How to play Reaction Challenge

Start Reaction Challenge by looking at the playing area and its controls. 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. Begin with the solo mode shown on the page. Keep the game area visible while you use its controls.

A useful comparison

Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Make the next step deliberately.

Your goal

Finish five valid responses. An early click does not count as a completed response; start that attempt again. Read that aim before choosing your first action. 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. A careful first action helps you become familiar with the layout. Look at the feedback after the action.

A useful example

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. Take a moment to compare.

Watch out for this

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. Keep the stated aim separate from side details such as animation or appearance. Progress is measured by the game’s own completion or scoring rules.
