[2] It is a two-player game played on a 6×6×6 hexagonal gameboard, and is notable for being the oldest known board game played on a board of hexagonal cells.

Players determine who moves first, then turns alternate.

The object of the game is to be first to maneuver one's queen to the central hex (the throne) at the center of the board, and surround her with all six of her guards.

In the Victorian era, sets were sold by wood turner Thos Sherwin, and Jaques and Son.
