puzzle hunt

A puzzlehunt puzzle usually has no direct instructions for how to solve it, but instead requires solvers to deduce the approach to solving it. The method of solving may be hinted by the puzzle's title and its "flavor text". Some puzzles may involve elements of familiar puzzle types such as crossword puzzles, jigsaw puzzles, cryptograms, and others, but they often have an additional twist beyond the usual structures of such puzzles that solvers must discover. Other puzzles may have innovative structures whose mechanics solvers must work out from scratch.

The solution to a puzzlehunt puzzle is generally a word or phrase. The process of deriving the final answer once the main part of a puzzle has been solved is known as "extraction". Extracting the answer may involve, for example, selecting certain letters from words or phrases clued in the main part of the puzzle, interpreting the solution to the main puzzle in terms of encoding schemes such as Braille or Morse code, or reapplying to the output of the main puzzle the gimmick used to solve the main puzzle and produce that output.

Groups of puzzles in a puzzle hunt are often connected by a metapuzzle, which is a puzzle based on combining or comparing the answers of other ("feeder") puzzles. For some metapuzzles (sometimes called "shell" metapuzzles), the answers to the feeder puzzles must be incorporated into a puzzle structure that is separately provided to solvers; for others, ("pure" metapuzzles), the feeder puzzle answers alone provide all the information needed to solve the metapuzzle.{{cite web |date=2019-09-02 |title=Introduction to Puzzlehunts |url=https://blog.vero.site/post/puzzlehunts |website=blog.vero.site}}

Puzzlehunts based in a specific location may involve "run-around" components, where solvers are directed to travel to specific sites in order to solve certain puzzles.

Participants often use social chats like Discord and spreadsheets like Google Sheets to collaborate and organize information. Many puzzle hunts involve online information, so solvers often use the internet to gather information.

Additionally, some online tools are used more specifically for puzzle hunts and similar activities. Pattern matching tools like Nutrimatic allow for search and completion for words or phrases.{{cite web |date=29 Jan 2025 |title=Nutrimatic Usage Guide |url=https://nutrimatic.org/usage.html |website=nutrimatic.org}}

One of the earliest examples of puzzle hunts is the MIT Mystery Hunt, started by Brad Schaefer in 1981. Later hunts in the MIT Mystery Hunt incorporate a cohesive theme across the puzzles.

As puzzle hunts grew in popularity and scale, other universities like Melbourne University and Carnegie Mellon University created their own version of a puzzlehunt. Puzzlehunt writers also incorporate new ways of organizing rounds. Foggy Brume started the P&A Magazine, which incorporates puzzlehunt puzzles in a magazine.{{cite web |title=P&A Magazine | Frequently Asked Questions |url=https://www.pandamagazine.com/index.php?f=Faq |website=pandamagazine.com}}

Further development of the internet allowed for puzzles to make use of digital mediums, including videos and games. Some teams both compete in puzzle hunts and regularly create their online puzzle hunts. These teams also make open-source hunt frameworks like gph-site that allow even more groups to host online puzzle hunts. Many of the hunts are shared on Puzzle Hunt Calendar, developed by Dan Egnor.{{Cite web |last=Egnor |first=Dan |title=Puzzle Hunt Calendar |url=https://puzzlehuntcalendar.com/ |website=puzzlehuntcalendar.com}}

Individuals or teams can take part in a puzzle hunt-style challenge using software such as ClueKeeper on their smartphones. An individual hunt is purchased, downloaded, and played at the player's convenience. Such hunts are typically not timed and offer no prize except the enjoyment of playing and the satisfaction of solving the challenge. Most are tied to a particular location and require walking from place to place as the puzzles are solved,{{cite news|url=https://kobi5.com/news/escape-ashland-offers-outdoor-puzzle-hunt-safe-social-distancing-128322/|title=Escape Ashland offers outdoor puzzle hunt, safe social distancing|last=Furuichi|first=Miles|date=May 11, 2020|work=KOBI-5|accessdate=13 July 2020}}{{cite news|url=https://www.wtvy.com/content/news/Escape-Enterprise-offering-new-experience-to-social-distance-571326661.html|title=Escape Enterprise offering new experience to social distance|last=Brooks|first=Nick|date=June 17, 2020|work=WTVY|accessdate=13 July 2020}} but some are designed to be played at home.
