The company designs, manufactures, sells, and services gaming and coin-operated amusement equipment including slot-machines, video games, instant ticket lottery games, and German wall-machines, which are wall-mounted slot-machines. The fun and games began in 1931, during the Great Depression in Chicago, current site of Bally headquarters.

I’m planning to include some reviews of various gambling machines here soon, so I thought I’d start with a look at some of the slot machine manufacturers and their products. There was a time, not long ago, when such a list would be short. But with the advent of internet casinos, the list of slot machine companies grows longer every day.

Of course, depending on where you live, you might be searching for such information using a phrase like “fruit machine suppliers” or “gaming companies.” Such a list should (and does) include old slot machine brands like IGT (International Game Technologies) and internet casino software vendors like Microgaming and Playtech.

As I create more posts about related subjects, I’ll update this page with links to manufacturer-specific lists of games and reviews of their overall offerings.

I know that a lot of sites in this space try to offer as complete a resource as possible, but please remember that I’m just one guy with a blog. I don’t have an army of freelance writers working for me, and even if I did, there are so many slot machine games from so many different providers that it would be almost impossible to keep up with them all.

But if I’ve left out your favorite slot machine manufacturer, let me know in the comments, and I’ll add it to the list.

Slot Machine Manufacturers List – Updated 2020

And here’s the list of slot machine manufacturers:

1. Ainsworth Game Technology

Ainsworth Game Technology is one of the oldest companies on my list of slot machine manufacturers. They’ve been in business for 20+ years. Ainsworth is an Australian company, and if you know anything about gambling in Australia, you know how popular slots are there. They call them “pokies,” though, which is an abbreviation for “poker machines.”

And some of Ainsworth’s most recent game additions include:

• Action Dragons
• Big Hit Bonanza
• Pac-Man Wild Edition

2. Amatic Industries

Amatic Industries has been in business for over a quarter of a century now. Besides slot machines, they make video lottery terminals and video roulette games. They have a huge selection of slot machine brands in their stable, too, including some of the following:

• Games Bond (Yes, this is a “James Bond” knockoff.)
• GrandX (A “Wheel of Fortune” lookalike.)
• Vampires (A simple enough theme and title, no?)

3. Amaya Gaming

Amaya Gaming is defunct now. It’s part of The Stars Group, the company which owns PokerStars. I include it here under its original name because I think some online users still look for games from Amaya Gaming. They offer lots of cute games, including:

• Barn Yard Boogie
• Jenga
• Street Fighter II

4. Aristocrat Gaming Technology

Aristocrat Gaming Technology is another Australian “poker machine” vendor. They’e recently gotten their hands on some major intellectual property, too, and they offer games like:

• Batman Classic TV Series
• The Big Bang Theory
• Britney
• Game of Thrones
• Sons of Anarchy
• The Walking Dead

5. Ash Gaming

Ash Gaming used to be a big deal, now they’re a part of Playtech. As part of that group, they have extensive licensed properties to create games about. Their most famous, though, is probably Who Wants to Be a Millionaire.

6. Bally Technologies

Bally Technologies is now a subsidiary of SG Gaming (Scientific Games). The company has been around forever. Not only do they make slot machines, but they used to be one of the biggest pinball machine companies in the world, too. Some of their most well-known brands include:

• James Bond
• Monopoly
• Willy Wonka

7. Barcrest Gaming

Barcrest Gaming–like Bally Technologies– is also now a subsidiary of SG Gaming (Scientific Games). If you’re a real slot machine aficionado, you might recognize the names of some of their games:

• Deja Vu Diamonds
• Flippin’ Out
• Psycho Cash Beast

8. Betsoft Gaming

Betsoft Gaming specializes in online gambling games, especially mobile friendly slots and 3D games. Here are some of their titles:

• Dragon Kings
• The Golden Owl of Athena
• Ogre Empire (which has a suspicious resemblance to the movie Shrek)

9. Blueprint Gaming

Blueprint Gaming is based in the United Kingdom. Most of their fruit machines can be found on casino floors there or in Germany and Italy. Here’s a sample of their titles:

• Fairy Fortunes
• Slots o’ Gold

10. Cadillac Jack

Cadillac Jack was a subsidiary of Amaya Gaming, which is now wholly owned by The Stars Group.

