Right now, there are a lot of free games available, ranging from Epic’s weekly freebies to publisher promos on Steam, GOG sale giveaways, and more. However, keeping track of them all can be a real pain, and you might be missing out on some great opportunities.

Free-to-keep and temporary promotions will be included and noted as such, but free-to-play games and others that are normally free will not be—for that, check out our categorized breakdown of the best free PC games.

Prime Gaming:

You have to be a subscriber to play the games on Prime Gaming, so they aren’t technically free. However, there’s a lot on offer if you are, including in-game loot and free-to-play game starter packs, so it’s worth keeping an eye on. Prime Gaming is included with Amazon Prime for $13 per month or $120 per year; amazon.com has links to all of the included freebies.
