How do i make a game inside another game?

On some games you can play the main game and then you can teleport to a different game but if oyu look at it it says "This game is apart of (Games name here)" i whant to knwn how to do that? Example of this is "Doragon's Garden" on the home menu of teh game you can teleport too two other islands.

In order to teleport a player from place to place, you must use Universes and Teleport Service. Universes were recently released, so if you ask most people for you help you may not get an answer.

Begin by reading this blog post which describes the universe system and provides links to numerous wiki articles. After that, if you have remaining specific questions about the implementation, ask again! :) Good luck to you!
