If the match you are watching has a Show Director and they set up a vote, you will have the opportunity to vote on whom or where they should unleash his Power. It can be an inmate or a zone.

To vote, click on the inmate or the zone in the extension overlay in order to register your vote. You have a limited amount of time to vote so be quick! As soon as the countdown ends, all the votes are aggregated, and the Show Director power is applied to either the inmate or the zone that generated the most viewers votes.
