Here are some of the best online resources dedicated to freeware and free PC games. Some are dedicated to freeware games only, offering downloads of homebrew games, clones, and older commercial games that were released as freeware. Other sites offer a mix of content, including online browser-based games and downloadable games.

This is a great place to start if you're looking for free PC games online!

Kongregate is a website that offers free online games. It has a large library of games in various genres, including action games, tower defense, MMOs, and more. Once you log in, you can play for hours, collect badges, and earn achievements.

While many view Steam as the primary online platform and storefront for purchasing PC games, it also offers hundreds of free-to-play games. Some are free during an early access period while they’re still in development. Others are fully released titles that offer in-game microtransactions. That said, a vast majority of free-to-play PC games offered on Steam do not require payment for access to full functionality and gameplay.
