Strategy: The strategy for playing cluedo is to find out who the killer is. To do this you must throw the dice and try and get to each room, once in those room you must create rumours to find out if any other players have the cards of the rumour you have just made up, if any of them do then you can cross out that card on your sheet, until you come to a point where you know who the killer is.
Information set: The information that you get when playing cluedo is that each player will give you the answer to your rumour that you have just said, for example if you say, Plum with the bat in the guest room, if anyone has either of them cards they must show you discreetly without any other player seeing the card.
Payoff: The payoff that you get at the end of playing cluedo is that you have beaten everyone to find out who the killer was.
