Although the game generates random seeds using combinations of specific words and numbers, any characters (alpha, numeric and most common keyboard symbols) can be used and spaces do count, however a built-in word filter will automatically exclude any forbidden words, causing the game to revert to a random seed instead. Once the player has the ability to generate random worlds, the game will generate random worlds of whatever size the player has unlocked whenever the player clicks the 'Find Random World' symbol on the Galaxy Map, however, the player can also choose to generate ('Locate') a world based on a set of Galactic Coordinates, or even (after they unlock the ability), the player can create custom worlds based on their own specifications.
LEGO Worlds will automatically generate the first world in Adventure Mode, a simple tutorial called ( Pirate Playground), and will continue to generate tutorial worlds (such as Prehistoric Peril (Tutorial) and Candy Construction Capers (Tutorial)) until the player completes the tutorial levels and moves on to random worlds. Before playing, the Player needs to generate a World to play in.
