Why the explanation is the valuable part

Practice builds speed

Working an incident under a clock trains you to read dashboards and logs quickly, with nothing at stake.

Explanations build judgment

Seeing the shortest path to the root cause, and why the tempting theories were wrong, is how you start recognizing patterns.

Judgment is what gets noticed

Calm, structured debugging is what teams look for in on-call rotations, incident reviews and senior interviews.

Questions

Is the game really free?: Yes. Every weekly incident and the whole archive are free to play, with all the evidence, hints, the leaderboard and email alerts. You always see which of your answers were right or wrong. No account or card is needed to play.
What is in a full explanation?: The root cause in plain language, the correct answer to each question with the reasoning behind it, the ideal investigation step by step, the key clues, the red herrings, a timeline of the incident, the lessons to take to your own on-call, and links for going deeper.
Can I see one before paying?: Yes. Incident #1 includes its full explanation for everyone, so you can see exactly what you would get.
Can I cancel?: Any time, from your account page, in two clicks. You keep access until the end of the period you paid for. Explanations you bought one at a time stay yours.
Will my employer pay for it?: Often, yes: many teams have a training or learning budget. Every payment comes with a proper invoice by email that you can expense.
How are payments handled?: By Paddle, our payment partner and the merchant of record. Paddle takes cards, PayPal, Apple Pay and Google Pay, adds any sales tax or VAT that applies where you live, and sends the invoice. DevOpsdle never sees your card details.
