The ball disappears. Count the bounces.
A color-shifting ball bounces around the arena for 30 seconds. But the center zone is hidden — the ball disappears when it passes through.

Count the bounces from what you can see at the edges. Track the invisible.
Hidden zone: The central 50% of the arena is covered. The ball is invisible while passing through.

Watch: Count the bounces you see at the arena edges. Speed increases over time.

Guess: After 30s, pick the total bounce count from 5 choices.

Replay: The hidden zone is lifted — see the full path with bounce count.

Scoring: Exact answer = ✓. Wrong = ✗. Your best streak is saved.
