Strategic Choice Engine

Game theory
decision simulator

Model a real decision as a strategic interaction. Enter the options, incentives, trust, repetition, information quality and power dynamics, then get a ranked recommendation using Nash logic, minimax safety, Pareto improvement, signalling, commitment, repeated-game cooperation and regret analysis.

Educational decision support only. This tool structures strategic thinking; it does not replace professional legal, financial, medical, employment, safety or geopolitical advice.

Strategic theatres

From tiny everyday coordination problems to massive geopolitical brinkmanship, the same strategic logic scales up — but the stakes, commitment devices, information gaps and downside risks change radically.

Strategic diagnosis

    Move design

      Interpret the output as a strategic briefing. For high-stakes or safety-critical decisions, use this as preparation before consulting a qualified professional or trusted human adviser.

      DC payoffs
      DD payoffs

      Each cell takes two numbers: first is your payoff, second is the other side’s payoff. The analyser identifies best responses, pure-strategy Nash equilibria, Pareto outcomes and likely doctrine.

      Concept map

      The simulator blends these concepts into a practical heuristic. “Best” means strategically robust under the information supplied, not morally perfect or guaranteed.
