About the game
Welcome to Mt. Holly, where every dawn unveils a new mystery. Navigate through shifting corridors and ever-changing chambers in this genre-defying strategy puzzle adventure. But will your unpredictable path lead you to the rumored Room 46?
Welcome to Mt. Holly, the mysterious manor with shifting rooms. In Blue Prince, you embark on a genre-defying experience, filled with a unique mix of mystery, strategy, and puzzles that weave together to create an unpredictable journey. Will your explorative steps lead you to the rumored Room 46?
DRAFTING YOUR JOURNEY
Upon reaching a closed door in Mt. Holly, you decide what room appears behind it and each decision shapes your path as you navigate through the manor. Every door can reveal new and exciting chambers that contain their own unique challenges and secrets. But be careful how you draft, for each day the manor’s floor plan resets and the rooms you saw today may not be the same rooms you see tomorrow.
EVERY STEP COUNTS
Your progress each day is shaped by the rooms you select to draft and the tools you find within them. Items in the game can be used in a number of creative ways to fuel your exploration deeper into the house, allowing you to adopt unique strategies to combat the challenges that each day brings. Yet, tread wisely – the house resets each dawn, erasing all but the permanent upgrades to your estate blueprint. That is, if you were clever enough to find one!
A HISTORY IN THE MAKING
As the heir of Mt. Holly, you have been tasked to explore its shifting halls in search of Room 46. Yet as your journey takes you further into the mansion’s depths, you start to discover that there is more lurking under the surface than a missing room. Investigate a past woven with the threads of blackmail, political intrigue, and the mysterious disappearance of a local children’s book author. The deeper you venture, the more you realize that the past is closer than it appears.

Story
AI-assisted summaryYou play as Simon P. Jones, who has inherited Mt. Holly Estate from his late great-uncle, Herbert S. Sinclair. The will sets one condition: find a hidden forty-sixth room inside the mansion before the inheritance is truly yours. The house does not stay still. Each morning its layout is rebuilt, and you choose which chamber appears beyond every closed door by drafting from a small set of floor plans. Keys, gems, coins, and tools found along the way help you push farther, but steps are limited and almost everything you carry is lost when night falls. As you search for Room 46, notes and clues also point toward older mysteries tied to the manor, including the vanishing of a local writer of children's books.
Full story (spoilers)
Simon P. Jones arrives at Mt. Holly and camps outside. The estate lies in Fenn Aries, one of many city-states on Mora, a world like Earth except that airships are ordinary transport and drafting can summon or dissolve rooms. An uncensored history book explains that peaceful Orinda Aries fell when nobles from Fenn and Oris, opposed to King Desilets III's generosity toward commoners, staged the Fennsurrection. After the War of Ruin, unpopular Desilets IV went into exile. General Teskin imposed authoritarian rule as Fenn Aries and changed the sigil from black to red. Those events frame the disappearance of children's writer Marion Marigold, Simon's mother Mary Jones. After the government censored The Red Prince—his childhood book about loving red, whose ending of seeing blue sky was read as political—she joined Children of Black Water. She stole the ruby crown in a major heist, then fled, hoping Simon would discover the clues. Sinclair was an accomplice and was later blackmailed by gardener Denny Revane with letters stolen from Room 46. Getting to the antechamber of the 46th room lets Simon reach the estate's inner sanctum, which holds traces of miners who happened on ancient Castle Orindia, once the capitol of Orinda Aries. Room 46 holds the crown, its rubies swapped for sapphires, called the Crown of the Blueprints. Using that crown and other items, Simon drafts the throne room, takes the old throne, and becomes the Blue Prince. Afterward he can uncover the secret will of manor designer Baroness Auravei.
