Game theory puzzles quant interview guide for players, payoffs, information, best responses, optimal play, examples, and mistakes.
Candidates practicing incentives, equilibrium intuition, and optimal play.
Strategic puzzles need players and payoffs
Before solving a game-theory puzzle, define players, choices, information, payoff, and whether moves are simultaneous or sequential.
Best responses drive reasoning
A player chooses based on what they believe others will do. Best-response thinking can simplify a puzzle without requiring full formal equilibrium notation.
Concrete example
In a bidding puzzle, the value of a bid depends on how other participants respond. A strategy that looks good alone may fail after accounting for incentives.
Information matters
Common knowledge, hidden information, and signaling can change the solution. State what each player knows at each decision point.
Common mistakes
Candidates often optimize one player in isolation. A strategic puzzle requires checking how the other players would react.
