THE PLAYBOOK · ZHOUSIMIAN
Learn your way around Reaction Challenge
Use a short break to learn the rhythm of Reaction Challenge. Finish five valid responses. An early click does not count as a completed response; start that attempt again. Look at what changes after your first action. Treat the first round as a chance to learn the controls. Choose a clear next step rather than rushing through the instructions.
A focus for your next round
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.
What you are aiming for
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. Check the rules when you are unsure.
How a round unfolds
- 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.
Keyboard and screen controls
Use the on-screen controls with a mouse or touch. Keep the playing area visible while using these controls. Contact us with the game and device if a control does not respond.
An example before you play
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. Read the matching step again.
Notice this detail
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. Before your first action, say what you are trying to achieve. Then compare the result with the goal.
