About Reaction Timer
A reaction time test measures how quickly you respond to something you see. Gamers, athletes and drivers all rely on fast reactions, and it is fun to see how yours compares — and how it changes when you are tired, rested or focused.
Reaction Timer gives you five chances to set a fast time. Each round is worth more points the quicker you tap, so a calm, focused finger beats a nervous one. The waiting time is random, so the only way to win is to really react.
How to play Reaction Timer
- Press Play and wait. The screen stays dark for a random moment.
- The moment it turns green, tap or click as fast as you can.
- Your reaction time for that round is shown in milliseconds.
Rules
- A game has 5 rounds.
- Tap before the screen turns green and you lose a life. You have 2 lives.
- Faster reactions give a higher score.
Tips to win
- Rest your finger just above the screen or mouse button.
- Watch the whole screen, not one spot.
- Do not guess the timing — the wait is random, and an early tap costs a life.
- Play when you are rested: tiredness slows reaction time a lot.
