In Case Solved: The London Files, every accusation must rest on a chain of evidence. Separate confirmed details from suspects’ statements before forming a theory; one early hunch can otherwise steer the entire investigation in the wrong direction.
Separate solid clues from suspicion
- Each case is a self-contained logic puzzle with a provable solution.
- Contradictory statements, alibis and environmental clues must be compared.
- Hidden codes can unlock optional secret cases.
- Steam presents the game as a single-player experience with Steam Achievements and Steam Cloud.
Minimol Games builds its cases around contradictory statements, alibis and environmental clues. The official Steam page describes deduction puzzles with a provable solution. Treat every new clue as a way to rule out a possibility, rather than immediate proof that your first suspect is guilty.
Read the evidence in sequence
Read every available statement once without accusing anyone. Then sort the information into people, locations, times, objects and relationships. A specific place or time is more useful than a vague impression of the suspect who seems most suspicious.
- Read every statement and inspect every accessible part of the scene.
- Set aside facts that are clearly stated or shown.
- Identify two details that cannot both be true.
- Test one consequence of that contradiction.
- Return to the evidence before confirming the accusation.
When two theories remain possible, favour the one that produces a clear exclusion. If a detail rules out neither a person, location nor timeline, it may be background context rather than the key to the case.


Use contradictions to eliminate suspects
A suspect can seem convincing while still being wrong. When a statement feels doubtful, ask what it prevents from being true. If someone claims to have been elsewhere at a specific time, compare that version with every clue linked to that moment and location.
| Situation | Useful instinct | Mistake to avoid |
|---|---|---|
| Two alibis seem possible | Compare the time, place and detail they have in common. | Choosing the least likeable character. |
| A clue seems isolated | Connect it to a statement before dismissing it. | Treating it as mere scenery. |
| You are stuck | Return to the last confirmed fact and list the exclusions. | Changing theories with every reread. |
| The answer seems obvious | Check that every remaining clue still matches. | Confirming before eliminating the alternatives. |

Search the scene for confirming details
Official descriptions indicate that progress comes from gathering information on suspects and searching for environmental clues. Explore the scene with a specific question in mind: can an object confirm a time, a location or the nature of an event?
Keep physical evidence separate from testimony. A suspect can lie. A visible clue still needs to be interpreted, but it provides a stronger starting point for the next comparison. To follow more puzzle and investigation games, browse jeu.video features and the news selection.

Get unstuck without guessing
Turn a difficult case into a closed question. Ask yourself who cannot be in a location, which statement contradicts an object, or which option remains if a claim is true. A good deduction eliminates one possibility. If it requires several new assumptions, return to the last solid fact.
Difficulty does not mean that information is missing. These puzzles rely on logic rather than random validation. Make sure an assumption has not quietly become a fact before attempting another answer.
Case Solved: The London Files is presented as a single-player game. Platform availability may vary by store region: the official Nintendo listing and the official PlayStation listing are the safest sources to check before buying. Recent releases are also gathered in jeu.video’s latest news.

Leave hidden codes until the end
Steam presents hidden codes as a way to unlock optional secret cases. They reward players who want to extend the mysteries, but they are not a shortcut through the current investigation. Finish the main case first, then look for unusual details in the game world, on the Steam page and in related official documents.
This order preserves the appeal of the puzzle: solve the chain of evidence yourself before treating secret codes as an extra.

Frequently asked questions
What should you do before accusing a suspect?
Check that the accusation fits every confirmed clue and that the remaining alternatives have been ruled out.
How do you choose between two alibis that both seem possible?
Compare their time, location and any object linked to the event. Look for the detail that makes one version impossible.
Should you inspect the scene or reread statements first?
Inspect the scene when you do not yet have a solid fact. Environmental clues can provide the context needed to test a statement.

No. Steam describes them as a way to unlock optional secret cases.
Where can you check available platforms and game mode?
Check the official Steam page, the Nintendo listing or the PlayStation listing, depending on your region. Official information presents the game as a single-player investigation and puzzle experience.
