The Reaction Challenge playbook
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. Use the example below to understand a decision. Compare the starting position with the example in the Guide. Look at what changes after your first action.
Build familiarity through play
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Refer to the controls when needed.
Aim for this result
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. Check the rules when you are unsure.
Follow these playing steps
- 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. Use the control method described here for this activity. Use one clear input at a time.
A useful 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. Consider the next action carefully.
A mistake to avoid
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. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
