A "zero sum" game is simply a win-lose game such as tic-tac-toe. For every winner, there's a loser. If I win, you lose. Non-zero sum games allow for cooperation. There are moves that benefit both players, and this is what makes these games interesting.

For the purpose of this game, it makes no difference whether or not you or Albert actually committed the crime. You are both told the same thing:
• If you both confess, you will both get four years in prison.
• If neither of you confesses, the police will be able to pin part of the crime on you, and you'll both get two years.
• If one of you confesses but the other doesn't, the confessor will make a deal with the police and will go free while the other one goes to jail for five years.
