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. Choose a clear next step rather than rushing through the instructions. Use the opening round to become familiar with the layout. Look at what changes after your first action.
A useful comparison
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Keep the objective visible.
Your goal
Finish five valid responses. An early click does not count as a completed response; start that attempt again. Keep that objective in view throughout the round. Check the rules when you are unsure.
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. Use the control method described here for this activity. Make sure you are interacting with the game rather than the surrounding page.
A useful example
A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated. Apply the same reasoning to the position in your own round. Look for the relevant detail.
Watch out for this
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. Take a moment to reassess the position before continuing. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
