Planet Merge

Planet Merge turns a patch of night sky into a physics playground. You flick small worlds into a crowded arena and then watch gravity, spin and every neighbouring rock decide where they finally come to rest.

Whenever two identical planets touch, they collapse into a single bigger world. Follow that chain upward and a handful of space pebbles slowly becomes rocky planets, and eventually ringed giants.

Space runs out faster than you expect. Keeping matching worlds within reach of one another, refusing to waste an empty corner, and timing each shot are what separate a short run from a spectacular one.

Hold the mouse button to line up a shot, move to adjust the angle, then release to fire.

On a phone or tablet, press and hold anywhere on the screen to aim, then lift your finger to launch.

Aim at a planet of the same type so the two collide and fuse into the next size up.

Keep merging as the board fills, and try to leave yourself open space to work with.

Two worlds of the same kind vanish on contact and leave a single larger planet behind. That new world becomes its own tier, so pairing it with another copy pushes you one more step up the ladder.

A planet rarely stops where you drop it. It rolls, bounces and gets nudged by whatever is already on the board. A precise shot puts the world where you actually want it and keeps the pairs you planned from drifting apart.

Park matching worlds next to the spot where your next merge will happen. When a collision produces a larger planet right beside its twin, the following merge fires on its own, and a well-stacked arena can keep that cascade running through several tiers.

Think two or three launches ahead instead of reacting shot by shot. Gather same-size worlds in one region, spend your big merges when they will trigger something else, and keep the arena tidy so you always have somewhere left to shoot.
