How to play Reaction Challenge

Open Reaction Challenge, check the instructions and begin a round. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Keep the game area visible while you use its controls. Begin with the solo mode shown on the page. Use the example below to understand a decision.

Make the controls familiar

Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart. Refer to the controls when needed.

Your goal

Finish five valid responses. An early click does not count as a completed response; start that attempt again. Read that aim before choosing your first action. Start with a deliberate move.

Step by step

  1. Start a round and wait without clicking.
  2. When GO appears, click or tap the large target.
  3. Read your response time and start the next round.
  4. After five rounds, the game shows the mean time.

Controls

Use the on-screen controls with a mouse or touch. A careful first action helps you become familiar with the layout. A new-round button replaces the current round.

A useful example

A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated. Focus on why the action is allowed, not only its outcome. Take a moment to compare.

Watch out for this

Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. Compare the situation with the worked example. Locate the buttons and input area before beginning a long round. Use the on-screen labels to avoid an accidental restart.
