The World of Goo Corporation is a sandbox level in World of Goo, which allows the player to build towers and structures using a maximum of 300 Goo Balls.
A competition occurs between World of Goo players, with each player attempting to create the highest towers using their 300 Goo Balls. Currently, the highest record is just over 50m.
Some players have developed cheats to be able to use more then 300 Goo Balls, although these cheats normally does not allow scores to be sent. However, some players have made drastic modifications to create tall towers using a ridiculously little amount of Goo Balls, such as five (5), in order to cheat the leaderboards, a section on World of Goo's official website which records the highest towers built.
