Hnefatafl: Viking Chess

Step into the firelit great halls of the Vikings and master the legendary King's Table.

Played across Scandinavia and the British Isles as early as 400 AD and immortalized in ancient Norse sagas, Hnefatafl (pronounced "nef-ah-tah-ful") was the strategic board game of Viking chieftains and jarls long before chess reached Northern Europe.

Excavated from famous archaeological ship burials at Gokstad and Oseberg, and recorded in 1732 during Carl Linnaeus's Lapland journey, Hnefatafl is history's premier game of asymmetric siege warfare. An outnumbered defending king and his guard must break free from a surrounding army of raiders.

1. THE SETUP: The King stands on the central Throne surrounded by 12 defenders. 24 attackers occupy the board edges.
2. MOVEMENT: All pieces move like Rooks in chess—any number of empty squares horizontally or vertically.
3. CUSTODIAN CAPTURE: Sandwich an enemy piece between two friendly pieces orthogonally to capture and remove it.
4. SANCTUARY HAVENS: The 4 corner squares and throne are sacred. Only the King may land on them. Corner sanctuaries also act as hostile anvils for captures.
5. VICTORY:
- Defenders win when the King reaches any of the 4 corner sanctuary squares.
- Attackers win when they capture the King by surrounding him on all 4 sides.
