Mary's Mystery: Hidden Object - Follow the Clues to Alice
Mary's Mystery: Hidden Object is a narrative-driven detective game set in 1920s Britain. Alice is missing, and her sister Mary will not stop until she uncovers the truth. Search hand-painted locations for hidden clues, use collected tools on objects in each scene, and solve sharp mini-puzzles as the mystery unfolds in your browser.
Search for Clues and Uncover Alice's Story
Every scene holds another piece of the case. Check the item list at the bottom of the screen, inspect furniture and shadows, and select each hidden object you recognize. Key finds enter your tool storage, where they can be dragged onto the right part of the scene. Codes, circuits, and broken mechanisms stand between Mary and the next chapter of Alice's story.
Hand-Painted 1920s Mystery Scenes
Explore detailed British interiors filled with period furniture, deep shadows, and objects hidden in plain sight. Each location advances Mary's search for her missing sister.



Clue-Focused Hidden Object Gameplay
Use the list at the bottom of the screen to guide your search. Look behind shadows, inspect period furniture, and select every item concealed in the artwork.
Tools That Change the Scene
Important finds move into your tool storage instead of disappearing. Drag a tool onto the matching object, such as placing a vinyl record on a gramophone, to trigger the next clue.
Detective Mini-Puzzles
Hidden object scenes are joined by chapter puzzles. Crack codes, connect circuits, and assemble broken mechanisms to open new paths through the investigation.
Hints for Difficult Finds
Use the magnifying glass to inspect suspicious details. When an object remains out of sight, spend a Hint to reveal it, but keep this limited help for the toughest clues.

How to Play Mary's Mystery: Hidden Object
Review the Object List
Check the bottom of the screen to see what Mary must find. Every listed item is hidden somewhere in the current hand-painted location.
Scan the Scene
Examine furniture, shadows, and decorative details for recognizable shapes. Select each hidden object you spot and use a Hint only when the search stalls.
Use the Tools You Find
When a key item enters tool storage, drag it onto the matching object in the same scene. The correct interaction reveals clues and moves the investigation forward.
Solve Each Chapter Puzzle
Decode symbols, repair circuits, and rebuild mechanisms that block Mary's path. Completing each puzzle reveals more about Alice's disappearance.
Mary's Mystery: Hidden Object blends careful search-and-find play with a continuing detective story. Its hand-painted period scenes, usable inventory items, and varied mini-puzzles make every discovery feel connected to Mary's search for Alice rather than like an isolated object list.
