Which board game was originally named "Murder"?

Clue was first invented in 1943 and began selling in the U.S. in 1949. Invented during World War II, this best-selling board game has a lot of history and some interesting trivia behind it. Anthony Pratt’s concept version of the game was initially named ‘Murder.’ Still, it was later changed to Clue or Cluedo when it was published by Waddingtons in 1949. Pratt’s original concept version of the game included eleven rooms, including the gun room, nine different weapons, and ten characters.
