Hidden Memories Mobile: Nine Hidden Shadow Locations

Mobile edition · Updated Sep 23, 2026

Visual reference for Hidden Shadows

Quick answer

The mobile walkthrough documents nine base-story shadows: two in the Unknown Place, two in the Bar, one in the Garden, two in the Laboratory and two in the Mansion. These are separate from the nine lost-soul dolls. Steam advertises ten hidden shadows; the additional location is not covered here.

Before you begin

Before you begin

  • Progress the main story to unlock each memory; the second Unknown Place shadow requires reaching its later chair room.

Follow the clues

  1. 01

    Check your shadow collection

    Open the collectibles menu and look at the shadow silhouettes. Compare the missing entries against the nine locations below as each memory becomes accessible.

    You’ll know it worked: You can track which shadows still need collecting.

  2. 02

    Find both Unknown Place shadows

    Check the right-corner flower pot in the pizza-box room. Later, when the chair room opens, lift the red cushion from its chair.

    You’ll know it worked: Both Unknown Place shadows are registered.

  3. 03

    Find both Bar shadows

    Open the red bench or chest beside the magician. In the clown’s stage room, pull aside the right red curtain.

    You’ll know it worked: Both Bar shadows are registered.

  4. 04

    Find the Garden shadow

    At the large frog, inspect the tree just to its right.

    You’ll know it worked: The Garden shadow is registered.

  5. 05

    Find both Laboratory shadows

    At the microscope, select 100× magnification. In the room with the brown cat, open the window and inspect the red bush outside.

    You’ll know it worked: Both Laboratory shadows are registered.

  6. 06

    Find both Mansion shadows

    Lift the floor plank beside the wall metal grille. At the graveyard-facing window, tap the nearest gravestone.

    You’ll know it worked: Both Mansion shadows are registered.

If you’re still stuck

Are shadows the same as Lost Soul dolls?

No. Shadows are a separate set of hidden silhouettes. The dolls start Lost Soul object-search minigames; use the separate doll checklist for those.

Why is the microscope shadow missing?

Use the microscope and change its view to 100×; merely opening the microscope view is not the location step.

Where is the second Unknown Place shadow?

Under the red cushion on a chair in a later opened room of the Unknown Place. It is not in the starting pizza-box room.

Does this list require premium content?

The nine locations here are the base-story shadows reported by the public walkthroughs. The premium chapter is separate.
