Minecraft is about placing blocks to build things and going on adventures.

Pocket Edition includes Survival and Creative modes, multiplayer over a local Wi-Fi network, and randomly generated worlds. You can craft, create and breed anywhere in the world so long as you have hands spare and battery to burn.

Since the first release of Minecraft: Pocket Edition, we’ve added heaps of new features and made massive improvements to the way things look. There’s never been a better time to enjoy Minecraft on the move.

Minecraft — Pocket Edition is a Universal App. Pay once and play on any of your Android devices.
