Grav
well

Fire a spark. It drifts, slows, then swells until it touches something. Every bubble takes three hits to burst, and a burst blasts its neighbors. Let a spark fall back below the Kármán line, the edge of space, and the run ends.

Advanced

Classic Gravity

Space starts flat. Every bubble bends it and pulls passing sparks toward its edge, harder the bigger it grows. No bouncing in this mode: a spark that touches a bubble hits it and locks there, spark-sized.

Rewinds

Off 3 per run

A rewind undoes a lost shot and puts the board back the way it was.

Play

Your best with these settings: 0

• Aim with the mouse, or drag a finger. Arrow keys work too.
• Fire with a click, by lifting your finger, or with Space.
• Chain bursts: each burst in one shot is worth 10 more than the last.

Paused

Spark burned up on reentry

It fell back below the Kármán line. Rewind to just before that shot and try a different angle.
