This is a list of episodes of the British version of the Cluedo TV series.

Series

Series 1 This first series, hosted by James Bellini, set had a blue and white theme with the suspects having to walk down ramp and steps to arrive at their seats with the teams sitting in a high rise area with white triangular desks. In this series, each team is made up of one celebrity and an expert in a field linked to the murder in some way. As well as the Christmas special, there are 300 members of the studio audience to which some are seen in the background risers behind the teams and the suspects and vote halfway during the show to see whom they think the killer was. This is the only series where Rev. Green was the only suspect not to be the killer in any of the episodes while Mrs. Peacock was the killer twice. But this is also the only series where the poison is used as the murder weapon twice and a choice of the murder weapons in all of the episodes. This is also the only series where the dining room is the murder room in some of the episodes. In episodes, suspects' reasons for murder are not present or relevant.

This is the only series where Mrs. White's husband, Mr. White is seen. From the next series onwards, Mrs. White is a widow. Mr. White was never a suspect and he lived with Mrs. White in an annex building next to where Mrs. White worked. He is also only seen with Mrs. White. In such scenes, they called each other "Mr. White" and "Mrs. White", respectively. As a result, Mr. White's first name is never revealed.
