About the game
A short run with a reason to restart.
Reaction Loop is a one-button reflex game. Hold your nerve while the signal is red, then react the instant the cabinet flashes lime. Five rounds decide your average.
How to play
- Press Start run to begin a five-round session.
- Wait while the signal reads Hold.
- Tap or press Space as soon as the screen turns lime.
- Finish all five rounds to record your average reaction time.
Play better
- Rest your finger close to the button before each round.
- Watch the whole signal panel instead of the countdown text.
- A false start adds a penalty, so guessing is rarely worth it.
FAQ
Quick answers.
What is a good reaction time?
Around 200–250 ms is a strong everyday result. Device, browser, display, and input latency all affect the score, so compare runs on the same setup.
Does the game save my best score?
Yes. Your best average is stored locally in this browser. It is not uploaded to an account or cloud service.
Can I play on mobile?
Yes. Reaction Loop supports mouse, keyboard, and touch controls.
