Volume I: Beginnings (2021)

Evan Chen, Isabella Quan, Serena An, Sanjana Das

The 2021 hunt consisted of two rounds, Chapter 0 and Chapter 1.

  • Chapter 0 was a single puzzle that unlocked the main event, but the puzzle's post-hunt adaptation is less thematic, so personally I would just skip through it for the story.
  • Chapter 1 is a one-round hunt with some feeder puzzles and a metapuzzle.

Note that some puzzles will assume familiarity with the content of the 2021 USA Math Olympiad.

Chapter 0: Online World Map
Chapter 1: Map of Secret Puzzles
