In 1932 a board was found in a crannog in Ireland. It contained a 7 X 7 grid of holes, and was decorated with designs used in the 10th century. Many scholars believed it to be a Fidchell (also spelled Fithcheal, or Fitchneal) or "Brandubh" a game mentioned in early Irish legends, and related to Scandinavian Tafl games. These were the games of choice in Northern Europe prior to the introduction of Chess. The defenders win if the king escapes to the edge of the board, and the attackers win by surrounding the king.
The knotwork decoration is the manufacturers interpretation of carvings on the original board. To the best of our knowledge they are the only company to produce a game board directly based on the Ballinderry artifact
