Asteroids
ArcadeHow to play Asteroids
I rotate my ship with the left and right arrow keys, push the up arrow to thrust forward, and fire with the spacebar. On a phone I hold the on-screen rotate, THRUST, and FIRE buttons.
I shoot the drifting rocks to break them apart. Large rocks split into two medium ones, and medium rocks split again into small ones, so the screen gets busy fast. Everything wraps around the edges, including me, so I use the whole field to line up shots and avoid collisions across my three lives.
About Asteroids
Asteroids is one of the defining arcade games of all time. Atari released it in 1979, and its glowing vector-line graphics and drifting physics made it an instant phenomenon; for a while it was the best-selling arcade cabinet Atari had ever made. You pilot a lone triangular ship in a wraparound field of rocks, blasting them into ever smaller, ever faster fragments.
The genius of the design is momentum. Your ship does not stop when you release thrust, it keeps drifting, and every shot you fire at a big rock creates new, faster hazards. The game constantly trades short-term safety for long-term chaos, and learning to manage that trade is the whole sport. This version keeps the classic feel with keyboard controls on desktop and touch controls on mobile.
Asteroids survival tips
- Feather the thrust in short taps. Holding it builds speed you cannot shed quickly, and speed is what flies you into rocks.
- Clear rocks in a controlled order: pick one large asteroid, destroy its fragments completely, then move to the next.
- Use the screen wrap deliberately. Slipping off one edge to reappear on the other is often the cleanest escape route.
- Never fire into a crowd at close range. Splitting a rock next to your ship turns one slow hazard into two fast ones.
- When a flying saucer appears, make it the priority. Its shots are more dangerous than any drifting rock.
FAQ
Why does my ship keep moving after I stop thrusting?
That is the original 1979 physics, faithfully kept: space has no friction, so your ship coasts until you counter-thrust in the opposite direction. Mastering that drift is what separates long runs from short ones.
What is the safest way to deal with big asteroids?
Shoot them from a distance and immediately track the two fragments they split into. The medium and small rocks move faster than the big ones, so the moment after a split is the most dangerous.
Does Asteroids on this page work on a phone?
Yes. On mobile you get on-screen controls for rotate, thrust and fire, and the canvas scales to your screen. On desktop you can use the arrow keys and spacebar.
Is there an end to Asteroids?
No final level, no ending. Each cleared wave spawns a bigger, faster one, and the game continues until you run out of ships. The score is the only finish line, and your best is saved in your browser.
