It has been around since 1922 and originated in the USA. Roller derby is played by two teams of five members simultaneously skating on a circuit track. One in each team is called a jammer, wich is the player that are able to score for the team (recognisible by the star on the helmet). The other four members are called blockers.
Well, thats the basics of the game and initially it's very confusing. It's alot happening during a jam and it took me awhile to figure out what to focus on. But after a couple of jams I started to figure out what was happening and the game became much more interesting to watch.
In the end the two team had almost the same score and the game was settled in the final jam. The Gothenburg team finally won the game with the score 147 - 140. Cool with such an exiting game at my first time at a bout.
I was totally impressed by the Gothenburg jammer Mad Fish. She scored most points for Gothenburg and was a very forceful skater.
