The Imitation Game war (and the puzzle was not set by Turing, who was no good at them). Google, which sponsored the New York Premiere of the film, launched a competition called "The Code-Cracking Challenge" on 23 November 2014. It is a skill contest where entrants must crack a code provided by Google. The prize/s will be awarded to entrant/s who crack the code and submit their entry the fastest. In November 2014, ahead of the film's US release, "The New York Times" reprinted the 1942 puzzle from "The Daily Telegraph" used in recruiting codebreakers at Bletchley Park during the Second World War.
Enigma machine indicator procedures were two of the main weaknesses that made cracking Enigma possible. One of the earliest "indicator procedures" for the Enigma was cryptographically flawed and allowed Polish cryptanalysts to make the initial breaks into the plugboard Enigma. The procedure had the operator set his machine in accordance with the secret settings that all operators on the net shared. The settings included an initial position for the rotors (the "Grundstellung"), say, "AOH". The operator turned his rotors until "AOH" was visible through the rotor windows. At that point, the operator chose his own arbitrary starting position for the message he
