Many players mistakenly believe that anyone can show a card to disprove a suggestion, but the rules specify a strict order of players.
According to the Hasbro Official Rulebook, the player immediately to the left of the person making the suggestion is the first to attempt to show a card.
When a player enters a room and makes a CLUE question regarding a suspect, weapon, and the room, the player on their left must be the first to try to answer. If that player possesses any of the cards mentioned in the enquiry, they must show exactly one card to the player who made the suggestion secretly. They should never show more than one card. If the player on the left cannot answer, they say 'I cannot answer' and the enquiry passes to the next player in turn until a card has been shown (Cluedo Instructions, [page not specified]).
Step-by-Step
Step 1: The player enters a room and makes a CLUE question about one suspect, one weapon, and the room.
Step 2: The player to the left of the questioner attempts to show one relevant card secretly.
Step 3: If the player to the left has no matching cards, the enquiry passes to the next player in turn.
Step 4: The process continues until one player successfully shows a single clue card to the questioner.
Example Play Situation
Alice enters the Library and asks, 'Was it Mustard, with the Wrench, in the Library?'. Bob, sitting to Alice's left, looks at his cards and shows Alice the Wrench card secretly. Alice then marks the Wrench off her CLUE sheet.
