How are points scored in roller derby?

Points in roller derby are scored primarily by the jammers, who are designated players representing each team. The process involves the jammers skating through the pack of opposing players after making an initial pass. Once they clear the pack, each subsequent opposing skater they lap earns their team one point. This element of the game emphasizes the jammers' skill in maneuvering around blockers while maintaining speed and control.

The other options touch on different aspects of the game but do not accurately describe the scoring mechanism. Blockers focus on obstructing the opposing jammer but do not score points themselves; penalties affect gameplay strategy and can impact the number of available players on the track, but they do not directly contribute to scoring; and scoring cannot occur from the penalty box, as players in the box are unable to contribute to point accumulation.
