7 KEYS · 20 TRIALS
See a target key. Press or tap the exact match before the timing bar empties.
Complete 20 trials. Wrong keys and timeouts count, then the game continues.
READY?
Keyboard: use A S D F J K L. Touch: tap one of the large keys below.
The timer starts when the target appears. Pressing keys during the short wait is ignored.
HOW TO PLAY
Start the test and rest your fingers near A, S, D, F, J, K, and L.
After a short wait, read the large target key and respond before the timing bar empties.
Finish 20 standard trials, or keep a perfect endless streak as the response window shrinks.
KEYBOARD REFLEX TEST
Each trial combines visual recognition with a seven-choice key response. The target always comes from the familiar home-row set A, S, D, F, J, K, and L.
This is a recreational browser game, not a clinical assessment. Keyboard hardware, touchscreen delay, display refresh rate, focus, and practice can change the result.
READ YOUR SCORE
Accuracy includes correct keys, wrong keys, and timeouts. Average and best reaction times use correct responses only.
Compare runs made on the same device and with the same input method. A physical keyboard and touchscreen can have different input delays.
QUESTIONS
The test uses A, S, D, F, J, K, and L. On a phone or tablet, tap the matching on-screen key instead.
Accuracy includes all responses and timeouts. Average and best reaction times use correct responses only.
Standard mode records it and continues until all 20 trials are complete. In endless mode, the first mistake ends the run.
Endless mode gives you one life. The response window shrinks from about 1.8 seconds toward 0.45 seconds as your streak grows.
