How We Review the Casinos

Before we recommend any website, we test it and carry out stringent tests on a variety of important factors.

We know that you want a great selection of titles, including online slot machines with the best payouts, progressive jackpot slots, classic slots, video slots and more. We also look to see if they have other table games on offer, including poker, blackjack and roulette, for when you fancy a break from the reels.

Excellent security and reliability for internet slot machines is also vital, and we have made sure that any online casino we recommend is properly licensed and regulated, has the eCogra seal of approval, and uses SSL encryption to keep your details safe. We would never recommend a site if we had any doubt in its authenticity.

We also look at the casino software to make sure it is easy to use and intuitive, as well as the welcome bonuses and loyalty schemes on offer to players. Finally, we assess the payment options available for deposits and withdrawals, as well as the speed in which payments reach your account.

So, while finding the sites with the highest payout casino games is important, it's not the only thing we consider when reviewing online slots casinos.

Game Developers and Their Best Paying Slot Machines

Online slots game development is a competitive part of the online gambling industry. The top games developers are constantly working to produce the highest paying slot machines and this is good news for players looking to land a massive win. For instance, top games developer NetEnt saw its jackpot slots pay out 78.3 million Euros in 2017, while Microgaming's Mega Moolah produced several multi-million dollar winners over the last year. Here is a brief guide to the jackpot games produced by some of the industry's major players:


Amaya, now known as the Stars Group, was established in 2001 and has grown steadily. In 2014, it purchased the parent company of Poker Stars and Full Tilt Poker in 2014 to become the world’s biggest publicly listed gaming company. Amaya is relatively new to jackpot slots but its Millionaires Island, a progressive slot that guarantees a minimum $1 million jackpot, launched in January 2017 and has proven to be a big hit with online slots players.


One of the world’s largest producers of slot machine games, Australian company Aristocrat Leisure dates back to 1953 and now incorporates a number of different casino gaming divisions. Its best known slots title is the famous Queen of the Nile, but it was also one of the pioneers of progressive jackpots thanks to its Hyperlink technology and its main progressive jackpot games Cash Express and Jackpot Carnival have produced regular big jackpots.


The company now known as Bally Technologies has been around since 1932 but didn’t enter the online gaming industry until 2013 and has produced popular titles such as Wild Huskies, Cash Spin and Vegas Hits. Among their roster are two games known for their high payouts.. Thunderhorn boasts an impressive 1024 pay lines, and Hot Shot, a classic fruit machine style game that offers a potential payout of 10,000 times your stake.


Founded in 1981, International Gaming Technology (IGT) is one of the world’s biggest creators of online slots titles. It has produced dozens of popular titles including Da Vinci Diamonds, Magic Castle and Siberian Storm and its progressive jackpot series of Mega Jackpot games has an average jackpot payout of $2 million.

Slot Machine


Established in 1994, Microgaming were pioneers of the online casino gaming industry, producing some of the world’s first online slots. As well as creating over 600 online casino games including high paying titles Cash Splash, Retro Wheels Extreme Heat and Scrooge, they have over 15 progressive jackpot games, of which the most well known is the Mega Moolah series, which has paid out numerous life-changing sums, including a £13.2 million payout to a Betway Casino player in the UK in 2015.



Established in 1996, NetEnt is one of the world’s leading online slots developers, creating such well-loved titles as Starburst, Blood Suckers and South Park. They also have a range of progressive jackpot games, including Hall of Gods Mega and the famous Mega Fortune, which holds the record for the biggest jackpot in online slots gaming: a massive prize of 17.8 million Euros, paid to a player from Finland in 2013.


European games company Novamatic was originally founded in 1980 and moved into online slots gaming in 2010. They have since produced a number of online favourites such as Book of Ra, Sizzling Hot and Dolphin’s Pearl. It also offers a handful of progressive jackpots including Elven Princess, King’s Treasure, Jolly Reels and Golden Sevens, which have produced a string of six-figure payouts.

Play N Go

Play N Go is one of the online gaming industry’s newest developers and has a reputation for producing cutting edge, mobile-friendly games. Their collection includes games such as Eye of the Kraken, Cloud Quest and Hugo. They haven’t placed as much emphasis on progressive jackpot games, but they have produced a few that can generate five and six-figure payouts, including Gunslinger and Fruit Bonanza.


Founded in 1999, Playteh has grown into one of the world’s foremost online slots developers. They are particularly well known for their high profile licensing deals with entertainment companies that have enabled them to produce movie-themed slots such as Justice League, Kong and Man Of Steel. They also have a large collection of progressive jackpot games, of which Beach Life is the most famous.

Real Time Gaming

Real Time Gaming was set up in Georgia, in the US, in 1998 and has become a leading player in the online slots industry. They are responsible for some of the world’s most popular games including Aladdin’s Wishes, Aztec’s Treasure and Cleopatra’s Gold, and though they are not best known for their progressive jackpot titles, they do produce a few, of which the best known is Aztec Millions.

The Biggest Wins on Record

Every casino goer wants to know which machines pay out the most, and it's the same for online slots players. There have been a number of headline grabbing real money wins that have caught the imagination of slots players in recent years.

The top payout for online slots came in January 2013 when an anonymous player from Finland won 17.86 million Euros playing the NetEnt game Mega Fortune. The same game also produced the third highest progressive win, by an anonymous Norwegian player, who scooped 11.74 million Euros in September 2011.

Mega Fortune may hold the record for the biggest slots online win, but it is Microgaming's Mega Moolah Mega that dominates the top five. A UK player named Jon Heywood scooped the second biggest payout for online slots when he landed a £13.2 million prize in October 2015 and Mega Moolah Mega also paid out the fourth and fifth highest online jackpots of all time in 2016, with two prizes of $11.6 million won by US players.

What The Best Payout Games Offer

There are a number of factors to bear in mind when looking for the best payout online slots. The first, and most obvious, is the size of the jackpot. For progressive jackpot slots online, this can be an eight figure sum, but while the record payouts may be eye catching, it is a good idea to check out the size of the average payout and establish how often the jackpot is won.

The best progressive jackpot games tend to be those with the highest profiles, as the more people who play a game, the faster the jackpot builds. That's why the best payout games are those that offer regular five or six figure prizes along with the occasional multi-million win. A game may offer a huge prize, but if research shows that it only pays out once every few years, you may wish to look elsewhere.

It's also important to look at other aspects such as the number of pay lines and maximum stake. The best payout online slots tend to be those with the highest maximum stake and in many cases you need to be betting the maximum to scoop the jackpot. The number of pay lines is also important. Some high paying games offer a high number of pay lines, in some cases, over 1000, which can lead to some big wins for players prepared to cover all the lines.

What is RTP?

RTP is short for Return to Player Percentage. When applied to online slots, RTP is a figure that enables players to see the house edge on a particular game at a glance. For example, if the RTP is 95 percent, that means for every $100 you wager on that game, you can expect a return of $95 on average. Details of a game's RTP can be found on a game's pay table.

It is also worth noting that the highest paying games tend to offer the lowest RTP. For example, the RTP of one of the world's most famous progressives, Mega Moolah, is 88 percent. When choosing which game to play, balancing the prospect of a big win against the online slot's RTP is an important consideration.
