Qix

Qix is a fixed-screen action-puzzle game in which the player controls a small marker moving along the boundary of an initially empty rectangular playfield. The objective is to claim a required percentage of the screen by drawing orthogonal lines, known as Stix, through the unclaimed area. When a line reconnects with an existing boundary, the section that does not contain the Qix is filled in and added to the player’s territory.

Two drawing speeds are available. Fast Draw completes a Stix more quickly and reduces the time spent exposed, while Slow Draw is riskier but awards twice as many points for the area enclosed. Larger regions are generally worth more, and claiming territory beyond the minimum required to complete a stage provides an additional bonus.
