The most obvious answer is 'Battle Royal' by Koushun Takami. It's not quite what you are after, so I'm thinking a knock off copy very much like 'The hunger Games'. You could try Googling "Books similar to..." and see if anything familiar pops up.
That is it. I could see the cover but couldn't make out the title. I knew there were at least three books. Thank You
