Rules

Don't Cheat.

No colluding across teams, no sharing writeups mid-hunt, no asking Discord for the flag. Get caught and you're on the naughty list, permanently.

Unlimited Answers. Finite Patience.

There's no hard cap on submissions, but spray-and-pray will get you rate-limited (or worse). Think, then type.

Don't Attack the Site.

None of the challenges require you to probe, DoS, or otherwise attack this website or its infrastructure. Solve the puzzles. Leave the platform alone.

No chadgippity, clawd, or jeminy.

LLMs are out. Don't try to be clever by switching to Grok either. The naughty list doesn't do brand loyalty.
