💻 PC recommended - This training requires precise clicking and is best experienced on desktop/laptop with a mouse.
⚡ Quick start: Watch the circle move (straight, curved, or spiral paths possible). When it disappears, click where it will be after the prediction time! Motion can accelerate, decelerate, or stay constant. Press Space to pause anytime.

📖 Detailed instructions
Click the test area (or press Space) to begin.
A moving circle will appear and travel across the screen. Motion can be straight with bounces, curved, or spiral depending on your settings.
The circle can move at constant speed, accelerate, or decelerate based on your chosen speed variation.
The circle will be visible for your selected duration (short: 0.6s, medium: 1.5s, or long: 2.5s), then disappear.
Your task: Click where you predict the circle will be after the specified prediction time (1s, 2s, or 3s).
The circle continues moving during the invisible period with the same physics (curved paths keep curving, acceleration continues, wall bounces happen).
The closer your click to the actual future position, the higher your score.
Press Space to pause/resume at any time.
This advanced test measures your ability to mentally simulate complex object motion including curves, acceleration, and predict future positions - essential for sports, driving, and spatial reasoning.
Lower average error (in pixels) indicates better predictive ability.
