With JATOS 2 you can run group studies. JATOS is versatile and supports fixed, two-user studies (like this Prisoner’s Dilemma) or open, multi-user studies (like this Snake game), and everything in between.

The easiest way to get started is trying out some pre-made examples. For this, you’ll have to run a group study as two different workers.
So you could:
- Download the Snake game
- Get a link for the first worker: Snake game -> Batch Manager -> Default batch -> Worker Setup -> Personal Multiple worker and ‘Add’ a new one. In the confirmation press ‘Run’ to start the study.
- Get the link for the second worker: in a second browser tab (or window), go to Worker Setup in the same Default batch and create a new Personal Multiple worker. Press ‘Run’ to start the study.
- In both browser tabs, click through the introduction until you arrive in the waiting room. Click ‘Join’ and then ‘Ready’.
- Voilà! You’ll see two snakes moving around: your own and the one from the other worker.
