Reaction
Minimalist arcade game that challenges your reflexes. A 4×4 grid of circles sits in front of you — when one or more light up, tap them before they disappear! The game accelerates every few seconds: more circles activate at once and the time window shrinks. Miss a circle or tap the wrong one and it's game over. Rack up points, beat your high score, and compete on the global leaderboard.
How to Play
1. Tap "Play" to start a round. 2. You'll see a grid of 16 circles. Wait for one or more to light up white. 3. Tap each lit circle before its timer runs out — each successful tap scores one point. 4. Do NOT tap an unlit circle — that's an error and ends the game. 5. Do NOT let a lit circle time out — that's a miss and ends the game. 6. The longer you survive, the harder it gets: more circles activate at once and windows get shorter. 7. After losing, you can watch an ad to continue with your current score (once per session).
