The aim of Kubb is to knock over wooden blocks (kubbs) by throwing wooden batons (kastpinnar) at them.
Play takes place on a small rectangular playing field, known as a “pitch”. “Kubbs” are placed at both ends of the pitch, and the “king”, a larger wooden block, is placed in the middle of the pitch. The ultimate objective of the game is to knock over the “kubbs” on the opposing side of the pitch, and then to knock over the “king”, before the opponent does.
