Grab a planet. Give it an orbit. Grow a galaxy.

Catch a drifting planet with your mouse, guide it toward an orbit, and let go. PLANETOON is a space puzzle game where a simple action can set a whole universe in motion.

Choose where to welcome each planet and how far to spread your orbits. Every placement helps shape the galaxy taking form before you.

Nurture life. Watch it reach for the stars.

Life can emerge on your planets, grow into civilizations, and reach out to other worlds. Some may even leave their home planet and embark on a journey of their own.

Watch the planets turn, and follow the changes unfolding in the universe you helped create.

Beyond the next orbit, something unexpected.

Planets, UFOs, black holes. A variety of celestial objects and visitors brings unexpected encounters and changes to your galaxy.

Some rare phenomena can only be found as you extend your orbits farther out. A beautiful arrangement of planets, a surprising encounter: each discovery gives you another idea to try in your next galaxy.

Over 60 endings. More space to create.

Guide your galaxy toward 12 billion years of history. How you nurture it, and the events you encounter, can lead to over 60 different endings.

Collect every ending to unlock Endless Mode, then keep building beyond 12 billion years.

A galaxy of your own, shaped by your hands.
