Hnefatafl - the Strategic Board Game of the Vikings

In case you're unfamiliar with the site or the game, Sten Helmfrid has gathered a wealth of information on the Norse game of tafl and its many variants. Kings, nobles, and war leaders were expected to be well-versed in this game and its strategies, and the gods themselves are recorded as playing it in Voluspa. Not only to learn more about the Norse and Germanic peoples, but also gain a special insight into their history and politics, you would do well to visit this site.
