Build familiarity through play
Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention. Use the example to check your reasoning.
What you need to achieve
Finish five valid responses. An early click does not count as a completed response; start that attempt again. An attractive position is not enough unless the goal is met. Keep the controls in easy reach.
The order of play
- 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.
Keyboard and screen controls
Use the on-screen controls with a mouse or touch. Use the control method described here for this activity. Return to the rules if the result is unexpected.
One way to understand the rules
A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated. Your next round may have a different position, so inspect it before acting. Choose a deliberate next step.
A common point of confusion
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. Read the feedback to see why an action did not have the expected result. After a move, check what changed. Decide which rule explains the new state before acting again.
