Qix is a puzzle game where you guide a marker to draw rectangles and other objects in order to claim your territory. You can choose how fast or slow you want to draw, with slower speeds scoring more points. As you draw, you need to watch out for Qix, colored lines that move across the screen, as well as Sparks that travel around the border and along your own lines, and The Fuse, which moves along the line you're drawing.
The game requires strategy, as you need to balance speed with territory control. With each level cleared, you progress to the next one, trying to outmaneuver Qix and avoid its deadly edges. Will you be able to claim enough territory to reach the next level?
