You’re standing in the foyer of Mt. Hebron. The air is thick with dust and the smell of old paper. You have 45 days to find Room 46. Sounds simple, right? It isn't. Blue Prince isn't your typical mystery game where you just point and click until a cutscene triggers. It’s a brutal, cerebral mix of architectural strategy and rogue-like resource management. If you go in treating it like a standard walking simulator, the house will eat you alive.
Honestly, the hardest part about learning how to play Blue Prince is unlearning how you play other games. You aren't just exploring a floor plan; you are literally drafting it in real-time. Every door you open is a gamble. Every room you place is a permanent decision—at least for that day.
The Blueprint Mechanics are the Heart of the Game
In most games, the map is a static thing. In Blue Prince, you create the map. When you approach a closed door, the game presents you with three random room cards. This is where the strategy begins. You aren't just looking for "cool" rooms. You’re looking for functional connections.
If you pick a hallway, you’re playing it safe. Hallways give you more doors, more chances, more breathing room. But if you pick a specialized room—like a library or a study—you might find a clue or a tool, but you might also hit a dead end. Dead ends are run-killers.
Managing Your Stamina
Every single room you "draft" or enter costs you energy. It’s represented by that little gauge that depletes far faster than you’d like. Once you run out of steps, your day is over. You wake up back at the start.
The trick is efficiency.
Don't just wander. If you see a room card that doesn't advance you toward the center of the manor or help you solve a current puzzle, don't take it just because it’s there. Sometimes the best move is to double back through rooms you’ve already placed, even if it feels like wasting time. It’s better to spend two steps backtracking than five steps placing useless rooms that lead to a literal brick wall.
Solving the Puzzles Without Losing Your Mind
The puzzles in Mt. Hebron are tactile. You’ll be looking at schematics, listening to audio recordings, and fiddling with mechanical devices that look like they were pulled out of a 1920s patent office.
The game doesn't hold your hand.

Take the "Grandfather Clock" sequence or the various "Lock" puzzles. They require genuine observation. You need to look at the environment. Is there a painting with a specific number of birds? Is there a ledger nearby that mentions a specific date? Everything is a clue.
- The Golden Rule: If a room looks unique, it has a purpose.
- The Silver Rule: Collect every single "Gem" you find. These are your meta-currency.
Gems allow you to buy permanent upgrades between runs. This is the "rogue-lite" side of the game. If you're struggling to reach the deeper levels of the house, stop trying to solve the main mystery for a few runs. Just focus on collecting gems and dying intentionally. It sounds counterintuitive, but boosting your starting stamina or unlocking the ability to "re-roll" room cards is the only way you'll ever see Room 46.
Understanding the Narrative Layers
Sam Barlow and the team at Half Moon Studios designed this to be a slow burn. You play as Simon, who has inherited this massive, shifting estate. But the story isn't just told through dialogue. It’s told through the architecture itself.
You’ll find notes from previous explorers. You’ll find records of the "Blue Prince" project. Pay attention to the names. Names like Hale or Kaufman appear in different contexts. If you find a letter in a kitchen, it might provide the code for a safe you found three runs ago in a completely different wing of the house.
Mt. Hebron is a character. It's fickle. It changes its layout every morning because the "drafting" process resets. However, the puzzles you solve often stay solved, or the knowledge you gain carries over in your own head.
Advanced Tactics: The Mid-Game Pivot
About ten hours in, you’ll hit a wall. You’ll feel like you’ve seen every room card. This is when you need to start looking at "Room Synergy."
Some rooms buff others. If you place a "Power Station" next to a room that requires electricity, you save yourself the headache of finding a portable battery. If you manage to chain together "Garden" tiles, you might find a shortcut that bypasses half a floor.

Pro Tip: Always keep a "Restoration" card in your back pocket if the game offers it. Being able to replenish a small amount of stamina mid-run is the difference between reaching a new checkpoint and collapsing in a hallway like a failure.
What Most Players Get Wrong
The biggest mistake is trying to "beat" the house in one go. You can't. The game is designed for you to fail.
When people ask how to play Blue Prince, they usually want a walkthrough. But a walkthrough is useless because the map is different for everyone. Instead, focus on the "logic" of the manor.
- Don't hoard your gems. Spend them as soon as you get back to the hub.
- Read the room descriptions. Some rooms have hidden properties, like allowing you to see what’s behind the next three doors.
- Use the "Void" sparingly. You can discard room cards, but it costs you. Only do it if all three options are dead ends.
The game is a conversation between you and the architect. He's trying to trap you in a loop of nostalgia and confusion. Your job is to be the most boring, methodical surveyor in history. Trace your steps. Label your mental map.

Actionable Steps for Your Next Run
To actually make progress tonight, stop playing like an explorer and start playing like a contractor.
- Prioritize Stamina Upgrades: Your first five gem purchases should strictly be related to movement and energy. Nothing else matters if you can't reach the second floor.
- Document Everything: Keep a physical notepad next to your keyboard. Write down safe codes, weird symbols, and room names. The game won't always track these for you in a way that’s easy to parse mid-puzzle.
- The "North Star" Strategy: Always try to draft rooms that move you toward the top-right of your grid. The game tends to bury progress-critical rooms further away from the entrance.
- Ignore the Flavor Text (Initially): If you're low on energy, don't stop to read the lore. Get to the next door. You can read the lore on a "farming run" where you aren't trying to make progress.
Mastering the house is about patience. You will draft the same "Library" forty times. You will fail to find a key. You will run out of breath inches away from a new discovery. But eventually, the layout will click, the gems will pile up, and Room 46 will finally open its doors.
