League of Legends (LoL), commonly referred to as League, is a multiplayer online battle arena video game developed and published by Riot Games. Inspired by Defense of the Ancients, a custom map for Warcraft III, Riot's founders sought to develop a stand-alone game in the same genre. Since its release in October 2009, League has been free-to-play and is monetized through purchasable character customization. The game is available for Windows and macOS. In the game, two teams of five players battle in player-versus-player combat, each team occupying and defending their half of the map.
