Amazon first launched its Luna cloud gaming service in October 2020 with an invite-only program. The service then became available to all Fire TV owners without needing an invite a few months later. There are have been other ways to use the service without an invite since, but now Amazon is dropping all invite requirements for Amazon Luna in the US. If you haven’t tried the service yet, there has never been a better time since Prime members can now play a selection of games completely for free without needing to sign up for a free trial. If you don’t have a game controller, you can also now use a virtual controller through your phone before shelling out for a physical controller, like the Luna controller, which is currently on sale for $49.99. Amazon Luna games can be played through Fire TVs, Fire tablets, Windows PCs, Chromebooks, Macs, iPhones, iPads, and Android phones.
