The housemates stand looking slightly confused as they are instructed by Big Brother to go into the garden, where they must not touch any of the equipment.

The 'roundabout' appears to be in the centre of the garden and is covered.

Housemates are currently being informed that the prize fund can decrease if they fail the task.

The first part of the challenge involves markers placed within the garden, numbered from 1 to 11. Housemates must now rate themselves from 1 to 11 on the basis of their intelligence. With 1 being the most intelligent.
