Also called, "The Elevator Game", it's a sequence of pressed buttons on an elevator that's supposed to transport the player to another dimension. The sequence of the buttons and movements are as follows:
"You need an elevator at least ten stories high. You enter the elevator, which must be empty, on the first floor. Then, you press the 4th floor button. Upon reaching the 4th floor, you press the 2nd floor. On the 2nd floor you press a button for the 6th, when you get to the 6th floor you press the button for the 2nd floor again. Upon arriving at the 2nd floor, press the button for the 10th. When you reach the 10th, you press 5.
Now, when the door opens on the 5th floor, a young woman may enter the elevator. You must not look at or speak to her. At this point, you press the 1st floor button. If the elevator starts moving up to the 10th floor instead of down to the 1st, you may keep going. If, however, the elevator starts moving down, get out as soon as possible and under no condition look back at, or speak to, the woman. If you reach the 10th floor, however, you may either choose to stay in the elevator or get out. If you get out at this point, the young woman will ask you where you’re going. Do not answer or look at her. You’ll know you’ve reached the other world if you’re alone. At some point you’ll pass out, and when you wake up, you’ll be somewhere else. If you make it to the other dimension there is actually a way of coming back. All you need to do is press the buttons in the opposite order, not speak to or look at the woman. " You might never come back, so think it through before you do it.
The game was described in Episode 103, as a theory behind the apparent suicide of a young woman whose body was found in the water tower of the Cecil Hotel in Los Angeles in 2013. Video footage from the elevator the evening she was believed to have disappeared shows her pressing a sequence of buttons, exiting and entering the elevator, and she appears to be hiding from someone unseen by the camera.
