Cluedo is an Australian whodunnit game show based on the British series of the same name and inspired by the 1949 board game Cluedo. It was produced by Crawford Action Time (a collaboration of Crawford Productions and Action Time) in conjunction with Nine Network. The show saw a studio audience view a dramatised scenario, then complete rounds of interrogating the six suspects on stage in character and viewing further evidence through a pre-recorded criminal investigation. Players then deduced the solution to the murder case using a trio of computer-linked electronic dials (whodunnit, whatdunnit, and wheredunnit), and after the solution was revealed the first person who had locked-in this combination won a prize.
