Bounce Ball
Keep your cursor inside the bouncing ball. It speeds up every 5 seconds. How long can you stay on target?
How it works
A ball bounces around the screen with full physics — it deflects off all four walls. The challenge ramps up: every 5 seconds the ball speeds up by 60 px/s, from a comfortable 280 px/s up to a maximum 700 px/s. The speed bar at the top of the play area shows you where you are in the ramp.
How it differs from the tracking test
The tracking test uses a smooth, predictable Lissajous path — it trains anticipation and steady wrist control. Bounce Ball is unpredictable (bounces change direction sharply) and gets progressively harder, which trains reactive tracking and sustained concentration under pressure.
