Once upon a time in Survivor...
During this event the staff will let you know with an announcement in the room the "flavour of the day": a sentence, an image or a simple word that will be the reference point for all the hosts who want to participate in the event during the day. The staff will award double points to all the hosts who will incorporate the "flavour of the day" in their game in an effective way.
Example of an host worth double points:
The game in the example is a real game hosted by Rainshaft during the first Hosting Day ever.
Note that roomauth are not obligated to give double points if your host does not make a good faith effort at incorporating the flavour (e.g. don't just reference it once in one battle, and then never again.) However, feel free to interpret the flavour in your own way!
