Guide to Blueprint Rooms in The Blue Prince

The incredibly vast estate of Mt. Holly in The Blue Prince has several types of rooms that you can use to traverse through the large estate, which will allow you access to the Anthechamber. One type of room is what the game calls Standard Blueprint Rooms, they’re indicated by a blue border around their edges when they pop up.

Now, these are the common rooms that you’ll most likely be drafting. And most of them have neither beneficial nor detrimental effects when entering them. Basically, you can use them as some sort a safe zone or a nice little transition zone that doesn’t really cost you much of anything as you plan out your route.
