Strange sport in Iceland - video and women only

Today there was a womens sport tournement in Reykjavik.
It is some sort of a ball thing,where they use a single ball,and try to hit another player.
Since i am of the " male " kind, then the rules might be to complicated for me to understand.
But they where playing today ,and the weather does not matter .
It was cold and windy.
But they had a great time playng, and it was fun to watch.
And sometimes ,as you can see on the video , judges had to talk , about ruling .
