Project: Experiment on the perception of randomness

We would like to invite you to play a web game. The game is part of a research project which studies how humans see random data.

You must be at least 13 years old to play this game.

It is your decision to play this game. Even if you begin playing, you can stop at any time. If you do play, your mouse clicks will be recorded as part of the research information.

No publication based on this research will identify you as a player. Also, we will not be able to know what your IP address is.

There are no risks to you for playing. There are no benefits to you from playing. But your input may help us learn more about how humans see random data.

We may award prizes, approximately once a month, to the top-scoring players who participate in this game project. To find out what the prizes are, go to the game website. If you win, you will receive your prize via email.

If you have any questions about this game, please call Emanuele Viola at 617-373-8298 or write to
