*goto_random_scene acts as an extension to the *goto_scene command. The primary difference being that *goto_random_scene will send the player to a (you guessed it) random scene.
You can use the command 'as is' to send the player to any random scene in your scenes folder or you can provide parameter scenes (as in the example below). Regardless of which method you choose keep in mind that Choicescript will keep track of scenes it has randomly selected and will not pick them again during that playthrough (although it will still allow access through use of *finish or *goto_scene).
