10 Most Popular Slot Games of All Time

There are thousands of online pokies and you can explore hundreds of them on any given online casino. But with so many games available, how do you know which ones are most deserving of your time?

In this guide, we’ll tell you, as we look at the top 10 online slot games from our reviewed operators.

10. Rainbow Riches

Created by Barcrest, Rainbow Riches is one of the most popular slots games around and has featured in thousands of online casinos and land-based casinos. It has also helped to inspire many other games themed around Ireland and leprechauns.

These copycat pokies didn’t just borrow the aesthetic, they also copied the game’s features, including the famous Trail feature, where players are tasked with traversing a long course filled with prizes.

These days, Barcrest is owned by Scientific Gaming (SG), a brand that also controls the rights to WMS and games like Ruby Slippers.

9. Age of the Gods

The Age of the Gods game is the flagship pokie for Playtech’s biggest progressive jackpot system. This progressive jackpot system was once tied to Playtech’s marvel superhero games, but when those rights expired the owners refused to extend them.

As a result, Playtech switched all games from Marvel superheroes to Greek gods, keeping the titles and the jackpots alive. This series of pokies is one of the most popular slots games around and has attracted countless plays over the years, with many of those being on the original Age of the Gods pokie.

8. Game of Thrones

Game of Thrones was a phenomenon, one of the most popular TV shows in history and one that was watched in dozens of countries by hundreds of millions of people. It’s no surprise then, that this pokie became one of the most popular slots games released by Microgaming.

The Game of Thrones video pokie doesn’t use any images or video from the TV show, but it does have a license to use many of the show’s logos, flags, and sounds, and this helps to create a unique gaming experience that fans of Westeros are sure to enjoy.

7. The Dark Knight

The Dark Knight is a progressive jackpot pokie created by Microgaming. It is based on the film of the same name, which became a massive box office hit back in 2008. And just like the film on which it is based, the Dark Knight pokie was proceeded by the Dark Knight Rises, which features Bane and includes a bonus where Bane and Batman fight on the reels.

Fans of the Caped Crusader will get a kick out of this dark and exciting creation, and pokie aficionados will also be happy to know that there are many big features and payouts.

6. Cleopatra

Although simple, the Cleopatra pokie was hugely popular when it was first released and has since earned a reputation as one of the most popular slots casino games ever. In fact, it helped to spawn the current generation of Egyptian-themed titles, including Book of Ra and Book of Dead, both of which are almost as popular and utilize many of the same features as styles as this timeless creation.

Cleopatra is simple, and it doesn’t have the grand graphics or features found on similar pokies, but if you’re looking for a true real money pokie classic, look no further.

5. Monopoly

Monopoly is one of the biggest game licenses in the real money gambling sector, and it’s easy to see why. This game is huge, with generations of support and a reputation as one of the best board games ever.

Everything that makes Monopoly such a popular board game works wonderfully in a real money pokie format, which is why this title spawned several sequels, each offering something a little extra.

4. Gonzo’s Quest

Gonzo’s Quest is a NetEnt classic that uses the Avalanche game mechanic, a chain reaction mechanic with a built-in multiplier that adds an extra layer of depth. It’s a funny, quirky, and stylish pokie, and it’s one that has won countless praise from players and reviewers alike.

The star of the show is a Conquistador on a hunt for treasure. He’s actually based on a real Conquistador, one who desperately searched for El Dorado, but didn’t have any luck. Players are tasked with trying to rewrite history as they search for their own city of gold.

3. Starburst

Cleopatra isn’t the only pokie to go back to basics and still achieve huge success. Starburst, one of the first NetEnt games to go global, is very similar in that sense.

Starburst takes place in outer space, with a simple black backdrop and symbols that include planets, gems, and other brightly colored visuals. There are no 3D graphics and there are no grand bonus features, either. It’s simple, but it’s also fluid, fast, and compatible with a host of devices, and it provided these features long before other pokies did.

As a result of this, and the fact that it has a high RTP and was heavily promoted, Starburst quickly became one of the industry’s most popular slots games, a title that it has held onto over the years.

2. Mega Fortune

NetEnt’s biggest progressive jackpot game gives players a taste of the high life, with flash cars, private jets, Champagne, and all the other finery associated with the life of a jet-setting millionaire.

The great thing about this game is that all of those luxuries can become a reality if you scoop the jackpot. It’s possible to win sums of money in excess of $10 million playing this game, and every player can win this amount with every spin they take.

In fact, many previous winners have scooped 8-figure sums with bets of less than $1, something that few other pokies can provide.

1. Mega Moolah

Mega Moolah is one of the most popular slots games in the world. It has smashed countless records for the biggest pokie jackpots, and on two previous occasions, it has paid jackpots in excess of NZD 25 million!

Despite its cash-oriented name and monstrous jackpot, Mega Moolah is an animal-themed pokie and takes place on an African Safari. The reels are filled with wild animals, including lions, zebras, giraffe, and monkeys, the latter of which serves as the game’s bonus symbol

The beauty of Mega Moolah is that you don’t need to bet big to stand a chance of winning the jackpot. Every player and every spin can win, but when you increase your stake you also increase your chances of winning. This is why it has consistently been ranked as one of the top 10 online slot games in the world and why it will likely remain on this list for many years to come.
