Clue (Cluedo) Rules: How to Play the Classic Mystery Board Game

Someone has been murdered at Tudor Mansion, and only careful detective work will unmask the culprit. Clue (called Cluedo outside North America) is one of the greatest deduction games ever made — a perfect blend of logic, bluffing, and process of elimination that has kept families glued to the table since 1949. But despite its long history, there are several key rules that get misplayed in homes around the world, leading to arguments, confusion, and games that end prematurely or run far too long.

Quick Answer: Clue is a 2–6 player mystery game where you move around a mansion, make Suggestions to gather clues, and use deductive reasoning to determine which suspect, weapon, and room are hidden in the Case File envelope. When you’re certain, you make an Accusation. Guess correctly and you win; guess wrong and you’re eliminated.

What’s in the Box?

Standard Clue sets include:

• 1 gameboard (Tudor Mansion floor plan with 9 rooms)
• 6 suspect tokens (Scarlet, Mustard, White, Green, Peacock, Plum — names vary by edition)
• 6 weapon tokens (Candlestick, Knife, Lead Pipe, Revolver, Rope, Wrench)
• 21 Clue cards (6 suspects, 6 weapons, 9 rooms)
• 1 Case File confidential envelope
• A detective notepad (one sheet per player)
• 2 dice
• A deck of blank/move cards (in some editions)

Note: Hasbro has released numerous special editions with different characters, weapons, and room names — but the core mechanics remain identical. This guide focuses on the classic rules that apply to all editions.

Setup: Preparing the Mystery

Step 1: Prepare the Case File

This is the most important setup step. Before anyone looks:

1. Separate the 21 Clue cards into three piles: suspects (6 cards), weapons (6 cards), rooms (9 cards)
2. Shuffle each pile face-down separately
3. Take one card from each pile without looking at it, place them in the Case File envelope, and seal it. This is the solution — the murderer, weapon, and location.
4. Shuffle all remaining cards together into one deck

Step 2: Deal the Remaining Cards

Deal all remaining cards face-down, one at a time, to all players. Some players may receive more cards than others — this is normal and by design. Players keep their cards secret throughout the game.

Step 3: Place Weapons and Tokens

Place one weapon token in each of the nine rooms (one weapon per room at start). Place all suspect tokens at their designated starting squares on the board.

Step 4: Determine First Player and Setup Notepads

Each player takes a detective notepad. The notepad lists all suspects, weapons, and rooms — you’ll use it to track what you’ve eliminated during play. The youngest player (or randomly chosen player) goes first; play proceeds clockwise.

The Suspects

Classic Clue features six suspects, each with a distinctive colour:

Miss Scarlet always moves first, regardless of who is playing as her.

The Nine Rooms

The mansion contains these rooms: Kitchen, Ballroom, Conservatory, Billiard Room, Library, Study, Hall, Lounge, and Dining Room. The Study and Kitchen are connected by a secret passage, as are the Conservatory and Lounge — allowing instant travel between them on your turn.

How a Turn Works

On your turn, you do the following in order:

1. Roll the Dice and Move

Roll both dice and move your token that many squares in any direction (you cannot move diagonally or pass through walls). Your goal each turn is to enter a room.

You do not have to move the full number shown on the dice — you can move fewer spaces if you prefer. You can change direction during movement but cannot backtrack over the same square in a single move.

2. Enter a Room (or Use a Secret Passage)

To make a Suggestion, you must be inside a room. If your dice roll lets you enter a room, you can move in and make a Suggestion this turn. If you’re already in a room at the start of your turn, you may use a secret passage (if available) instead of rolling.

Important: You are not required to leave a room. You can stay in the same room across multiple turns, but you can only make one Suggestion per turn, and you can only suggest the room you are currently in.

3. Make a Suggestion

Once in a room, you make a Suggestion — your hypothesis about the murder. A Suggestion has three parts: a suspect, a weapon, and the room you are currently in.

Example: “I suggest it was Miss Scarlet, in the Kitchen, with the Candlestick.”

When you make a Suggestion:

• Move the suggested suspect token to your current room (even if it’s already there — this is correct)
• Move the suggested weapon token to your current room
• The player to your left now checks their hand

4. Disproving a Suggestion

Starting with the player to your left, each player in turn checks whether they hold any of the three cards mentioned in your Suggestion (the suspect, weapon, or room card).

• If a player holds one or more of those cards, they must show you exactly one of those cards, privately (only you can see it). That player’s turn ends here.
• If a player holds none of the cards, they say “I cannot disprove” and the next player clockwise is asked.
• If no player can disprove your Suggestion, it may mean those cards are in the Case File — or that all three cards are held by a single player who didn’t show them.

You record on your notepad what you’ve learned. The player who showed you the card also notes that you now know about it.

The Accusation: When to Strike

A Suggestion is how you gather information. An Accusation is your final answer — and you can only make one per game.

When Can You Make an Accusation?

You can make an Accusation on your turn, at any time — you do not need to be in any specific room. This is one of the most commonly misunderstood rules. (Suggestions require you to be in the relevant room; Accusations do not.)

How to Make an Accusation

1. Announce: “I am making an Accusation: I believe it was [Suspect] in the [Room] with the [Weapon].”
2. Pick up the Case File envelope and secretly look at all three cards inside.
3. If all three match your Accusation: you win! Reveal the contents to everyone.
4. If any card does not match: you have lost. Return the cards to the envelope without revealing the contents. You are eliminated from making further Accusations, but you stay in the game as a “ghost” — you continue to disprove other players’ Suggestions but cannot win.

