Title of a film similar to House of 9 (but better!)

Hi all,

First off, apologies for my first post being a question about the title of a film! I'm usually great at remembering titles! However, this time, after 3 or so hours searching Google and looking at Amazon etc. recommendations/similar films, I've still not come up with anything.

Also, apologies if it isn't actually a British film - I cannot remember for sure. It was fairly modern (maybe straight to TV/DVD?) and it was shown on one of the main 5 TV channels in the UK in March/April in either 2008 or 9.

To the best of my memory...
The film consisted of 5 or 6 teens/twenty somethings in a large house which was in the middle of a large enclosed compound/grounds, and took place in winter (snow). I cannot remember how they got there - I think it was probably a psychology experiment, not something like Saw as in punishments/lessons etc. Eventually they realise that they must escape the house as there seems to be not much happening, despite there being food parcels dropped fairly often in the grounds of the property. I believe they catch a glimpse of an outsider/the organiser at some point delivering this, but I do not remember the outcome. They also know that they are on CCTV for all of what they're doing. At some point, a computer wiz manages to crack a website which has direct live feeds of them in the house, and find that some rather sick people are gambling on the last one living. Needless to say I'm pretty sure all but one person gets killed off once they realise this in a mad fight for your lives finale.

I'll try and answer any questions anyone may have, but I'm desperate to get this on DVD as I really enjoyed it at the time and it's really winding me up not being able to remember the title!

Thank you in advance.

Genius! Thank you that man!
I didn't realise it was coming up 10 years old - either way a bargain at less than £4 on Amazon.
Thank you so much again!
