Interpreting a Payoff Matrix: Rows, Columns, and Cells
A payoff matrix is a standard format used in game theory to represent the outcomes of a strategic interaction. It consists of a rectangular array of numbers where one participant is designated the 'row player' and the other is the 'column player'. By convention, the first number in each cell of the matrix indicates the payoff for the row player, while the second number is the payoff for the column player. Each cell corresponds to a unique combination of strategies, showing the outcome for both players in that specific scenario.

Identifying Row and Column Players in the Anil and Bala Game
The table below shows the potential outcomes for two individuals, Player 1 and Player 2, based on their simultaneous choice between two actions: 'Action A' or 'Action B'. Player 1 is the 'row player' and their choices are listed down the side. Player 2 is the 'column player' and their choices are listed across the top. In each cell, the first number is the payoff for Player 1, and the second number is the payoff for Player 2.
Player 2: Action A Player 2: Action B Player 1: Action A (10, 8) (5, 12) Player 1: Action B (15, 6) (8, 10) If you know that Player 1 will choose 'Action B', what is Player 2's best choice to maximize their own payoff?
