To claim some offers, you will link your Amazon Luna account to your game account. For example, in order to claim content for Riot Games titles such as VALORANT or League of Legends, you will be prompted to sign into your Riot account. This tells the game you’re an Amazon Luna member, so it can unlock the respective content for you, at no additional cost.
Make sure you have your game account details handy—or, if you don’t have a game account, you will need to create an account.
Many of games you can access with Prime are offered via GOG, the Epic Games Store, Legacy Games, or through the Amazon Games app.
Once you’ve linked your Amazon Luna account to these game publisher and game-launcher accounts, Amazon Luna will remember. This makes claiming these games and in-game content offers is often as easy as a single click.
Moreover, many of the in-game content offers span multiple platforms and can be enjoyed across PC, Xbox, PlayStation, and more, where applicable. In some cases, the in-game content appears automatically in your game after you’ve successfully claimed said content and linked the relevant account.
