Asteroids is the 1979 Atari arcade game that defined the vector-graphics era. Designed by Lyle Rains and Ed Logg, it sold over 70,000 cabinets and became Atari’s most successful arcade title. A small triangular ship floats in inertia-physics space; large asteroids drift in random directions; shoot them to break them into smaller asteroids, then into debris. A flying saucer occasionally arrives to shoot back. The game’s relentless physics, infinite playfield wraparound, and crisp vector visuals made it a defining game of its era.
How to play
- Left / Right arrows — rotate the ship.
- Up arrow — thrust forward (inertia keeps you moving).
- Space — fire bullets.
- Shift / Down — hyperspace (random teleport, risk of self-destruct).
- Shoot large asteroids to break them into 2 medium asteroids; mediums break into 2 small asteroids; smalls vanish on hit.
- Clear all asteroids on screen to advance to the next wave.
- UFO appears periodically and shoots back. Worth bonus points if destroyed.
- Screen wraps — exit one side, enter the other.
- 3 lives. Crashing into an asteroid or UFO bullet ends a life.
Scoring
- Large asteroid → 20 points.
- Medium → 50 points.
- Small → 100 points.
- Large UFO → 200 points.
- Small UFO → 1,000 points.
- Bonus life every 10,000 points (in most ROM versions).
Beginner strategy
- Stay near the centre. The screen-wrap can save you, but the centre gives you the longest reaction times to incoming asteroids.
- Don’t thrust unnecessarily. Inertia is fatal. Every thrust commits you to a trajectory that takes time to reverse.
- Shoot, don’t dodge. Asteroids are predictable in trajectory. Always prefer shooting an incoming asteroid over evading.
- Hyperspace is a panic button. Use only when about to die. Hyperspace has a small chance of materializing inside an asteroid (instant death) — don’t use it as a strategy.
- Save score for UFOs. UFOs give 200-1,000 points. They appear once or twice per wave. Position yourself to one-shot them.
Intermediate strategy
- Bullet management. Most Asteroids variants limit you to 4 bullets on screen at once. Don’t spray — make each shot count.
- Asteroid prioritization. Shoot the closest threat first. The asteroid drifting away is not urgent; the one heading at you in 2 seconds is.
- Cluster control. Breaking a large asteroid into mediums increases the on-screen count from 1 to 2. Mediums into smalls = 1 → 2 again. A wave that started with 4 large asteroids can momentarily have 16 small ones. Manage the explosion.
- Saucer behavior. Large saucers fire randomly. Small saucers aim AT you and get better aim over time. Kill small saucers first.
- Use thrust as a position swap. Need to be on the other side of the screen? Brief thrust upward + screen wrap = a teleport without the hyperspace risk.
Advanced strategy and the “lurking” technique
- The “lurker” technique. Late in the original Asteroids ROM, expert players would clear most asteroids but leave 1-2 small asteroids permanently. They’d then “lurk” — staying motionless in a safe spot, waiting for UFOs to spawn — and farm UFO points indefinitely. The game’s bonus-life system rewards this enormously.
- UFO baiting. Position your ship in a predictable corner. Small saucers will lock onto you, then you rotate at the last moment and fire.
- Reset trick. On the original Atari cabinet, holding certain button combos at boot would reset the high-score list — useful for tournament purposes only.
- 14,000,000 record. The all-time Asteroids record (Scott Safran, 1982) is 41,336,440. Safran spent 27 hours achieving it. Modern lurker-strategy players have approached this number but Atari modified ROM in later versions to prevent infinite lurking.
The vector graphics era
Asteroids used a vector display (Quadrascan) instead of a raster (pixel) display. Vector displays draw lines between coordinates rather than filling a grid, giving the crisp, glowing geometric look characteristic of late-1970s arcade titles. Vector arcade games (Asteroids, Battlezone, Tempest, Star Wars) had a unique aesthetic — but vector hardware was fragile and expensive. By the mid-1980s, raster displays dominated and the vector era ended.
Asteroids in pop culture
- 1979-80 first year: Asteroids cabinets generated more revenue than Space Invaders. The most successful U.S. arcade game until Pac-Man dethroned it.
- 1991 — Asteroids: Time Pilot: Atari attempts a sequel/update with mixed results.
- 2008 — Greatest Hits Volume: Atari includes Asteroids in nostalgic compilations across platforms.
- 2018 — Asteroids: Recharged: modern update with online multiplayer and modernized visuals.
- Cultural footprint: the triangle-ship-and-rocks aesthetic became shorthand for “retro game” for decades.
Common mistakes
- Spamming thrust. Inertia builds up; you can’t stop on a dime. The most common cause of death.
- Shooting recklessly into clusters. Breaking large asteroids near other asteroids doubles the on-screen threat instantly.
- Lingering in the wrap zone. Edges look safe — until an asteroid wraps in behind you.
- Using hyperspace early. The teleport-into-asteroid risk is real. Save it for last-second escapes.
Variants and successors
- Asteroids Deluxe (1981). Adds Kill Saucers — small flying triangles that hunt the player. Harder; less popular than the original.
- Space Duel (1982). Two-player Asteroids with cooperative or competitive modes.
- Blasteroids (1987). Asteroids with a story mode, branching paths, and 3-ship players.
- Sinistar (1982). Williams’ similar-genre game with a hunting boss enemy.
- Modern indie successors: Geometry Wars, Beat Hazard, Resogun all owe heavy debts to Asteroids’ physics and screen-wrap mechanics.
FAQ
- Q: What’s the highest score recorded? A: 41,336,440 by Scott Safran in 1982 — held for decades as one of arcade’s most enduring records.
- Q: Can I play Asteroids without thrust? A: Yes — pure rotation-and-fire is a valid (and easier) strategy for survival, though it slows scoring.
- Q: Why does the ship wrap around the screen? A: Asteroid simulates “space” with no walls. Both your ship and asteroids wrap, creating constant 360° threat.
- Q: Was Asteroids the first vector game? A: No — Lunar Lander (Atari, 1979, slightly earlier) was. But Asteroids defined the vector arcade format commercially.
For other arcade classics, try Space Invaders, Galaga, Centipede, or Pacman.
