## What is Sixth Chain?

Each challenge presents a closed set of entities and a fixed set of real-world connections. Every connection links exactly two entities - and only one complete chain is valid.

There are no trick answers, no wordplay, and no guesswork. Progress comes from elimination, contradiction, and careful deduction. One incorrect link breaks the entire chain.

Puzzles span multiple knowledge domains, rewarding players who enjoy structured thinking, logical certainty, and clean conclusions. New challenges are added regularly.

If you enjoy puzzles that reward clear thinking and decisive reasoning, Sixth Chain is built for you.
