I want to make it so that a player can only go into a game from another game. A game where in has a intro and guis and when you press play it will teleport u into another game. I understand how to do all of this but how do I make it so that the game that I want the player to go into is only available to go into by using the intro game and not by using the Roblox browser and pressing play. I'm not asking for a script i'm just asking for maybe a link to the wiki or a good example and summary of how to do it.
