[2] The two contestants have only a limited time of three hours to complete all assigned tasks, after which the prize, in a brief case is removed.

Any "thumb drives" not located within the allotted time incur a penalty of €5,000 and less clues at the penultimate stage of the game.

Failure to find any of the "thumb drives" incurs a penalty of €15,000, but this still leaves €5,000 to each contestant for being "run all over town" for an afternoon.

Most contestants seen in the aired show are young and fit, in the 25 to 35-year-old age group and generally middle-class.

They are usually placed in coffee shops or cafes frequented by the target age and socio-economic group.

Upon answering the ringing, apparently lost 'phone, the contestant receives the response, "This is AVRO Broadcasting, do you wish to have a chance at winning €25,000, if so press "1" on this device, if not, just hang up."

Viewers never get to see those who hang up but it is obvious that this is part of the screening process which filters out senior citizens, minors or other "unsuitable" people.

Contestants are often seen in workplaces such as warehouses or docks where operating fork lift trucks are working or other industrial sites where heavy machinery is still in use.
