Mini-games + leaderboards

So I thought of an idea of an alternate form of Rotating Game Mode, in the from of mini-games. These are designed to be single player or 2-player but still have some kind of leaderboard to encourage competition. I was inspired by the "Sion Speedway" and "Mundo Dodgeball". Sion Speedway is obvious, it's a time attack time-trial. Maybe instead of Mundo Dodgeball it could be some sort of Whack-a-Mole game with Poppy Q with URF CDs. Target practice: killing as many target dummies as you can with varius marksmen. Idk, I'm just brainstorming. You get the idea. Anything that can have some sort of scoring system to compare/contrast vs other summoners.
