Nobles

At the end of your turn, if your card bonuses meet at least what a noble tile shows, that noble visits you and you take the tile: it's worth 3 prestige. Visits are automatic — you can't refuse one — and don't count as your action. You can receive only one noble per turn, and you can't get a noble by spending tokens, only through bonuses.

With The Cities: The Noble tiles are not used with The Cities.
