All players play as thieves who are pulling bills out of a (literal) wallet stuffed with cash. What none of them know, is any player may be an undercover cop, trying to catch a thief in the act.
In Pickpockets, players will take turns either drawing or manipulating money cards in a wallet until any player reveals themselves as an Undercover Cop, yelling “hands up”. All other players will reveal their cards. The Undercover Cop wins if at least one other player has two or more marked bills in their possession. Otherwise the Pickpocket with the most money wins. Alternatively a player can skip town if they have at least $100 in their possession.
The bonus cards are 3 special ability cards featuring business cards of The Cleaner, The Pigeon and Kingpin.
