Online Casino Software

Gaming software companies come in many forms, from the established slot machine designers from previous generations to the Internet startups which got famous during the online gambling boom of the 1990s and 2000s. This page gives a quick review of the major online casino software providers, along with discussions of any land-based casino game machine hardware manufacturers which need to be covered. These tend to be two entirely different worlds, though they bleed over into each other occasionally--and borrow game design ideas from each other a lot.

Examples of those websites include Rome Casino, Black Diamond, 7Spins, Box24 Casino, 21 Dukes, Thebes, Winward, and Mona Online Casino.

Rival Gaming is another software development firm which accepts US players, making it the top rival to RTG in the American market, with 46 English language online casino sites and 2 non-English websites it powers. Superior Casino and CRC Casino are two of its most popular clients. For a somewhat lesser known software provider, I've always thought Rival Gaming's slot machine selection was excellent. The themes are interesting and the graphics are as good as you'll find in the industry.

If you don't play a lot of bingo and skill games, you might not be as familiar with NetEnt as some of the other selections on this list. You should be, because NetEnt powers 124 English language gambling sites and 23 more international language properties, making it Top 5 in terms of clients. Often, Net-Ent gets overlooked when listing off these big companies, because Netent often appears on sites alongside other gaming platforms. For that reason, you'll see brand names like Sky Vegas and Unibet being powered by Netent--and others. You'd be amazed at the graphics on some of the NetEnt 3D Slots. If you want to look up examples, I suggest Robin Hood, Boom Brothers, and Gonzos Quest. The next couple of companies are even more heavily invested in this niche.
