Qix (1981) is Taito's abstract territory game, designed by Randy and Sandy Pfeiffer: draw lines to claim the screen while dodging the swirling Qix.
In Qix the player's marker leaves the screen's edge to draw lines across the empty field, and closing off an area claims it — the goal is to fill a set percentage of the screen. The Qix, a restless tangle of moving lines, destroys the marker if it touches an unfinished line, while Sparx patrol the borders. Lines drawn slowly score more than fast ones. The concept had no real precedent in the arcade and was later reworked in games such as Volfied.
Qix was designed by husband-and-wife team Randy and Sandy Pfeiffer at Taito America in 1981. Players drew lines to claim territory on the screen while avoiding the Qix — an abstract entity of spinning lines. The concept was entirely original with no precedent in arcade games. The game required a mental model completely different from shooting or racing games, and attracted a dedicated following among players who enjoyed its abstract puzzle quality.
