Can you please explain the film "Cube" to me?

Question

In the first film, it seems like they have just thrown random people in, and then the guy walks out into the sunset.

In the second film, it seems as though convicts on death row are choosing between the cube and death... with a weird secrecy thing going on upstairs... but when they escape they go to the middle of nice country etc.

and in the third... h**l knows! some woman survives and appears in a room full of people, gives someone her necklace and then is shot!

where is the cube?

why did they make it?

what purpose does it serve???

and in the third

Answer 1

um. its a cube. yeah. and its a film "cube" at the same time. i know its disturbing.

Answer 2

The director of the first film, Vincenzo Natali, made a follow-up short film in which we see what is outside the cube. Natali has made a solemn vow never to reveal what was outside the cube, and destroyed the video years ago.
