The rules

Start the trial, wait without anticipating, and respond the moment the visual signal turns green. An early click ends the attempt.

What makes it different

Everyone gets the same daily wait, making the result easy to compare while the response adapts to just how extraordinary—or leisurely—your reaction was.
