As for how they can work out who did it, just search for someone with a .exe that isn't on the safe list. It will always link back to you.
Your only real chance would be a Live CD/usb with the game already installed. That limits you to linux tbh. You'd have to make sure it doesn't modify any of the systems files too. The only issue would be explaining that it doesn't do anything when you are inevitably caught playing on a game, but at least you have some form of defence. 90% of teachers would instantly want you kicked out in my experience.
