Controls
A Nash equilibrium is a pair of strategies where neither player can do better by unilaterally changing — the cornerstone of game theory. In the Prisoner's Dilemma both defect even though cooperating pays more; Matching Pennies has no pure equilibrium at all. Highlighted cells are the pure-strategy Nash equilibria.

About this simulation
The full Auction Designer tool models a price war with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
