Scribblenauts Unlimited invites you to immerse yourself in a completely open world, filled with any things that can be recreated with the help of your imagination. Here, taking on the guise of a character named Maxwell, the user is invited to advance through open-world levels, solving the proposed tasks. The peculiarity of this process is that the hero can use absolutely any objects to solve emerging problems. Moving through the story, the player will have the opportunity to find out more about the character, in particular about his parents, brothers and sisters.

The ability to create objects in Scribblenauts Unlimited is made possible by the character's possession of a magical notebook. Thanks to him, everything that appears in his imagination can be recreated on the pages of this notebook. For example, in one of the first segments you need to help the main character's brother win a pig competition. However, now he only has a small pig, unable to compete with other competitors. Therefore, the user will use his special item to increase the specimen in size and also give it wings. In the future, situations will become more diverse, and to solve them it will be necessary to make decisions of a different kind. All created or modified items will go to the library. Each subsequent location is opened by collecting the required number of stars. To do this, you need to help all units located in the current territory. And taking into account the fact that each location is different from the previous one, the tests will take the gamer out of their comfort zone over and over again.
