The arcade
Seven games, each drilling one thing beginners get wrong — in interviews and at 3 a.m. Nothing to install, nothing to sign up for, and every wrong answer comes with the reason.

Pipeline Builder
A push just landed on main. Put the stages in the order a real deployment runs them. Tap a stage to place it in the next empty slot, tap it again to take it back — or drag, if you prefer.

Container or VM?
Sixteen statements. Tap one to pick it up, then tap the bin it belongs in. This is the question almost every DevOps interview opens with.

YAML Doctor
Each patient is a manifest that the cluster (or the CI runner) has rejected. Click the one line that is wrong. Indentation matters — read it like a machine would.

Incident Room
03:14. Checkout is failing for about a third of users and your phone is buzzing. Every action costs minutes. Close the incident quickly — without making it worse.

Tool Match
Eight tools, eight jobs, all face down. Find the pairs. Knowing which tool solves which problem is more useful than knowing any single tool deeply.

Interview Blitz
Forty-one questions from real first-round DevOps interviews, twenty seconds each. Wrong answers explain themselves, so a bad run is still a study session.
