About Reaction Time Test

Reaction Time Test (reactiontestgame.com) is home to our own free, browser-based Reaction Time Test. It measures how quickly you respond to a signal, in milliseconds, using short tests that take under a minute. No download, no account, and it works with a mouse, a keyboard or a touch screen.

The Reaction Time Test

• Reaction Time – wait for the red screen to turn green, then react. Five rounds, average in milliseconds.
• Audio Reaction – the screen stays dark and you react to a beep instead of a color change.
• Choice Reaction – one of two sides lights up and you must hit the correct side. Ten rounds; wrong answers lower your accuracy.
• Aim Trainer – click 30 targets as quickly as possible; the score is the average time per target.
• Daily Aim Challenge – 20 targets whose positions and sizes are generated from the date, so everyone plays the same layout.

Lower is better in every mode. Reacting before the signal counts as a false start and the round is repeated. Results depend on your device, screen and input method, so compare scores taken on the same setup. Best results are stored only in your browser.
