Your guide to 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. Use the example below to understand a decision. Treat the first round as a chance to learn the controls. Keep the game area visible while you use its controls.
Take a closer look while playing
After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.
The goal to keep in mind
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. Start with a deliberate move.
Making your moves
- 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.
Input guidance
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.
Work through an 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. Consider the next action carefully.
Check this before moving on
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.
