Tap the glowing port. Chain 5 hits. Activate Overdrive.
A 3x3 grid of neon ports lights up one at a time. Click or tap the glowing port before it fades to score. Let it expire or click the wrong port and lose a point. Chain 5 consecutive correct hits to activate Overdrive mode — ports cycle 1.5x faster and every hit scores double for 5 seconds.
