Kyykkä (aka Finnish skittles) is a centuries old game of Karelian origin. The aim in Finnish skittles is to throw wooden skittle bats at skittles, trying to remove them from the play square using as few throws as possible.
This is how Wikipedia's page about kyykkä begins. Today we had the world cup at the parking lot in front of the University of Oulu, were, apparently, 400 students gathered to play it.
Since I live quite near to the university, I was woken up by the (lovely?) sound of tens of wooden bat. At that point I decided to take my camera and take some pictures of the event.
