It is the city's tourism manager Mari Bareksten who has brought as many as 30 businesses, both attractions, museums, galleries, shops and eateries, on the pole hunt.
They have had a specially made Christmas pole made by Drøbak microcarpentry outside their company, and where people can scan a QR code with their mobile in the same way as on a pole hunt, get points and where they will then find more information that the trader has posted.
Whether it's good Christmas offers, current art exhibitions or other exciting information about the place.
