The Enigma Device - Version 1.2 This entertaining solo game has become a classic. The original versions of the game were inspired by "The Enigma Machine" which the Germans used to encode and decode messages. In this simplified JAVA version, a one-stage letter substitution is used to scramble a well-known or humorous quotation. Your task is to unravel the quotation by swapping letter pairs until the original message is restored. Two puzzles are provided daily. The solutions are revealed the next day.
