The goal of each agent in Inkognito is to complete a mission, together with his partner. At the beginning of the game, however, players don't know which mission they must fulfill!

In the standard four-player game, each player guides one of four secret agents. The four characters are allied in pairs: Lord Fiddlebottom and Colonel Bubble are always partnered against Agent X and Madame Zsa Zsa. Each of the four agents is represented by one of four different figures, with different builds: tall, short, fat, thin. Only one of them represents the actual character controlled by a player. The other three figures represent spies which are friendly to him and that are trying to confuse the opposition.

On a turn, a player shakes the Phantom of Prophecy randomizer to determine his three available actions, e.g., moving on a land route or a sea route. The player moves his figures, trying to reach spaces already occupied by the other players' figures or the Ambassador.

When figures are in the same space, the current player gets the right to "ask questions" and inspect some of the cards of that player. By deduction and a logical process of elimination, he can draw conclusions as to the identity and intentions of the other players.
