A strategy game for two or more players, with two levels of difficulty. Using deductive reasoning and logic, the "decoder" must break the "secret code" devised by the other player in the fewest attempts. Then it is the first player's turn to create the most complex combination of colors possible, so that it cannot be decoded. The enclosed illustrated leaflets show the different levels of difficulty of the secret code, which can consist of 4 or 5 positions, using the 8 available colors.
