Anti-Slop CTF 2026

This CTF is designed around anti-AI and unsloppable challenges that resist agent automation and low-effort guessing. The problems aim to reward careful reasoning, persistence, and creative human intuition rather than generic agentic tooling output. Some challenges may be difficult, but they are intended to feel interesting, fair, and satisfying to work through. Expect puzzles that require understanding the underlying ideas, not just prompting harder.

Challenges might still be sloppable, but the spirit is not.
