A developer that's been around for some time, Games OS were called CTXM in the past and they've built a reputation for themselves that is based on the quality of the slots they create and on the software platform they provide. They have their own casinos that rely solely on their software, but they are also included on some casinos that pool together games from multiple providers. More than 150 games are offered as part of the Games OS collection that mostly covers the Slots, but will also have titles for everyone else (real time titles, table, video poker, scratch cards, arcades, etc).

English, Spanish, Romanian, Greek, Chinese, Russian and German are among the languages that the software is translated in.

The software they offer is available for the players via the browser, being based on the Java and Flash technologies. The support staff is online 24/7 and they help the players through the live chat if they happen to need any help with the game.
