What It Is

CLI-Games is a library of games that you play programmatically. The games reinforce one another - what you learn in one game leads to experiences in another.

There are classic games reimagined for the terminal, challenges that require Linux mastery, and RPG universes made entirely out of ASCII.

The competencies you build here transfer to real systems. We teach you to play - you learn to wield.
