THE PLAYBOOK · JYYJHG
Learn the rules of Reaction Challenge
Bring your attention to one round of Reaction Challenge. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Choose a clear next step rather than rushing through the instructions. Compare the starting position with the example in the Guide. Keep the game area visible while you use its controls.
One thing to notice as you play
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. Notice the feedback after each input.
The goal to keep in mind
Finish five valid responses. An early click does not count as a completed response; start that attempt again. Read that aim before choosing your first action. 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. On a smaller screen, keep the active part of the board within view. Use the visible help when you are unsure of the next input.
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. Verify the rule before continuing.
Keep this in mind
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. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
