Start with a clear intent: this guide walks you from core setup to chapter-by-chapter play. It draws on Do Games Limited’s Android release and on classic chapter layouts from Mystery Case Files: The Harbinger.
Expect familiar patterns: HOPs (hidden object puzzles) supply essential items, maps unlock fast travel, and code panels most often ask for five-digit or three-digit entries — these beats repeat across parts and pages in the genre.
We show how to read scenes for answers and evidence, how to capture exact strings in notes, and how to use in-game tools (for example, the “Eliminate Anomaly” mechanic) to confirm your next move without guessing.
Practical focus: learn to spot quick wins, cross-check a short video when stuck, and keep brief searchable notes on key files and clue phrasing. The checklist below gives a repeatable method you can use on mobile or PC so each chapter becomes a predictable sequence of small solutions.
Key Takeaways

Start Here: How to Navigate Hidden Objects, Codes, and Puzzles with Confidence
Before you tap in, set up your device and pick a focused goal for this page. A short pre-game checklist keeps play calm and productive when a new part opens.
Quick Setup Checklist (do this first):
- Enable Do Not Disturb on mobile or lower background apps on PC.
- Raise brightness or tweak gamma and set cursor/zoom sensitivity for comfortable spotting.
- Open a notes app or camera so you can copy exact strings and photograph tricky screens.
Know the lingo. HOPs are your primary item engines: clear high-contrast items first to generate tools that speed progress across parts. Use the map to fast-travel between active markers instead of running around to save time.
Treat tokens and emblems as keys. Symbols like illusion, lunar, or glove commonly match nearby pedestals or panels — scan frames, carved inlays, and corner details first to find scene matches before trying guesses at a code panel.
- Sweep each scene left-to-right, top-to-bottom, then zoom hotspots for layered reveals.
- Capture answers and evidence verbatim in a note or photo so the exact wording maps to future code entries or book passages.
- Before entering digits, double-check nearby notes, torn pages, and signage; many three-digit or five-digit locks pull their solution from an in-scene clue.
Example micro-step: if you open bag and find a Strange Purse, check the archive desk for a matching diary excerpt — combine those two items to reveal a key or password rather than trying random codes.
Practical device tips: keep a camera or screenshot tool handy for hard-to-copy puzzles, and label multi-step containers in your notes (e.g., “Chest — needs key, code, lantern”). Always trigger map hints after major pickups — new markers usually point to solvable locks or fresh HOP locations you can hit in one loop.
Play with intent. Label rooms and multi-step containers in your notes, use hints sparingly to confirm a path, and resist using a skip until you’ve tried combining obvious items (for example, take ladder only when a ladder socket is visible, or open door after inserting the discovered key). This approach turns small wins into steady chapter progress.
mystery files hidden objects walkthrough: Step-by-Step Progress for Each Chapter
Follow a clear chapter rhythm to turn small pickups into steady progress across each part. Start with a fast sweep, trigger the map after major finds, and use HOPs as item engines that often reappear when a new page opens.
General tips
Use the map to fast travel after pickups and stitch a 2–3 stop route so you hit fresh markers efficiently. HOPs tend to cluster by location—scan known hubs first. Keep your notes labeled with exact phrasing so code entries and book references are faster.
Chapter 1 — The Fated
Objective rhythm: sweep → clear HOPs → combine early items → open gate. Follow device prompts to Eliminate Anomaly, then use the archive key and alarm keycard to open early gates. Combine Strange Purse + diary excerpt to reveal a password or a missing key item.
- Micro-walkthrough (minimum steps): Find Strange Purse → Check archive desk for Diary Excerpt → Combine → Use found key on archive door.
- Code examples (illustrative): some multi-digit locks use five-digit entries — sample try: 75462; compact panels sometimes expect three digits — sample try: 137. Only use examples when the lock type and clues match.
- Common pickups: dog tag, travel logo, medical supplies — chain these for a solution that opens a treatment cabinet or reveals a hidden note.
Chapter 2 — Nigel’s House
Place illusion tokens to reveal riddle parts and inspect the candelabrum: lighting it will surface hidden picks in dark rooms and often unlock a sequence on an adjacent panel. Check under rugs, inside drawers and the open bag in the foyer for a torn page or a ring that triggers a side quest.
- Micro-walkthrough: Find Illusion Token → Place on pedestal → Collect Riddle Part → Use to solve small chest → open cabinet or reveal a safe combination.
- Look for keys in unlikely places (wallet, glove compartments, under picture frames). If a window is obstructed, try walking twice across the yard to trigger a neighbor’s clue or a dropped tool.
Chapter 3 — Shop Street
Assemble the Tourist Center map to unlock vendors and trading options. Build the lantern (Gas + Stained Glass), fit cogwheels into the shop display, then pull levers to expose music notes puzzles and clockwork doors. Vendors may trade a fishing rod, a car jack, or a car part that you’ll need later.
- Micro-walkthrough: Collect map pieces → Fast-travel to Tourist Center → Trade for Cogwheel → Build Lantern → Use Lantern on dark alley to reveal a knife or tape needed for another puzzle.
- If a door needs a physical tool, try take bolt, take metal, or bolt cutters depending on the lock style; some sequences require pushing a button or pulling a lever three times or walk twice across a threshold to trigger a change.
