How to play Reaction Challenge
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. Choose a clear next step rather than rushing through the instructions. Identify the playing area and the controls you need. Use the example below to understand a decision.
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. Keep the objective visible.
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. Return to the instructions when a step is unclear.
Step by step
- 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.
Controls
Use the on-screen controls with a mouse or touch. On a smaller screen, keep the active part of the board within view. Avoid pressing the same control repeatedly while a move is being processed.
A useful example
A valid 250 ms response counts. Clicking during WAIT is too early and must be repeated. Compare this with the rule that governs the move. Verify the rule before continuing.
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. 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.
