Every month, live-streaming platform Twitch hands out free games -- and April's batch just dropped.
You also need to have a Twitch account (it's free to sign up), and then you'll have to link it to your Prime account.
From there, just head to the Amazon Twitch page and scroll down to the Games with Prime section at the bottom.
To actually play them, you'll need either the Amazon Games App or Twitch Desktop.
