Pilot a ship through a wrapping asteroid field. Touch and hold to aim, thrust, and auto-fire.
Touch and hold anywhere on the screen. The ship rotates to point at your finger, thrusts forward, and auto-fires every 0.25 seconds.
Release to coast — the ship keeps its momentum (no friction in space). Move your finger to a new spot to change direction; the ship will swing around and accelerate toward the new heading.
The arena wraps: ships, bullets, and asteroids all leave one edge and reappear on the opposite edge.
Asteroids come in three sizes:
• Large = 20 points. Shooting a large one splits it into two mediums.
• Medium = 50 points. Splits into two smalls.
• Small = 100 points. Destroyed clean.
Clear every asteroid to advance to the next wave (one more large, slightly faster). Touching ANY asteroid with the ship ends the game. Score = sum across waves.
Inertia is your enemy until you learn to use it. Beginners hold the finger down constantly and end up screaming across the screen into the next asteroid. Tap-release-tap-release to manage speed: short bursts of thrust keep you maneuverable; long bursts get you into trouble.
Use the wrap. The screen wrapping is a free teleport — bullets that leave the right edge instantly threaten asteroids near the left edge. When surrounded, aim near a screen edge to fire 'around the world' — sometimes your own bullet wraps and hits an asteroid behind you.
Kill big rocks last. Counterintuitive but real: small asteroids are worth 5x what large ones are (100 vs 20), and a single screen full of small fast-moving rocks is much harder to navigate than a few slow giants. If a wave is otherwise calm, take out the smalls first for score, then mop up the larges.
Don't fire constantly into open space. Auto-fire continues whenever you're holding — bullets near you can occlude your view of incoming asteroids. Release your finger briefly when no asteroid is in your line of fire; the moment of quiet helps you reassess.
