Jg is shorthand for jungle, the area of the map located between the three main lanes and filled with neutral monster camps. Because fog of war heavily covers these sections, navigating the jungle safely requires awareness of enemy movement and smart use of Map awareness. The player in the jungler role clears camps for gold and experience while choosing efficient routes to stay healthy and maintain tempo.
Beyond farming, the jungler is responsible for controlling major objectives like Dragon or Rift Herald and helping laners through well timed Ganks. Since jungle monsters are neutral until attacked, the jungler determines when and how to engage them based on team needs, lane states, and overall strategy. Their presence and pressure directly shape the match’s pacing, influencing rotations, skirmishes, and broader Macro decisions across the map.
