The Brain is divided into six zones,[2] each corresponding to a different category: Logic, Memory, Orientation, Observation, Language, and Multi-Tasking.
[1] A zone is chosen at random, and the captain selects one team member to play two challenges related to it.
In the final, the team attempts to win up to £3,000 cash by answering questions similar to those faced in the individual challenges, but in a random order.
If all four members complete their questions before the clock reaches two minutes, they win the entire jackpot; otherwise, the game continues and the prize begins to decrease by £25 per second.
[1] Ian Wolf of On The Box described it as "perfectly enjoyable" but at the same time lamented the asininity of the questions being posed by The Brain, further berating its low prize fund of just £750 per person.
