If you're an Amazon/Twitch Prime subscriber, you probably know you get a handful of PC games for free each month. But July isn't just an ordinary month for Amazon. Prime Day is kicking off on July 16, bringing deals of all kinds for Amazon Prime members. But the celebration isn't limited to Prime Day itself. In addition to three games that will be free all month for Twitch Prime members, the company is giving away one free PC game every day during the lead-up to the shopping holiday. All told, 21 free games are going out this month for free to Prime members.

To claim your free games each day, you can either click here or visit Twitch.tv and click the crown-shaped button next to the search bar at the top.
