You can access Xbox Game Pass cloud games via any modern web browser via Xbox.com/play, or using the Xbox Game Pass app on Windows 10, Windows 11, Google Play or the Galaxy Store on Android. A lot of the games here also support touch controls, and the save files will sync to and from your Xbox console (and your PC as well if the game supports Xbox Play Anywhere, although you can just play the cloud version on your PC as well). All xCloud versions are in fact the Xbox console version, as the cloud servers are based on Xbox console architecture.
