Microsoft Puzzle Hunt

The Microsoft Puzzlehunt is a quasi-annual Microsoft tradition started in 1999. It is a puzzlehunt in the same vein as the MIT Mystery Hunt and has some similarity to The Game. The hunt is a team puzzle competition which challenges each team to solve a large number of original puzzles of all different kinds. The answers, when used in conjunction with the metapuzzle, lead to a hidden treasure concealed somewhere on the Microsoft campus. Teams spend the weekend solving original and unique puzzles, usually created by the team that won the last hunt. Puzzles may be anything from traditional puzzles like crosswords, word searches, cryptograms, jigsaw puzzles, word play and logic problems to wandering around campus to find landmarks or puzzles that have to be solved on location. Microsoft Puzzlehunt was founded by Bruce Leban, along with Roy Leban and Gordon Dow.

The Microsoft Puzzlehunt takes place over a weekend at the Microsoft campus in Redmond, Washington, usually lasting approximately 31 hours from beginning to end. In general, teams are no larger than 12, at least 4 must be current Microsoft employees, and at least 6 must be current or former employees.

Microsoft has a rich tradition of puzzle events, including Microsoft Puzzle Safari, College Puzzle Challenge, Microsoft Intern Puzzleday and Microsoft Iron Puzzler, but Microsoft Puzzlehunt remains the "main event" for puzzle solvers in the Microsoft community.

The opening round was a newspaper distributed immediately after the opening event, ending with the first meta. There were 8 meta puzzles, with the final one being six rebus puzzles (gotten from the intermediate six metas), which each fed into a final rebus meta puzzle. At the end of the hunt, it was learned that Captain Micropolis was really The Puzzler and the winning teams saved him from a fate worse than death.

A puzzle that had you build a quinoa-powered analog computer that produced a phone number.
*Landmarks: The top three teams finished the hunt separated by only 16 minutes. First hunt with automated web answer submission system. First hunt to have a dramatic end-of-hunt spectacle at the closing ceremonies (in previous hunts, end-of-hunt storyline was only seen by finishing teams).

A web interface built in Microsoft Silverlight which provided an immersive experience appropriate for the Tron theme.
