In League of Legends, the player who is called a "summoner" selects a “champion” from a pool of 154 (As of May 2021) possible choices, each with their own set of unique abilities. Each player plays in a team with 4 other summoners against another 5 person team. The goal of the team is to make it to the opposite team’s base, called a "nexus", and destroy it in one of 3 battle arenas, called maps. However, to accomplish this, teams must first destroy 3 "towers" and an "inhibitor" in at least one "lane". The Nexus also spawns AI controlled minions for each team, that move forward and attack the first enemy champion, minion or turret they see.The most popular map, Summoner's Rift, is split into three lanes that each have three turrets and an inhibitor. Players can kill minions, or other enemy players to gain gold which can be spent on items to make their champion stronger.
