[Hello, World]

Hello, World is a level in the video game World of Goo. It is the first level of Chapter 4. In this level, Square Goo and Launch Goo are introduced. The player must learn how to use Launch Goo to make them launch from one Goo structure to another one one over a chasm, and then build to the pipe.

10 Goo method

If you stretch the Goos far enough to the pipe, you can use two Goos to reach the pipe.


The level just teaches you how to launch Goo. No real strategy is needed.

OCD Strategy

Use the 10 Goo method to get to the pipe a little faster, and only launch who you need. Otherwise, be fast.


  • The title of this level is a reference to the "Hello World" program.
