Learn how the four cases in Sherlock Holmes: Four Investigations are structured, how to choose your detective, and how the replayable solution system works.
Your detective, your deductions
Sherlock Holmes: Four Investigations puts you in the shoes of either Dr. John Watson or Sherlock Holmes himself. That choice is the first step in how you play: each case asks you to apply intuition and deductive reasoning, and the character you pick frames how you approach the evidence.
The game is built around four separate cases. You do not need to solve them in a fixed order—each case stands on its own—but the skills you sharpen in one will carry into the next.
What you need to start
- Sherlock Holmes: Four Investigations: Choose to play as Dr. John Watson or as Sherlock himself. Your choice of detective is the only setup decision the game asks for before you begin a case.

Sherlock Holmes: Four Investigations - Sherlock Holmes: Four Investigations: It will take every bit of intuition and deductive reasoning you can muster to solve the cases in this one! This tells you the core activity: reading clues and reasoning them out, not rolling dice or managing resources.
How a case unfolds
The exact sequence of a case is not detailed in the supplied information, but the overall flow follows the graphic novel adventure format: you read, make choices, and follow leads.
- Pick your detective: Decide whether you will play as Watson or Holmes. This is your only pre-case setup choice.
- Read and follow leads: Work through the case by reading the narrative and pursuing the clues that seem most promising.
- Reason it out: Use intuition and deductive reasoning to connect what you have learned and reach a solution.
- Check your solution: The game's unique system lets you verify whether you have solved the case correctly.
- Replay without spoilers: If you have not yet solved a case, you can play it again without learning the solution.
The replay system, explained
The most distinctive feature of Four Investigations is how it handles solutions. According to the product description, the unique system allows you to play over and over without learning the solutions of each case until you have successfully solved them. That means a failed attempt does not spoil the answer—you can revisit the same case with fresh eyes.
The description also asks: 'But will you be able to ignore your curiosity and play through it again without looking at the solutions?' That is the real test. The game trusts you to resist peeking, and the reward is a case you can genuinely solve rather than merely read.
The replay promise
- Sherlock Holmes: Four Investigations: The unique system allows you to play over and over without learning the solutions of each case until you have successfully solved them. This is what makes the four cases replayable: you can retry a case without the answer being revealed.
Tips for sharper deductions
These suggestions are based on the skills the game explicitly calls for—intuition and deductive reasoning—not on any hidden rules.
- Take notes as you go: Jotting down names, times, and contradictions gives your intuition something concrete to work with.
- Trust your first instinct, then test it: The game asks for intuition, but deduction means checking whether your hunch holds up against the clues.
- Resist the solutions: The replay system only works if you avoid looking at the answers before you have solved the case. Treat that as part of the challenge.
- Try the other detective: After you solve a case, you can replay it as Watson or Holmes to see how the experience changes.
