Play the classics. Meet yourself.
Interactive experiments from game theory, behavioural economics and cognitive psychology — and a profile built from how you actually play.
Play the experiments
Prisoner's Dilemma, the Ultimatum Game, Monty Hall, Stroop, Asch conformity — the studies that built behavioural science, rebuilt as games worth playing.
Every choice is data
Not just whether you cooperated, but how fast, after what, and whether you changed your mind. The signal is in the pattern, not the score.
Meet your profile
Your play projects onto nine dimensions, built up across every session. Watch it move as you learn — or as you fail to.
Nine dimensions
Each experiment measures something different. These are the axes they all report to — the reason this is a profile rather than a pile of high scores.
Prosociality
How much you give when giving costs you something.
Reciprocity
How you answer cooperation and betrayal — forgive, or retaliate.
Fairness
How much a just split matters when an unfair one would pay you more.
Risk Appetite
How readily you act when the outcome is uncertain.
Rationality
How well you follow the evidence when instinct pulls the other way.
Impulse Control
How reliably you can stop an action you've already started.
Independence
How much you hold your own view when the group disagrees.
Moral Style
Whether you judge an act by its consequences or by the rule it breaks.
Calibration
Whether your confidence matches how often you're actually right.
