How to play
Study the marked balls for as long as you need. When you are ready, they all look alike and move. Select the original targets once they stop. There are five trials; a trial is correct when you find every target and no others.
Use touch or a mouse, or Tab to move between controls and Enter or Space to select.
This is a visual tracking practice. Motion is essential; it begins only when you choose. It is not a clinical attention test.
