In Scribblenauts, the player uses the touch screen to help their character, Maxwell, acquire the starite in each level by solving a series of puzzles. The twist is, in order to solve the puzzle, the player uses the stylus and notepad to write down the word for any object that comes to mind in order to reach the goal. Every object behaves as it would in the real-world, and the player can combine countless objects together to create completely new behaviours. Every level has more than one written object to use as a solution, opening up the game to unlimited replay.
