Permanent Unlock Codes

These codes unlock permanent upgrades that benefit every future run. Prioritize these first!

🍎 Apple Orchard Gate
Location: Outside, left of your tent
1128

This is the first code you should unlock. The Apple Orchard gives you a permanent +20 steps every day.

How to find it: Leave the mansion through the front door. Head up the path to the left past your tent. The gate is just behind the campsite.

Room Safe Codes

These safes appear in specific rooms. Each contains a Red Letter and random valuables (gems, keys, or coins). Safe contents reset every day!

💄 Boudoir Safe
Room Type: Bedroom (corner room with 2 doors)
2512

The safe is behind the mirror/room divider. Look for a photo on the nightstand showing a Christmas scene.

The Clue: The photo shows Christmas Day → December 25th → 2512 (DD/MM) or 1225 (MM/DD). Try both formats if one doesn't work.
🏛️ Office Safe
Room Type: Office
0303

The safe is hidden! Open the right desk drawer to find a dial. Turn it to reveal the safe on the opposite wall.

The Clue: A note mentions "March" + count the busts of Count Isaac Gates in the room (there are 3). March = 03, busts = 03 → 0303
♟️ Study Safe
Room Type: Study
1208

The safe is to the left of the entrance door. Look at the chess board on the table – there's a single Black King piece.

The Clue: The Black King sits on square D8. Convert to a date: D = December (4th month?), 8 = day → Actually D8 = December 8 → 1208 (DD/MM) or 0812 (MM/DD)
📐 Drafting Studio Safe
Room Type: Drafting Studio
1108

There's a diorama with a miniature safe inside. Use a Magnifying Glass to zoom in and interact with it.

The Clue: Check the calendar in the room – it shows November with only two dates visible. The solution is your second day in the game: November 8 → 1108 (DD/MM) or 0811 (MM/DD)
🎨 Drawing Room Safe
Room Type: Drawing Room
0415

The safe is hidden behind a wall panel. Pull the left candlestick above the fireplace to reveal it.

The Clue: This is part of a meta-puzzle involving paintings across the mansion. Count paintings showing people with "short steps" (legs close together): 4 women + 15 men. Since the painting hiding the safe shows a woman, put women first → 0415

Special Codes

🚪 Red Door (Underground)
Location: Underground, near Rotating Gear
MAY8

This padlock uses letters and numbers. After powering the red control box in the Boiler Room, the Red Door can be opened.

The Clue: The last slot only allows numbers. The first three slots are letters. MAY is the only 3-letter month that fits, and 8 is the only number option → MAY8. Note: As of v1.05.1, Red Doors stay open permanently once unlocked!
⏰ Shelter Time-Lock Safe
Location: Shelter (Outer Room)
DYNAMIC

This safe doesn't use a fixed code. Instead, you program a future time via the terminal, then wait for it to unlock.

How to Open:
  1. Calculate the current date: Day 1 = November 7. Add your day count. (e.g., Day 22 = November 28)
  2. Check the current time at the clock in the mansion entrance
  3. At the terminal, set a time at least 1 hour ahead (round up to next hour)
  4. Wait in real-time (~5 minutes per game hour) or continue playing
  5. Return when the time has passed to open the safe

Passwords

💻 Terminal Password
Used in: Security, Shelter, Office, Laboratory
SWANSONG

All terminals in the game share the same password. This unlocks access to security cameras, experiments, and more.

How to Find: Draft the Commission Shop. Look at the bulletin board – there's a staff notice with a crossed-out password. Use a Magnifying Glass to read it clearly: SWANSONG

Tips for Safe Hunting

✅ Pro Tips
  • Carry a Magnifying Glass – Some clues require zooming in
  • Try both date formats – MM/DD and DD/MM both work for most safes
  • Safes reset daily – Collect gems from the same safe every run!
  • Red Letters are unique – Each safe gives a specific letter only once
  • Check hidden switches – Some safes need to be revealed first (candlesticks, desk drawers)

The Paintings Meta-Puzzle

Throughout the manor, there are 44 pairs of paintings. Each pair contains a hidden clue related to safe codes. The paintings often show people with "long steps" or "short steps" (distance between their legs), which corresponds to digits in various combinations.

This is a deeper puzzle that connects all the safes together. If you want the full experience, examine every painting you find and look for patterns!
