The group were instructed this afternoon to privately complete a survey on their fellow inmates, where each person would be ranked in terms of likeability, honesty, intelligence, attractiveness, entertainment value and popularity.
Each housemate was then given a percentage rating for each category based on the results, which were covered up on giant top trumps card outfits.
After being split into a red group - consisting of Aaron, Tom, Faye, Harry, Alex and Mark - and a blue group - featuring Anton, Louise, Heaven, Aden, Maisy and Jay - housemates took it in turns to randomly select their opponent and choose a category they believed they would score higher in, with a point being awarded to the victorious team.
Watch a preview of the 'Top Chumps' task below:
Once all housemates squared off, Big Brother announced that the red team had collected the most points and declared them winners of the task.
As a reward, Aaron, Tom, Faye, Harry, Alex and Mark tonight enjoyed a picnic of pizza, beer and sweet treats in the garden while the rest of the group looked on.
