The document introduces a new sport called DevilRoller that requires no expensive equipment and can be played using only a pencil or toilet paper. It works the entire body by having players roll themselves like a devil as fast as they can for as many repetitions as possible to build muscle and stay healthy, while competing with friends, family or in teams to see who can do the most rolls. Players are encouraged to challenge themselves, keep track of their scores, and get creative with their rolling objects.
