For 25 years and 48 seasons, Jeff Probst has been guiding the contestants of Survivor through the perils of living off of the land. But if competitors want to bring home the $1 million prize, they have to follow a lot of rules outlined in a very detailed contract.

It’s one of the reasons we bring alternates, is to have our own insurance.” So...what exactly are those rules?
