Winners outside of the US?

Hi I'm from Australia and was just re-reading the rules.

It says must be a US citizen to claim the prizes.  Was this a recent change?  I read the rules a couple of years ago and it didn't say that. (I'm pretty sure)

If I was to win could I have a friend claim the prize who lives in US?

Also this was king of funny: "If a Canadian resident is deemed eligible to win a prize, in order to be awarded such prize, the Canadian resident will be required to correctly answer a time limited mathematical skill question."

Its always been Canadians and Americans are only eligible for prizes. You are ineligible to win because you are from Australia.

So how did you win the big prize Tuppy?  It say's your from Japan.

Also: If I was to win could I have a friend claim the prize who lives in US?

Tuppy was living in Canada when won

I was living in Canada at the time. I am pretty sure that you have to be a resident of Canada or the US.....so a friend would not be able to pick up the prize for you.
