In Master Detectives: Code X, players take on the role of master sleuths who want to determine once and for all who the best detective is. Each detective composes a secret code for one of their opponents and tries to decipher their own code through clever detective work. Tactically move your detective across the game board to reach the desired location and gather the correct information, or to interrogate your opponents about your code. The first player to crack their assigned code wins this exciting code-breaking game.
