How to Play
Mastering Reaction basics
Use your mouse or touchscreen to tap any circle that lights up white. You have to be quick because the timer is unforgiving. If you miss a circle or click a dark one, the round ends instantly. Knowing how to play Reaction means watching the whole grid, not just one corner.
Reaction controls and speed
The Reaction controls are straightforward—just tap to clear. The common mistake is trying to tap too fast and hitting an unlit circle by accident. Slow down just enough to stay accurate. As you progress, the game cranks up the speed until it feels like a total blur.
