How to play Rebound

Aim one shot so the ball bounces off the walls and picks up every star.

Goal

Aim a single shot so the ball bounces off the walls and collects every star.

Set your aim with the angle slider. The ◀ / ▶ buttons nudge it by 0.1° for fine adjustment.
The dotted guide line shows the start of the ball's route. On harder levels it shows fewer bounces.
Press Shoot. The ball bounces off the walls and obstacles at equal angles, like a billiard ball.
Collect every star before you run out of shots. Each unused shot earns bonus points.
After each level you get a short physics fact about the bounce you used.

Keys	What it does
`←→`	Nudge the angle slider once it has focus (click it first)

Work backwards from the star: imagine a straight line bouncing off the wall it would need to hit.
Small angle changes matter a lot after several bounces. Use the 0.1° buttons.
On Easy and Medium, “Show the path” and “Auto-aim” are available, but they reduce your score.

Clearing a level is worth 100 points, scaled by difficulty (Easy ×0.8 up to Expert ×1.6).
Clearing it within 12 seconds adds 25 points, each unused shot adds 20, and each level cleared in a row adds 15 (up to 10).
If you fail a level, you still get 10 points × difficulty for every star you collected.
Using a hint halves the points for that level. Hints are only available on Easy and Medium.
