How do you promote a game that is a new genre?

I know the popular advice would probably be "don't attempt to invent a new genre"

But if you did invent a new genre of video game, how would you go about promoting it? Popular ways of promoting games are by going to areas where there are players who enjoy the genre of your game, or other popular games in your genre, or popular content creators that play your genre.

If there are no other games that fit your genre, how do you promote the game? Are there any places online where people enjoy innovative games?

How would you explain a new genre to players or get people interested?

Just wanted to spark some discussion! :)
