Coreball
A ball sweeps up and down the track — tap the instant it crosses the green zone. Dead-center hits score triple, consecutive hits multiply your combo, and every hit makes the ball faster. Three misses and the run is over.

How to play
Click or tap anywhere on the board while the ball is inside the green zone. Your points depend on precision — a hit near the dashed centerline scores Perfect (100), the middle band scores Great (50), and the edges score OK (25) — multiplied by your current combo. Every hit relocates the zone, shrinks it slightly, and speeds the ball up.
The trick: don't chase the ball with your eyes — watch the zone and let the ball come to you. The ball moves on a smooth wave, so its rhythm is learnable: it lingers at the top and bottom of the track and whips through the middle. Zones near the ends of the track are gifts; zones in the middle are where combos go to die. Patience protects your lives — there's no penalty for letting the ball pass through the zone without tapping.
