ObieGame

A treasure hunt/ARG combining online riddles and puzzles with real-world experiences (clues placed in stores or the library; handoffs from real people). Started mysteriously in spring 2004. 2006 and 2007 installments both involved over 150 student players.

Prizes are usually gift certificates to downtown businesses (team's choice) and the winners in 2007 snagged a $200 top prize.
