Thief

You've broken into a machine. Passwords are hidden across the filesystem — each one grants you access to the next user. Find them all and take the machine.

The game teaches fundamental Linux skills: reading files, handling unusual filenames, navigating directories, and identifying file types. No prior experience required — just a terminal and persistence.

Rules

shared server	All players connect to the same machine. Passwords reset on every server restart.
no spoilers	Passwords change each run — sharing answers doesn't help.
read-only	Challenge files are owned by root. You can read them, not delete them.
no account	No registration. SSH in and start playing.