Be certain before you accuse. In my experience, the biggest mistake newer players make is accusing too early on a hunch rather than through solid logical elimination.

Secret Passages

Four rooms have secret passages connecting them diagonally across the board:

• Study ↔ Kitchen
• Lounge ↔ Conservatory

If you start your turn in any of these four rooms, you can use the secret passage as your move — sliding instantly to the connected room. You can then make a Suggestion about the new room. You do not roll the dice when using a secret passage.

Getting Pulled Into a Room by Another Player’s Suggestion

When another player makes a Suggestion and names you as the suspect, your token is moved to their room — even if that wasn’t where you planned to go. On your next turn, you can either leave that room normally by rolling the dice, or make a Suggestion about the room you’re now in.

This mechanic is often used strategically — suggesting a far-away suspect can teleport that player’s token to give you information while also repositioning them inconveniently.

Keeping Notes: Your Detective Pad

The detective notepad is your most powerful tool. Here’s how to use it effectively:

Mark What You Hold

First, go through your own cards and immediately mark them as “safe” (confirmed not in the envelope). These cannot be part of the solution.

Track What Others Show You

When a player shows you a card to disprove your Suggestion, mark it next to that player’s column — you know they hold it, and it’s not in the envelope.

Track What Others Cannot Disprove

If multiple players pass on disproving a Suggestion, note which cards those players do NOT hold. This negative information narrows down the possibilities significantly.

The Cross-Referencing Technique

When a player disproves another player’s Suggestion (not yours), you don’t see the card — but you know it was one of the three suggested cards. If you later eliminate two of those three from your knowledge (because you see them in your hand or someone shows you), you can deduce which card that player showed.

Common Rules Mistakes to Avoid

• Confusing Suggestions and Accusations. A Suggestion must name the room you’re currently in. An Accusation can name any room and be made from anywhere on the board.
• Forgetting to move suggested tokens. When you make a Suggestion, you must physically move both the suspect and weapon tokens into your room. This is mandatory, not optional.
• Showing more than one card when disproving. If you can disprove a Suggestion with multiple cards, you choose which one to show — you never show more than one.
• Skipping players when disproving. Every player must be asked in clockwise order. You cannot skip to the “most likely” player to disprove.
• Assuming “no disproof” means it’s in the envelope. It could mean the three cards are spread across players who weren’t asked (because an earlier player already disproved).
• Racing to the same room every turn. Staying near secret passages gives you flexibility to cover two rooms quickly.

Strategy Tips for Winning Clue

1. Make Suggestions that include your own cards. If you suggest “Miss Scarlet, in the Kitchen, with the Candlestick” and you already hold the Candlestick card, you know any disproof must relate to Miss Scarlet or the Kitchen. This focuses your deduction.
2. Watch who can’t disprove carefully. Every time a player says “I cannot disprove,” you learn something. Note it. Absence of information is still information.
3. Don’t stay in rooms you’ve already fully gathered info from. Once you’ve confirmed all the weapons or suspects that pass through a room, move on.
4. Use secret passages aggressively. They let you cover the board faster without rolling the dice. Study-to-Kitchen and Lounge-to-Conservatory routes are invaluable.
5. Listen to other players’ Suggestions. Even when it’s not your turn, track what’s being suggested and who disproves it. This gives you free information.
6. Don’t rush the Accusation. In most games, you’ll be able to narrow it down to the final solution through 4–8 well-placed Suggestions. Patience wins.

Quick Reference: Clue at a Glance

Two-Player Clue: Special Rules

Clue can technically be played with 2 players, but requires a modification: the remaining suspect tokens still move around the board based on dice rolls (or random movement), but they don’t make Suggestions. In practice, most players either use a “dummy hand” system — dealing the extra cards face-up or face-down in the centre — or simply play with 3+ players for the best experience. The game loses some deduction depth with fewer players since there are fewer people to watch for disproof patterns.

Frequently Asked Questions

Do you have to be in the room to make an Accusation?

No. Suggestions require you to be in the room you’re suggesting — but an Accusation can be made from anywhere on the board at any time during your turn. This surprises many players who have been “racing” to specific rooms to accuse.

Can you make a Suggestion without moving?

Only if you’re already in a room at the start of your turn. You can choose not to roll and stay in your current room, then make a Suggestion about that room.

What happens if all players have been eliminated?

If all players make wrong Accusations and are eliminated, nobody wins. The Case File is revealed and the mystery goes unsolved. This is rare but can happen in highly competitive play.

Can you suggest a suspect you know isn’t guilty?

Yes — Suggestions are tools for gathering information, not assertions of guilt. Suggesting a card you already hold is a valid and useful strategy.

What if someone else’s token is blocking a doorway?

In standard rules, tokens don’t block doorways. You can enter a room regardless of other tokens there. Some editions vary on this, so check your specific rulebook.

How many times can you visit the same room?

As many times as you like, but you can only make one Suggestion per visit (per turn). Once you’ve made your Suggestion for a visit, you won’t gain new information from the same room until you leave and return.

Conclusion

Clue is a masterclass in deductive reasoning wrapped inside a murder mystery atmosphere. When everyone knows the rules — especially the distinction between Suggestions and Accusations, and how disproving works — it becomes an intensely satisfying logic puzzle that rewards careful note-taking and sharp observation. Whether you’re playing the classic version or one of the many themed editions, the core experience is just as compelling today as it was seven decades ago.
