Top Online Slots Software Developers
One of the main reasons online casinos are able to host hundreds or even thousands of slot games is because of the range of top software developers working to produce them. Each provider has its own strengths and special areas of interest, which is what makes the online slots market so varied and exciting. Let’s take a look at a handful of the industry’s top online slots developers below.
Swedish developer NetEnt is truly one of the giants of the casino industry. Since its founding in 1996, it’s placed itself at the heights of the slots market, in part thanks to the successes of 2011’s Gonzo’s Quest and 2012’s Starburst. The company has gone bigger and better in the decade since, however — producing a number of popular titles such as Silverback Gold, Dead or Alive, Shangri La and Blood Suckers.
NetEnt is also known for its music-themed games, such as the Guns N’ Roses and Jimi Hendrix slots, and isn’t afraid to revamp the classics, with Gonzo’s Quest Megaways and Starburst XXXtreme cooking up a storm in recent years. The developer’s crowning at the 2016 EGR Awards as winner of Innovation in Slot Provision, along with the company’s acquisition by live dealer experts Evolution Gaming in 2020, further affirms its status as iGaming royalty.
Other popular slots in the NetEnt portfolio include:
- Dead or Alive 2
- Twin $pin
- Fruit Shop
- Divine Fortune

The Isle of Man-based developer has also picked up multiple awards over the years, including iGaming Software Supplier of the Year at the 2018 International Gaming Awards and EGR’s Innovation in Slot Provision award back in 2011. In 2022, Microgaming sold its entire back catalogue of games to Games Global Limited, though this shouldn’t impact the availability of Microgaming slots at online casinos and slots sites.
