In the game, you have to take on the role of a detective. You are presented with a number of clues, one per person in the puzzle, and you have to deduce the whole puzzle by eliminating everyone who does not satisfy the puzzle requirements.

The game is based on an original, famous logic problem that is the basis of several puzzles. The game takes place in a fictional town where you have to establish the identity of a person based on a set of clues.

In the game, you can find three levels, where the level one is the easiest. The first level is to identify all the people, which requires just that. The second level is to identify the right person and guess his job, and the third level is to determine the whole puzzle.

The puzzles will ask you to find out the name of a person that has a certain attribute, or to identify the attribute of a person that has a certain name.
