How to Access Prime Gaming (Formerly Twitch Prime)
All Amazon Prime members get Twitch perks for free
Prime Gaming is automatically included with your Amazon Prime or Prime Video subscription. Obviously, you need to sign up if you haven't already. Then, you need to link your Twitch account with your Amazon Prime account to access Prime Gaming's features. Here's how to do it.
Go to Prime Gaming.
If you don't already have Amazon Prime, select Try Prime and follow the prompts to complete the membership sign-up process.
If you already have Amazon Prime, follow the prompts to connect your Twitch account to your Amazon account.
Select Confirm when prompted to finish the account linking process.
You should now see a popup window with a variety of subscription options. Choose Subscribe Free under the Free Subscription with Prime section.
Unlike paid Twitch subscriptions, the free one doesn't automatically renew each month. Free subscriptions must be renewed manually using the same method described above.Source Article : Lifewire.com by Brad Stephenson
