My World is a sandbox video game pioneered by Marcus Alexei Poisson (Notch). The game is maintained by Mojang?Studios, now part of Microsoft's Xbox game studio. The Chinese version is now distributed by NetEase Games , which operated on August 8, 2017 in mainland China.

From the beginning of its inception until Jens Bergenstein (Jeb) came on board and took charge of development, almost all of the development of My World was done by Notch. The game's music was composed by Daniel Rosenfeld (C418) and Lena Raine; Christopher Zetterstrand drew the in-game paintings.

The game was originally released on May 17, 2009, as a Classic version, and on November 18, 2011, as an official Java release. My World's gaming platforms encompass desktop devices, mobile devices and game consoles.

The game features players freely creating and destroying different kinds of cubes in a three-dimensional space filled with cubes. Players can play the game in single or multiplayer mode by destroying or creating elaborate buildings and art.

Or collect items to explore the map to complete the game's achievements (progress). Players can also experiment with gameplay such as redstone circuits and commands in creation mode (with cheats turned on).
