Hunch is a collection of short behavioural experiments played with real NIM.
Make a decision. Predict what another person will do. Then find out.
Your result isn’t a personality test. It’s a chance to see how well your prediction matched another human’s choice.
When an experiment has a meaningful benchmark, we compare your result with other Hunch players and published behavioural research.
Every round gives you another decision to make, another person to predict, and another result to compare.