12. Endemol Shine Gaming

Slot Machine Manufacturing Companies In Navi Mumbai

Endemol Shine Gaming specializes in both online and brick and mortar gambling games. Some of their best-known properties belong to the licensed television game show genre. Some examples include:

• Deal or No Deal
• MasterChef
• Million Pound Drop

13. Fremantle Media

Fremantle Media is one of the more unusual listings on this page, because they don’t exactly design or manufacture slot machine games. They own several large television brands, which they aggressively promote through multiple channels–including slot machines. If you’re playing one of these slots, Fremantle Media had a lot to do with it:

• American Idol
• Blockbusters
• The X Factor

14. The Gamesys Group

The Gamesys Group does slots and bingo games. Some of the better known brands in their stable include:

• The Godfather

• Cats
• Golden Goddess
• Photographing Fairies

17. IGT (International Game Technology)

IGT is far and away the largest slot machine company in the world. They’re everywhere. The most popular gambling machines in the casino are the product of International Game Technology. Just a few of their big names include:

• Family Guy
• Jeopardy
• Siberian Storm
• Wheel of Fortune

18. Konami Gaming

Konami Gaming is the maker of the following slot machines:

• Battlestar Galactica

I’ve written about Microgaming before, here.

22. NewGin Co. Ltd.

NewGin Co. Ltd. is another Japanese manufacturer of pachinko and pachislo machines.

23. NextGen Gaming

Slot Machine Manufacturers Association

NextGen Gaming serves both online and land-based casinos. They offer some really cool titles, including:

• King Kong Fury
• Samurai Split
• Wonder Hounds

24. Novomatic Gaming

The name “Novomatic” always reminds me of the Steve Goodman song, Vegematic.

But that song has nothing to do with the company, though. Novomatic Gaming is probably the biggest European slot machine maker there is, in fact.

Some of their games you’ve probably heard of include:

• From Dusk Til Dawn
• Stories of Infinity
• Treasure of Tut

25. Ortiz Gaming

Ortiz Gaming specializes in Class II and Class III slot machines, especially when it comes to bingo technology. And their games are OVERTLY bingo-based, too:

• Allstar Bingo
• Rodeo Bingo
• Multimania

26. Playtech

Playtech is another online game designer and creator, and, like Microgaming, they’re publicly traded. They also don’t allow their licensees to accept real money players from the United States. Some of their better known games include:

• Ace Ventura
• American Dad
• Batman Begins
• Grease
• Justice League
• Pink Panther
• Rocky

27. Realtime Gaming

Realtime Gaming (RTG) is probably the biggest online casino game vendor that still serves U.S. audiences — at least the audiences that don’t live in states with legal, regulated online casinos. (There are 47 states like that.) As a result, you’ve probably never heard of most of their games unless you’re a devoted internet gambler.

My favorite of their games is It’s Good to Be Bad, but I’m old school.

28. SG Gaming (Scientific Games)

Scientific Games is headquartered in Las Vegas. They own Bally now, and they own Shuffle Master. And they also own WMS Gaming. Their most well-known game is probably Monopoly slot machines.

29. Universal Entertainment Corporation

Universal Entertainment Corporation is another pachinko and pachislo manufacturer.

30. VGT (Video Gaming Technologies) – One of My Favorite Slot Machine Manufacturers

VGT is one of the biggest names in the Oklahoma gambling market, and they specialize in bingo-based slot machine games.

31. WMS Gaming

WMS Gaming is now a subsidiary of Scientific Games. So see that entry above.

The Final Word about Slot Machine Manufacturers

The brand names in the slot machine manufacturers category are many, but, of course, IGT (International Game Technology) towers above the rest like Walmart towers over other retail establishments. The list above gets longer when you account for the companies making online slot machine games, too.

If you have any comments about the games available from these corporations, I’d enjoy hearing them. I’m human and make mistakes, so if you leave a comment pointing one out, I’ll update this post with corrections (and probably even give you credit.)

