Board Game Arena

I started a table, three others joined. I don't want to have one of the players in this game.

How can I expel this player? I only see the options "Go to game" and "Quit game" - both are not what I want.

Is there a possibility to expel a player in this situation without quitting the whole game (and without getting penalized)?

If that's what you see, it means the game has started, even if no one has made a move yet. You cannot expel someone (unless they run out of time), but you could propose to abandon the game after you explain the situation.
