Blue Prince Beginner's Guide

Updated May 11, 2026 · 12 min read · For new players

Blue Prince looks like a quiet manor exploration game and then quietly reveals it is a deeply strategic roguelike. This guide gets you from "lost in the foyer" to "running confident drafts" in about an hour of play.

How a Day Works

Each day in Mt. Holly follows the same loop: enter a room, pick from a hand of three rooms to place behind the next door, walk into it, repeat. You start in the Entrance Hall with 50 Steps. Every doorway you cross costs 1 Step. When Steps hit zero, the day ends.

The goal isn't to visit every room — it's to build the right shape of mansion for what you want that day. Some days you're hunting for the Boiler Room because you have a code; some days you're stretching Steps because tomorrow's draft pool is better.

The mansion resets every day. Rooms placed yesterday are gone. But upgrades you unlock (permanent keys, lore items, codes you write down) carry over. The progression is in the player's head and notebook, not in the save file.

The Draft System

When you approach a closed door, you get a hand of 3 rooms drawn from the room deck. Pick one — it becomes the next room. The other two go to the discard pile. Some rooms re-shuffle the discard back in; most don't.

Reading a Room Card

Every room card shows four things:

Rarity color — gray (common), blue (uncommon), purple (rare), gold (legendary).
Cost — many cards have a placement cost in Gems, Coins, or Steps.
Door count — how many doors the room has. More doors means more options later, but each door must be drafted for.
Effect — what happens on entry. Always read this before you place, not after.

The Three Draft Rules

Always read all three cards first. The card on the right isn't always the worst option — the game shuffles randomly.
Skipping is free. If you don't like any of the three, walking back out of the doorway costs no Steps and re-draws nothing (your hand is the same when you return — but a turn passed).
Path before reward. A room that pays out 5 Gems but is a dead end is worse than a hallway that opens three new doors.

The Four Resources

Resource	Used For	How to Earn
Steps	Crossing doorways	Pantry, Kitchen, certain consumables
Gems	Drafting rare rooms, paying placement costs	Storeroom, Mine, gem chests
Keys	Opening steel doors and locked chests	Locksmith, hidden in drawers, Vault rewards
Coins	Slot machine, certain placement fees, vending devices	Sofas, jars, the Wishing Well

Step Economy

Steps are your day timer. Every doorway = 1 Step. A naive player burns 50 Steps in 50 doors. A good player extends a run to 80–110 doorways by routing through Step-generating rooms.

The Pantry trick: Pantry gives +5 Steps the first time you enter. If you place it at a Y-junction so you naturally cross it twice in a route, you get +5 the first time only — but the path through it is "free" in terms of opportunity cost.

Gem Economy

Gems are how you get into the good rooms. Most legendary rooms cost 4–6 Gems to draft. Casual players reach day 10 with 8–12 Gems total. Strong players hit day 10 with 30+.

The compounding source is the Mine. Place it once, run a Storeroom or Strongroom next to it, and you double your daily Gem income. Don't sleep on the Mine just because it has only one door.

Best Opening Moves

Your first 5 rooms set up the day. These are the openings that consistently work:

Hallway first. Hallways are free to place and give you a 2-door junction. If a Hallway is in your opening hand, take it 90% of the time.
Then Pantry or Kitchen. Step income is your priority. Without it, you'll run dry by room 12.
Now a value room. Storeroom, Library, or Workshop — anything that generates a resource or unlocks utility.
Save Bedroom for last. Placing the Bedroom guarantees you can end the day. But you don't want to end the day in the first half of a run.
Lock down the East Wing intentionally. Don't draft into the East Wing path until you have a plan — it's a long corridor with several gated rooms.

Room Tier List

Ranked by value across a typical run, accounting for placement cost.

Tier	Rooms	Why
S	Pantry, Mine, Vault, Locksmith	Direct resource pumps. Always take.
A	Library, Kitchen, Workshop, Conservatory, Hallway	Generate value or open paths. High flex.
B	Storeroom, Drawing Room, Den, Music Room	Situationally strong. Take if synergies exist.
C	Closet, Billiard Room, Parlor	Puzzle rooms — only valuable if you can solve them this run.
D	Bathroom, Foyer	Filler. Skip unless desperate.

Trap room: The Trophy Room looks legendary because of the gold border, but its effect only triggers once per game and is gated behind another puzzle. Skip it on early runs.

Keep a Real Notebook

This isn't a metaphor. Open Notes or grab paper. Blue Prince expects you to remember things across runs that the game itself doesn't track:

The 4-digit code on the Vault door.
Which star pattern was visible on day 1.
Which color the Billiard Room balls were arranged in.
Names mentioned in letters — they unlock dialogue branches later.

Players who clear Room 46 in under 20 days almost universally took notes. Players who skip note-taking average 60+ days.

Where to Go Next

Once you're comfortable running a day without panicking about Steps:

Read the puzzle solutions — knowing the answers in advance lets you build runs around solving them.
Then attempt the Room 46 walkthrough. You'll need 3–4 specific items and a route plan.
