Reaction Challenge: how a round works
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. Check the relevant rule before repeating a move. Read the objective before making your first input. Choose a clear next step rather than rushing through the instructions.
Bring this focus to a round
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. Make the next step deliberately.
The objective of a round
Finish five valid responses. An early click does not count as a completed response; start that attempt again. The feedback beside the game helps you follow the round. Follow this game’s rules rather than another version’s.
The order of play
- 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. On a smaller screen, keep the active part of the board within view. Return to the rules if the result is unexpected.
See how the rules apply
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. Verify the rule before continuing.
An important reminder
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. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
