Advent of Code

By midnight EST (UTC−05:00), 81 people had signed up for the event, going slightly over Wastl's planned 70-participant capacity.

[9] Participants are awarded one gold star for completing each part of a daily puzzle.

Each puzzle contains a fictional backstory that is the same for all participants, but each person receives a different piece of input data and should generate a different correct result.

[4] Some participants have used tools such as GitHub Copilot and ChatGPT to assist in solving the puzzles.

Wastl built almost the entire website himself, including the design, animations, prose, and puzzles.
