P.I. is a pure deduction game, with players competing in three consecutive mini-games in order to see who's got the best chops in terms of solving their cases.

The mini-game ends once everyone has solved their case or only one case remains unsolved. All used investigators are removed from play, then the board and cards are reset for the next mini-case. Each player has only five investigators total, so use them wisely!

Whoever has the most points after three mini-cases wins.
