So, yes. This Perplex City game that I kept writing about on my blog.
A two-and-a-half year hunt for a buried metal cube, somewhere on Earth. More than 50,000 players. A prize of £100,000 or $200,000.
I won it.
Like any ARG, for most of the game it was a community effort. Many smart, committed players moved us all forward, until a few of us got the chance to sprint for the line.
Here are some pages and links about what happened then (or go to Firebox to get started with season two).
