Perceptle Track: predict the landing

Watch the beginning of a ball’s flight. After the ball disappears, click or tap the point where you think it will meet the floor. Your task is to continue the visible motion in your head, rather than follow a marker to its destination.

Read the flight before it disappears

Normal practice generates flights in both directions. Launch and landing positions stay within the useful board area, and the full flight lasts roughly 1.1–1.8 seconds. You see only the early part before making a prediction.

Wait until the ball has faded before answering. Select a horizontal position on the board; the score compares it with the generated landing, not with the point where the ball vanished.

Separate height from horizontal travel

Look at how quickly the ball moves sideways and how steeply it rises. A high arc can spend longer in the air, while a shallow-looking launch may have stronger sideways movement.

Use the floor as a reference, then imagine the remaining arc. Replaying several different flights is more useful than memorizing one screen position, because the next round changes the start, direction and landing.

Understand the landing error

Track measures the horizontal miss in logical board pixels. The board scales to the screen, so the reported pixels are game coordinates rather than a measurement of your device’s physical display. Compare other errors in the scoring examples.

In normal mode, misses of 30, 60 and 90 logical pixels score about 90, 69 and 50. Friday uses weaker gravity, wall ricochets and a wider tolerance; the reflected path matters when estimating its landing.

Questions and answers

Can the ball travel from right to left?

Yes. Normal random practice includes launches in either direction, so the landing is not always on the right.

Why did my early tap do nothing?

The test accepts a prediction after the visible flight and fade. This keeps the action tied to estimating the unseen remainder.
