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.
Finish one rock family before cracking the next. Small rocks only exist because you broke something bigger: every large rock becomes two mediums and then four smalls, and the whole family is worth 520 points (20 + 2×50 + 4×100), most of it from the smalls at the end. The score is the same whatever order you shoot in, so the order is purely about safety — split one large, clean up its fast little pieces while you can still track them, and only then start on the next. A screen full of small fast rocks from three broken families is much harder to survive than a few slow giants.
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.
