How does the Amazon Prime Gaming rewards system work?
I was wondering, whenever I log into Twitch, I see the notifications of past Amazon Prime Gaming rewards and most of them have a claim button.
Since I have never bought the subscription, I wanted to know if I bought the subscription will I be able to claim these past rewards (or expired rewards?) or the claim button is a bug or an error that never got fixed?
Every reward has a window you can claim it in. When the window passes you cannot get the reward anymore. If it has a claim button that window has not passed, and you can claim it while you have an active subscription. Once you claimed the items, you do not need the subscription to keep the items.
You can see the status of all your claimable rewards at: https://gaming.amazon.com
Old rewards whose windows have passed are removed from the list and are not visible.