General Reference (not clearly pro or con)

John R. Patrick, Doctor of Health Administration (DHA), President of Attitude LLC and former Vice President of Internet Technology at IBM, in his 2016 book titled Election Attitude: How Internet Voting Leads to a Stronger Democracy, wrote:

“At one point, there were 19 voting machine companies listed in the Federal Election Commission Buyers Guide, but the guide is no longer available. Through a series of mergers, acquisitions, and business failures, the voting machine industry currently is dominated by the three companies. All three companies are privately held and do not disclose their revenue or profits.

Dominion Voting Systems Corporation is based in Toronto, Canada. It sells electronic voting and tabulating hardware around the world. In May 2010, Dominion acquired Premier Election Solutions, formerly Diebold Election Systems, from Election Systems & Software. They just had acquired Premier Election from Diebold, but were required by the United States Department of Justice to sell Premier Election Solutions for anti-trust concerns.

Election Systems & Software, based in Omaha, Nebraska, is the giant of the voting machine industry. In addition to a line of hardware products, the company provides equipment rental, print services, maintenance services, ballot management services, election support, professional services, and voter registration mailing services. The company’s equipment, software, and services are used by municipalities and counties throughout the U.S.

HartInterCivic based in Austin, Texas, has been working with election professionals for more than 100 years. The company makes a wide range of voting machines hardware and services. Its election services include consultation, training, professional services, preventative maintenance, and ballot production services. The company claims its mission is to help advance democracy one election at a time.”

2016 -John R. Patrick, DHA, LLB

The Voting Industry website included a list of electronic voting machine vendors, categorized into tiers based on their market prominence (accessed Aug. 17, 2006):

“First Tier voting systems vendors – We again consider First Tier vendors to be firms you simply can’t ignore. The grouping here is somewhat artificial. However, these are the big 4 vendors that control the lion’s share of the industry: Election Systems and Software [ES&S], Diebold Election Systems, Sequoia, and Hart Intercivic.

Second Tier voting systems vendors include: AccuPoll (has filed for bankruptcy), Advanced Voting Solutions, Avante, Unilect, and Voting Technologies International.

Internet and other voting system vendors – Here is a list of of Internet Voting Companies, Regional Voting Firms and Other elections firms that may have older or very new products: AutoMARK Corporation, Comfidex Corporation, Danaher Corporation, Democracy Systems, MicroVote, Populex, SafeVote [Internet voting systems only], Dategrity (formerly VoteHere), and TruVote.”

CorpWatch, a corporate watchdog website, published a Sep. 8, 2004 article titled “November Surprise: Electronic Voting Machines Add Uncertainty to Close Election Races,” which stated:

“The Federal Election Commission states that 19 companies produce DREs [as of Feb 20, 2003; list has since been removed from the FEC website; last attempt to access on Aug. 17, 2006], but the market is dominated by just four: Election Systems and Software (ES&S), Diebold Election Systems, Sequoia Voting Systems, and Hart Intercivic.

Between DREs and other voting technologies, machines of these four companies will tally nearly 100 million votes this Election Day, the vast majority of those cast. Furthermore, nearly 50 percent of precincts will use machines created by ES&S.”

The Verified Voting Foundation included a list, organized in alphabetical order, of electronic voting machine vendors on its website (accessed Aug. 17, 2006):

“Advanced Voting Solutions; Avante International Technology; Danaher Controls; Diebold Election Systems; Election Systems and Software, Inc. (ES&S); EVS (The Association of Electronic Voting Systems); Fidlar Doubleday; Hart InterCivic; MicroVote General Corporation; N.V. Nederlandsche Apparatenfabriek ‘Nedap’; Sequoia Voting Systems, Inc.; TruVote International, Inc.; Unilect Corporation; VoteHere, Inc.; and Voting Technologies International.”

The Election Technology Council stated in the “Frequently Asked Questions” section of their website (accessed Oct. 2005):

“The Election Technology Council (ETC) is a group of companies that offer products and services which support the electoral process and decided to work together to address common issues facing the industry. These companies believe that the voting infrastructure in the United State in pressing need of improvement, and that electronic systems introduce new levels of voting inclusiveness, accuracy, efficiency and accessibility…

Founding members of the ETC are: Advanced Voting Systems, Diebold Election Systems, Election Systems and Software, Hart InterCivic, Sequoia Voting Systems, and Unilect Corporation. The Council has been joined by Danaher Guardian Voting Systems, VoteHere, and Perfect Voting Systems.”
