The Game
7 players.
6 of you are drug dealers. 1 of you is an undercover narcotics officer.
Objectives
You play the game by making Deals with other players. The more players are involved in the Deal, the more lucrative it is for all sides.
Among drug dealers, only one player can win.
The scoreboard is private information.
Day Actions
The Day ends when everybody has declared an action and responded to all proposed Deals that involve him.
Nothing - You can choose to do nothing.
Deal - You can propose or agree to a Deal with other players. This is finalized when all parties agree on those involved.
Disappear - You exit the game with whatever points remain to you. You are immune to all actions for the rest of the game.
Night Actions
Investigate - You have a 50% chance of discovering whether or not someone is a cop or an informant, a 50% chance of discovering how many points someone has, and a 50% chance of discovering who that person has killed (if anyone). (You either discover the truth, or are notified that you didn't discover anything.)
Shakedown - You discover whether or not somebody is a cop or an informant, you discover how many points that person has, and you discover who that person has killed (if anyone). However, that person knows that you know his status.
Hit - Once per game, you may kill another player. You take all of that person's points. It is declared in the thread that someone was killed, but not who the culprit was. If you hit the cop, you are both removed from the game, but informants remain in play.
Arrest (Cop only) - Choose any number of players that have Evidence against them. Those players are given a choice: either they secretly become informants, and will now win if the cops win, or they "take the years" and refuse to become informants, in which case they are removed from the game at the start of the next day as though they had Disappeared normally. In either case, these players do not discover the identity of the cop.
Deals
Players earn points by proposing and agreeing to Deals with one another.
A Deal between 2 players nets each of them 1 point.
A Deal between 3 players nets each of them 3 points.
A Deal between 4 players nets each of them 7 points.
5 players, 15 points. 6 players, 31 points. All 7 players, stop being douchebags.
If a cop or an informant is included in a Deal, then all non-informant players involved in the deal have Evidence against them.
Victory Conditions
The cops win if all surviving players are informants.
Among those players who Disappear, the player with the most points wins.
