Players sit across a table from one another. A metal ball at the center of the table is moved by a hidden magnet. Players attempt to move the ball toward their opponent's goal by controlling their EEG activity, monitored through two headbands wired to a bio-sensor system; by relaxing their brains, and hence increasing their alpha and theta brainwaves, players cause the ball to roll toward the other side of the table. The most relaxed player will win when the ball reaches their opponent's goal.
