This slot machine really has a huge potential.
Book of Sun Multichance (Booongo)
If you like playing on Book of Dead and Legacy of Dead, there is not reason for you not to like Book of Sun Multichance. Like its name says it, this slot machine is also from the book family. It can be compared to Legacy of Dead, because you also receive an additional symbol for every retrigger you get during the free spins. This game is even more exciting because its maximum payout is not 5,000 but 10,000 times your bet.
Deadwood (Nolimit City)
Deadwood is a highly popular Nolimit City slot machine. It was released in May 2020 and was immediately adopted by players from all around the world. It features two different bonuses: one that triggers with scatters only, and one when you get two sheriff badges with your scatters. The best one is the latter, of course, as the multiplier keeps increasing for every banner you get during the free spins. This game is extremely popular for one very good reason: its high volatility. In fact, you can win up to 13,950 times your bet on this very slot machine.
Starburst is one of NetEnt’s most popular slot machine. It was released almost 10 years ago, in 2012, and it is far from being outdated. Although its design and global interface seem a bit simple, it has a very interesting gameplay. There are no free spins on this slot machine, but a respin feature. Every time a wild (star) lands on reel 2, 3 or 4, it stays in place and you get a free respin. You can respin up to three times, as long as you get more wilds in the three middle reels. This slot machine has an incredible maximum payout of 50,000 times your bet.
Bonanza (Big Time Gaming)
Bonanza is one of Big Time Gaming’s most popular slot machine. This game demonstrates the Megaways feature in one of the best ways possible. The Megaways feature is a creation from this game studio. Bonanza is a 6 reel slot machine with up to 117,649 Megaways that promises its players a maximum win of 10,000 time their bet. When getting four scatters (the letters G, O, L and D) you are awarded 12 free spins with an increasing multiplier.
Gonzo’s Quest Megaways (Red Tiger)
Last in this selection comes Gonzo’s Quest Megaways. This is NetEnt’s most popular slot machine. After this studio was bought off by Evolution in 2020, it was even declined into a Live casino game known as Gonzo’s Treasure Hunt. This is a cascading reels slot machine. Every winning symbols disappear and leave the place for other symbols to come into the screen. Doing so, the multiplier you can see on the top right increases by one. At the third retrigger, it increases by two, reaching the maximum multiplier of 5x. During free spins, this win multiplier can get up to 15x. The maximum win on this slot machine is 20,000 times your bet.
New slot machines are being released every single week but the oldest ones are still being played a lot. Today, we are taking a look at some of the most popular slot machines around the world.
