Board Game Arena

Hello !
I wonder what the gurus are for and how is it possible to become Guru for a specific game ?

Thanks

Simple. You are a guru if you are amongst the most active players in arena for said game.
Guru can suggest changes for the setup for the next arena season and they can vote for suggestion they want to support

Thanks for the answer. How many Gurus are there for a given game ? How active do you need to be ?
And what are the other roles for the gurus ?
