Worlds biggest online slots producers

There are loads of companies throughout the world concerned with creating fantastic online slot machines. While nearly all of them have some good games, there are three companies above all others that dominate the market: Microgaming, Playtech and NetEnt. You’ll find slots from at least one of these giants at the majority of online casinos in the UK, and they’re always innovating and coming up with new games month after month.

On this page, we’ll take a look at these three companies, and will tell you about the slots they offer, as well as run you through some of the slots they’ve produced that we think are the best.


Microgaming is the biggest slots company in the world, and dwarfs even the other two names on this page. They were formed way back in 1994 and had a hand in creating the world’s very first online casino, so they certainly have the experience to give slots enthusiasts exactly what they’ll want. Some casinos offering Microgaming games include Casumo, 32Red and Conquer Casino, and some of the best Microgaming titles are:

  • Mega Moolah
  • Game of Thrones
  • Major Millions
  • Thunderstruck II
  • The Dark Knight Rises


Playtech is another huge name in the online casino business, and many UK slot sites use their software. They’ve also been around for a very long time – although not as long as Microgaming – and have amassed a great portfolio of games, which range from progressive jackpot slots, all the way through to video poker and table games. Some of the names using Playtech software include Paddy Power, Bet365 and Gala Casino, and some of the most popular games are:

  • Gladiator
  • Age of the Gods
  • Monty Python’s Spamalot
  • Beach Life
  • Frankie Dettori’s Magic Seven


The last name on the list is NetEnt, and they are known for one thing above everything else: innovative and exciting games. They haven’t got as many titles as Microgaming and Playtech, but they’re always pushing the boat out somehow, and new NetEnt slots will contain something special, like innovative bonus features, top-class graphics, or massive prizes. NetEnt slots are found at, among others,, Conquer Casino and Royal Panda, and top games include:

  • Mega Fortune
  • Gonzo’s Quest
  • Guns N’ Roses
  • Planet of the Apes
  • Starburst
