This app is one of the games for participants in the TEDS 21 study. Please see your invitation for details, or look at our website: http://www.teds.ac.uk

For most of the study activities, you will need the main TEDS21 app to be installed, too. If you don't have it already, you can find it here: https://play.google.com/store/apps/details?id=com.kingscollege.teds

If you would prefer to use a desktop or laptop computer, you can participate using the web version instead here: https://app.studies.teds.ac.uk
