I just won a journal and wrist cuffs to go with the game from a couple days ago. I was actually shocked, as it came on my third code today on the same email I won with the first time, and since the slight delay before the coin came up that I had the first time I won wasn't there. I guess that little hitch doesn't mean anything.
One thing I will say though, is that for the first week or so of the game I played my codes pretty much at midnight and didn't get anything. Since I've switched to waiting until I woke up in the morning I've won 2 out of 4 days, once at about 4:30 AM eastern and about 7:15 AM, so it almost seems to me that the prizes are set to show up sometime after midnight has passed across the country.
