Reaction Time is a reflex-testing game that measures how quickly you can respond to a visual stimulus. The screen changes color, and you must click as fast as possible.

The goal is to achieve the fastest reaction time possible. Your reaction time is measured in milliseconds. The faster you react, the more points you earn.

The challenge is maintaining focus and reacting quickly. False starts (clicking too early) are penalized. The best players stay calm and focused.

Our RetroPlayNow version features multiple rounds, average reaction time tracking, and a scoring system that rewards fast reactions. Every round earns Retro Coins.

How to play Reaction Time

  1. Wait for the color change. The screen will change from red to green. Wait for it.
  2. Click as fast as you can. When the color changes, click immediately. Your reaction time is measured.
  3. Don't click too early. Clicking before the color changes is a false start and is penalized.
  4. Improve your time. Try to beat your best reaction time. Practice makes perfect.
  5. Earn Retro Coins. Score points by reacting quickly. Faster times mean more Retro Coins.
