I could be wrong stefan, but I think that, when the game shows you all the presents being switched around just before it puts the wrapping paper on, that that's all forshow and has nothing to do with the actual position of the presents. Even if you somehow did manage to see which present was where just before the wrapping was put on it probably won't be there when you pick it. I think each time you pick a present it is just randomly picked from the remaining presents, regardless of where you click. The developers have done this sort of stuff before (though perhaps not this exact same thing), but the player base persists in believing that they can somehow outsmart a graphical artifact that has no effect on the prizes. People see patterns, even when they aren't there.
