３Quarter, or 3Qurter, depending on if you believe the packaging and English language or the game title screen, is a Qix clone for the PC-8001. I've actually played very little true Qix in my life, my introduction to the game was a clone for my Commodore 64 called Kwixx by Keypunch Software. I only recently played the original arcade game about a week ago, for the first time. But in any event, a very fun game where you have to cover up 75% of the screen by drawing lines, while avoiding a monster floating in the free space, and sparks that travel along the borders of the screen and the lines you've drawn.
