From Blockate Wiki

Worlds are the individual creations of players in Blockate. It costs 500 Blux to make a Blockate world, but the first world you create is free, and you can also obtain another free world for joining the Roblox Blockate group

If you want to share your Blockate world with friends, you can use the following link:, with WORLDID replaced with your worlds id that is found by using the command !id. Anyone who clicks the link will be sent to your Blockate world without having to do anything. Example:

Without a thumbnail for your world, the thumbnail will automatically change as your block count goes up.
