Houseguests enter a black box. They must search around for items and place them where they need to go. The houseguest(s) that get the most the quickest will win the competition.
In Big Brother 18, houseguests had to hold a button, and if not back in time, would have to leave the black box competition.
In Celebrity Big Brother 1 (US), houseguests had to crawl through a makeshift restaurant and try to make their way out in the fastest time.
In Big Brother 20 (US), houseguests had to search around for folders in order to escape. There was one less folder than there were people playing, so whoever was left without a folder received a punishment. One special folder would allow whoever finds it to advance to the other round, while any other folder would only spare the finder from the punishment.
On the following season, Big Brother 16, the competition was used as a Battle of the Block competition. Houseguests Christine Brecht and Donny Thompson won the competition, dethroning the HoH that had nominated them. However, Christine was trying to throw it so Donny really won it on his own.
Used as one of the opening night competitions on Big Brother 20 (US), half of the houseguests participated in this competition, with the loser being given a punishment. Angela Rummans won the competition, and advanced to the next round's Immunity Competition, while Kaycee Clark came in last place and was punished with a Unitard.
