How to play Reaction Challenge
Take a moment with Reaction Challenge before moving to another game. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Choose a clear next step rather than rushing through the instructions. Make your first input carefully and watch the result. Keep the game area visible while you use its controls.
Review a difficult moment
When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round. 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. Take a moment to understand the current position.
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. Read a button’s label before selecting it. 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. Compare this with the rule that governs the move. Read the matching step again.
Watch out for this
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. A different version of the game may use a different rule. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
