How to play Reaction Challenge

Reaction Challenge gives you a focused activity to play in your browser. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Keep the game area visible while you use its controls. Use the opening round to become familiar with the layout. Check the relevant rule before repeating a move.

Try a deliberate move

After a move, check what changed. Decide which rule explains the new state before acting again. Refer to the controls when needed.

Your goal

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. Follow this game’s rules rather than another version’s.

Step by step

1. Start a round and wait without clicking.
2. When GO appears, click or tap the large target.
3. Read your response time and start the next round.
4. 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. Check any mode label before starting.

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. Check the rule before repeating the action. Choose one rule to keep in mind for this round. Apply it consistently rather than guessing what another version might allow.
