Game Theory Tool

Use this interactive tool to explore classic examples and find Nash Equilibria:

How to Use

• Row Player (on the left) chooses a row
• Column Player (on the top) chooses a column
• Each box shows the outcome: (Row Player's payoff, Column Player's payoff)

Try selecting different examples from the tool's dropdown menu (like the famous Prisoner's Dilemma) to see how different choices lead to different rewards.

Nash Equilibrium

Named after mathematician John Nash, a Nash Equilibrium is a state where no player can get a better result by changing their choice alone.

Game Theory

Game Theory can help us find the ...

• best decision in a competitive situation, or
• fairest decision in a cooperative situation

... where the outcome for each player depends on their decision and the decisions of other players.
