Be the first to tap when the circle turns green. Win 3 rounds to win the match. But be careful — if you tap before the signal, you lose the round automatically!
First to 3 points wins the match (best of 5). Each round, the fastest reaction after the green signal wins a point. Tapping early is a fault and gives the point to your opponent.
Focus on the circle, not the timing. The delay is random (2-5 seconds) so you can't predict it. Stay calm, wait for green, then tap as fast as possible!
