In 2016, the trophy for the most valuable police work was given to a traffic camera at Kehä I, when innovative tech students decorated as the “the police of the year”. This prank was universally amusing to everyone, including to the police themselves.

The Jäynä Finalé and prizes

The 34th Jäynä Competition reaches its peak at the Jäynä Finalé held the 22th April 2021. The wappu celebrators of Otaniemi are treated with recordings of the finalist jäynäs, various skits, quizzes and other exciting content. At the end of the Jäynä Finalé the judges choose the winners of the 34th Jäynä Competition, who take home amazing prizes to be published later. They are also given the honor to represent Otaniemi in the annual National Jäynä Competition! In addition to this all participating teams get to enjoy the Finalé at VIP seats.


A successful jäynä starts with a solid idea and careful background work. How to set up the jäynä? How do you assure the target? What’s the twist? How to make it fun?


Well done is half the victory: a winning idea comes to life with careful execution and a sprinkle of inspiration. What tools or other material do you need? How do you split roles within your team?


A successful jäynä turns into a winning jäynä with well-thought documentation so that the process and the feeling grips the crowd. You can document with audio, video, photos, or whatever comes to mind!


Finally all you need to do is to submit the spectacular jäynä to the competition and send it to the judges. The finalists are announced later in the spring, but all participants get to enjoy VIP seats at the Jäynä Finalé nevertheless.
