Features & Capabilities

Play fun mini-games to help brain scientists study the psychology and neuroscience of well-being!

Created by scientists at UCL and Yale, this app is a citizen science project taking psychology and neuroscience experiments from the lab to your smartphone.

Every 3-minute game that you finish contributes data to real scientific research about how the brain works. The anonymous surveys help us see what causes well-being and understand mental health conditions like anxiety and depression. Be part of a unique citizen science experiment and help us write the equation for happiness!

Dr Robb Rutledge (Yale Psychology) says: "We all want to know what determines happiness. It’s hard to figure it out! In our games, we ask people about their happiness as they make decisions in different situations. We hope people enjoy our app and help us answer some really important scientific questions!"

This citizen science project was supported by the UK Medical Research Council.

This game is a torture device of unhappiness.

These games are boring and should not be used to measure motivation to happiness. I am motivated to just get the game done as quickly as possible and that's about it :)
