Harcourt stated that the production team would decide who would be the right fit depending on who just left the game, acknowledging that with thirteen contestants, not all who were possible players end up on the show at all.

This includes sharing their age, relationship status, a short bio, and one photo to use as their profile picture.

Sometimes, either through rewards or passing a certain milestone, the players are allowed to upload another photo to their profile.

Depending on how high or low their average placement was, the player's ranking would determine if they became in influencer or not.
