“You’re the OS” is a web-based game aimed at computer enthusiasts who want to try to keep apps alive on a computer before the user forcefully terminates them.
To play the game, it’s helpful to have some basic knowledge of how processors and RAM memory work. The player’s task is to allocate the processes running in the operating system to the computer’s four processors and distribute the RAM memory so that the processes can run.
If a process takes too long to execute, the “user” becomes angry and forcibly terminates the process. When the user has forcibly terminated ten processes, they reboot the computer, and the game is over.
