+
+> Queen's Guard, also known as Agon, is a strategic board game played on a hexagonal board consisting of 91 smaller hexagons, with a central hexagon known as the throne. The board features alternating colors of hexagons in rings, radiating from the throne. Each player has one queen piece and six guard pieces, which start in alternating positions along the outer ring of the board. Players take turns moving their pieces towards the center of the board, either forward or laterally. A player's piece can be captured by an opponent if it is surrounded on two sides in a straight line, and the captured piece must then be relocated to the outer ring. To win the game, a player must successfully maneuver their queen onto the throne while also surrounding it with all six of their guard pieces. Queen's Guard is a strategic game that requires careful planning and tactical thinking to achieve victory.
