Blue Prince has more than 100 rooms to sort through, and several of those rooms can be upgraded as well. This means that everyone's playthrough of Blue Prince will be a little bit different, depending on which upgrades they choose.

One of the many rooms that can be upgraded is the Guest Bedroom. This room has three different possible upgrades from its upgrade disk, and you might be wondering which is the best to pick.

The Guest Bedroom in Blue Prince

The Guest Bedroom is a purple bedroom that is also a dead end. The basic version of this room gives you ten additional Blue Prince steps when you enter it for the first time. It can also have an item on the side table directly across from the door, including things like the Compass, a key, or a gem. There is a single note inside the Guest Bedroom as well; it is a note from a friend of your grand uncle's who mentioned that they like the new dartboard puzzle put in the Pool Room.

All Upgrades for the Guest Bedroom in Blue Prince

In order to upgrade this room, you will need to find one of the many Blue Prince Upgrade Disks located in the rooms around the manor. When placed in a computer, these disks give you a random selection from a small group of rooms that can be upgraded, and each gives you three options for upgrades. These are the Guess, Geist, and Quest Bedroom.

The Quest Bedroom

If you have drafted the Quest Bedroom, and then you enter the Antechamber in Blue Prince, you will gain an Allowance token that raises your daily allowance by two. Since there are loads of other ways to get Allowance tokens, this feels like the weakest of the possible upgrades for the Guest Bedroom.

The Geist Bedroom

The Geist Bedroom is a haunted version of the original. You get two Ivory Dice every time you draft this room, and then you get additional Ivory Dice if you have also drafted the Tomb outside the house.

The Guess Bedroom

The most interesting of the upgrades is the Guess Bedroom. Inside, you will find items that mimic items you would find in a different bedroom, and you need to guess which room the Guess Bedroom is copying. Keep in mind that the only rooms that are in your draft pool are possibilities for the Guess Bedroom, so any rooms that aren't already drafted and are possible in your specific drafting pool. Here is a breakdown of how to know which room you have gotten:
