How to play Reaction Challenge
Make Reaction Challenge your next activity in the game library. 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. Read the objective before making your first input. Keep the game area visible while you use its controls.
Focus on one rule
Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow. Use the example to check your reasoning.
Your goal
Finish five valid responses. An early click does not count as a completed response; start that attempt again. Keep that objective in view throughout the round. Notice how the game responds to your input.
Step by step

- When GO appears, click or tap the large target.
- Read your response time and start the next round.

Controls

A useful example
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. Check the stated objective.
Watch out for this
Browser scheduling, screen refresh and input hardware can affect the measurement. It is not a medical test. A different version of the game may use a different rule.
