How to take part?
Taking part in these experiments is easy. All you have to do is to read the instructions of the currently active experiment, perform what the experiment asks you to do and fill the form to submit the results.
The results that you submit are anonymous but you're asked to fill in your gender, what technique you used to perform the experiment and your subjective estimation of your skill level. The reason for these is that it's interesting to know if different groups of people have different levels of abilities.
You are also asked to fill in your age, name and email address but these are optional. Participant who enter their email address are eligible to win the prizes at the end of each experiment and get subscribed to the announcements newsletter. If you win one of the prizes you'll be contacted at that email.
Some of the experiments will only be available to registered users as they will include interaction between subscribers.
So, don't wait and subscribe to the newsletter using the form below and go to current experiment.
