The Psychology of Play: Why Scavenger Hunts Work

Opinion, not a lab paper
This is an explainer for organizers. It cites well-known psychology concepts as design metaphors, not as a clinical trial of products.
Autonomy, competence, relatedness
Choice of route, achievable early wins, and real teamwork. Any platform that only supports a rigid single path is working against autonomy.
Flow and variable tasks
Mix difficulty and format. Adaptive or optional bonus tasks exist on more than one vendor; the principle is older than any of them.
Unfinished business
Progress counters work because incomplete tasks stay salient. Use them; do not spam notifications.
Takeaway
Buy software that can express these mechanics. Do not buy a story that only one logo owns play psychology.
