🤸 Planet Pile Cosmos

Planet Pile Cosmos turns simple physics into a moreish challenge — you stack tiny planets inside a cosmic dome, packing as many as gravity will allow before overflow. Wrapped in deep neon-violet tones, it keeps the focus squarely on the gravity and collisions at the heart of the action. The balls are real colliding bodies — they roll, nudge and settle against each other, so a careless drop can start an avalanche. Every drop shifts the whole pile, so reading the heap and choosing your spot is the difference between a tidy tower and a spill. It starts gently and grows nerve-wracking as the stack creeps toward the overflow line. That tense moment when a wobbling pile somehow holds is exactly what keeps you dropping one more. Nothing is locked behind ads or accounts; open the page and the physics playground is yours. It scales smoothly from phone to desktop, so it plays just as well on a quick break as on a big screen.

How to play

• Tap to start dropping.
• Move your pointer to aim each drop.
• Release balls so they stack and settle.
