15 Free Open Source Games For Linux

Although Microsoft and macOS are the most common operating systems when it comes to gaming, Linux is slowly becoming a favorite for gamers. 

The introduction of open-source games has also significantly changed the gaming world by giving players and other developers the ability to study, download, and modify the code as they see fit.

What is an Open Source Game?

An open-source game is a video game that allows users, programmers, and developers to download the game’s source code and make changes to it. Most open-source games are free because most developers do it for fun and not necessarily to make money from it.