Chapter 4 — The Forest & Boss highlights
Craft healing sets and candles from twine and wax. Use the censer with aromatic leaves, apply the awakening potion to the idol, and then follow the Ancient Book statue sequences to trigger the boss mechanics. Many boss gates combine a pattern solution (wheel tiles or ring alignments) with a timed button press or coded input.
- Inventory synergy: Small chains (glove → ring → key) often teach the interaction cadence; combine items early to avoid backtracking across parts.
- Puzzle types: Expect sequence locks, wheel tiles, pattern solutions, and anomaly-style mini-games that test pattern recognition and timing.
- If stuck: check your diary or torn pages for phrase strings, then watch a short video clip for only the blocked step — prefer a targeted clip rather than a full solution.
Navigation notes & quick solutions: label your notes with room names and exact strings (code digits, book phrases). For any door that remains closed, re-check nearby signs, boards and clipped photos — many doors use local visual clues as their code source. If a safe needs a safe combination, test logical patterns from nearby signage and try three-times increments (e.g., walk twice between checks) before using a heavy tool like bolt cutters or a car jack.
Pro Tactics for Any Mystery Case Files-style game walkthrough
Simple routines will help you collect, decode, and lock in evidence without backtracking. Use a concise plan each time a new part loads so small finds become lasting progress.
Evidence workflow: Capture exact strings and icons with a camera or note, then tag clues with the room name. When you use the map to return, the tags let you fast-travel to the correct marker instead of re-scouting entire areas.
File discipline: When a diary or folder has multiple tabs, copy keyword combinations verbatim — phrases from books or torn pages often map directly to later code panels or sign clues.
Cracking codes and symbols — a 4-step checklist
- Scan nearby media: check clipboards, photos, and recent diary pages for exact digits or phrases.
- Group symbols: for icon locks, cluster by theme (moon phases, musical notes, figurines) and order logically — waxing to waning or low to high pitch.
- Test systematically: try the most likely numeric options first (local sign numbers, recent note sequences) and log failures so you don’t repeat the same attempts three times needlessly.
- Save targeted video help: if stuck, watch a short clip for the single code or HOP location blocking progress — stop after confirming the step to preserve the puzzle challenge.
HOP mastery & puzzle triage
Clear large, high-contrast items in HOPs to reduce clutter quickly; leave the last two items for the hint to keep momentum. Prioritize mechanical puzzles that unlock new rooms (pull lever, fit cogwheel, turn wheel) because those yield items and new panels.
- Start mechanical gates: tackle levers and cogwheels first so new areas and doors open.
- Run a focused HOP sweep: in newly opened rooms, do a short sweep to collect items (knife, tape, board pieces) that unlock deeper puzzles.
- Queue crafting: prepare combos (take rope + take metal → make hook) before moving on so you don’t backtrack across parts for simple assembly steps.
“Use the map after any big solve; route a 2–3 stop chain to hit new markers in one loop.”
Annotated example — symbol grouping
Scenario: a lock shows three icons — crescent, full moon, new moon. Grouping by lunar phase (waxing → waning) gives the solution order. Annotate the note as: “Moon lock = crescent → full → new” so you can paste the exact string into your notes and test without guessing. This approach works for music notes (low → high) and figurine sizes (small → medium → large).
Quick tactics and common solutions
- Camera & notes: use screenshots for complex boards and photographic clues; label each image with the room and the suspected solution string.
- Buttons & timing: some puzzles need you to push button or pull lever a set number of times (push button thrice or pull lever three times); try “three times” patterns when the environment hints at repetition.
- Physical tools: if a door or cabinet resists, check if you need bolt cutters, a car jack, or to take ladder — many locked doors yield after a tool is applied in the right place.
- Walk routing: sometimes you must walk twice between triggers to refresh NPCs or move an object; use this when markers don’t update after an action.
Final tip: make this page your quick reference: print a one-page cheat sheet of the 4-step code checklist, common tool uses (bolt cutters, car jack, fishing rod), and the most frequent solution patterns (sequence locks, wheel tiles, symbol grouping). Cross-link chapter-specific solutions from here to speed lookup during play.
Conclusion
This final page ties the tactics together so you can close chapters with calm and clarity and return to the next part with a clear plan.
Keep notes tight. Copy exact phrasing, symbol sets, and digits so every code panel and sequence lock becomes a quick confirm instead of a guess. Use short labels and room tags for fast lookup (e.g., “Archive Desk — code,” “Foyer — torn page”).
Work in loops. Fast travel to new markers and stitch a 2–3 stop route so you hit fresh objectives efficiently. Pair crafting steps before you move — small acts like lighting a lantern or assembling a ladder often open the next chain immediately and avoid needless backtracking.
Limit video checks. Watch only the single step that blocks you (a code entry or one HOP location), then return to the flow to preserve the puzzle satisfaction. Use videos as a targeted tool, not a substitute for observation.
Quick reference — common code types
- Three-digit panels: check nearby torn pages, signage, and short diary entries first.
- Five-digit panels: look for longer number strings in ledgers, boards, or pictures; try logical permutations before brute force.
- Sequence locks (symbols): group icons by theme (book phrases, moon phases, musical pitch) and test in the natural order suggested by the scene.
Final action: bookmark this walkthrough or print the one-page cheat sheet (4-step code checklist, common tools, and room-label template). If you spot an error or a missing part, report it with a timestamped clip or a short note so we can update the solution quickly.
