A quick 30-second browser reaction game. Tap each target as soon as it appears in a new position, then see your hits, fastest reaction and average reaction time. Play on desktop or mobile with no account or download.
Click or tap Let’s play. Wait for the coral target, then click or tap it as quickly as you can. Each hit moves the next target after a short random wait. Only target hits count; blank clicks do not count as reaction results. After 30 seconds, see your hits, best and average reaction time, then choose Play Again. This is a casual game, not a medical or scientific test.
