P.I.是一个纯粹的演绎游戏，玩家在三个连续的迷你游戏中进行比赛，以了解谁在解决他们的案件中获得了最佳的排名。

每一个迷你游戏都是一样的。首先，你会收到一个秘密的嫌疑人卡(12个)，一个犯罪卡(10个)，一个位置卡(14个);这组信息代表了你左边的玩家必须解决的问题。游戏板显示了14个位置，每个位置都有一些其他的位置;每个地方都有犯罪嫌疑人和犯罪嫌疑人的空间。将可疑的瓷砖(12个，再加上两个“无嫌疑犯”)和犯罪片(10个，加上4个“无犯罪”)进行洗牌，然后在每个地方放置一张脸。每一名嫌疑人、犯罪和地点都被包括在一副证据卡中，并且有九张证据卡被揭露。

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.

Each mini-game plays out the same way. To start, you receive in secret one suspect card (out of 12), one crime card (out of 10), and one location card (out of 14); this set of information represents the case that the player to your left must solve. The game board shows fourteen locations arranged so that each location touches a few others; each location has space for a suspect and crime tile. Shuffle the suspect tiles (12, plus two "no suspect") and the crime tiles (10, plus four "no crime"), then place one face up in each location. Each suspect, crime and location is included in a deck of evidence cards, and nine evidence cards are revealed.
