CMU Puzzle Hunt

CMU Puzzle Hunt is a biannual puzzle hunt run by Puzzle Hunt CMU, a student organization at Carnegie Mellon University. In most years since 2007, Puzzle Hunt CMU has run two puzzle hunts, one in the spring semester and one in the fall semester. Hunts typically have around 20 puzzles, with a team size limit of 6; they typically lasted 8 hours each until 2020, when they were made about a day long each to accommodate non-local solvers. CMU Puzzle Hunt is typically aimed at novice to intermediate solvers.

Previously, the CMU Puzzle Hunt was known as the KGB Puzzlehunt, and was organized by members of the student organization of the same name. Originally it was an internal event for KGB members, but gradually became more popular to other CMU students as well. The name was changed sometime between 2012 and 2013.
