Mathcamp Puzzle Hunt

In 2002, I ran a mini-puzzle hunt at Mathcamp, in the (successful!) hope that it would encourage a Mathcamp team for the MIT Mystery Hunt. As they often do at Mathcamp, the tradition stuck. Here are the Mathcamp puzzle hunts:

• 2002: Who Stole all the Chalk at Mathcamp?
• 2003: Kill Dr. Lucky (by Team Horseradish)
• 2004: The Search for the Conflict-Free Schedule (by the Secret Society of Zec)
