About

GameTactic

Features
Read full description

GameTactic leverages game theory to determine the best strategies, including dominant plays and Nash equilibria, in two-player normal-form games. Users can select from preset games like the prisoner's dilemma, pure coordination, battle of the sexes, rock-paper-scissors, and game of chicken. After selecting a game, GameTactic identifies its optimal strategies and equilibria, allowing users to adjust payoffs and evaluate their implications. Additionally, you have the flexibility to design a custom game, defining strategies and associated payoffs. Currently, our platform focuses on identifying strict dominant strategies and pure and completely mixed Nash equilibria, with plans to expand to weakly dominant strategies and for partially mixed Nash equilibria in future versions.
