Krulbollen is a traditional popular sport that is very alive in Zeeuws-Vlaanderen. The game adds up to rolling a flat disc, in the shape of a cheese, the krulbol (curve boll), over a distance of 23 feet, as close as possible to a stick that has been placed in the ground, the staak. Because of the one-sided rounding of the krulbol it takes an oblong orbit when thrown. The sport owes its name to this phenomenon: krul means curve. Two teams of one to four people play against each other. The game is played on a sand course of 37 feet long and 11 feet wide, with two sticks, placed 23 feet apart.
There are various throwing techniques, like bollen (bolling): rolling the krulbol as close as possible to the stick and schieten (shooting): to make room for your teammate if the opponent is too close to the stick. In Dutch Flanders different competitions are played. By putting down the history, organising tournaments and promoting krulbollen with young people, the clubs try to keep krulbollen alive.
