BuildMyPlanet

Your world grows with friends.

A free block-building game where you explore the real Earth and grow your own planets with friends, with a parent-PIN Kid mode. Planets grow through play and are never bought.

  • App Store · Coming soon

// Overview

The menu is the planet. It spins behind one big Play button, and the world streams in while you dive.

Pick a hometown from 80+ cities and wonders, skydive in, and start building with friends. Whatever you make, your planet grows with the time you spend together, never with money.
