This medieval Scandinavian strategy game was a cultural staple, much like chess in its time. It features several variants that change gameplay: board sizes range from 7x7 to 13x13, victory can be achieved by moving the king to the board's edge or corner, and encirclement rules vary—requiring the king to be surrounded from two or four sides. The number of attacking (black) and defending (white) pieces also differs across versions. Players can compete against AI, a local opponent on the same device, or online in multiplayer mode. Black, the attacking side, always moves first. Turns alternate, with all pieces moving vertically or horizontally any number of spaces. The blend of tactical depth and historical charm makes it a timeless classic.
