The Mermaid Mask — Every Puzzle Solution

Serpent Cabinet

The cabinet shows four number windows — 3, 4, 7, 8 — and a tray of tiles. Place each tile in the window that matches its number of corners:

• Triangle (3 corners) → window 3
• Square (4 corners) → window 4
• Heptagon (7 corners) → window 7
• Octagon (8 corners) → window 8

The drawer ejects a key fragment.

Cauldron Deduction

In the Illusion Theater you reconstruct the death. The correct conclusion is:

"Magnus unlocked the cauldron and was killed by what was inside."

Select that line. The killer was concealed inside the cauldron, not lurking in the room.

Wooden Box

Six cards and four lenses. The rule:

• The girl card must see the center slot.
• The left outside doll uses the small lens.
• The right outside doll uses the big lens.

Arrange: small lens left, big lens right, girl aligned to center. The box opens.

Control Room Wiring

See the dedicated guide, but the short version:

Energizing the board unlocks the Captain's Log.

Piggy Bank

Each coin face shows features (dots, stripes, stars). Toggle coins so the sum of visible features equals the red target number. Start from the highest-value coin and work down.

Phone Anagram

A ruined phone displays scattered letters. Rearrange them on the keypad to spell the captain's nickname fragment — MORT. The dial tone reveals the next locker code.

Typewriter

The platen is offset. Rotate the typewriter 45° so the printed glyphs align with the guide sheet pinned above it. The message reads a cabin number.

Dream Bottle

Place the seven etched tokens in this exact order:

1. Arrow
2. Bird
3. Skull
4. Moon
5. Hand
6. Eye
7. Sun

The sequence mirrors the mural in Dr. Zephr's quarters.

Cargo Pinboard

Pin the crew photographs, then stretch red thread between each photo and the cargo manifest entry that matches their handwriting. Three correct links pop the safe.

Engine Room Compass

Set the compass to the heading spelled by the three dials you collected (e.g. N 47°). The rudder unlocks the hold.

Treasure Chest

A "pirate pairing tower": stack the paired pirate tokens so each matching pair sits on the same shelf. Order does not matter, pairs do.

Skeleton Rack

Reassemble the display bones in anatomical order — skull, ribs, pelvis, limbs. The rack yields the final key.
