Astro Rebound

One elastic band. A lost planet. A wormhole to reach.

Astro Rebound is a small space-themed physics puzzle. Draw an elastic band, adjust its position and angle, then launch the planet and watch your plan unfold.

Bounce off asteroid walls, return to the same spring, and chain redirects to reach the wormhole. Collect up to three star fragments along the way, or focus on getting the planet home — stars are optional.

Features

• 30 levels, all available from the start.
• One adjustable elastic band per puzzle.
• Gravity, spring rebounds, and asteroid ricochets.
• Three optional star fragments in every level.
• Quick retries that keep your band in place.
• Progress saved locally in your browser.

How to play

1. Click and drag on the playfield to draw a band.
2. Drag either endpoint to change its angle or length, or drag the band itself to move it.
3. Click the triangle button to launch the planet. Click it again to retry with the same band.
4. Reach the wormhole to complete the level. Use × to remove the band and ☰ to choose another level.

On a touchscreen, use one finger for the same gestures and tap the buttons.
