Microsoft Store Give Away Details

Does anyone know if the play once per day is per store as well? There is a kiosk store and a b&m store both fairly close to my home. I might run to both tomorrow, but if you can only play once total I will only go to one of them.
I'm not telling you to be dishonest, but the T&C say you are only allowed to play once/day. Just be sure to use different emails and phone numbers if you try more than once/day...

I know, I'm ruining it for everyone else, but you won't win anyhow, so go nuts.
 
I won a red 1520 yesterday. I was one of the first 6 and all the others before me won. I also got the where did cortana originate from question.
 
I know I shouldn't have had expectations of winning anything, but I was number 8 in line on Saturday and the first 7 ALL won. Then I lost.

I arrived this morning (Sunday) very early and was 2nd in line. I lost.

Idk...just feels...not random.
