Understand the basics of Reaction Challenge
Start Reaction Challenge by looking at the playing area and its controls. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Use the example below to understand a decision. Identify the playing area and the controls you need. Check the relevant rule before repeating a move.
Something to practise
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Make the next step deliberately.
What you need to achieve
Finish five valid responses. An early click does not count as a completed response; start that attempt again. Use the instructions to see which actions move you towards it. Check the rules when you are unsure.
Work through the instructions
- 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.
How to use the controls
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. A new-round button replaces the current round.
Try this 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. Verify the rule before continuing.
Where a round can go wrong
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. After a move, check what changed. Decide which rule explains the new state before acting again.
