Review of GamesOS casino software

GamesOS is a Latvia-based online betting software developer that provides their games to casinos that are generally partnered up with multiple developers. Originally known as CTXM before rebranding in 2012, the company has grown to include several social betting games, which are featured on sites like Facebook.

GamesOS custom designs their own games, and also designs gaming platforms which are then offered on desktop and mobile devices. The company's video slots, arcade games, video poker, and table games are available directly through the web, requiring no software installation no matter the system you use.

Video slots are the biggest selection of games offered by GamesOS, and range from holiday themed slots, to outer space, music, party, and horror themed games. The company generally does an ordinary job with their games, developing slots that look decent but aren't anywhere near as well designed as the titles from their modern competitors. Worse still is that to me, most of their slots aren't really all that much fun to play.

GamesOS also has table games, but the selection isn't very large. The majority of these games are roulette, which have a few variations. You will also find craps and Sic-Bo on offer. Those who like video poker and arcade games will also find them, along with a bunch of scratch cards.

There are only a small number of online casinos that offer titles from GamesOS, likely due to the relatively low production values. The pick of the bunch at this point in time are probably Video Slots Casino and SlotsMillion. Do be careful where you play these games though, as some of the lesser casinos we have found them at have predatory terms, bad bonuses, and win-caps.


GamesOS software is okay, but the games aren't particularly polished. There is a wide range in the quality of the casinos offering their games, so you should choose carefully. The software does have a nice library and is available on mobile platforms, but there really isn't any reason for you to go out of your way to play these games.
