The Loading Screen is a pre-game screen where summoners wait for everyone's game to be ready to start.

On the loading screen both teams can see other summoner's names, champion splash arts and summoner spells. You can only see Champion Mastery and player rank of players in your own team.

The summoner can also see its ping. So while the loading screen is active, he/she can solve problems before the game starts.

He/she can use its computer even if the loading screen is in full screen, the user can use Alt + Tab on Windows to move to other windows. If there's not any other window, he/she can use Windows + D to get to the desktop.
