I haven't got the foggiest of ideas what it is, but reading up on Qix (pronounced 'Kicks'), it's plain to see that this game is unlike any other I've played from this list so far. It doesn't involve shooting anything, it doesn't have any real world analog, but it requires quick thinking and reflexes, as well as a bit of strategy and luck. It's a fast paced puzzler of sorts.
The aim of the game is to fence off sections of the playing field, enough to block out more than 75%. You can draw fast or slow, with slower sections - marked in red - scoring you more points.
That would be a dull game were it not for the Qix, Sparks, and your own stupidity getting in the way of things. The Qix is a kind of spiralling, dancing, mess of a threat. Sometimes it hangs out well away from you before expanding and reaching right where you don't want it to. If it touches you, that's one life down.
The Sparks travel along the available playing field, and if they catch up to you, it's another life down. It's best to get moving before they arrive, even if it's just to avoid them with a small section of the playing field.
Finally, appropriately for a three life format, is your own foolishness. If you dawdle while drawing, your line becomes a fuse and you don't want the fuse to run out or that's one more life down. If you get yourself into a bit of a pickle, or a 'spiral death trap' as the introduction calls it, you're done for. Go home, you've lost all your lives.
