The game is built around the idea of creating different shapes with the Goo balls. The game consists of four chapters and an epilogue, each containing several levels. Each level has its own graphic and musical themes, which give it a unique atmosphere. There is also a bonus level, called World of Goo Corporation, where the goal is to build high towers with extra goo balls which the player has collected in the passing game. Players from all over the world can compete in the height of the towers because the tower is loaded onto a special server. The main objective of the game is to bring the required number of Goo balls to the pipe, which is the output. To do this, the player must use the goo balls to construct bridges, towers and other structures to overcome gravity in different places, such as caves, hills, precipices or cliffs. All the balls that the player has collected in excess of the required at this level are sent to the World of Goo Corporation. There are several types of goo balls, each of which has unique properties. The player must combine them to complete each level.
