Orbit Well: Gravity Pool

Pool, played around a star.

Planets circle a star on three orbits. You have a comet and a handful of shots. Hit a planet against the direction it travels and it slows, its orbit decays, and it falls into the star. Hit it along its orbit and it speeds up and climbs away instead. Sink every ringed planet before the shots run out to clear the rack.

Every shot is real orbital physics. The outer orbit is a long way down, so it takes a harder strike. Planets on different rings move at different speeds, so you lead your target the way you would a moving ball.

See the shot before you take it
Drag to aim and the guide traces the comet's whole path, marks where it will meet its target, and tells you whether that strike sends the planet falling inward or climbing outward. Bank off the rim when the direct line is blocked.

Racks that teach, then racks that never end
The first twelve racks are hand-built, each with one idea to learn: striking against the grain, the long fall from the outer ring, one comet carrying through two planets, rings turning in opposite directions. After that the racks keep coming, fuller and tighter, for as long as you last.

Power-ups
• Retro Burn — slows every planet at once, so each orbit falls a notch
• Singularity — pick any planet and pull it into the star; earned by clearing a rack with shots to spare
• Extra Shot — one more comet; earned by sinking two or more with a single shot

Come back every day
• Daily Challenge — the same rack for everyone, with streaks
• 20 awards to earn, from your first sink to a fifteen-round run
• Chase your record, shown live as you play

Made for quick sessions
A rack takes a minute or two. Plays offline, one-handed, in portrait. Every planet is drawn as you play and every sound is generated on your device.
