Blue Prince drops you into Mount Holly, a manor whose floor plan redraws itself every morning. You play the heir, and the estate only passes to you if you reach Room 46, a room that should not fit inside a house that has 45. Each day is a fresh draft, and the knowledge you carry out of a failed run matters far more than the rooms you drew.
This walkthrough takes you from your first session to endgame content. Each phase has specific goals, priorities, and milestones. New to the game? Start with our beginner's guide first.
Quick Progression Summary
| Phase | Area | Focus | Build | Duration |
|---|---|---|---|---|
| 1. Start | Entrance Hall | Room drafting basics | Gem economist | 1-2 hours |
| 2. Early | Antechamber | Daily floor plan reset mastery | Gem economist | 3-5 hours |
| 3. Mid | Parlor | Step economy + gear | Blueprint planner or Gem economist | 5-10 hours |
| 4. Late | Boiler Room | Build optimization | Blueprint planner | 5-10 hours |
| 5. Endgame | Greenhouse | Min-max | Blueprint planner or Dead end avoider | Ongoing |
See our maps guide for detailed area breakdowns.
Phase 1: Getting Started (Entrance Hall)
The fixed starting point every single day. Its three exits set the shape of the whole run, so the first draft is the decision with the widest consequences.
Level/Difficulty: Day 1 onward Key Rewards: Run direction, first room choice
What to Do in Entrance Hall
- Learn Room drafting. Every closed door offers three room options and you pick one. Spend your first session getting comfortable with this.
- Pick Gem economist as your starting build. See our builds guide for why.
- Treat door count as the primary drafting stat for the first half of a day. A mediocre room with three exits keeps a run alive far longer than a strong room that dead ends, because every sealed direction permanently shrinks the map you can still reach.
- Acquire your first equipment upgrade: Lockpick or whatever's available.
- Clear all main content before moving on.
Phase 1 Checklist
- Understand Room drafting fundamentals
- Gem economist selected and functional
- Entrance Hall main content cleared
- Ready for Antechamber
Phase 2: Early Game (Antechamber)
The gateway to Room 46 at the top of the map. Reaching it needs both a connected path and the resources still in hand once you arrive.
Level/Difficulty: Mid to late run Key Rewards: Room 46 access, main objective progress
What to Do in Antechamber
- Work on Daily floor plan reset. Sleeping or running out of steps ends the day and wipes the layout. This system becomes critical from here on.
- Farm for Lockpick if you haven't already. It's the key upgrade for this phase.
- The Parlor's three box puzzle is solvable by pure logic from the statements on the boxes, and it resets daily with fresh values. Learning to read it in under a minute turns it into a repeatable source of gems and keys rather than a gamble.
- Complete all objectives before pushing to Parlor.
- Consider whether Blueprint planner might suit your playstyle better than Gem economist.
Phase 2 Checklist
- Daily floor plan reset integrated into gameplay
- Lockpick acquired
- Antechamber fully cleared
- Ready for Parlor
Phase 3: Mid Game (Parlor)
Home to the three box logic puzzle, one of the earliest reliable resource sources in the game once you understand how the statements resolve.
Level/Difficulty: Early run Key Rewards: Gems, coins, keys
What to Do in Parlor
- Master Step economy. Each move between rooms costs a step from a finite daily pool. This unlocks a new layer of gameplay.
- Start working toward Sledgehammer. It's the best equipment and becomes accessible around now.
- Codes, names and numbers you find in notes stay true across days because they describe the estate, not the layout. Keep a physical notebook; the game deliberately does not track them for you.
- This area is the main skill check. If you can clear it, you're ready for late game.
- Start investing in Keys and gems for the tactical depth you'll need going forward.
Phase 3 Checklist
- Step economy mastered
- Sledgehammer acquired or in progress
- Parlor fully cleared
- Ready for Boiler Room
Phase 4: Late Game (Boiler Room)
A utility room tied to the manor's wider systems rather than to immediate loot. Its value shows up in what it switches on elsewhere.
Level/Difficulty: Mid run Key Rewards: System activation, estate progress
What to Do in Boiler Room
- Finalize your build. You should be running Blueprint planner or Gem economist with optimized gear.
- Sledgehammer should be your primary. If you don't have it yet, prioritize getting it.
- Aim your drafts up the map rather than sideways. Room 46 sits behind the Antechamber at the top, and horizontal sprawl burns steps without shortening the distance to the objective.
- Estate blueprint upgrades optimization starts here. Small improvements compound into massive advantages.
- Farm this area for the resources needed to push into Greenhouse.
Phase 4 Checklist
- Build fully optimized
- Sledgehammer upgraded to max
- Boiler Room fully cleared
- Ready for Greenhouse
Phase 5: Endgame (Greenhouse)
An outdoor room that pays out in consumables and dig sites, useful when you are long on steps and short on supplies.
Level/Difficulty: Any Key Rewards: Consumables, dig spots
What to Do in Greenhouse
- Greenhouse tests everything. Come prepared with your best build and gear.
- Rooms that grant steps pay for themselves immediately. Draft them the moment they appear rather than saving the slot for something with better loot, because loot is worthless once the day ends.
- The endgame loop: run Greenhouse, optimize gear, push harder content.
- Experiment with Dead end avoider for a fresh take once you've mastered the standard builds.
- This is where Estate blueprint upgrades mastery separates good players from great ones. See our tips guide for advanced strategies.
Phase 5 Checklist
- Endgame content on farm
- Best-in-slot gear acquired
- Greenhouse fully cleared
- Ready for challenge content
Common Progression Mistakes
- Drafting for loot instead of for exits, then dead ending at half the map
- Spending the last key on a side room and stranding the Antechamber path
- Not writing down codes, then rediscovering the same information for a third time
- Sprawling sideways across the lower rows and running out of steps below the midpoint
- Skipping the Parlor because the puzzle looks slow, giving up a reliable resource room
Key Tips for Smooth Progression
- Treat door count as the primary drafting stat for the first half of a day. A mediocre room with three exits keeps a run alive far longer than a strong room that dead ends, because every sealed direction permanently shrinks the map you can still reach.
- The Parlor's three box puzzle is solvable by pure logic from the statements on the boxes, and it resets daily with fresh values. Learning to read it in under a minute turns it into a repeatable source of gems and keys rather than a gamble.
- Codes, names and numbers you find in notes stay true across days because they describe the estate, not the layout. Keep a physical notebook; the game deliberately does not track them for you.
- Aim your drafts up the map rather than sideways. Room 46 sits behind the Antechamber at the top, and horizontal sprawl burns steps without shortening the distance to the objective.
