    Have You Taken My Challenge? ►
    Loyal Theorists, I've been keeping secrets from you. Well, actually I've been creating riddles and codes leading to secret gates for you to find - and find you have! So many of you have participated in the Game Theory ARG we started oh so many months ago. Today I want to peel back the layers of this mystery and show you exactly what I've been working on. This is how it all came together and how you can still solve it before it ends. Get ready to open the gates.
