The Only Sanderson Puzzle

NOTE: This puzzle has been altered to make it accessible for postsolvers. During the hunt, the tab marked "M" was initially unavailable. It was unlocked after any five of the previous subpuzzles were solved.

This puzzle may contain major Cosmere spoilers for books up to and including Rhythm of War.

We recommend setting Coppermind to its "Before 2022-2023 Secret Project details" state using the Time Machine. (Some small spoilers for currently published works, including Secret Project 3, may still be visible under these settings.)
