Best Online Casino Software Providers

Aristocrat

This Australian company is one of the biggest slot game developers in the world. Responsible for superstar games like the Buffalo series, Aristocrat's titles have garnered legions of fans for their big jackpots and charming gameplay.

Currently, the software provider is licensed in more than 240 jurisdictions for online gambling. Aristocrat titles are so popular players will easily find them in the biggest online casinos, including Royal Panda and 888casino.

Bally

Bally's history in gambling stretches back to 1936 when it was the world's oldest slot machine manufacturer. Today Bally is renowned for its retro-style Vegas slot games, including Blazing 7s and Hot Shot. The company was bought by rival Scientific Games (SG) in 2014, so players should look for the SG or Bally logos when searching for their casino games online.

Barcrest

The brand may have started out in 1968 developing as a game supplier for bricks-and-mortar casinos, but that's all in the past. In the last three decades, the game company's transition to online casino games has given players huge titles, such as Rainbow Riches.

The casino software provider is known for creating inventive slot games that suit both low-limit and high-stakes bettors. Like Bally, Barcrest was absorbed under Scientific Games' brand, but players can still find its games at popular casinos like Betway.

Betsoft

Founded in 1999, Betsoft's collection of 150 games features countless themes that cater to a wide audience. The software provider specializes in cinematic 3D gaming for slots, blackjack, video poker, lottery, and table games. It has also created a special line of 'To-Go' games optimized for mobile users with iOS and Android operating systems.

More than 500 online casinos feature Betsoft's games on their sites, including LeoVegas and Mr Green.

Blueprint

Blueprint started out in the early 2000s as a land-based casino provider but soon after pivoted to online gambling. The software provider focuses exclusively on slot games, from classic three-reel fruit machines to complex progressive jackpot slots. Players may recognize some of Blueprint's famous titles: Eye of Horus, Rick and Morty, and Deal or No Deal Megaways.

The game company has a flair for adding innovative (and lucrative) features to its slot games, such as the Megaways™ function or progressive system found in its Jackpot King series. As a result, players will only find Blueprint titles at premium slot casinos. Alternatively, bettors can try some of Blueprint's games at our free slots arcade.

Big Time Gaming (BTG)

Big Time Gaming, better known as BTG, is an Australia-based company renowned for creating groundbreaking slot titles. The game provider is responsible for inventing the famous Megaways™ mechanic, which shifts reels to give players 117,649 ways to win slot games. After releasing the Megaways™ function in 2016, BTG enjoyed meteoric success with its Bonanza Megaways slot game. This encouraged the software provider to turn its Megaways™ feature into a franchise, which the likes of SG, Blueprint, and Red Tiger have incorporated into their games.

International Game Technology (IGT)

Since being founded in Las Vegas in 1975, IGT has established itself as a heavyweight in online gambling. The software provider has created more than 1,000 slot, video poker, and other online casino games for gambling sites worldwide. As IGT expanded into countries like Japan and the UK, it has acquired other game companies, including Barcrest and Wagerworks.

IGT's classic slot games, such as Cleopatra and Wheel of Fortune, have enduring popularity due to their history of dishing out unusually high jackpots. Players can find these and other popular IGT titles at all major online casinos.

Microgaming

Microgaming is one of the giants in online gambling, having more than two decades of experience creating games for casino sites. The software provider creates pioneering slot titles and poker games. Its progressive jackpot slot, Mega Moolah, has broken several world records and spawned dozens of copycat games.

In fact, Microgaming has endless hits to its name: Break Da Bank, Jurassic Park, and Game of Thrones are just a few to name. It's unsurprising then that players can find Microgaming's portfolio of games at most online casinos.

NetEnt

NetEnt is one of the most popular game companies in online gambling due to their branded titles through partnerships with Universal and South Park Digital Studios. The software provider launched in 1996 and has made more than 200 titles for slots, live dealer, and progressive jackpot games. Along with its own NetEnt online casinos, over 100 gambling sites feature games from this software provider in their collections.

Novomatic

With more than 40 years of experience creating land-based and online casino games, Novomatic is one of the most recognizable names in gambling. The game company specializes in slot titles, with award-winning games like Book of Ra in its portfolio.

Novomatic operates in over 40 countries, with a particularly loyal slots fanbase in Europe. On average, Novomatic generates €5 billion a year in revenue, making it one of the most successful software game providers. Players can enjoy Novomatic's slot games at popular gambling sites like Grosvenor Casino.

Playtech

Playtech originally started as a small game studio in 1999 and has since gone from strength to strength. Today the game company operates in over 20 countries and has acquired other software providers (QuickSpin and Ash Gaming). While Playtech's most popular titles are slots, it also creates blackjack, live dealer, poker, and roulette games. Playtech even has its own bingo sites.

Jackpot Giant and Gladiator are just a few Playtech slot games that bettors can find at most online casinos.

Play 'N' Go

Slot fans wanting games with a high return-to-player (RTP) should look no further than Play 'N' Go. The game company is the mastermind behind the hit Book of Dead game and regularly launches slot titles with high RTPs and jackpots. Play 'N' Go also makes other online casino games, albeit on a much smaller scale compared to its slots offering.

After starting out as a subcontractor in 1997, Playtech became an independent company in 2014 with offices throughout Europe and the Philippines. The game company's titles feature in many online casinos

Red Tiger Gaming (RTG)

Red Tiger Gaming is renowned for its action-packed slot games and fun features. With its Smart Spins mechanic, regular slot tournaments, and Daily Drop Jackpot promotions, it's easy to see why this software provider has expanded rapidly across European and Asian online casinos.

Despite only launching in 2014, RTG was quickly acquired by NetEnt. Since then, RTG continues to launch its own games as well as collaborative efforts with NetEnt.

Scientific Games (SG)

Scientific Games is a leading name in online gaming. The juggernaut has been in the gambling industry since 1968 and has acquired numerous software game providers since its inception. Over time SG has created bingo, roulette, and video poker games for casinos, but it is most famous for its slot titles. Bettors will recognize SG's distinctive retro-style games, such as Goldfish, at any online casino.

Williams Interactive (WMS)

Another subsidiary of Scientific Games, WMS first started out in 1974 as a pinball manufacturer. As WMS grew, it expanded into mobile gambling and created a host of innovative table games and slot titles. The game company was a pioneer in slot games, adding stacked, expanding, and chained wilds long before other software providers.

What really promoted WMS in the online gambling industry was its film-themed slot games. James Bond, Top Gun, and The Wizard of Oz are a small selection of WMS slots that players can still find in online casinos. Combine that with the high RTPs WMS slots have (96-99%), and it's easy to see why players love this game company.

Yggdrasil

When Yggdrasil arrived on the gambling scene in 2013, the game company was keen to disrupt the industry. With its innovative features and high-quality artwork, Yggdrasil quickly garnered top awards for its engaging portfolio. Slots are Yggdrasil's specialty, but bingo, blackjack, and table games are also a focus for the game provider.

Despite its small size and relative infancy, Yggdrasil's collection can be found at many of the best online casinos.
