As you traverse through the dynamic Mount Holly Estate, discovering and designing fresh rooms along the way, you’ll come across new listings in the comprehensive Mount Holly Guidebook. The adventurous Blue Prince gamers can utilize these entries to keep tabs on every room within the game and make progress towards unlocking the Explorer’s Trophy, which demands a completed Mt. Holly Directory.

As a gamer diving into the captivating world of Blue Prince, I’ve come to realize that there are 110 rooms in total within this game. However, not every room is accessible right from the start of the adventure. Some intriguing rooms in Blue Prince must be unearthed or included in your deck through the Drafting Studio before you can make use of them.
