Reflexes don't lie. Reaction Grid puts yours to the test in the most direct way possible: a tile glows somewhere on the screen, the countdown is already running, and your only job is to tap it before time expires.
The rules take seconds to understand. A grid of dark tiles fills the screen and one of them lights up. Tap the correct tile within the time limit and your score climbs. Tap the wrong one, or let the timer expire before you react, and you lose a life. Three lives stand between you and the end. When they run out, the game over screen appears with a full breakdown of how far you made it: level reached, correct taps logged, and your best score updated if you managed to beat it. Each run tells you exactly where you stand.
