Joom-ball
this fist-sized, ruby-red ball was part of a life-or-death game of chance which was played on the planet Serpine. The joom-ball is rolled down a spiral chute until it goes through a random hole. Depending on the hole it falls through, the joom-ball will determine the outcome of the game. The being who rolled the joom-ball down the spiral chute had to abide by the final outcome, which could mean total forfeiture of wealth, property, or life.
