How to play
- 1
Watch the laser bounce off moving mirrors.
- 2
Track where the beam is heading as mirrors shift.
- 3
Pick LEFT, CENTER, or RIGHT for the landing zone.
What this test measures
This game measures geometric intuition: predicting reflections and continuing a path after the motion gets messy. You apply angle-in, angle-out without drawing the rest of the beam.

FAQ
- How is the score counted?
- Your score is the highest level of correct landing-zone predictions in a run.
- What are the three choices?
- LEFT, CENTER, and RIGHT — the zone where the laser would hit after the bounces.
- Do the mirrors stay still?
- No. They move, so you must update the predicted path, not memorize one layout.
- Is this a physics exam?
- No. It is a spatial prediction game, not a graded science test.
