Amazon is going all out to drum up excitement for Prime Day, its annual sales event that sees tons of products across all categories get temporary price drops. Prime Day 2018 is a 36-hour event that kicks off July 16 at 12 PM PT (3 PM ET / 12 PM BT) and runs through July 17. While we don't know exactly what items Amazon will put on sale during Prime Day, the company has already begun offering up free PC games for anyone who links their Amazon Prime and Twitch accounts. All told, 21 free games are available throughout July. The only catch? You have to be an Amazon Prime member to take advantage of the deals. Thankfully, there are some loopholes.

The free games for Prime members in July include Tacoma, Brutal Legend, Hue, and a whole lot more rolling out each day between now and Prime Day. You can find the full list here. And if you stick with your Prime membership after July, you'll continue to get a bundle of free games each month through Twitch--much like PlayStation Plus and Xbox Live Gold.
