Who Paid for the Taxi

The first board defines a game by players, moves and payoffs, each player choosing alone. This lesson changes the question: players can team up and share what they win together, and the game is about how to split it.

Before you start. From What Is a Game? you have a game: what you get depends on what others do too. From Who Gets the Bigger Slice you have bargaining between two people: each gets what they could get alone, plus a share of what the deal adds. Here there are three or more people, and any group of them could break away and do its own deal.
