To win £10,000 towards their prize fund and tokens, Housemates must pass this task. The problem is, they are not told what the task is, only that they will pass if the Pass Or Fail meter in the large task room reaches the ‘PASS’ mark.
Inside the task room are a number of props, puzzles and challenges, such as a padlock with 200 keys, milk bottles filled with water, a large knotted rope, a large bowl of custard and apples, a non-optical illusion etc, however to pass the task, all Housemates need to do is leave the room. Each time one Housemate leaves the room, the meter will move one step closer towards the pass mark. Housemates have up to four hours to complete this task.

The three rules are:
Housemates are strictly forbidden from tampering with the pass and fail meter.
Housemates are free to come and go from the task room as they wish.
Big Brother’s decision is final.
