6. Cluedo
One of the first board games to surpass the magic billion-dollar revenue, British board game Cluedo (a play on ‘Clue’ and ‘Ludo’ which means ‘I play’ in Latin), centers on the unfolding of a murder of Dr Black (Mr Boddy in the North American version known as ‘Clue’) within an aristocratic manor house. The only entry in our list of most sold board games to involve a murderous element, contestants have to piece together the events, and put forward their deductions as to who committed the murder, and with what weapon. The solution is held within an envelope in the center of the board and is only opened when a contestant makes their ‘accusation’. The ultimate murder-mystery game has sold over 100 million copies since it was launched in 1949.
