Question 1

Do I need an account?

Accepted Answer

No — every challenge and bug hunt runs without signup. Signing in is optional: with email/password or Google it syncs your completed challenges and badges across devices, and you can manage or delete the account any time from your profile page.

Question 2

Which locators should I use?

Accepted Answer

Every interactive element carries a stable id and data-testid — prefer those over text or CSS selectors that can change.

Question 3

Is the data deterministic?

Accepted Answer

Yes, with two loudly-labeled exceptions built to teach the failure mode: Challenging DOM's ids, and Notifications'/Dynamic Content's randomness.

Question 4

How do I speed up timer-driven challenges in CI?

Accepted Answer

Append ?delay=… to shorten waits on Dynamic Loading, Dynamic Controls, Tooltips, Obscured Elements, Streaming Feed and Session Timeout.
