In addition to being one of the best slot providers, Merkur Gaming is an international company with operations all over the world while Merkur Games are accessible at around half of all online casinos in the United Kingdom (although they do not yet rank among the top 100 UK market suppliers).

Merkur Gaming is a game development firm that is owned by the Gauselmann Group, a German firm. The company has developed over 200 slots, each with its own style and unique characteristics.

That said, they still provide a wide choice of traditional fruits and more advanced video slots to also suit the tastes of the traditional slot gamer.

#10. Rival

Rival - best slots providers

Rival, which was founded in 2006, is neither a veteran nor a newcomer in the slots business.

Nonetheless, they’ve built a collection of engaging and graphically rich titles with interesting animations accessible in both downloadable and live play versions over the course of their decade in business.

Highly interactive iSlots are a unique treat, with each one telling a tale whose progression is determined by your abilities and luck during the slot game’s bonus rounds. Some of our favorite examples include As the Reels Turn, Cosmic Quest, and Reel Crime.

The best Rival slots can be found in more than a few popular online casinos and are also accessible to US players.

With their beautifully designed and perfectly executed slot games, Yggdrasil didn’t take long to get established as one of the best slot providers within the international gaming community. Their high-adrenaline action slot games are not just a pleasure to look at, but also to play!

This rising star regularly offers comprehensive packages that consist of high-quality and modern design, engaging themes, and well-developed concepts, as well as a number of distinctive additional features.

It’s not simple to pick the best Yggdrasil slot out there, but we’d go with Double Dragons, Legend of the White Snake Lady, Big Blox, and Bicicleta. Anyway, this slot provider has countless games available on a wide range of devices to make you a lifetime fan!

#8. Williams Interactive (WMS)

William Interactive (WMS)  - best slots providersPlay WMS slots at Leo Vegas Casino

Specifically, in 1996 WMS launched Reel ‘Em In, the first American video slot machine offering a second-screen bonus round, and in 2012 Williams Interactive was formed to exploit the company’s experience in the online arena.

Players from all around the world may now enjoy slots with locking symbols, cascading reels, additional rows, and a range of other features designed to increase players’ chances of winning. Not to mention, WMS’ portfolio includes a number of games with very high RTPs that range from 98 to 99 percent.

#7. IGT

IGT - best slots providersPlay IGT slots at Videoslots Casino

IGT, also known as International Game Technology, is a significant producer of casino software for both online and land-based casinos. IGT’s portfolio isn’t extensive, since the company appears to value quality over quantity, but it does have entertaining slots with a variety of themes and reasonable payout possibilities.

Some of the best IGT slots include Da Vinci Diamonds, Wheel of Fortune, Wolf Run, Family Guy, and Pharaoh’s Fortune.

#6. Play n’ Go

Play N' Go - best slots providersPlay Play’n Go slots at Casino Cruise Casino

Sweden is such a fertile ground for breeding some of the best slots providers and software developers and Play’n Go is one of the examples.

Their slots are quite popular because they meet all of our criteria. They are visually appealing, have original themes and execution, are action-packed, and have a number of features with a high win potential. It’s difficult to pick a favorite among the best Play’n Go slots, but Riches of Ra, Aztec Idols, Cops n Robbers, 7 Sins, Aztec Princess, Book of Dead, and Wild North are all popular among players.

#5. Realtime Gaming

Real Time Gaming - best slots providers

Since 1998, RTG has been one of the best slot providers, offering games to both US and international gamers.

Daily, weekly, and monthly slot tournaments, which allow players to compete against their peers for cash rewards, are a popular RTG feature. The best RTG slots come in both downloadable and immediate play formats.

Something we should definitely mention, however, is that the company’s popularity among operators, but not as much among players, comes from the fact that it allows casinos to pick how high or low a game’s payout percentages will be.

#4. Playtech

Playtech - best slots providersPlay Playtech slots at BGO Casino

Playtech was established in 1999 and has since become one of the best slots providers globally. The company has pushed its competent nose into pretty much everything, resulting in a portfolio that includes traditional and video slots, table games, video poker, bingo, scratch cards, poker, live games, and fixed odds games.

When it comes to the top Playtech slots, the developer is best known for the universally liked Marvel Series slots, including Iron Man, Fantastic Four, X-Men, and The Incredible Hulk, as well as movie and TV series themed titles like Rocky, The Mummy, and The Sopranos. Some of our favorites, however, and progressives such as Beach Life, Jackpot Giant, and Gold Rally as they have the potential to create multi-millionaires.

#3. NextGen / Nyx Gaming Group

Thanks to fantastic graphics and animations, as well as a variety of creative in-game features, NextGen slots are instantly recognizable. The SuperBet feature, for example, allows you to place an extra stake that increases your chances of winning, and it’s frequently used in conjunction with enhanced wilds and free spins.

#1. Microgaming

Microgaming - best slots providersPlay Microgaming slots at Casino Cruise Casino

Our best slot provider in the list doesn’t really need an introduction.

The company is always developing and surprising us with innovative concepts and flawless implementations. Their slots are available in both download and instant-play versions, but because of US gambling legislation, they have been unavailable to American players since 2008.
