Clue Mysteries
Decode witnesses, check reliability and keep clear notes in Clue Mysteries, with a spoiler-free example that separates evidence from inference.
The play at a glance
Record the statement before deciding what it means
Clue Mysteries gives players a casebook and decoding tools rather than simply repeating classic Clue’s hidden-card puzzle. The task is to work out who committed the crime and where that suspect is hiding.
A useful notebook keeps three things separate: what a witness said, whether the statement can be trusted, and what it lets you rule out. A clear record is more useful than an early guess.
Set one case consistently
The manual pairs each case with numbered character-wheel settings. Match each wheel to its named holder and use the selected case’s settings before play. A wheel left on a different case can produce a misleading clue even when the decoding tool is used correctly.
Keep the casebook, assembled character pieces, cards, scene tokens, notebooks and decoding tools together. Check the full component list and illustrated setup before the first game. This is the 50-case Mysteries edition; classic Clue’s weapon, room and suspect-card setup is not a substitute.
Give each tool its own job
- Spyglass
- Decode the six witnesses’ statements.
- Secret mirror
- Read Inspector Brown’s information about witness truthfulness.
- Location key
- Read Mr. Boddy’s hiding-place clue.
- Notebook
- Keep each statement beside its speaker and mark reliability before eliminating suspects.
Within this game, a witness identified as lying gives the opposite of the true clue. Brown’s reliability information therefore changes how the witness statement should be interpreted. This is a fictional rule of the puzzle, not a method for deciding whether a real person is truthful.
An original note-taking example
Imagine a separate, invented puzzle with three suspects: one wears a striped scarf, one a plain scarf and one no scarf. A witness says, “The person wore a scarf.” This example is not taken from any included case.
First record the statement exactly. If the invented puzzle establishes that the witness is reliable, the no-scarf suspect can be excluded. The statement still does not distinguish striped from plain. Writing “striped scarf” would add a detail the witness never supplied.
If reliability is unresolved, put a question mark beside the statement instead of crossing someone out. In a practice discussion, explain what additional information would settle the uncertainty. This exercise is about careful notes; it does not reveal a solution in the box.
Try three short headings on spare paper: Statement, Reliability and Consequence. A consequence should say what follows from the evidence, including what remains possible. Keep this optional practice sheet separate from the game’s official clue sheet.
Check both parts before accusing
The game’s accusation names a culprit and hiding place, and the pawn must be on the relevant scene token. An incorrect accusation removes that player from the game; they must keep the answer private while the others continue. Consult the full movement and accusation rules before making the attempt.
Before committing, review whether each eliminated suspect has a reason beside the name. Then check that the location came from the appropriate clue rather than a guess based on where a pawn happened to travel.
For an optional cooperative teaching session, agree in advance to discuss the notes together instead of racing privately. Explain uncertainty aloud and let each person contribute an observation. This changes the competitive experience and should be presented as a house activity.
Keep the solution pages closed until the rules call for checking. After a case is finished, discuss which clue changed the interpretation without revealing that case to someone who has not played it.
