Knattleikr is an olden game that is known to have been played by Vikings of Iceland. No one knows the exact rules of the game today but there is a little information about the rules of the game that was played once.
For playing Knattleikr, players were divided into the teams. The game was played with a hard ball. Players used stick to hit the ball and hands were also used for the same purpose. In order to fight for the ball, body contact was permitted and the strongest team had more chances to win therefore.
Tournaments were arranged and a large number of spectators came to watch the game. Every team had a captain. The game was played from morning till night, such was the long duration of the game. There were penalties along with a penalty box.
The playing field was an ice covered surface. It is conjectured that the Vikings might have made use of sand or tar under their boots for the purpose of traction.
It is reenacted today by Norse culture enthusiasts. This game is also played in Brandeis University, Providence College and Yale University. In April 2007, the first New England intercollegiate knattleikr competition was played.
As per the New England Viking reenactment group, the game might not be safe and a player is permitted to leave the game at any time.
