Professional League of Legends is played as a five-on-five team game, with each player assigned to one of five distinct roles. Understanding what each role does — and how they work together — is essential for following competitive LoL.
The Top Laner plays alone in the top side of the map, typically on tanky or bruiser champions that can absorb damage and split push. In competitive play, top laners are expected to hold their lane independently, play weakside (without jungle attention), and serve as a frontline in teamfights. Great top laners create pressure through split pushing, forcing the enemy team to send multiple players to deal with them.
The Jungler does not lane — instead, they farm neutral monster camps in the jungle and create advantages by ganking (ambushing) lanes. Junglers control the two most important neutral objectives: Dragon (grants team-wide buffs) and Baron Nashor (grants a powerful siege buff). The Jungler is often considered the "tempo setter" of the team, deciding which lanes to prioritize and when to force fights around objectives.
The Mid Laner plays in the center of the map, giving them the shortest rotation time to either side lane. Mid Laners typically play high-damage mages or assassins and are often the primary playmakers on a team. Because of their central position, they frequently roam to help the Jungler contest objectives or gank side lanes. Mid lane has the widest champion diversity of any role.
The ADC (Attack Damage Carry) shares the bot lane with the Support. ADCs play ranged champions that deal sustained physical damage through auto-attacks. They are the weakest role in the early game but scale into the primary damage source in late-game teamfights. Positioning is the most important skill for ADCs — they must deal maximum damage while staying out of range of enemy threats.
The Support shares the bot lane with the ADC and is responsible for vision control, protecting the ADC, and creating plays. Supports buy control wards and place vision around key areas of the map, denying the enemy team information. In teamfights, supports either peel (protect) their carries with shields and heals, or engage the enemy team with crowd control abilities. Support is the most diverse role in terms of playstyle.
Mid-Jungle synergy is often called the most important duo in competitive LoL. The Mid Laner and Jungler coordinate to invade the enemy jungle, secure Rift Scuttler vision, and set up 2v2 skirmishes. Teams with strong mid-jungle synergy control the pace of the game.
Bot lane 2v2 dynamics between ADC-Support duos determine which team controls Dragon. The Support’s ability to create leads in lane through roam timings and vision directly impacts whether the team secures early Dragon stacks.
Weakside vs. strongside is a fundamental concept. Teams decide which side of the map to invest resources into (strongside) and which laner must survive without help (weakside). Top Laners most commonly play weakside, while the Jungler focuses on the bot-side of the map to contest Dragon.

The five roles are Top Laner, Jungler, Mid Laner, ADC (Attack Damage Carry, also called Bot Carry), and Support. Each player on a five-person team fills one of these roles, and teams draft champion compositions around how these roles interact.
Jungle and Mid are generally considered the highest-impact roles in professional play because they have the most influence over the map. Junglers control objectives (Dragon, Baron) and create advantages through ganks, while Mid Laners can roam to both side lanes. However, every role can be game-deciding in the right context.
The ADC (Attack Damage Carry) plays in the bot lane with the Support. Their job is to farm safely in the early game and scale into a late-game damage dealer. In teamfights, the ADC provides sustained physical damage from range. Famous ADC players include Ruler, Gumayusi, and Viper.
Supports control vision (wards), protect the ADC in lane, and often initiate teamfights with crowd control abilities. Great supports enable their entire team — they set up plays, track the enemy jungler, and control the pace of the bot lane. Support is widely considered the most underrated role in professional play.
