 Friis’ description shows that the king piece unique to this tâb-type game had by then been invented, but he makes no mention of queens or for that matter "king’s children".However, the oldest existing sáhkku board (1876) features markings that indicate the place where the queens are set in "Lágesvuotna sáhkku", although the set does not include the actual pieces.The oldest existing complete sáhkku set, donated to a museum by Isak Saba in 1906 (depicted at the top of this article), includes soldiers, the king, three dice and a board with markings for where to place the king and possibly queens.
