Puzzles and decoded journals

01 · Do this

Follow the route in order.

1. 01

   Wireless Room — Reach the room in Akeley Hospital and speak to all three brains in jars. Collect the three testimonies and the Note About Wireless Room.

2. 02

   Wireless Room — Start with Pence's clue: the primary frequency is the bad-luck number on Fridays, so the first dial is 13.

3. 03

   Wireless Room — Use Dunwich's clue to round the primary number to the nearest ten and halve it: the second dial is 05.

4. 04

   Wireless Room — Use Ambrose's clue to double the sum of the first two numbers: 2 × (13 + 5) = 36 for the third dial.

5. 05

   Wireless Room — Set 13, press the central button; set 05, press it again; set 36, press it once more. Green feedback confirms each accepted number.

6. 06

   Salt Storage wooden lock — Press the Roman-numeral sequence I → IV → IX → XVI. The three connected notes are the intended clue route for this numbered wooden lock, and it awards the Pyre's Squid Barrel grenade-launcher upgrade.

7. 07

   Fish Market / Ezekiel buoy — Use the Bolt Cutters to enter the Fishing Shop's side room, inspect the connected evidence, and set the four symbols left to right to Lighthouse → Ropes → Starfish → Octopus (some notes call the first symbol a lantern). Validate to open the buoy/cabinet and collect Doyle's Hot Streak for the SMG.

8. 08

   Abandoned Office ward / Old Freddie — If the ward seals Ma Fishface's Shop, leave the office and inspect the Old Freddie mural near the Cold Storage door. Shoot the second figure from the right, the one not playing an instrument, take Freddie's Urn, then return and use the urn on the ward. The Leyden Jars power separate Starfish gates; they do not dispel this ward.

9. 09

   Leyden Jar chain — In the Fish Market, take the first jar from the Construction Site, use it on the blocking Starfish, and keep retrieving and reusing it as you open the Guard Post, East Pier, Warehouse and West Wing gates. After the two Starfish gates around the Jewelry Workshop open, recover both jars before continuing through the Antikythera route; do not leave a jar permanently placed.

10. 10

    Leyden Jar chain — After the Antikythera route and the 6294 memory-safe sequence, return to the present and use the Heart of Ice on the Cold Storage statue to get the depleted jar. Recharge it at the Construction Site by pulling the switches at the red lights; the recharged jar joins the two recovered jars.

11. 11

    Leyden Jar chain — Carry all three jars to the Broken Hold and place them in the three Starfish to open the wreck route. This is the three-jar progression; the jars are not the item that dispels Ma Fishface's ward.

12. 12

    Fish Market frozen statue — Place the Heart of Stone and select the arms in this order: Woman on knees → Octopus → Monster on Pedestal → Hourglass → Leyden Jar. A wrong order damages or resets the puzzle; the correct order gives the blue Heart of Ice.

13. 13

    Cold Storage statue — Carry the Heart of Ice to the statue, defeat the Deep One, then place the Heart of Ice in that statue to receive the final Leyden Jar. This is a separate statue route, not another Salt Storage or Ezekiel code.

14. 14

    Devil's Reef Hotel / Staff Key and Lorelei Tokens — After the hotel route drops you into the lower area, pick up the Staff Key from the table and return through the safe-room route. Go back up to the second floor, open the staff-room door at the end of the corridor, and take the three Lorelei Tokens and the note. Use one token on each Lorelei Chest around the hotel to recover the three keys for the basement Lorelei Lock.

15. 15

    Lorelei Lock — Use the Staff Key on Room 303 upstairs for the first chest, use a token on the second-floor Room 203 chest and shoot the four cursed objects (three in the room and one in the bathroom), then use the last token on the bar-area chest near the Staff Key. Take all three keys through the Safe Room to the basement lock before the ventilation route.

16. 16

    Devil's Reef gas puzzle / ventilation — Reach the basement Generator Room after the Lorelei Lock. From the machine's untouched/default state, press Button 1 twice, Button 2 four times, Button 3 twice, pull the lever, then press Button 1 once. The four gauges should enter their green marks and clear the poisonous gas; pick up the Minuteman beside the machine before leaving.

17. 17

    Hospital Prism — Carry the Prism to three stations in order: blue Treatment Room, yellow Priest's Room off the Chapel after obtaining Father Nathaniel's face, then pink Manipulations Room after the Vertebral Key, Lowe's face, and its boss fight. Each station needs its own three colored Investigation symbols; do not reuse another station's symbols.

18. 18

    Hospital Prism / Treatment Room — After taking Anti-Rust Acid and collecting the three blue symbols, use the acid to open the central staircase and enter the Treatment Room. Place the Partially Charged Prism on the blue station, align the found symbols with the blue marker at the top, and validate.

19. 19

    Hospital Prism / blue — Find the three blue symbols at the Anatomical Theater/Treatment Room desk note, upstairs from the Morgue near the poster's shimmering light, and the Therapeutic Garden's glowing bear trap. At the Treatment Room station, align those symbols with the blue marker and validate.

