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 to draw fast or slow, but drawing slowly will give you more points. As you draw, you need to watch out for Qix , a series of colored lines that move across the screen. You also have to avoid the Sparks who travel around the border, as well as any lines you've made and The Fuse, who moves along the line you're drawing. Your goal is to claim enough territory before it's all claimed by Qix . Once you've done that, you can move on to the next level.
The gameplay in Qix requires strategy and timing. You need to balance speed and accuracy as you draw your rectangles, while also keeping an eye out for the moving obstacles. As you progress through the levels, the game gets faster and more challenging, but with practice, you can become a master of claiming territory.
