How to Win in Blue Prince

Blue Prince challenges you with one of gaming's most intricate puzzle mansions, where victory means reaching the mysterious Room 46. This roguelike puzzler hides layers of secrets behind its deceptively simple room-drafting mechanics, and many players never discover just how deep this blue rabbit hole goes. You'll need strategic planning, resource management, and puzzle-solving skills to navigate the 9x5 mansion grid and unlock its final chamber.

Core Mechanics You Must Master

Every run in Blue Prince starts fresh with an empty mansion grid. When you open doors, you'll choose what room appears on the other side from randomly drawn options. This drafting system forms the heart of your strategy - you're not just exploring, you're actively building your path to victory.

Your primary resources are steps, keys, gems, and coins. Running out of steps triggers a new day, resetting most progress but maintaining certain permanent upgrades. Keys unlock crucial doors, gems purchase special items, and coins buy essential tools from vendors.

Permanent Upgrades to Secure First

Before attempting your Room 46 run, secure these game-changing permanent upgrades:

Orchard Code Upgrade

Head to the orchard behind your campsite and enter code 1128. This grants you an extra 20 steps at the start of each day - absolutely crucial for longer runs.

Gemstone Cavern Breaker Box

Solve the electrical puzzle in the gemstone cavern to earn 2 gems every new day. This steady income helps purchase keys and special items throughout your runs.

The Three-Door Antechamber Challenge

The antechamber sits permanently at the mansion's center-north position, sealed behind three doors: east, south, and west. You must unlock at least one door by pulling its corresponding lever hidden elsewhere in the mansion.

East Door: Great Hall Strategy

The Great Hall contains six locked doors arranged in two rows of three. Behind one random door lies the east lever. You have several approaches:

• Brute Force Method: Collect 6+ keys and systematically check each door
• Master Key Strategy: Purchase the master key from the showroom to open any standard lock
• Foyer Combo: Draft the Foyer room, which permanently unlocks all hallway doors for that run

South Door: Greenhouse Lever Repair

The Greenhouse spawns randomly on the mansion's western or eastern edges. Inside, you'll find a lever missing its handle. Your mission: locate the broken lever item and repair it.

Broken Lever Locations:

• Security room, aquarium, workshop
• Attic, laboratory, observatory
• Dark room, spare room, store room, wait room
• Use metal detectors or shovels to increase discovery chances

West Door: Secret Garden Wind Vane Puzzle

Acquire the Secret Garden Key through various methods:

• Random spawns in attic, lost and found, mechanarium, music room
• Billiard room prizes
• Locked trunks and dig spots
• Locksmith purchase (8 gold for random special key)

Use the key on locked doors in columns 1 or 5 to reveal the Secret Garden. Inside, adjust the three wind vanes using nearby valves until all arrows point toward the rear wall statue. This reveals the hidden west lever.

Basement Access: Two Critical Pathways

After unlocking any antechamber door, grab the basement key from the raised pedestal inside. You'll need this key to access the underground areas through one of two permanent routes.

Route 1: Foundation Elevator

The Foundation appears randomly during runs as one of the few permanent rooms. When drafting it, place it strategically toward the mansion's southern or northern end.

To activate the Foundation elevator:

1. Build a room connecting to the Foundation's fourth wall (the one without a door)
2. Look for the crank mechanism instead of a standard door
3. Interact with the crank to permanently power the elevator
4. Use your basement key on the fancy door below

Route 2: Fountain Drainage System

This method requires the Pool and Pump Room combination. Draft the Pool first, which adds the Pump Room to your available options.

Fountain Drainage Steps:

1. Enter the Pump Room and locate the control panel
2. Press the button under the fountain plaque to activate the system
3. Use the middle lever (Pump 2) to drain fountain water into the tanks
4. Switch valves to alternate between tanks as they fill
5. Continue until all blue indicators above the fountain label turn off

The Underground Puzzle Sequence

Once you've opened either basement entrance, you'll face a complex multi-stage puzzle that requires careful planning and often multiple runs to complete.

Storage Room Cart Puzzle

In the Foundation basement, navigate the storage room filled with boxes and hand trucks:

1. Clear the entrance by pulling the first hand truck aside
2. Position carts strategically - move two hand trucks into the back gaps
3. Adjust pallet heights - keep moving pallets in lowered position initially
4. Create walkable path - use planks and raised pallets to cross box tops
5. Activate green button - this permanently opens the passage to the reservoir

From the fountain entrance, locate the mine cart on its track. Pull the cart backward to block the fountain path but open access from the Foundation route. This positioning is crucial for the final gear puzzle.

Rotating Gear Chamber Solution

The gear chamber connects both basement entrances and holds the key to reaching Room 46:

1. Enter from Foundation side after solving the storage puzzle
2. Rotate the gear platform using the control button
3. Align the platform with the exit behind the mine cart position
4. Cross the gap and proceed to the inner sanctum
5. Pull the north lever to unlock the final antechamber door

The Final Sprint to Room 46

Here's where step management becomes critical. The north antechamber door unlock is temporary, meaning you must complete a full run from the basement to Room 46 without calling it a day.

Step Conservation Strategies

Victory Path

1. Complete the basement sequence and pull the north lever
2. Maximize your steps using the conservation strategies above
3. Navigate back to the antechamber through your previously unlocked door
4. Enter through the north door you just unlocked
5. Proceed directly to Room 46 for your first victory

Post-Victory Content and Continued Exploration

Reaching Room 46 marks just the beginning of Blue Prince's deeper mysteries. Your first victory unlocks new rooms for subsequent runs, and each additional completion reveals even more hidden content.

The game's true complexity emerges after your initial victory, with post-credit puzzles that challenge even the most dedicated players. While we've guided you to your first win, the mansion's deepest secrets await your own detective work.

Victory unlocks include:

• New room types in the drafting pool
• Additional puzzle mechanics
• Hidden areas and secret codes
• Extended storyline content

Whether you're planning to master every mystery Mount Holly contains or simply want to experience this unique puzzler's core content, these strategies will transform you from a confused newcomer into a confident mansion navigator. Take your time, manage your resources wisely, and remember - in Blue Prince, patience and planning always triumph over rushing toward the goal.
