The ‘’Viking track’’ preferred by Borvo posits that west-faring Norse seafarers learnt the game in the south, adapted it to daldøs, and introduced the game to the Sámi, who again made sáhkku from that basis. If this is to have happened in the Viking Age, táb-type games must be older than what written sources indicate. Depaulis adds to Borvo’s ‘’Viking track’’ theory by pointing to relationships between the Western Vikings (of contemporary Denmark and Norway) and Islamic Spain during the 800s, although this again presupposes that tâb is older than what written sources indicate. Borvo notes that the absence of sáhkku and daldøs traditions on the long stretch of coastline between Jæren in the south and Ivguvuotna in the north does not speak in favor of this theory, or indeed any theory presupposing that tâb-type games were at one point played along the entire western coast of Scandinavia. He speculates that the game may have died out south of Ivgovuotna because it was only in the far north that the Coast Sámi made certain innovations to the game that made it interesting enough to keep playing for centuries (i.e. the king and king’s children, the increased freedom of pieces to move). This explanation presses the question of why the less “exciting” version, daldøs, did survive in southern Scandinavia.
