Queens' Quarrel is one of the games that came with the disk of issue 37 of Compute!'s Gazette, released in July 1986. Based on a puzzle by Karl Friedrich Gauss, players need to place 8 haughty queens who have quarreled in a way that either piece is not adjacent to each other, whether it be horizontally, vertically or diagonally.
