Mystery Hunt 2023 Team Statistics

2023 January 24

With MIT Mystery Hunt 2023 (list of puzzles, kickoff video, wrap up video, global stats) coming to close yesterday – apparently the second-longest MIT mystery hunt – I wanted to look back at the puzzle solving on my team I’m not a planet either. While mystery hunt was back to being in person after having been online for two years, about half of the team was remote, and we retained the fully remote tech stack for team communication and coordination.

As I did last year and the year before, I was on the tech team and so recorded our puzzle solving statistics. Mercifully, the tech worked quite smoothly this year: automated puzzle scraping was up within 40 minutes of hunt start, and there were no significant hiccups1the worst was a few minutes delay in making slack channels when some puzzles with no latin characters in their title tripped the automated system.

First, how many puzzles were available to our team, and how many of them had been solved at any time:

Like all images here, click to zoom. Note that this includes event puzzles. The diurnal cycle in puzzle solving is evident, as is the several big timed unlocks of puzzles

Below is the list of every puzzle solved by the team. In total we gained access to 93 puzzles, of which we solved 35.

Note that later puzzles were solved by fewer, better teams, and thus the median solve times go down relative to their difficulty.

Quality Assurance had by far the most person-time invested, at 62h, with the two metas The Cafe and Nuclear Words also being quite high. A list of all unsolved puzzles in which we invested at least 3 hours of time:

Though note that much of time spent on Much Ado About Nothing was actually finding the entrance to the Puzzle Factory, including a collaborative jigsaw puzzle; I didn’t notice people spending much time on the puzzle itself.

Unlike in previous years which had quite a few easier puzzles that we solved quickly, this year the distribution of solve times was somewhat flat:

Conversely, though, the slowest puzzle took us only 30 hours, whereas in the past there were puzzles that took the whole weekend to complete (cough Voltage Controlled).

  1. the worst was a few minutes delay in making slack channels when some puzzles with no latin characters in their title tripped the automated system↩︎

  2. because at first Ceres was checking for updates every 3 minutes, which was later increased to every minute↩︎
