The Mystical Magical Billiard Ball Tabletop Role-Playing Game Resolution System is a tongue-in-cheek, double-sided brochure-sized role-playing game designed to pick up and play almost immediately! Use a couple of tables to cobble together a plot idea, then use pre-made or original characters to solve whatever problems that are plaguing them!
And yes, you can, in fact, use one of those fortune-telling billiard balls (however, you can also use 2 six-sided dice, should you lack that very specific kind of soothsaying orb).
