How Completed Challenges Work
Archive Rules and Structure
The Completed Challenges section stores older challenges that have officially finished.
These threads are kept for learning, reference, and review.
This archive lets members:
• Look back at earlier challenges
• Study fully worked solutions
• Compare their attempts with final answers
• Learn how solutions are constructed
1. When a Challenge Becomes “Completed”
A challenge is moved into this archive when:
• Enough members have attempted it
• The challenge has run long enough
• The moderator decides to retire it
• An official solution has been written
Once this happens, the challenge thread is:
• Closed so no new replies can be added
• Updated with the final answer
• Moved to the Completed Challenges section
2. Who Can Post Here?
Only staff can create new threads in this archive.
Members can read, study, and learn from every archived solution.
3. Purpose of the Archive
This section exists to help members:
• Understand how challenges are solved
• See examples of high-quality reasoning
• Review problems they may have missed
• Build confidence before attempting new challenges
4. Notes for Learners
The solutions posted here are final.
They are meant for learning — not for debate or correction.
If you have questions about a solution, post in the main Challenge Arena, not here.
5. Welcome to the Archive of Reasoning
Challenge.
Learn.

This archive grows as the community grows.
