A game is a description of a social interaction, which specifies:
* The players: Who is interacting with whom
* The feasible strategies: Which actions are open to the players
* The order of play: When the players choose their actions

* The payoffs: What the outcomes will be for each of the possible
combinations of actions.

They know exactly what would happen in each possible outcome

response to the strategies of the other players is called a Nash equilibrium.
Usually if the game has one Nash equilibrium it is the best outcome
what is the pareto criteria

The Pareto criterion makes no value judgement beyond the least controversial one that an allocation is better if it makes at least one person better off and no one worse off.
