Alpha Charlie Tango 2018

Alan Turing, a brilliant mathematician, proved that intelligence can win wars by deciphering the German Enigma code during World War II. Likewise, in Alpha Charlie Tango, players have the challenge of uncovering their opponents' secret codes, deciphering each of their parts through a meticulous and strategic choice of which false messages to send, before they discover their code.

There are five possible characters, but several combinations, and each time a player sends a three character message, each of the other players signals the presence of these characters in their code (if there are equal characters, only one character must be signaled, which the mission of figuring out your code even harder). In turn, a person may try to deduce a part of the code from another person, but if he makes a mistake, he should reveal a part of his own code. Whoever is the only one still has hidden parts of his own code!
