How to play: Your starship sits in a drifting asteroid field. Rotate with ← and →, fire the main thruster with ↑, and shoot with the space bar (WASD works too). On phones, use the on-screen thruster and fire buttons.
Classic starship arcade: rotate, thrust and blast the asteroids before they crush you. Big rocks split into fast little ones — and watch for the saucer.
Desktop: ← → rotate, ↑ thrust, space to fire. Phone: on-screen thrusters.
← → rotate · ↑ thrust · space to fire (WASD works too) · on phones use the on-screen thrusters · rocks split when shot — small ones are worth the most.

How to play Space Rocks
Your starship sits in a drifting asteroid field. Rotate with ← and →, fire the main thruster with ↑, and shoot with the space bar (WASD works too). On phones, use the on-screen thruster and fire buttons.
Shooting a big rock splits it into two medium rocks, and each medium splits into two small ones. Small rocks are fast — and worth the most: 20 for large, 50 for medium, 100 for small.
The screen wraps on every edge, for you and the rocks alike. Every so often a saucer crosses the field taking pot-shots at you; it’s worth 200 if you can hit it.
Clear the field to start the next wave with more rocks. You have three ships; a fresh ship spawns with a short shield.
Tips & tricks
- Drift is your friend: short thruster taps beat holding the burn — momentum carries you and there are no brakes.
- Never split a big rock while you’re close to it: the two mediums fly off in random directions, often straight at you.
- Use the screen wrap offensively — shots wrap too, so you can hit rocks across the edge.
- When the saucer shows up, keep moving sideways; its aim leads slow targets.
