How to use the archive for Wed, January 7, 2026
Date archive pages are useful because they keep one exact historical puzzle accessible while still connecting to the rest of the learning system.
A fixed reference point
When a past puzzle is preserved under a stable route, you can replay it later with better habits and measure the difference in your process.
That is valuable for improvement because the board itself stays constant while your solving changes.
Difficulty links stay close
From the date overview, you can move across all four difficulties for the same day, which keeps archive navigation efficient and meaningful.
The board stays first
The archive page keeps the playable board at the center while still giving you enough context to replay the date with confidence.
