What is quickplay league

Quickplay League is not a known or official term in the League of Legends (LoL) universe. The search results suggest that there are no direct matches for "Quickplay League of Legends".

However, Riot Games, the developer of League of Legends, does have a mode called "Flex Queue" which is a mix of Ranked Flex and Normal games, allowing players to play with a team of any size. This mode is often referred to as "Quick Play" in some online forums and communities, but this term is not officially recognized by Riot Games.

It is possible that you may be referring to a custom or community-created game mode, or a third-party tournament or event that is not affiliated with Riot Games or the official League of Legends esports scene.
