Use the example below to understand a decision. Choose a comfortable screen position before beginning. Use the example below to understand a decision.

Build familiarity through play

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. 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. An attractive position is not enough unless the goal is met. Try to explain the aim in your own words.

How a round unfolds

1. Start a round and wait without clicking.
2. When GO appears, click or tap the large target.
3. Read your response time and start the next round.
4. 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. 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. Take a moment to compare.

Notice this detail

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. Watch the feedback after an action. A message can explain whether the input was accepted or whether a rule needs attention.
