Overview
Magic Number is a nine-digit numeric code used to generate the terrain of a Cloud Island in Pokemon Pokopia. It works like a world seed in sandbox games: the same Magic Number always produces the exact same landmass, elevation, coastline, and water placement. It does not copy any furniture, habitats, buildings, or items placed by other players on their version of that island. Only the raw terrain is determined by the Magic Number.
Magic Numbers are specific to Cloud Islands, the blank shared islands introduced as a multiplayer creative space. Story islands, Palette Town, and Dream Islands do not use Magic Numbers.
Generating a Magic Number
Complete the tutorial and reach Environment Level 2 in Withered Wasteland to unlock Link Play at the Pokemon Center PC.
Open the PC, select the Link Play icon (a Ditto emblem), then select Create Cloud Island.
Choose "Generate a Random Cloud Island" to create a new island with a random Magic Number. The game displays the assigned nine-digit number on the summary screen.
Alternatively, choose Generate via Magic Number and type in any nine-digit number to produce a specific terrain.
Checking Your Magic Number
If you did not write down your Magic Number when the island was created, you can find it later:
Open the Pokemon Center PC and select Link Play.
Select Check Settings from the submenu.
Select Cloud Island Settings. The Magic Number is listed alongside other island details.
Sharing a Magic Number
Magic Numbers are how players share the same terrain without needing to be online at the same time. A typical workflow:
A group of friends picks one Magic Number and agrees that everyone will create a Cloud Island using that seed.
Each player creates an island with the identical Magic Number. All of their islands have the same geography.
Players can then build their own versions of a town on top of the same terrain, or collaborate through Link Code visits on one shared instance.
Magic Numbers are also popular in online communities as a way to distribute high-quality terrain layouts. If a content creator finds a Magic Number with a picturesque coastline and mountain range, they can share the number and other players can instantly visit an identical landmass.
What Magic Numbers Do Not Do
They do not copy any built structures, habitats, furniture, or items from someone else's Cloud Island.
They do not transfer Pokemon populations. Cloud Island Pokemon are generated locally based on which habitats you build.
They do not share progress. Each player's Cloud Island is their own save; visiting via Link Code is separate from creating one with a matching Magic Number.
They do not affect story islands or Palette Town. Those areas have fixed terrain.
Tips
Write down the Magic Number the moment you create an island you like. You can delete and recreate a Cloud Island later using the same number to reset any unwanted changes.
When sharing with friends, confirm everyone enters the same number. A single mistyped digit produces a completely different island.
Only one Cloud Island per host exists at a time. If you want to try multiple Magic Numbers, delete the current island first (you will lose anything built on it).
Cloud Islands do not contribute Pokemon to your main Pokedex, so Magic Number terrain is purely a creative canvas.
