Definition:Payoff Table/Zero-Sum

Definition
Let $G$ be a two-person zero-sum game.

A payoff table for $G$ is an array which specifies the payoff to (conventionally) the maximising player for each strategy of both players.

As $G$ is zero-sum, there is no need to specify the payoff to the minimising player, as it will be the negative of the payoff to the maximising player.

$G$ is completely defined by its payoff table.

Also known as
A payoff table is also known as a payoff matrix.

Some sources hyphenate: pay-off table or pay-off matrix.
