Fire streams of bouncing balls into numbered blocks and excavate a route toward a planet's core. Each expedition gives you a limited supply of shots, so a good angle matters more than simply hitting the nearest target: squeezing balls into a narrow gap can produce repeated ricochets that wear down several blocks at once. Some blocks are anchored to the walls, changing which obstacles you can remove efficiently. Crystals collected underground fund permanent upgrades, letting you choose between more balls, additional shots, and greater storage capacity. Six procedurally generated planets provide progressively deeper expeditions, while an endless mode shifts the goal from reaching a destination to extending a run.
