We on Floorpi really like doing puzzles. We participate in lots of puzzle hunts, including Mystery Hunt, Palantir, CBC, Dash, BAPHL, and PANDA Magazine. Many on hall also enjoy playing trivia games (Sporcle, Quiz Bowl) and doing logic puzzles (US Puzzle Championship, Nikoli, Logic Masters India, Professor Layton).

floorpi-puzzle, created in 2013, is the primary mailing list used to announce and discuss puzzles.

Galactic Puzzle Hunt

The inaugural Galactic Puzzle Hunt, a vaguely Australian-style puzzle hunt written by the generalized floorpi Mystery Hunt team ✈✈✈Galactic Trendsetters✈✈✈, occurred on March 14, 2017! A total of 282 teams solved at least one puzzle, 27 teams solved the final metapuzzle, 19 teams solved all the puzzles, and 4 teams solved all the puzzles with no hints within 24 hours of the puzzles' release times. The puzzles are still available online and we hope you enjoy them.

The second Galactic Puzzle Hunt occurred starting March 16, 2018! A staggering 447 teams solved at least one puzzle, 45 teams completed the hunt, 28 teams solved all puzzles, and 5 teams completed the hunt within 3 days (before hints were released).

The third Galactic Puzzle Hunt occurred starting March 15, 2019! 505 teams solved at least one puzzle, 30 teams completed the hunt, and 18 teams solved all puzzles.

GPH was not run in 2020 because Galactic was writing the 2021 Mystery Hunt.

The fourth Galactic Puzzle Hunt occurred starting July 23, 2021! 623 teams solved at least one puzzle, 76 teams completed the hunt, and 72 teams solved all puzzles.

Mystery Hunt

Floorpi has competed in the MIT Mystery Hunt during IAP for many years, often joined by alumni and friends of hall. Historically, our team size has usually been somewhere in the 20–40 range, but today team sizes reach 60–80 and include increasingly generalized pizens. Hunting used to take place in the lounges and residents' rooms, but nowadays is based in an MIT classroom. Past hall teams were named "✈✈✈Galactic Trendsetters✈✈✈" (2013), "Occupy Leisure Station" (2012), and "Desert Catbus" (2011).

The Floorpi team has been called ✈✈✈Galactic Trendsetters✈✈✈ by maximum-majority voting for 2015, 2016, and 2017. It was also called that in 2018; I don't even remember if we voted. It is also called that in 2019 by sketchy range voting. In 2020, we didn't even vote.

In case it is not clear, "Galactic Trendsetters" is the name of a pretty good card in the board game Race for the Galaxy (a world that costs 5, gives 3 VP, and consumes one arbitrary resource in stage IV for +2 VP), which has since appeared in various other board games.

In the past there were a fairly significant number of Mathcampers on hall, and they often hunted with Manic Sages, who won in 2012 and wrote the 2013 hunt. In 2013, a number of hall members also hunted with Palindrome, placing 2nd.