20. 20

    Hospital Prism / yellow — Find the three yellow symbols through the Caduceus Key door at the glowing body, in Medical Records after the Mirror Door at the glowing spot, and at the Chapel's glowing spot. At the Priest's Room station, align those symbols with the bottom-left yellow marker and validate; the exact shape labels are kept out of this page where guide text and screenshots disagree.

21. 21

    Hospital Prism / pink — Find the three pink symbols through the balcony window near the Isolation Wards, in the first-floor Pharmacy by the glowing book (Caduceus Key), and beyond the Vertebrae Lock at the glowing point on the body pile. At the Manipulations Room station, align them with the bottom-right pink marker and validate; when all three eyes glow, return the Prism to the terminal by Faye's body.

22. 22

    Hospital / Vertebral Key — After the Yellow Prism station, take the Head Surgeon's Face Mask from the brain-filled room behind the Chapel altar. Use it to enter the Head Surgeon's Office upstairs; pick up the Vertebral Key from the desk, move the cabinet to reach the Nurses Station, then use the key on the locked door by the stairs north of Reception to reach the final pink-symbol body.

23. 23

    Church graveyard / Printing House — When the crane route is blocked because the crane is missing its gear, take the Graveyard Key and Soggy Note at the Saloon/Silver Eel; return to the Church's locked graveyard gate, enter the Printing House, and take the Steel Gear. Then return to the crane to restore the route and move the whale. This is the Graveyard Key route, not the separate Church Key.

02 · Confirm

What success looks like.

• The machine accepts 13, 05, and 36 in that order.
• The three brains' puzzle completes and the room awards Dream Essence.
• The route remains optional; skipping it does not block the Hospital's main Prism progression.
• Salt Storage accepts I, IV, IX, XVI and yields Pyre's Squid Barrel.
• The Salt Storage numbered wooden lock accepts I, IV, IX, XVI.
• The Fish Market/Ezekiel buoy accepts Lighthouse, Ropes, Starfish, Octopus and yields Doyle's Hot Streak.
• The Abandoned Office ward opens after Freddie's Urn is taken from the non-playing figure in the Old Freddie mural.
• The Fish Market, Cold Storage and Construction Site route produces three usable Leyden Jars for the Broken Hold's three Starfish.
• The frozen statue accepts Woman on knees, Octopus, Monster on Pedestal, Hourglass, Leyden Jar and produces the Heart of Ice.
• The Cold Storage statue route ends with the final Leyden Jar after the Deep One encounter.
• The Staff Key opens the second-floor end-of-corridor staff room, where the three Lorelei Tokens are waiting.
• The three Lorelei Chest keys open the basement Lorelei Lock before the ventilation route.
• The Devil's Reef ventilation machine accepts 1×2, 2×4, 3×2, lever, 1×1 from its untouched/default state and clears the gas route.
• The Treatment Room blue Prism station accepts its three found symbols after the Anti-Rust Acid route.
• The Prism's blue, yellow and pink stations all register, then the terminal by Faye's body accepts the fully charged Prism.
• The Head Surgeon's Office desk supplies the Vertebral Key, which opens the lower Hospital door to the final pink symbol.
• The Church's locked graveyard gate opens with the Graveyard Key, leading to the Printing House and its Steel Gear route before the crane/whale progression.

03 · Boundaries

Before you retry.

• This page answers the named Wireless Room, Prism, Salt Storage, Fish Market/Ezekiel buoy, frozen-statue, Church graveyard, and ventilation routes, not every journal, code, safe, or later chapter puzzle.
• The route assumes the current full-release Hospital layout and the three brain testimonies are present; do not apply 13-05-36 to another lock.
• Prism stations use found symbols rather than a universal numeric code. The guide text and screenshots for the yellow station are not fully consistent on shape labels, so this page does not hard-code a disputed transcription; use the three yellow Investigation symbols and the bottom-left yellow marker.
• The ventilation sequence is only verified from the machine's untouched/default state. If buttons have already been pressed, do not replay it blindly; restore the current puzzle state or reload the last save.
• The Graveyard Key route is separate from the Church Key/trident route; this page identifies the Printing House path but does not replace the full printing-plate walkthrough.
• The Hotel Staff Key/Lorelei Token and Hospital Head Surgeon/Vertebral Key routes are cross-checked by GameSpew and the independent 100% Guides collectible walkthrough; this page does not claim every collectible or every encounter outcome.
• Hotfix 1.0.1 fixed Prism removal during validation and a third lamp in A Sight for Sore Eyes; Hotfix 1.0.2 lists no change to these routes. If a Prism station still fails to validate on an older build, update before retrying.
• Connect the clues in Investigations if you want the upgrade point; the number sequence alone is the shortcut answer.

04 · Undo

If it does not trigger.

• If a number is rejected, stop and check that you are on the correct dial and have entered the leading zero in 05.
• Leave and reload the last save if the machine fails to advance; no files or external tools are required.
