Same rules as dodgeball (which vary for everyone, so use your own dodgeball rules ), except there are small hockey nets used to get goals on. They are placed on each team's side or evenly spaced apart if you play in a circle.
The object of the game is to reach a certain number of goals per team by throwing a ball into the net. In addition to trying to score points, you try to get the other team's members out.
There are two ways to win:
1) Be the first team to reach the target number of points.
2) Get all of the other team's players out.
The reason it's called "European" dodgeball is because it is a mix of dodgeball and European handball.
