Tafl games are a family of ancient Germanic and Celtic strategy board games played on a checkered or latticed gameboard with two armies of uneven numbers, representing variants of an early Scandinavian board game called tafl or hnefatafl in contemporary literature.Although the size of the board and the number of pieces varied, all games involved a distinctive 2:1 ratio of pieces, with the lesser side having a king-piece that started in the centre.
