Blue Prince: The Puzzle Mansion That Took Eight Years and Rewired a Genre
A house that rebuilds itself every night, a 46th room nobody can find, and a designer who funded it all with savings and a Magic: The Gathering website. Inside the making of 2025's best-reviewed puzzle game.
Imagine inheriting a mansion with one condition: find the room that does not exist. The house has 45 rooms, but the will that left it to you insists there is a 46th. And every morning, the floor plan is different.
That is Blue Prince, the debut game of Dogubomb, led by designer Tonda Ros and published by Raw Fury. It launched on 10 April 2025 for PC, PlayStation 5 and Xbox Series X|S, came to macOS on 29 September 2025 and to Nintendo Switch 2 on 3 March 2026. At launch it was the highest-rated game of 2025 by Metacritic average, and it went on to win design prizes at the D.I.C.E. Awards, the Game Developers Choice Awards and BAFTA.
The house that redraws itself
You play a young heir to Mount Holly Estate. The manor is laid out as a 9 by 5 grid of 45 tiles. Only two rooms are fixed: the Entrance Hall, where you start, and the Antechamber at the far end. Every time you open a door, the game offers you three random floor plans and asks you to pick one. That room then appears behind the door.
This is called drafting, and it turns architecture into strategy. Do you take a dead-end bedroom because it has a key you need? A corridor with four exits that keeps your options open? A room that costs gems to place but might hide a clue? You only have 50 steps each day, and every room you enter costs one.
When the day ends, the house quietly resets overnight. Tomorrow's mansion will be built from scratch, by you, one door at a time. What you carry forward is knowledge: codes, notes, patterns and the growing suspicion that everything in the house is connected.
A roguelite for people who keep notebooks
Most roguelites (games where each attempt starts fresh but you slowly unlock advantages) test your reflexes. Blue Prince tests your memory and your notebook. Its puzzles are layered: a painting in one room explains a lock in another, a letter mentions a date that opens a safe, and a fact you learned in your first hour might matter in your fortieth.
That design made it a phenomenon among a particular kind of player, the kind who fills a real paper notebook with arrows, numbers and underlined words. Online communities formed to compare discoveries, carefully hiding spoilers from each other, the way players once traded secrets about Myst or The Witness.
What makes the drafting so clever is that it produces stories. A bad day, where every door offers you a cupboard and you run out of steps in the west wing, still teaches you something about the house. A great day, where the right room appears at the right moment, feels like the mansion is finally cooperating. Because you chose every room yourself, the successes feel earned and the failures feel like your own fault, in the best possible way.
Eight years, one designer and a Magic: The Gathering website
Blue Prince took about eight years. Ros started prototyping around 2016, then quit his commercial job to work on it full time. He paid the bills with private savings and advertising revenue from a Magic: The Gathering website he ran.
That Magic connection shows up in the game itself. Drafting, where players take turns picking cards from a shared pack, is one of the most beloved ways to play Magic, and Ros borrowed it directly for the way rooms are offered. He has also cited the board game Agricola as an influence on that system.
Ros was not entirely alone. The credits list Davide Pellino as artist, the duo Trigg & Gusset as composers and Axel Haavikko as producer. The game was built in Unity.
The puzzle books behind the mansion
Blue Prince wears its reading list proudly. Alongside Manson's Maze, Ros has pointed to:
- The mathematical puzzles of Martin Gardner and the logic riddles of Raymond Smullyan
- Kit Williams's picture book Masquerade, whose illustrations hid a real-world treasure hunt
- Jewels in the Attic, a 1992 board game
- Video games such as Gone Home, The Witness and the clue design of The Legend of Zelda
It is a lineage of puzzles that trust the player. None of these works holds your hand; they give you a strange object and assume you will find it fascinating enough to study. Blue Prince does the same, which is why it can feel like a book you play rather than a game you finish.
By the numbers
- 8 years of development, from early prototypes around 2016
- 45 rooms on the grid, plus the elusive Room 46
- 50 steps a day
- 92 on Metacritic for PC, 90 for Xbox Series X|S, 85 for PS5
- 95% of critics recommend it on OpenCritic
- 5 platforms so far: PC, macOS, PlayStation 5, Xbox Series X|S and Nintendo Switch 2
A trophy cabinet full of design awards
Critics loved Blue Prince, but the award juries made a more specific point: this was a triumph of design. At the 29th D.I.C.E. Awards in February 2026 it won Outstanding Achievement for an Independent Game and Outstanding Achievement in Game Design. At the Game Developers Choice Awards it won the Innovation Award. At BAFTA it won Game Design, and it was nominated for Best Game, Debut Game and Narrative.
It also took Best Indie Game at the Golden Joystick Awards 2025, Game of the Year and Innovation at The Indie Game Awards, and the Off Broadway Award for best indie game at the New York Game Awards. At The Game Awards 2025 it was nominated for Best Independent Game and Best Debut Indie Game, in a year when Clair Obscur: Expedition 33 swept almost everything (read that story).
Why it matters
WGC's take: Blue Prince proves that a single strong idea, executed with patience, can still stand out in a market flooded with games. It did not chase trends. It took a 40-year-old tradition of puzzle books, combined it with a card-game drafting system and a roguelite structure, and produced something genuinely new.
It is also a reminder of what indie time looks like. Eight years is a long time to fund yourself. The game exists because one designer was willing to bet his savings, and because a publisher like Raw Fury was willing to back something that is hard to explain in a trailer.
What to play next
Blue Prince is available on Steam for Windows and macOS, on PlayStation 5, Xbox Series X|S and Nintendo Switch 2. Bring a notebook. You will need it.
If Blue Prince left you craving more notebook games, try Inscryption, the card game that hides an entire mystery inside itself (read our feature). For another kind of mystery, Urban Myth Dissolution Center turns internet rumours into detective cases (here). And if you want drafting with numbers instead of rooms, Balatro remains the reigning champion (here).
