How to play Reaction Challenge
Reaction Challenge gives you a focused activity to play in your browser. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Look at what changes after your first action. Use the opening round to become familiar with the layout. Check the relevant rule before repeating a move.
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. Keep the objective visible.
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. The example below illustrates a decision.
Step by step
- Start a round and wait without clicking.
- When GO appears, click or tap the large target.
- Read your response time and start the next round.
- 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. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated. Use the example as a guide rather than a substitute for reading your board. Keep the game’s format in mind.
Watch out for this
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. Check the rule before repeating the action. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
