I'll go potentially horrific with this one.
Vault 500 would have single sphere shaped room which is completely open including all facilities, no matter how private. Twelve randomly selected people are kept in this room. Through the facilities in this room, people cannot die through aging or disease, even by choice.
There is no entertainment in this room except audio recordings activated by button press all along the wall. There is no control given over these recordings aside from being able to turn them on, and they can be any length. They are heard by everyone in the room, a little too loudly to be blocked out with hands on ears.
The walls are completely soft and nothing can be broken no matter how hard those inside try.
The only way out for all inside is to break a screen saying "BREAK ME" in the ceiling that is far beyond the reach of anything in the room, and with no way of breaking apart an object to obtain reach, it is impossible to reach this thing.
Except through the use of the other people.
If one person were to string everyone else together, having killed them all, they could reach the screen and possibly break it.
Of course, if everyone stood on each other's shoulders at the bottom, that would work too. But will they figure that out before someone has taken a step down the more savage route?
The person or people who succeed(s) will allegedly escape to a larger compound where, the Vault computers say, there are all the facilities that the Sphere Room has, plus privacy and other people who are not effected by the Sphere Room, ready to reward them with all the other kinds of entertainment otherwise forbidden.
Whether or not that story is true, I'll leave to your imagination.
On the other hand, maybe the fun will have only just started...

Isn't that a little bit unfair?
The metal head will clearly win.
