How to play

Starbounce is part builder, part physics puzzle. Each mission hands you a course and a fixed set of parts. Drop a few bumpers, ramps and boosters onto the field to shape the route, dial in your launch angle and power — a dashed line previews your aim — then press Launch.

A single glowing orb fires from the pad, arcs down under gravity, and caroms off everything you built. Sweep it through every star on the board and the level is cleared.

One launch: the orb fires from the pad, arcs up to grab the first star, caroms off a bumper, then rides your ramp up to sweep the last two. Every star lit means the level is done.

The parts you place

You get a limited number of each part per level, so spend them well. Tap the field to drop one; a ramp or booster auto-selects so you can spin it with the rotate buttons to the exact angle you want.

Bumper — a round peg. The orb bounces off it and comes away faster than it arrived. Bumpers are round, so there's nothing to rotate.
Ramp — a straight bar that simply deflects the orb. Rotate it to bank a shot around a wall or set up your next bounce.
Booster — a pad that flings the orb off at full speed in the direction its arrow points. Rotate it to aim, and use it to keep a fading run alive.

Every mission hands you a fixed inventory — a few bumpers, a ramp or two, sometimes a booster. Run one dry and you rebuild with what's left.

What's on the board

Early missions are just the launcher, some stars and a wall or two. Climb the tiers and the board starts fighting back:

Star — a target. Roll the orb through it and it lights up. Collect every star on the board to clear the level.
Launcher — the pad the orb starts on. Its position is fixed, so the whole route has to work from there.
Wall — a solid block the orb bounces off. Bank shots around it, or use it to redirect a bounce.
Black hole — a gravity well that bends the orb's path as it passes. Drift too close and it swallows the orb.
Portal — a linked pair. Enter one mouth and the orb bursts out of the other with its speed intact — the way to reach stars across the board.
Mind the core
A black hole tugs the orb harder the closer it drifts. Its pull can be a friend — curve a shot around the rim to reach an awkward star — but let the orb sink into the dark core and the run is lost. Reset the orb and swing wider.

120 missions & your own

There are four tiers of 30 missions — 120 in all — each one a step up in what the board throws at you:

Easy
Medium
Hard
Expert

Easy missions are pure bounce-and-collect; Medium adds boosters; Hard brings in portals and black holes; Expert threads you between two wells or splits the board in half. Cleared missions are saved in your browser, so you can pick up where you left off. There's also a built-in editor — place your own stars, walls and hazards, set the parts, and play the level you designed.

Tips

  • Build the whole route first, then fine-tune — small angle changes matter.
  • Bumpers speed the orb up, ramps redirect it, boosters fling it at full pace. Chain them.
  • The orb sheds a little speed with every bounce; if a run stalls, add power or a booster before you rebuild.
  • Use Reset orb to re-fire without touching your course, or Clear parts to start the build fresh.
