The other day, I got a spark. I have decided to invent a drinking game. A drinking game based on the prisoner’s dilemma. The game will be played with cards. I havn’t worked out all the details, but the game will be called “Rat” and will based on whether the players decide to “Rat” each other out or not. I’ve outlined what I have so far below:
The game is played by three or more players: Player A, Player B, and the Interrogator.
The Interrogator, who deals the cards, is selected at the beginning of the game, and moves clockwise. If more than three players are playing, the Interrogator may choose to which players the cards are dealt.
Each player is dealt a card by the interrogator, and a third card is played, down, to the middle. The players do not know the value of each other’s card, or the middle card.
Player A
Player B

Quiet |
Both Players Drink the Value of the Middle Card. |
Player A Drinks Middle Card and Player B’s Card. |
|
Rat |
Player B Drinks Middle Card and Player A’s Card. |
Both Players Drink Double the Value of the Middle Card.
|
Each player has two motivations: to avoid drinking as much as possible, and to make the other player drink as much as possible.
Each player faces this dilemma:
If they (as Player A) play the card up, or “rats” then there are two possible outcomes:
Player B is quiet:
Player A has succeeded in both goals. Player B must now drink the value of the middle card plus the value of Player A’s card, and Player A does not have to drink. (Big Win, Big Lose)
Player B “Rats”
Both players must drink double the value of the middle card. Player A has succeeded in the goal of making Player B drink, but has failed the goal of not drinking his/her self. (Lose, Lose)
If they choose to remain quiet, they face the following possibilities:
Player B is quiet:
Both players must drink the value of the middle card. Player A has succeeded in the goal of making Player B drink, but has failed the goal of not drinking his/her self. (Win, Win)
Player B “Rats”
Player A must now drink the value of the middle card, plus the value of the middle card, while Player B does not drink. Player A has failed both goals. (Big Lose, Big Win)
In accordance with the rules of prisoner’s dilemma, the penaltiy ranking fits that Big Win > Win > Lose > Big Lose, assuming all card values are similar in value. As this will often not be the case, this may effect the way each hand is played.
As with the normal prisoner’s dilemma, playing only 1 round, both players are likely to “rat,” although this is not the optimum outcome for either, or both. However, at subsequent rounds, if players believe the other is likely to rat, they will also, even though this hurts them as well. Developing trust is the only way to avoid this, but that affords the players the opportunity to betray each other.
Additional modification to the penalties can be included, such as:
If both players ”rat” and both cards are face cards, then penalties double, and middle card is turned. If middle card is also face card, penalties tripple.
If one player ‘rats’ and the other is quite, and both the “rat” card and middle card are face cards, penalties double.
If one player ‘rats’ and the other is quite, and both the “rat” card and middle card are the same suite, penalties revert back to the “rat.”
I am very open to any suggestions on this. What do you think?
