Space Racer: Thread the Asteroids
Four lanes of deep space, asteroids inbound from the right. Drag between lanes and fly as far as your nerve allows.

Drag up or down to change lanes. Arrow keys work on desktop.
How to play
- Commit to lane changes early — the glide takes half a second.
- Track both your current lane and your target lane before switching.
- The top and bottom lanes have fewer neighbours, making them safer corridors.
- Bonus distance for every asteroid passed — near misses pay.
- Late-game spawn waves come in clusters; pre-plan two moves ahead.
About this game
Space Racer puts the endless-runner formula sideways. Your ship holds steady on the left of the screen while asteroids stream in from the right across four lanes, and your only control is sliding up and down to change lanes. Distance ticks up continuously; every asteroid you thread past without touching adds bonus distance.
The lane system is what gives this game its character. Instead of free movement, you commit to one of four discrete lanes, and the ship eases between them with a soft animated glide. That half-second of transit is where every crash happens — switching lanes into an asteroid that was already occupying your target lane. Good players track two lanes at once: the one they are in and the one they are committing to.
Speed and spawn rate climb together, so the lane rhythm that feels generous in the first minute becomes a real test by the third. The visual style stays dark and readable: a starfield scrolls by, asteroids tumble with irregular silhouettes, and the little ship leaves an orange thrust trail whenever you commit to a move.
Everything is one-finger playable, runs are measured in minutes, and your best distance is saved locally. It is the calmest looking game in the catalogue that will still make you flinch.
Frequently asked questions
How many lanes are there?
Four. The ship eases between them with a short animated glide, and crashes happen during that transit.
How is distance scored?
Continuous distance plus bonus distance for every asteroid you pass safely.
Do asteroids move between lanes?
No. Each asteroid stays in its lane, which makes every wave readable in advance.
Does the game save my best run?
Yes, locally on your device, with no account needed.
